Hi .NET community,

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

What it supports:

• C# (.NET via Mono)
• Rust
• Python
• Ruby
• SQL (SQLite and DuckDB)
• Lua

Why it's useful for .NET developers:

• Quickly test C# snippets without opening Visual Studio
• Prototype algorithms on any device
• Share runnable examples in documentation or with learners

The editor runs entirely client-side - your code never leaves your browser.

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

Would love feedback from the .NET community!
