AI Agent Framework
Summary
Pi Durable is an experimental harness from Earendil for building long-running, crash-resilient agentic applications on any JavaScript runtime. It supports infinitely long conversations, multi-user steering, and pluggable storage with abstracted execution environments.
Highlights
- Ships alongside Pi 1.0 as an experimental package, not a replacement for the Pi coding agent
- Designed to survive catastrophic internal and external failures via checkpointed tasks
- Supports multiple humans steering the same agents simultaneously with forked threads
- Abstracts execution environments so tools can run on a laptop, remote VM, or in-memory sandbox
- Built on principles of minimalism and malleability shared with the Pi coding agent

Source Overview
Pi Durable is an experimental harness from Earendil for building long-running, crash-resilient agentic applications on any JavaScript runtime.
It recovers from process deaths via checkpointed tasks, uses pluggable storage backends (memory, SQLite, JSONL), and abstracts execution environments for cross-machine tool calls. One harness instance runs multiple concurrent conversations, including forked threads, without blocking.
