Hello everyone,

I wanted to share a free tool I've been working on called Pterocos (
https://pterocos.eu.org) that might be of interest to the C++ community.

What it offers:

No setup required – Runs entirely in the browser via WebAssembly, with no
installation or account needed. Just open the link and start coding.

Powered by Monaco Editor – The same editor engine behind VS Code, providing
a familiar editing experience with syntax highlighting, autocompletion, and
intellisense.

C++ compiler integration – Compiles and runs C++ code client-side using
WebAssembly, making it ideal for quick prototyping and testing algorithms
without waiting for a local toolchain to set up.

AI assistant – Built-in AI capabilities for debugging assistance and code
generation, which can be helpful when exploring new concepts or tracking
down errors.

Technical background:

Pterocos is open-source and runs entirely client-side. The C++ support is
implemented using WebAssembly-based compilation, meaning all code execution
happens locally in the browser without sending code to any server – which
addresses privacy and security concerns.

I'd love to get feedback from the C++ community here. What features or
improvements would make this more valuable for your daily C++ workflow? Any
suggestions on compiler flags, standard library support, or integration
with common C++ tools would be greatly appreciated.

Looking forward to your thoughts.

Best regards,
