Show HN: LocalAgent v0.5.0, a local-first Rust agent runtime

CalvinBuild Sunday, March 15, 2026

LocalAgent is a local-first agent runtime in Rust focused on tool calling, trust and approval gates, replayable runs, and benchmark-gated coding workflows.

A lot of the recent v0.5.0 work was about hardening coding-task behavior, improving validation and completion behavior, and reducing the ways evals can be gamed.

One thing that stood out during that work was OmniCoder-9B Q8_0. I care less about “looks good in a demo” and more about whether a small model still holds up under real repo tasks, explicit validation, replayable runs, and stricter task contracts without relying on benchmark-specific hacks.

OmniCoder-9B Q8_0 is one of the few small local models that has felt genuinely solid in that environment for me. I am not making a broad “best model” claim, but it stayed on track better under constraints that usually expose weak reasoning, fake progress, or contamination.

Curious if others doing real local coding workflows have seen similar results with OmniCoder or other small models.

Summary
LocalAgent is an open-source decentralized platform that enables secure communication and data sharing between individuals and organizations, without relying on centralized servers or third-party services.
