Which one would each critic pick
| Critic | OpenCode | pi | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 8.0 | 7.5 | OpenCode — OpenCode is what to hand anyone who wants the Claude Code shape with their own keys and a model picker; pick Claude Code if you want one vendor and one bill. |
| El Crítico | 7.0 | 6.8 | OpenCode — Commands run with your permissions and no sandbox, and the Zen gateway offers free models without saying who pays for them. |
| El Profesor | 6.8 | 7.3 | pi — A unified LLM API, an agent loop, a TUI and a CLI in one monorepo; sessions branch into a tree with compaction that summarises abandoned branches; no benchmark is published. |
| La Inversora | 6.0 | 5.5 | OpenCode — Two hundred thousand stars is distribution, the Zen gateway is the business model, and a company that renamed itself mid-flight is a company still deciding what it is. |
| La Jefa | 5.8 | 5.5 | OpenCode — Free and MIT is the easy line; sixty engineers each holding a provider key with no SSO, no audit log and no vendor is the hard one. |
| El Hacker | 8.8 | 8.5 | OpenCode — MIT, Ollama for offline, MCP servers in opencode.json with a published $schema, custom agents, and it has already been forked, which is the point. |
