Replit Animation: Vibe-Code Animated Videos with Gemini

Replit Launches Animation: Build Videos with Code and AI

Replit introduced Animation, a new tool that allows developers to create animated videos entirely within the Replit platform. Rather than requiring dedicated video editing software or specialized motion graphics skills, Animation enables users to describe what they want in natural language and have the Agent handle the technical implementation — writing TypeScript using modern animation libraries to construct scenes, manage timing, and export the result as a standard MP4 file.

How It Works

Under the hood, Animation translates natural language instructions into code. The Agent writes TypeScript that orchestrates animation logic — handling keyframes, easing functions, and scene composition — and combines this with generated images or video clips. The result is a fully code-driven animation pipeline that lives inside a Replit project and can be modified iteratively through chat.

A dedicated "Animation Lab" interface provides a real-time preview, allowing developers to scrub through timelines and fine-tune their animations before export. The feature also integrates with Replit's 3D Website Builder, enabling animation of Three.js scenes and WebGL shaders.

Powered by Gemini

Animation is powered by Google's Gemini model, continuing the Replit–Google partnership that has brought a range of Gemini capabilities — including multimodal reasoning and code generation — into the Replit platform.

Who This Is For

The feature is targeted squarely at the vibe coding audience: developers who build at the intersection of creative output and code. Rather than exporting assets from separate tools, Animation allows the full video production workflow — design, motion, rendering — to happen inside Replit projects.
