Project mention: Show HN: I built a bare minimum live coding editor | news.ycombinator.com | 2024-12-31
There are many editors for coding interviews. However, when I started looking for one, they all came bloated with features I didn't need: compilers, code completion, prepackaged exercises, and now AI assistants. So, I built one. It has two features: collaborative editing and code highlighting — nothing more.
The source code is open and available on GitHub: https://github.com/marnikitta/livecoding
