CSS animation

Follow along as a CSS keyframe animation is built from scratch, then export it as a Reel-ready video your design-curious audience will love.

From code to TikTok in three steps

Step 1

Add keyframes

Paste your code and add as many keyframes as you need. Each keyframe captures a snapshot of your code at a specific point in time.

Step 2

Preview transitions

CodeReels automatically computes the diff between consecutive keyframes and generates a smooth animated replay — no editing required.

Step 3

Export and share

Export your code story as an .mp4 or .gif ready to post as a TikTok, Instagram Reel, or YouTube Short — or drop it into a README or embed it in your documentation.

Everything you need to tell your code story

Code timeline

Build a sequence of code keyframes that capture the evolution of your implementation — perfect for short-form content that teaches one concept at a time.

Smart transitions

Animated diff replay between keyframes shows exactly what changed and when — creating the satisfying 'aha moment' that makes developer TikToks go viral.

One-click export

Export your code story as an .mp4 or .gif ready to share as a TikTok, Instagram Reel, YouTube Short, or embed in your documentation.
