Go Micro
Build agents, services, and workflows on one Go runtime.
Go Micro delivers on treating agents as services, with a pluggable runtime and durable workflows that checkpoint execution. The micro loop feature and OpenAI support make it a strong choice for Go teams building production agentic systems. However, the Go-only requirement and self-hosted model limit its appeal to broader audiences.
- Go developers building production-grade agent systems
- Teams needing durable workflows with agent orchestration
- Developers integrating services as AI-callable tools via MCP
- Engineers building multi-agent systems requiring A2A interop
- Non-Go developers (framework is Go-specific)
- Teams wanting a low-code/no-code agent builder
- Projects that need a managed cloud platform (self-hosted deployment model)

Field guide on agent frameworks; Go Micro's answer: an agent is a service, contrasting with LangChain, LangGraph, CrewAI, AutoGen, and tRPC-Agent-Go.
How Go Micro Builds Itself
Go Micro is built by an autonomous loop with Codex writing code and Claude Code orchestrating, human sets direction. Details loop mechanics and failures.
Go Micro is an Agent Harness
Go Micro positions as a harness for operating agent loops — tools, state, guardrails, recovery, observability — built on the stack teams already deploy.

Building a Support Agent in Go
Tutorial for building a support desk agent with Go Micro: ticket triggers an agent that looks up customer, sets priority, replies — with human-in-the-loop gate.
Agents Across Frameworks: A2A
Go Micro agents now speak Agent2Agent protocol; cards generated from registry, same as MCP gateway derives tools.
Bringing an Open Source Project Back from the Dead
Go Micro (started 2015, went quiet after VC-funded pivot) returns to v6 via agents, services, and flows.

About Go Micro
Go Micro is an open-source agent harness and service framework for Go that unifies agents, services, and durable workflows on the same runtime. It provides the production infrastructure agents need—model, memory, tools, planning, delegation, guardrails, and execution middleware—while treating every service endpoint as an AI-callable tool automatically via the Model Context Protocol (MCP) and enabling cross-framework agent communication through the Agent2Agent (A2A) protocol. Designed for Go developers building production-grade distributed systems, Go Micro lets you scaffold an agent or service with a single command (`micro new`), run it locally with hot reload, an API gateway, and an interactive console (`micro run`), or deploy to production with `micro build & deploy`. The framework is built on pluggable Go interfaces for registry, broker, transport, store, auth, caching, and storage, letting you swap components like Consul for mDNS or gRPC for HTTP without code changes. What makes Go Micro different is its "agent as a service" philosophy: an agent is a distributed system, and building one is building a service. Agents, services, and flows come from the same primitives, with durable workflows that checkpoint and resume mid-run. It also integrates x402 payments, enabling agents to settle stablecoin payments autonomously. Recent additions include `micro loop`, an autonomous loop for repository management driven by AI agents, and OpenAI Codex for Open Source support. Go Micro is Apache 2.0 licensed and self-hosted, contrasting with managed platforms like LangChain or Vercel AI SDK. It's ideal for teams that want full control, pluggability, and Go-native performance, but not for those seeking a no-code builder or managed cloud solution.
Behind the Verdict
Go Micro isn't another Python agent library. It's a Go framework that treats an agent as a distributed service — with discovery, RPC, events, state, and auth baked in. If you're a Go developer building production-grade agent systems, this is one of the most coherent options out there. The standout feature is the pluggable architecture. Every component — registry, broker, transport, store — is a Go interface. You can swap mDNS for Consul or HTTP for gRPC with a single config change. That's rare in agent frameworks, which often lock you into their defaults. Durable workflows are another win: they checkpoint and resume mid-run, so long-running agent tasks survive restarts. The recent introduction of micro loop is a big step. It drops an AI-driven autonomous loop into any GitHub repo, with planner, builder, triage, coherence, and release pipeline agents. Combined with OpenAI Codex for Open Source support, Go Micro is increasingly eating its own dogfood — the framework itself is built by AI agents. Where it bites: Go only. If your team isn't in Go, this isn't for you. There's no low-code builder, no managed cloud — you run it yourself. Documentation is solid but community size is smaller than LangChain's. The x402 payment integration is innovative but still niche. Compared to LangChain, Go Micro is heavier on infrastructure and lighter on pre-built agent chains. For Go teams wanting control and performance, it's a better fit. For rapid prototyping or non-Go stacks, pass. In practice, we'd reach for Go Micro when building a multi-agent system that needs reliable service discovery, event-driven activation, and cross-framework interop via A2A. It's a solid backbone for production agentics.

Use Cases
- Build a support agent that triages tickets, looks up customer data, and replies with human-in-the-loop approval
- Create a durable order processing workflow that resumes after partial failures without re-executing completed steps
- Expose existing Go microservices as MCP tools for use by any AI agent
- Set up a multi-agent system where agents discover and call each other via the A2A protocol across frameworks
- Deploy an agent that autonomously manages a GitHub repo with planning, code generation, and CI pipeline triggered by events
- Integrate x402 payments into an agent so it can autonomously pay for third-party API usage or services
Limitations
- Go Micro is a Go-only framework, so non-Go developers cannot use it directly.
- It is self-hosted with no managed cloud offering, requiring DevOps overhead for deployment and scaling.
- The agent harness currently lacks built-in support for multimodal models or non-Go runtimes in workflows.
- As an open-source project, production support is community-based or via sponsors, not a vendor SLA.
