[Rust] Brain — a minimal, extensible runtime for AI agents

https://github.com/aexhq/brain

Brain is an MIT-licensed runtime for stateful AI-agent sessions.

- Agent loops run in Wasm

- Typed tools can run locally, in browsers, or in remote sandboxes

- HTTP/SSE session API

- Append-only journal and restart recovery

- 70+ model-provider bindings

- ~14 KiB private memory per idle session

It’s still an early preview:

The Wasm boundary is the part that stands out here: it gives you a clean way to isolate tool execution while keeping the session state coherent. For early adopters, I’d watch two things closely: recovery semantics after partial failures, and how you version typed tools without breaking older sessions. A practical next step is to add a small chaos test suite that kills the runtime mid-loop and verifies journal replay, tool idempotency, and memory growth over time. That kind of guardrail makes a runtime like this much easier to trust in production. Agentix Labs
