Compare
One index of how Open Managed Agents compares with vendor-managed runtimes, open-source runtimes, SDKs, and coding agents. Each entry names the category and links to the detailed comparison.
Hosted runtimes that run sessions and the agent loop on the vendor's platform. OpenMA keeps this resource shape and lets you run it yourself.
Vendor-managed runtime (Claude)
Anthropic's hosted runtime. It supports self-hosted sandboxes, but the harness and sessions run on Anthropic.
Vendor-managed runtime (OpenAI)
OpenAI's hosted agent runtime, separate from the open-source Agents SDK.
Harness as a service (Moonshot)
Moonshot AI's hosted agents, described as harness as a service and running on Kimi models.
Hosted product (Anthropic)
Anthropic's hosted product; it is not open source. OpenMA is a foundation for building a Claude Tag-style agent you run yourself.
Projects in the same category as OpenMA: runtimes whose control plane you can run on your own infrastructure.
Open-source managed agent runtimes
Compared by agent resources, durable sessions, sandboxes, vaults, and deployment options.
Open orchestration runtime on Kubernetes
Compared with OpenMA and vendor runtimes on sessions, sandboxes, model routing, and durability.
Different categories that are often compared with OpenMA. SDKs run the loop inside your process; coding agents are tools developers drive. OpenMA can run Claude Code, Codex, and other agents as harnesses through ACP adapters.
Agent SDK (library)
A library for the agent loop inside your own process.
Open-source coding agents
Software-engineering agents, comparable to Claude Code and Codex.
Autonomous coding agent
An autonomous coding agent product. A detailed comparison with OpenMA is not published yet.
Cloud coding agents (Cursor)
Cursor's cloud agents product. A detailed comparison with OpenMA is not published yet.
OpenMA is an open-source, self-hostable alternative to Claude Managed Agents and OpenAI Agents API. It handles sessions, execution, and recovery, so you can run agents with any model, any harness, and any sandbox, on any cloud.
Use it hosted, or self-host on Node.js, Docker, Fly.io, Vercel (Beta), or Cloudflare under Apache-2.0. Read agent as a service for how the hosted and self-hosted options work.
Claude Managed Agents and the OpenAI Agents API. Both are vendor-managed agent runtimes; OpenMA exposes a Claude Managed Agents-compatible API and an OpenAI Agents API adapter, and runs hosted or on your own infrastructure.
No. OpenMA is a runtime that runs agents: sessions, sandboxes, tools, credentials, and recovery. Coding agents are a different category. OpenMA can run coding agents such as Claude Code and Codex as harnesses through ACP adapters.
Compare products within the same category, on the same primitives: sessions, sandboxes, model and credential routing, and durability. The AI agent platform page explains each one.
OpenMA, TrueForge, and Omnara are open-source managed agent runtimes you can self-host. See open-source managed agent runtimes compared.
