Production AI governance, in your stack's language.

Inline policy enforcement, decision records, and governed step execution — for Python, TypeScript, Go, Java, and Rust. Same APIs as the platform; thin wrappers over REST. Source-available under BSL 1.1.

Five SDKs, one API surface

All SDKs are thin wrappers over the same REST APIs. Pick the language you ship in — or use the HTTP API directly for languages without an SDK.

Three execution modes

Same SDK, three integration shapes depending on how much of the request lifecycle you want AxonFlow to manage.

Gateway Mode

Request-boundary governance for existing stacks. Pre-check → your call → audit. Best when you want to keep your current LLM-call code path and just bolt policy on top.

Proxy Mode

Full request lifecycle: policy, planning, routing, audit. AxonFlow proxies model and tool execution end-to-end. Recommended for new projects where you control the call site.

WCP Mode

Workflow Control Plane — governed multi-step execution with step gates, durable ledger, cancellation, and SSE streaming. Drop in alongside any orchestrator (LangGraph, CrewAI, custom).

Self-hosted Community is free.

Run AxonFlow on your own infrastructure with the SDKs above — no license required. Outgrow Community? Get a free Evaluation license for elevated limits, HITL approvals, and policy simulation. Production at scale? Move to Enterprise for full org-wide policies, advanced compliance frameworks, and SSO/SCIM identity integration.

Building IDE/agent tooling instead of integrating SDKs? See our plugins for Claude Code, Cursor, Codex, and OpenClaw.
