TL;DR
- Lottie animations render vector motion graphics directly in the browser - lightweight JSON files that scale infinitely without quality loss and stay sharp on every device.
- Appsrow designs, exports, optimises, and integrates Lottie animations into websites, mobile apps, and product UIs - across Webflow, React, Next.js, iOS, Android, and Flutter.
- Services include custom animation design, After Effects to Lottie conversion, performance optimisation, interactive scroll and hover triggers, and dotLottie packaging.
- Every animation is built for performance - typically under 50KB, GPU-accelerated, and rendered at smooth 60fps even on low-powered mobile devices.
- The result is a website or app with motion that feels native, loads instantly, and stays crisp at any resolution - without the file size of video or the limitations of GIFs.
- Implementations support all major Lottie players - lottie-web, lottie-react, lottie-ios, lottie-android, and the modern dotLottie format with built-in compression and theming.
- Clients typically replace bulky video and GIF assets with Lottie files that are 80-95% smaller while looking dramatically sharper across all screen sizes.
Static Sites Are Forgettable. Motion Makes Products Feel Alive. Appsrow Delivers It.
Lottie is an open-source animation format created by Airbnb that renders vector animations from a lightweight JSON file. Instead of shipping a heavy MP4 or a pixelated GIF, Lottie animations are mathematical descriptions of motion - paths, shapes, transforms, and timing - rendered live by the browser or app at runtime. The result is animation that stays infinitely sharp, scales to any resolution, and weighs a fraction of equivalent video.
The format was designed to close a specific gap. Motion designers produce stunning work in After Effects, but exporting it to the web has historically meant compromising on quality (GIF), file size (video), or interactivity (image sequences). Lottie solves all three. The Bodymovin plugin exports After Effects compositions directly to JSON, and a lightweight runtime renders them in any modern environment - web, iOS, Android, React Native, Flutter, or Unity.
The gap between a static interface and one that feels genuinely crafted is almost always motion. Loading states, micro-interactions, illustration hero animations, onboarding flows, success confirmations, empty states, scroll-triggered narratives - each becomes an opportunity to communicate brand quality and reduce perceived wait time. Appsrow designs and implements those animations: custom Lottie files built for your brand, optimised for performance, and integrated cleanly into your existing codebase or website.
We have built Lottie animations across SaaS product UIs, marketing websites, mobile apps, onboarding flows, e-learning platforms, and marketing campaigns - each with a different motion language, performance budget, and integration target. The consistent finding is that Lottie unlocks animation quality and performance simultaneously, which video and GIF formats cannot do.
The result is a product or website with motion that is fast, crisp, interactive, and lightweight - rendered in real time from a single small JSON file rather than a heavy media asset.

Why Lottie
The Real Cost of Shipping Without Proper Motion
Without proper animation, interfaces feel static and dated. GIFs are blurry and heavy. Videos are bloated and inflexible. Lottie removes every one of those compromises - giving you motion that performs, scales, and adapts.
Dramatically Smaller File Sizes
A typical Lottie file weighs 10-50KB - compared to 1-5MB for the equivalent GIF or 500KB-2MB for the equivalent compressed video. That means animations load instantly, even on slow mobile connections, and have a fraction of the impact on your site's Core Web Vitals scores.
Infinite Resolution and Crisp Edges
Because Lottie animations are vector-based, they render perfectly at any size - from a 16px favicon to a full-screen 4K hero. GIFs pixelate. Videos compress. Lottie stays mathematically sharp on every device, every resolution, every screen density, with no quality loss.
True Interactivity
Lottie animations can be controlled programmatically - paused, played, reversed, sped up, scrubbed to a specific frame, or driven by scroll position and user input. This unlocks scroll-based storytelling, hover micro-interactions, and animations that respond to application state in ways GIFs and videos cannot.
Dynamic Theming at Runtime
Lottie animations can have their colours changed at runtime through code, which means a single animation file can serve both light and dark modes, multiple brand variants, or user-customised colour schemes. No need to ship separate assets for every theme variation.
