Description
Pi 1.0 is a coding agent harness from Earendil, built from months of community issues and pull requests, now stable enough for people and businesses to depend on. Alongside it, Earendil ships Pi Durable, an experimental substrate for long-running agentic apps reachable beyond the terminal. Both are MIT licensed.

Could you build this?
Partial A lightweight agent harness prototype can be vibe coded, but building a production-hardened, durable substrate capable of resilient long-running task execution, sandboxing, and fault recovery requires deep distributed systems engineering.
What it would actually take: A durable agent harness relies on an event-sourcing or temporal workflow engine (like Temporal, Inngest, or custom SQLite/PostgreSQL state machines) to snapshot and resume agent state across process restarts and network failures. The critical challenges include sandboxed code execution, managing context window compaction without state corruption, and ensuring strictly deterministic tool execution.
