Best agent harnesses and coding agents · All 226 harnesses comparisons

Which one, for what

Muse Code C

Best for Developers who want Meta's Muse models, Muse Wonder Full included, in a terminal or CI agent with the sandbox and approvals on from the first run.

Also in its favour

  • No incidents deducted, where OpenHands loses 5 points for them

Watch for

Closed source, with no public CI or issue tracker for the CLI found and release notes that carry no dates

OpenHands BB

Best for Teams that want to self-host a coding agent with a web UI, per-conversation Docker sandboxes and scheduled or webhook automations, or embed the agent through a Python SDK and REST API.

Ahead on

  • Reliability, 83 against 45
  • Payments & pricing, 60 against 20
  • Maintenance & community, 85 against 75
  • Transparency & trust, 67 against 57

Also in its favour

  • Agent-ready, a grade of BB or better
  • Open source

Watch for

Confirmation mode is off by default in Agent Canvas, and the npm install gives the agent the host's whole filesystem

Verdicts

Muse Code

Muse Code runs with approvals and an OS sandbox on by default, per-host network approval, an append-only event log and a headless mode with documented exit codes. It is the only route to Muse Wonder Full. It is closed source with undated release notes and no free route, and subscriptions allow training on code unless Contributor mode is turned off.

OpenHands

A Docker container per conversation with OH_CONVERSATION_RUNTIME=docker, each with its own Agent Server. Confirmation mode is off by default in Agent Canvas, and the npm install gives the agent the host's whole filesystem.

Before you call either

Muse Code

  1. Set META_API_KEY for headless runs. Browser sign-in isn't available in CI or for Meta Managed Accounts
  2. Gate on your own test command, not the exit code. muse exec returns 0 when the turn completes even if tests still fail
  3. Pass --max-model-steps on unattended runs so a stuck task can't loop
  4. Prefer --disable-approval to --yolo in CI so the sandbox stays on. On Linux the runner needs a working bubblewrap and a non-musl build
  5. Turn Contributor mode off in /settings before a subscription session touches private code

OpenHands

  1. Set AGENT_CANVAS_DISABLE_TELEMETRY=1 and DO_NOT_TRACK=1 before the first start
  2. Start Canvas with OH_CONVERSATION_RUNTIME=docker or use the Docker image. The npm install runs the agent on the host
  3. Turn on confirmation mode with a risk threshold. Canvas starts with it off
  4. Use the SDK or the Agent Server API for headless runs. The openhands --headless CLI is no longer maintained
  5. Set filter_tools_regex on the agent to keep unneeded MCP tool definitions out of the context