Cross-Platform With One Source
A single Lottie JSON file plays identically on the web, iOS, Android, React Native, and Flutter. Design once in After Effects, export once via Bodymovin, deploy everywhere. No need to recreate animations for each platform or maintain platform-specific motion assets.
GPU-Accelerated Performance
Modern Lottie players leverage the browser's hardware acceleration to render animations on the GPU. This keeps your main thread free for interactivity, prevents janky scrolling, and ensures smooth 60fps playback even when multiple animations run simultaneously on the same page.
Accessible and SEO-Friendly
Unlike GIFs and videos, Lottie animations do not block initial page render and do not negatively impact Largest Contentful Paint scores when implemented correctly. They can also be paused for users with reduced-motion preferences enabled - making your site both faster and more accessible.
Brand Consistency Across Touchpoints
Because the same Lottie file plays everywhere, your brand's motion language stays identical across your marketing site, mobile app, product UI, and email previews. Motion becomes a consistent brand asset rather than something that looks different on every platform.
Designer-Developer Workflow That Works
Motion designers create animations in After Effects using familiar tools and techniques. Developers receive a JSON file they can drop directly into their codebase. No back-and-forth iterations on video exports, no manual recreation in CSS, no compromise between design intent and engineering implementation.
"Lottie is the most practical path from a designed animation to a shipped animation. You keep the fidelity of After Effects and gain the performance and interactivity of native code without rebuilding the motion from scratch in every platform."
"The difference between an interface that feels modern and one that feels dated is rarely the visual design - it is the motion. Lottie is the fastest and most maintainable way to add high-quality animation, when it is implemented correctly from the start."
Our Services
Everything You Need to Ship Lottie Animations
Appsrow delivers end-to-end Lottie animation services - from a single optimised loading spinner to a complete motion system designed around your brand and integrated across web, mobile, and product UI.
01
Custom Lottie Animation Design
Original animation design built from scratch in After Effects to match your brand and product. Covers concept, storyboarding, character and shape design, timing, easing, and final export to optimised Lottie JSON. Suitable for hero animations, onboarding sequences, illustration sets, and bespoke brand motion.
02
After Effects to Lottie Conversion
Convert existing After Effects compositions into clean, optimised Lottie files. We audit your AE project for unsupported features, rebuild incompatible elements (mesh warps, certain effects, blending modes), and export via Bodymovin with the right settings to keep file sizes minimal and rendering performance maximal.
03
Lottie Performance Optimisation
Audit and optimise existing Lottie files for file size, render performance, and CPU/GPU efficiency. Common improvements include simplifying paths, reducing keyframe count, removing hidden layers, converting raster assets to vectors, and switching to dotLottie format - typically cutting file sizes by 40-80% with no visual change.
04
Webflow Lottie Integration
Embed Lottie animations into Webflow sites using Webflow's native Lottie element or custom code embeds for advanced control. Covers responsive sizing, scroll-trigger configuration, autoplay and loop settings, interactivity setup, and performance-conscious loading patterns that do not slow your site down.
05
React and Next.js Integration
Implement Lottie animations in React, Next.js, and Vue applications using lottie-react, lottie-web, or the official dotLottie React player. Covers SSR-safe loading patterns, lazy loading, animation state management, scroll-trigger hooks, and integration with state libraries and animation orchestration tools.
06
iOS, Android, and Flutter Integration
Embed Lottie animations into native and cross-platform mobile applications using lottie-ios, lottie-android, and the official Flutter Lottie package. Covers asset bundling, programmatic playback control, dynamic property updates, and platform-specific performance optimisation for smooth playback at 60fps.
07
Interactive and Scroll-Triggered Animations
Build animations that respond to user behaviour - playing on scroll position, reversing on hover-out, scrubbing through frames as the user moves, or transitioning between states based on application logic. Covers GSAP integration, ScrollTrigger setup, Intersection Observer patterns, and frame-perfect control.
08
dotLottie Conversion and Bundling
Migrate from legacy .json Lottie files to the modern dotLottie format. Benefits include built-in compression (typically 30-50% smaller), the ability to bundle multiple animations and assets into a single file, theme support, and improved player compatibility across modern frameworks and platforms.
