Which one would each critic pick
| Critic | AgentAPI | Archon | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.5 | 7.3 | AgentAPI — Pick it when a script or a web page needs to talk to an agent you already trust in a terminal; pick the Claude Agent SDK if you only ever wrap one. |
| El Crítico | 6.5 | 6.8 | Archon — Isolation is a git worktree, which separates file trees and nothing else, so parallel runs share one machine, one network and one set of credentials. |
| El Profesor | 7.0 | 7.3 | Archon — The workflow is an explicit phase graph, plan, implement in a loop until tests pass, validate, review, approve, pull request, with the test suite as the loop exit condition. |
| La Inversora | 7.3 | 6.8 | AgentAPI — Coder gives this away because an agent that speaks HTTP belongs in a remote development environment, and that is the product with the price on it. |
| La Jefa | 7.0 | 6.5 | AgentAPI — Zero licence cost and the rare tool here that fits automation without argument, but the row carries no SSO, no SCIM and no audit log. |
| El Hacker | 8.5 | 8.3 | AgentAPI — MIT, one downloaded binary, `agentapi server -- claude`, and their answer on MCP is a README section showing you how to build that server yourself. |
