README
¶
Microbus is the only fabric where every agentic workflow runs on a true microservice substrate. That single design choice gives your workflows security, scale, observability and prompt-driven authoring that bolt-on workflow engines cannot match.
Documentation
Full documentation lives at docs.microbus.io, including:
- Get Started — bootstrap a project, take the agent-guided tour, build your first workflow or microservice.
- Agentic Workflows — multi-step processes with branching, fan-out, human-in-the-loop interrupts, and durable state.
- Agentic RAD — how coding agents drive Microbus development end to end.
- Microservice Substrate — the production-grade fabric the workflows run on.
- Security in Depth — the layered security model.
- Package Reference — every package's role and exported API.
- Release Notes — per-release changes.
Quick Start
You'll need a coding agent (e.g. Claude Code), Go 1.26+, NATS, and a SQL database for agentic workflow state. Then:
mkdir -p myproject
cd myproject
Ask your coding agent to bootstrap Microbus:
curl the workflow at microbus.io/bootstrap and follow it
The agent walks through the bootstrap, sets up .claude/ rules and skills, scaffolds the project, and verifies the build. See Get Started for the full walkthrough.

Overview ¶
Package fabric is the module root of the Microbus framework. It declares no public API of its own; the framework is consumed through its subpackages such as connector, service, application, and httpx. This file exists so the module root resolves to a buildable package for tooling that lists it.