09
Dynamic Theming and Colour Control
Implement runtime colour changes on Lottie animations so a single file serves multiple themes - light mode, dark mode, brand variants, or user-customisable schemes. Covers lottie-web property modification, dotLottie theme tokens, and integration with your application's theming system or CSS variables.
10
Accessibility and Reduced Motion Support
Implement prefers-reduced-motion media query handling so animations gracefully pause or skip for users with motion sensitivity. Covers ARIA labelling, fallback static assets for accessibility, and configurable playback speeds and intensity controls - making your motion both delightful and respectful.
11

Includes new animations on demand, performance audits on existing assets, player SDK updates as Lottie releases new versions, and priority delivery turnaround for marketing campaigns, product launches, and seasonal updates.
Why Appsrow
Why Appsrow Is the Expert Choice for Lottie Animation
We have spent years building at the intersection of motion design and frontend engineering. Our team understands both After Effects and the Lottie runtime at a technical level - and the precise constraints that govern what renders well in production.
Motion Design and Engineering Specialists
Our team has deep, hands-on expertise across After Effects, Bodymovin, dotLottie, and every major Lottie player runtime - lottie-web, lottie-react, lottie-ios, lottie-android, and Flutter. This is not general motion design applied to Lottie; it is platform-specific expertise across the full design-to-deployment pipeline.
Zero Performance Compromise
We integrate Lottie animations into your site or app without slowing page loads, blocking the main thread, or breaking your Core Web Vitals. Every animation is benchmarked for render cost, file size, and frame rate on real devices before delivery. Your performance budgets stay protected throughout the engagement.
Performance-First Implementation
File size and frame rate are not optional metrics - they are the difference between an animation that delights users and one that frustrates them on mobile. We optimise every Lottie file aggressively as a core deliverable, not an afterthought. Every layer, path, and keyframe is justified by its visual impact.
Concept Validation Before Full Build
For complex hero animations, scroll narratives, or character-driven motion, we deliver a motion prototype - a low-fidelity working animation - before full production begins. You see and approve the motion, timing, and interactivity in your real environment before we invest in final polish.
After Effects Expertise That Translates
Not every After Effects technique exports cleanly to Lottie. Mesh warps, certain effects, and blending modes do not survive the conversion. We design within Lottie's supported feature set from the start - not discovering compatibility issues at export time - which keeps timelines predictable and quality high.
File Size and Render Cost Optimisation
Bloated Lottie files compound page weight and burn mobile battery. We build animations that render efficiently - simplifying paths, reducing unnecessary keyframes, removing hidden layers, and using dotLottie compression where appropriate to keep both file size and CPU cost low in production.
Cross-Platform Delivery That Works
We choose the right player and integration pattern for each target platform - Webflow's native element, lottie-react for React apps, lottie-ios for native iOS, dotLottie for modern multi-theme setups - based on what is most reliable and maintainable for your specific stack, not what is fastest to ship.
Mobile Performance Auditing
Animations that look smooth on a developer's Mac can stutter on a three-year-old Android. We test every Lottie file on real low-powered devices, profile render cost, and recommend simplifications or alternatives if performance falls short. Your animations stay smooth on the hardware your users actually own.
Transparent Communication
You get a single point of contact, weekly progress updates, and a shared project tracker throughout every engagement. No hand-offs between teams, no waiting days for a status update, and no surprise scope changes after the project begins.
Documentation Your Team Can Use
Every animation ships with clear, maintained documentation written for your team - not your developer. Includes player configuration notes, supported interaction events, themeable property references, and a maintenance guide so internal staff can swap or update animations with confidence.
Cross-Industry Track Record
We have delivered Lottie animations for SaaS products, fintech apps, e-learning platforms, marketplace websites, mobile games, and consumer brands. Proven motion patterns from each sector inform every new project rather than starting from scratch on visual language and pacing.
Honest Scoping and Pricing
Fixed-fee scoping after the brief review, with no hourly billing surprises. If we discover something mid-project that changes scope - an unsupported AE feature, a new interaction requirement - we tell you immediately. You decide whether to expand the work or hold to the original plan.
