   2. RunbookHermes

   The agent runs multi-signal diagnosis across observability data, builds a root-cause hypothesis, and generates or updates runbooks from what it learns — so the next incident with the same failure pattern starts from a documented baseline instead of a blank slate. The approval-gated remediation workflow means automated action doesn't ship without a reviewer, which matters when the blast radius is a production service. Where it breaks: the repo is five commits deep with zero open issues, which signals early-stage software, not battle-hardened infrastructure. Teams with complex multi-service topologies will hit integration gaps before the agent's reasoning does. Self-hosting is required, so operationalizing this adds a deployment and maintenance surface your platform team owns.

   3. Memharness

   The core premise is storing facts, not strings, with two independent time axes: when something became true in the world and when the agent learned it — so querying past agent states is a real query, not archaeology through logs. Everything lives in a single SQLite file, which means the storage layer makes zero LLM or network calls and stays auditable. Recall combines hybrid vector search and full-text search with a source-staleness signal, so older or superseded sources rank down automatically. Where it breaks: the SQLite backend is a hard ceiling for teams expecting distributed writes or high-concurrency production deployments. Teams hitting that ceiling will need to treat memharness as a pattern to port, not a service to scale horizontally.

   4. BrAIn

   Built on NATS as its messaging backbone, brAIn distributes agent nodes across hardware and wires them together through a reactive event bus — so an agent fires when something happens, not when a scheduler decides it should. Each node can carry its own UI, which means you monitor individual agents in context rather than reading logs and guessing. The architecture is documented (ARCHITECTURE.md, AGENTS.md), MIT-licensed, and ships with Docker and a monorepo package structure, so self-hosting is the intended path. The project is early-stage with 3 stars and 282 commits from a solo maintainer, which means production hardening and community support are things you contribute rather than consume.
