Pterocos - Free online editor now supports C# (plus Rust, Python, Ruby, SQL, Lua)

Hey Indie Hackers 👋

I built Pterocos (https://pterocos.eu.org) - a free online editor that runs entirely in your browser. No installation, no account required.

Just added: C# support! 🚀

What Pterocos now supports:

- C# (NEW!)

- Rust 🦀

- Python 🐍

- Ruby 💎

- SQL (SQLite and DuckDB)

- Lua

- HTML/CSS/JS

What makes it different:

- Runs entirely client-side (your code never leaves your browser)

- No tracking, no analytics, free forever

- Persistent storage via localStorage

- Perfect for learning, quick prototyping, and sharing examples

Try it: https://pterocos.eu.org

Would love honest feedback from the IH community! What languages or features would make this more useful for your workflow?

What you suggest me to add also to the editor :]

Thanks for checking it out.
