Introducing Pi 1.0 for Rivet

Running agents inside the sandbox is simple in theory

But in production, the sandbox's blast radius becomes your agent's blast radius:

💥 Sandbox OOMs → agent dies
🔑 Credentials → need a proxy
💤 Sandbox asleep → no crons
🔄 Update → redeploy every VM

Now with Rivet, you can run the vanilla Pi harness in your backend, separated from the sandbox

The sandbox can crash, sleep, or fill its disk. Your agent keeps running

Built for background & multiplayer agents

S3 is the only dependency in Rivet 3.0 (coming soon)

It's architected for easy self-hosting and embedding in your own apps

But that also meant getting rid of NATS.... https://t.co/l7334blnrR
