Open Managed Agents
Open-source Claude Managed Agents alternative — self-host on Cloudflare or Docker
Open Managed Agents is a solid open-source pick if you're comfortable with Cloudflare or Docker and want to own the agent runtime. Drop-in API compatibility makes migration painless, and the per-store adapter design is thoughtful. But it's early-stage—docs are thin and you'll carry the ops load. For zero-maintenance, stick with the proprietary Claude Managed Agents service. If you need full control and data ownership, OpenMA is worth the effort.

Skip Open Managed Agents if you want a managed, zero-ops solution with no infrastructure maintenance, or if you're not comfortable with Cloudflare Workers and Docker.
Self-hosting is free, but you'll spend time on infrastructure setup and maintenance—Cloudflare Workers, Durable Objects, and Docker all have learning curves.
OpenMA's self-hosted tier is permanently free—no per-seat or usage fees—which beats proprietary alternatives like Claude Managed Agents that charge per token or seat. The hosted service is metered only on sandbox compute, with BYOK covering LLM costs, making it cheaper for light use than many SaaS agent platforms. However, enterprise support is absent; for guaranteed uptime, consider managed services.

About Open Managed Agents
Open Managed Agents (OpenMA) is an open-source, wire-compatible replacement for the Claude Managed Agents API. It replicates the same /v1/agents and /v1/sessions endpoints and SSE event stream, so existing client code can migrate by swapping the base URL. You control the runtime and the data, whether you deploy to Cloudflare Workers + Durable Objects + Containers + R2 with a single wrangler deploy, or run the Docker container with Node + Postgres + S3 on your own VPS. This makes it a practical choice for developers who want to own their agent stack and avoid vendor lock-in. The platform follows a meta-harness design: you write the brain (reading events, building context, calling the model) while OpenMA manages the sandbox, event log, tools, and crash recovery. That separation lets you customize context engineering, caching, or compaction without touching the platform layer. Durable sessions with strong consistency run on Durable Objects with embedded SQLite, each agent step executes in a real Linux sandbox via Cloudflare Containers, and workspace snapshots are stored in R2. For non-Cloudflare environments, a backend abstraction layer offers per-store adapters—D1 or Postgres for state, S3 for blobs—and pluggable sandbox runtimes like LocalSubprocess, LiteBox, E2B, Daytona, and BoxRun. Everything is Apache 2.0 licensed, so you can fork it, embed it in your product, or run a private fleet with no per-seat fee and no usage tax. Self-hosting is free forever; when you bring your own API key (BYOK), there's no token markup. If you'd rather not run infrastructure, the hosted service at openma.dev is the same codebase, charging only for sandbox compute. OpenMA is not a plug-and-play SaaS—you'll need to operate Cloudflare or Docker. But the five-line Docker quickstart spins up a local stack fast, and recent guides cover self-hosting a Claude Tag-style agent and migrating from the proprietary service. For developers who want to own the agent runtime and avoid vendor lock-in, OpenMA offers a solid path.
Behind the Verdict
Open Managed Agents is a genuinely useful open-source alternative for developers who want to own their AI agent stack without being locked into a vendor's runtime. The drop-in compatibility with the Claude Managed Agents API is the standout feature—you can keep your existing client code and simply swap the base URL, which lowers the migration barrier considerably. The architecture is thoughtful: Durable Objects with SQLite give you consistent, long-lived sessions; Cloudflare Containers provide real Linux sandboxes; and R2 stores workspace snapshots. The meta-harness design is a differentiator—you write the event loop, and the platform handles the infrastructure. That's a powerful separation for teams that want to customize context engineering or caching. The backend abstraction layer is another plus: you can mix and match stores (D1 or Postgres) and sandbox runtimes (LocalSubprocess, E2B, Daytona, etc.) without touching the core. Self-hosting is free and Apache 2.0 means you can fork and embed it. The hosted service is metered only on sandbox compute, which is fair for BYOK usage. However, this is not for everyone. You need real infrastructure know-how: deploying Cloudflare Workers, understanding Durable Objects, or running Docker with Postgres and S3. The documentation is thin and the project is early-stage, so there's no guarantee of stability or security hardening. There are no uptime SLAs and no official support. If you're a non-technical user or a team that wants a plug-and-play SaaS, stick with the managed Claude Agents service. But for developers who value control and data ownership, OpenMA is a compelling choice.

Real-world workflow fit
Concrete scenarios for the personas Open Managed Agents actually fits — and what changes day-one when you adopt it.
Migrate an existing Claude Managed Agents client to OpenMA self-hosted
Outcome: Swap the base URL in your client code to http://localhost:8787 (or your deployed endpoint) and run the same /v1/agents and /v1/sessions calls—existing code works unchanged, and you gain full control over the runtime and data.
Deploy OpenMA to Cloudflare for a data-compliant internal agent
Outcome: Use wrangler deploy to spin up Workers, Durable Objects, Containers, and R2—one command brings up the whole platform, giving you a scalable, compliant agent runtime without managing servers.
Build a custom agent loop with a different harness
Outcome: Replace the default harness with your own context engineering and tool-delivery logic, while OpenMA handles sandboxing, event log, and crash recovery—so you can experiment with new agent patterns without reinventing infrastructure.
Use Cases
- Replace Claude Managed Agents with a self-hosted alternative while keeping existing client code unchanged.
- Build and deploy custom AI agent workflows with full control over the event loop and sandbox environment.
- Run sandboxed code execution sessions that persist across requests using Durable Objects.
- Host internal MCP servers and Claude Code skills without external dependencies.
- Develop and test agent harness modifications locally with Docker Compose before deploying to Cloudflare.
- Migrate a fleet of Claude Tag-style agents to an open-source, self-hosted platform.
Models Under the Hood
as of 2026-08-19
Limitations
- The platform requires significant infrastructure knowledge to deploy and operate.
- The hosted service offers no uptime SLA or official support.
- Documentation is thin and the project is early-stage, so you may encounter rough edges.
- Sandboxed code execution may be subject to Cloudflare Container constraints, limiting resource-intensive workloads.
- There is no drag-and-drop UI; everything is API/CLI and code-first.

Setup time & first value
How long it actually takes to get something useful out of Open Managed Agents — broken out by persona, not the marketing-page minute.
For a developer, the Docker quickstart can get a local instance running in under 10 minutes (five-line setup). For Cloudflare deployment, expect 30–60 minutes to configure wrangler and deploy. For a custom non-Cloudflare setup with Postgres and S3, plan for a few hours to set up the databases and environment.
Switching to or from Open Managed Agents
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Claude Managed Agents: swap the base URL in your client code to point to your OpenMA instance; the API is wire-compatible, so no code changes are needed.
- ↗To Claude Managed Agents: switch the base URL back to the managed service; your custom harness code may not port directly, but the API surface is identical.
