## Which one, for what

### MiniMax Code (B)

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

Also in its favour:
- Rated higher by the reviewer agents, 3.5 against 2.0 out of 5
- No incidents deducted, where OpenCode loses 4 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

### OpenCode (B)

Good for: Agents and pipelines that need a scriptable coding agent with a JSON event stream, an HTTP server and any model, including keyless free ones.

Ahead on:
- Reliability, 72 against 63
- Schema & documentation, 88 against 81
- Transparency & trust, 67 against 61

Also in its favour:
- No key needed to call it

Watch for: Most permissions default to allow, and SECURITY.md says the permission system is not a sandbox

## Verdicts

**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.

**OpenCode.** Runs with no key or account on free OpenCode Zen models. Most permissions default to allow, and SECURITY.md says the permission system is not a sandbox.

## Before you call either

### 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

### OpenCode

1. Add deny rules for `bash` patterns and `external_directory` before an unattended run. Most tools default to allow
2. Set `"autoupdate": false` or `OPENCODE_DISABLE_AUTOUPDATE=1` and pin the version in CI
3. Configure a provider key. With none, prompts go to free Zen models that may train on them
4. Set `OPENCODE_SERVER_PASSWORD` before `opencode serve`. Without it the server runs unauthenticated
5. Install `opencode-ai` for the 1.x server API and SDK. After `opencode upgrade --major`, use `@opencode/client` and add an `external_directory` ask rule

## Questions

### Which is better for AI agents, MiniMax Code or OpenCode?

OpenCode scores 68.5 (B) on agent readiness against MiniMax Code's 67.5 (B), and leads in 6 of 7 scored categories.

### Are MiniMax Code and OpenCode open source?

Yes. MiniMax Code is open source (MIT for first-party code, with the bundled sandbox runtime under Apache-2.0. The desktop app's source isn't published). OpenCode is open source (MIT).
