I looked at a few similar tools and projects online. Many of them felt either too limited, while using a full video editor was just too much work for what I wanted to achieve.
So I decided to build something I would actually use: paste some code, choose a theme and animation, adjust the speed, and export.
It started as a very simple typing animation tool. I then added line-by-line playback, GIF export, long PNG screenshots, themes, window styles, and a few other things.
Everything runs in the browser, and your code isn't uploaded to a server for processing.
I'm curious whether character-by-character or line-by-line playback is actually useful for real development tutorials, and what other use cases I might be missing.
