Best agent harnesses and coding agents · All 713 harnesses comparisons

Which one, for what

Junie CLI D

Best for Teams on JetBrains IDEs who want the same agent in a terminal, CI and ACP editors, and people who want a free tier or their own model keys and local endpoints.

Ahead on

  • Transparency & trust, 78 against 67

Also in its favour

  • Free to start without a card

Watch for

One-shot, piped, ACP and Gateway runs trust the project by design and load its MCP servers, hooks, agents and skills without a prompt

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
  • Schema & documentation, 87 against 62
  • Agent ergonomics, 78 against 55
  • Security & auth, 66 against 56
  • Payments & pricing, 60 against 42
  • Maintenance & community, 85 against 72

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

Junie CLI

Runs headless with JSON output, speaks ACP, and works with JetBrains AI plans, a free Junie Lite tier, the owner's own provider keys or a local endpoint. Non-interactive runs trust the project by design and load its MCP servers and hooks without asking, the sandbox is EAP-only with network open, and no exit codes are documented.

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

Junie CLI

  1. Run headless only in repositories you trust. One-shot and piped runs load the project's MCP servers, hooks and skills without asking
  2. Set JUNIE_API_KEY (from junie.jetbrains.com/cli) or a provider key such as JUNIE_ANTHROPIC_API_KEY in CI. The default sign-in opens a browser
  3. Add --output-format json or --json-output-file to parse results. Check the output, since exit codes aren't documented
  4. Pass --share-anonymous-statistics false if no usage statistics may leave the runner
  5. Pin a build with --use-version and --skip-update-check. The CLI updates itself on start by default

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

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
