Loong vs. OpenFang
Loong
OpenFang
A Rust-native foundation for vertical AI agents with an architecture-first, policy-authorized security model. Currently an early skeleton rewrite — promising design, but not yet a usable agent product.
A Rust-built 'Agent Operating System' shipping as a single ~32MB binary with autonomous scheduled agents ('Hands') instead of chat-driven prompts. Ambitious and heavily tested, but pre-1.0 with breaking changes and a release cadence that appears to have stalled since May 2026.
Verdict
OpenFang has the stronger current case.
Useful guidance with a reasonable evidence base behind it. AI decision layer last reviewed Oct 5, 2026. AI decision layer last reviewed Oct 5, 2026.
Choose Loong if
- you want to keep more of the workflow local or optional-cloud
- you specifically need rust developers building custom vertical ai agents
- you specifically need teams wanting a policy-first security architecture
Neither if
Nothing in the current evidence rules both of them out.
Choose OpenFang if
- you want faster setup and less operational overhead
- you want lower day-two risk and fewer hardening surprises
- you depend on integrations, skills, or extension headroom
