Open Source

You're working on a frontend. Claude is helping.
Meanwhile, another Claude is working on the backend in a different terminal.

They have no idea the other exists.

AI Agents That
Talk to Each Other

With Clauder, your Claude instances communicate. The frontend Claude asks the backend Claude: "What's the API contract?" and gets an answer. No copy-pasting. No being the messenger between your own AI agents.

curl -sSL https://raw.githubusercontent.com/MaorBril/clauder/main/install.sh | sh

Then run clauder setup to configure your tools.
