Live manim, with the animation you are editing already on screen

Checkpoints at every play(), hot reload that replays only what changed, and scenes rendered by your own GPU.

Install it

ManimLive runs your scenes, your packages and your files, so it runs on your computer. Nothing on this page connects to it.

python -m pip install --upgrade --force-reinstall --no-cache-dir "maniml @ git+https://github.com/tayweid/maniml.git"

Open it

Starts the engine and opens the app at http://localhost:8685, where it offers to install as a desktop app with its own icon and window. That offer belongs to the local app, not to this page, so only one ManimLive ever owns your Python files.

maniml app ~/Projects

What you get

Checkpoints at every play(). Step forward through your animations, re-running each from source, or jump back instantly.
Hot reload that replays only what changed. Save the file and the edited animations replay from the last good checkpoint.
Click a mobject to find it. It prints the variable name; drag it and you get a paste-ready move_to([x, y, z]).
Bake a scene to share. --export writes a self-contained page students can scrub through, with no Python anywhere.

Alpha software, built from 3Blue1Brown's ManimGL lineage with code adapted from ManimCommunity's Manim. Not an official ManimCommunity project. Source on GitHub.
