Pterocos – browser-based code editor with Kotlin/Wasm support (feedback welcome!)

WebAssembly
1

Hello Kotlin community,

I’m excited to share Pterocos – a free, open-source code editor that runs entirely in your browser via WebAssembly, and now supports Kotlin!

What it does:

  • :purple_circle: Kotlin support – write and run Kotlin code directly in your browser using Kotlin/Wasm, no installation needed

  • :globe_with_meridians: Built on Monaco Editor (the engine behind VS Code)

  • :robot: Integrated AI assistant for debugging and code suggestions

  • :package: Multi-language support: Kotlin, Python, Ruby, Rust, C#, PHP, Java, Lua, SQL (SQLite & DuckDB), and more

  • :locked: Privacy-first: your code stays in your browser’s local storage by default

  • :globe_showing_europe_africa: Optional sharing: publish projects publicly and get feedback from the community

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

GitHub: GitHub - aminkheddache-dotcom/Pterocos: A Place to build, test and code in html css and js. · GitHub

Why I’m sharing this with you:
This is a brand-new tool, and feedback from experienced Kotlin developers like you matters a lot. I want to make sure the Kotlin/Wasm experience is solid – from syntax highlighting to code execution. Your input would be invaluable in shaping the future of this tool.

Some specific questions for the Kotlin community:

  • What Kotlin features would you expect from a browser-based editor?

  • Are there any Kotlin/Wasm-specific workflows you’d like to see?

  • Does the current WebAssembly runtime feel fast enough for your needs?

I’d love to hear your thoughts, feature requests, or even bug reports. Thank you for taking the time to check it out!

Best regards,
Amine khd
