HookBus^®

The AgentHook-aligned runtime router.

HookBus is the open agent event bus. Apache 2.0, free, self-host. Carries AgentHook-compatible lifecycle events from AI agents and coding assistants to subscribers for policy, audit, cost tracking, evidence recording, and anything else you plug in. Vendor-neutral. Open-source publishers exist for Claude Code, OpenAI Codex CLI, Amp, OpenCode, Hermes and OpenClaw, and any HTTP-capable runtime can post events.

• Apache 2.0, free for any organisation to self-host.
• Routes events to subscribers: policy, audit, cost, evidence recording.
• Implements the AgentHook evidence standard.
• Runs in Docker. On-prem, VPC, or air-gap.
