“It ships a playground, because the only way to know what six delegating agents will do is to sit and watch them do it.”

Which one would each critic pick
| Critic | CrewAI | Laddr | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.0 | 6.8 | CrewAI — Pick CrewAI if you think in roles and want a working multi-agent crew before dinner; pick LangGraph when you need to control every step and resume after a crash. |
| El Crítico | 6.3 | 6.3 | no preference |
| El Profesor | 6.3 | 7.0 | Laddr — Every agent action is recorded to SQLite or PostgreSQL with optional Langfuse spans, which makes the execution trace an artefact rather than a log line. |
| La Inversora | 6.5 | 6.0 | CrewAI — Used by 65% of the Fortune 500 is the claim, a 45-day onboarding is the offer, and forward-deployed engineers a la carte is the business: a services company with a popular library on top. |
| La Jefa | 6.0 | 5.0 | CrewAI — As a dependency it is free for sixty engineers, the hosted Basic tier's 50 executions a month is a rounding error for us, and SSO, RBAC and PII redaction live in an unpriced Enterprise tier. |
| El Hacker | 7.5 | 7.0 | CrewAI — MIT, uv tool install crewai, MCPServerAdapter in crewai_tools with streamable-http, and LiteLLM underneath so my Ollama box is a first-class provider; the hosted platform is optional. |
