OpenFang
A Rust 'Agent Operating System' that runs scheduled autonomous agents from a single binary.
OpenFang is an open-source Agent Operating System written in Rust and shipped as a single binary of about 32MB with a local dashboard. Its core concept is 'Hands': pre-built autonomous capability packages (manifest, system prompt, SKILL.md and guardrails such as approval gates) that run on schedules without prompting, e.g. Researcher and Lead. The site lists a WASM tool sandbox, Ed25519 manifest signing, a Merkle audit trail, SQLite plus vector memory, 40 channel adapters, and MCP and A2A support. The README marks it pre-1.0 (v0.5.10, April 2026) and warns of breaking changes.