Our Process
How We Deliver Your Lottie Animations
A structured, transparent process that keeps your brand intact, your performance budget protected, and your team informed at every stage - from the first brief through to post-launch monitoring.
01
Discovery
Brand and Motion Requirements Review
We start by reviewing your brand guidelines, existing visual language, target platforms, and the specific moments in your product or website where motion is needed. This includes looking at any existing animations, your performance budgets, accessibility commitments, and how Lottie will integrate with your current stack. The output is an accurate brief covering what needs to be animated, why, and how it should feel.
02
Strategy
Motion Direction and Storyboarding
We define the motion language for the project: timing, easing curves, weight, personality, and pacing. For larger projects, we produce storyboards or motion sketches that establish the visual approach before any After Effects work begins. You receive a clear motion direction document and timeline before production starts, with milestones, deliverables, and expected outcomes laid out explicitly.
03
Proof of Concept
Animation Prototype and Concept Validation
For complex animations or motion systems, we build a low-fidelity working prototype - a draft animation rendered as a real Lottie file in your real environment - so you can experience the motion in context before we invest in final polish. You confirm the timing, pacing, and interactivity feel right before full production begins, eliminating costly revisions later.
04
Build and Test
Animation Production and Export
Our motion designers produce the animation in After Effects with precise attention to Lottie's supported feature set, performance constraints, and your target platform requirements. Every shape, path, and keyframe is built to export cleanly. We export via Bodymovin or dotLottie tooling, validate the output across browsers and devices, and test render performance on real mobile hardware before delivery.
05
Stakeholder Review
Pre-Integration Client Walkthrough and Sign-Off
Before integration, we run a full walkthrough of every animation with your team. You see every loop, every interaction state, every edge case at full quality in a hosted preview. Any final adjustments to timing, colours, easing, or interaction behaviour are made here - so the integration phase is purely technical, with no last-minute creative changes blocking the engineering work.
06
Deployment
Integration and Team Handover
We integrate the animations into your live site or app using the right player and pattern for your stack - Webflow's native element, lottie-react, lottie-ios, dotLottie, or another runtime. Our team monitors the integration through the first real user sessions, resolves any edge cases that emerge in production, and provides complete documentation and training so your team understands how to manage and swap animations going forward.
07
Support
Ongoing Monitoring and Optimisation
Post-launch, we monitor animation performance metrics, Core Web Vitals impact, render frame rates on real devices, and player SDK version compatibility. When Lottie releases new player versions, dotLottie ships new features, or your product evolves, we adapt the animation library proactively. We also review performance data with you at regular intervals and recommend optimisations as your library grows.
08
Iterate
Quarterly Animation Reviews and Roadmap
Every quarter, we review animation performance, brand consistency, and emerging motion requirements with your team. New product areas, expanded marketing campaigns, new platform targets, or evolving brand direction - each becomes a planned iteration on your motion system rather than an unplanned creative scramble. Your motion library grows alongside your product, not behind it.
FAQ
Frequently Asked Questions
Everything you need to know about Lottie animation with Appsrow.
Lottie is an open-source animation format created by Airbnb that stores animations as JSON data describing vector paths, shapes, and motion - rather than as pixel data like GIF or compressed frames like video. A lightweight runtime renders the animation live in the browser or app at any resolution. This means Lottie files are typically 80-95% smaller than the equivalent GIF, stay infinitely sharp at any size, support full interactivity, and can have colours changed at runtime - none of which is possible with GIF or video formats.
No - provided the animations are optimised and integrated correctly. Appsrow delivers Lottie files that are typically under 50KB, render on the GPU, and load asynchronously without blocking your initial page render. We benchmark every animation against Core Web Vitals scores and test performance on real mobile devices. In most cases, replacing existing GIFs or videos with Lottie files actually improves site performance because Lottie's file sizes are dramatically smaller.
