We (GREP.AI, YC F26) are open-sourcing AgentRun and turning it into a full managed agents platform. Read more about it in this post: https://agentrun.ai/blog/introducing-agentrun-run-smarter-ag....

It includes what we originally built for our own agent harness:

- Self-improving agents - Web-grounded workflows - A range of sandboxes and computer environments - Thousands of tools and integrations - Detailed analytics on how your agents behave

You can bring your own agent. AgentRun works with Pi, Claude Agents, Codex, OpenCode, and any other harness that supports ACP.

You can self-host it (see 1-click install on Render) with an OpenRouter key, or try the hosted version at console.agentrun.ai.

We’d love feedback, especially on the architecture (see README), or anything we may be missing to make it useful to you.
