Pi Durable | Earendil
Pi Durable is a new experimental package for long-running, durable, and malleable agents that can run anywhere. A tour of what we built and why.
Sample implementation of the pi-durable harness hosted in a Cloudflare Durable Object, providing a React-based chat app with multiplayer sessions, conversation forking, scheduled follow-ups, and subagent transcript search.
Requires Node.js 22.19+, pnpm 11, and an OpenAI API key for local development. Deploys to Cloudflare Workers via Wrangler; the code intentionally omits authentication and rate limiting.
