Restack helps companies treat AI agents like real product features. Product teams can version prompts and tools and build feedback loops, while data teams supply the right context for the agents to use.

Engineers, in turn, get an open-source stack that runs agents reliably at scale on Kubernetes. The code is available on GitHub, and there are docs to help you begin. It is aimed at organisations that need their agents to be dependable in production.