Yes - Webflow has a native Lottie element that supports drag-and-drop integration of JSON files, autoplay and loop settings, scroll-trigger configuration, and interaction triggers. For more advanced control - dynamic theming, runtime property changes, or custom interactivity - we add Lottie via custom code embeds using the official lottie-web or dotLottie players. Either approach works cleanly inside Webflow without affecting your Designer system or CMS structure.
Yes. Interactivity is one of Lottie's most powerful capabilities. We build animations that play on scroll position, reverse on hover-out, scrub frame-by-frame as the user moves, or transition between named segments based on application state. Common patterns include scroll-driven hero animations, hover micro-interactions on buttons and icons, click-triggered success confirmations, and onboarding sequences that advance with user input. Implementation uses Lottie's playback API directly or integrates with libraries like GSAP ScrollTrigger.
Yes - and this is one of the strongest reasons to use Lottie over video or GIF. Using the lottie-web or dotLottie player API, individual layer colours can be modified after the animation is loaded, which means a single file can serve light mode, dark mode, brand variants, or user-customised colour schemes. The modern dotLottie format also supports built-in theme tokens, making theme swaps even simpler. We design animations with theming in mind from the start so colour changes look intentional, not accidental.
Simple loading spinners, icon animations, and micro-interactions can typically be delivered within two to five business days. Hero animations, character-driven motion, and onboarding sequences usually take one to three weeks depending on complexity. Full animation libraries - 10 to 30 animations designed as a coherent system - typically take four to eight weeks. We provide a precise timeline after our initial brief review, based on your specific scope, target platforms, and existing brand assets.
Yes - and this is a common starting point. We audit your After Effects project for any features that do not export cleanly to Lottie (mesh warps, certain effects, specific blending modes, raster-based elements), rebuild incompatible sections using Lottie-supported techniques, and export via Bodymovin or dotLottie tooling with optimised settings. The result is a file that renders identically to your AE preview but at a fraction of the size of the equivalent video export.
dotLottie is a modern container format for Lottie animations - a ZIP-compressed file with the .lottie extension that can include the animation JSON, image assets, theme definitions, and even multiple animations in a single file. Compared to plain JSON, dotLottie files are typically 30-50% smaller, support built-in theming, and load faster across modern players. For new projects we default to dotLottie; for existing setups we migrate when the bandwidth or theming benefits justify the player swap.
Yes - cross-platform compatibility is one of Lottie's core strengths. A single Lottie JSON or dotLottie file plays identically on the web (lottie-web, lottie-react), iOS (lottie-ios), Android (lottie-android), React Native, and Flutter. The same animation file you ship on your marketing site can be reused in your mobile app without re-design or re-export, ensuring brand consistency across every touchpoint and reducing the long-term maintenance cost of your motion library.
Yes - this is a situation we handle regularly. Existing Lottie files often have oversized file sizes (raster assets that should be vectors, excessive keyframes, unused layers), render performance issues (too many simultaneous masks or expressions), or playback bugs caused by unsupported AE features. We audit your existing animations, identify what is causing the problem, and either optimise the current files or rebuild them cleanly depending on what is more practical and cost-effective for your situation.
They can be, when implemented correctly. We add prefers-reduced-motion media query handling so animations gracefully pause, simplify, or skip for users who have enabled motion sensitivity settings on their device. We also provide ARIA labelling for screen readers, fallback static images for non-rendering contexts, and configurable playback intensity where appropriate. Accessibility is part of every Lottie delivery, not a separate workstream.
The Lottie ecosystem releases player updates regularly across web, iOS, Android, and Flutter. With our maintenance retainer, we monitor release notes from LottieFiles and the open-source maintainers, test your animations against new SDK versions ahead of deprecation deadlines, and update player integration code as needed. Without a retainer, we still notify past clients of breaking changes affecting their setup and offer fixed-fee remediation work when updates require code changes.
Book a free Lottie animation brief review. Our team will review your brand, your existing motion (if any), your target platforms, your performance budgets, and the specific moments in your product where animation is needed. We will then give you a no-obligation animation roadmap - the recommended motion direction, a realistic timeline, and a clear investment figure. There is no commitment required for the review, and you will leave the call with actionable clarity on exactly what could be built and how - regardless of whether you choose to work with us.
