Supervisor — a runtime for production LLM agents

A two-tier planner/executor architecture for agentic systems, with first-class plans, replay, and step-level observability.

Stack
TypeScript / Node.js / Postgres / Anthropic API

A small framework for building agentic systems where the plan is an artifact, not an emergent property of the model's attention. Powers two internal products and one customer-facing one. Open-sourcing the core in the second half of 2026.
