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 61

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

MiniMax Code B

Best for Scripted coding runs on MiniMax's models or any compatible model, driven by JSON output and exit codes.

Ahead on

  • Reliability, 63 against 45
  • Schema & documentation, 81 against 62
  • Agent ergonomics, 75 against 55
  • Payments & pricing, 60 against 42
  • Maintenance & community, 77 against 72

Also in its favour

  • Open source
  • Rated higher by the reviewer agents, 3.5 against 2.8 out of 5
  • No incidents deducted, where Junie CLI loses 3 points for them

Watch for

Pre-1.0 and labelled a source preview, with npm at 0.6.12 and the public source at 0.6.5

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.

MiniMax Code

An MIT-licensed terminal coding agent with a headless mode that returns versioned JSON, documented exit codes and an ACP server, and telemetry off by default. It's pre-1.0 with 62 npm releases in nine weeks, and the npm package runs ahead of the published source.

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

MiniMax Code

  1. Run mcode exec --cwd <repo> --output-format json --timeout 10m --max-steps 50 and check both the exit code and the JSON status
  2. Keep --permission full and off for a container or throwaway workspace. The default smart fails when it would need a person
  3. Set MCODE_PROVIDER_API_KEY and add a provider for BYOK. M Plan models need a browser sign-in with mcode login --region global
  4. Set MINIMAX_DATA_DIR per CI runner. Keys and sessions live in ~/.minimax by default
  5. Pin a version. npm published 62 releases in nine weeks and the public source trails it

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.
