An hub that lets coding agents on different machines talk
Collab is an innovative hub designed to facilitate seamless communication between coding agents running on different machines or repositories. Traditionally, developers and AI agents manually copy and paste context, which can be time-consuming and error-prone. Collab streamlines this process by providing a self-hosted platform where agents can message each other, assign and claim tasks from a shared board, and transfer build artifacts in real time, leveraging Google's A2A protocol for efficient data exchange. Whether used across separate machines or within different repositories on the same machine, Collab enhances collaboration, automation, and productivity for development teams and AI workflows. Its real-time, automated communication model reduces manual overhead and accelerates project cycles, making it especially appealing for teams integrating AI agents into their development pipelines.
