Open Managed Agents: open-source alternative to Claude

About Open Managed Agents

Open Managed Agents (OpenMA) is an open-source platform for running AI agents under your own control. It reimplements the Claude Managed Agents API and also exposes the OpenAI Agents API, so existing clients and the official OpenAI SDK can point at it. Agents run with durable sessions, sandboxed tools, memory, encrypted credentials and crash recovery, and you bring your own model keys.

There are two ways to run it. The Node host uses SQLite or Postgres with local file storage and a choice of sandboxes such as LiteBox, Daytona, E2B or BoxRun, and starts with docker compose. The Cloudflare host runs on Workers, Durable Objects and Containers with D1, KV and R2, and deploys with wrangler. Both expose the Claude-compatible agents and sessions API, a console UI and the OpenAI-compatible endpoint, and support MCP, private tools and encrypted vaults.

OpenMA is written in TypeScript and licensed under Apache-2.0. A hosted version is available at app.openma.dev for teams that prefer not to operate it, while the self-hosted options suit on-premises or data-resident deployments. It targets teams that want an alternative to Claude's managed agent service while choosing their own models and infrastructure.
