“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 | Julep | Laddr | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 6.8 | Laddr — Pick it for genuinely parallel work across several specialists; pick Temporal if what you actually need is durable workflows with retries. |
| El Crítico | 5.8 | 6.3 | Laddr — Agents call tools you write in Python and no shell tool ships in the box, so the distance from pip install to working system is measured in your afternoons. |
| El Profesor | 6.8 | 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 | 6.0 | 6.0 | no preference |
| La Jefa | 6.3 | 5.0 | Julep — Costs nothing for sixty engineers and drops straight into existing CI, but no single sign-on, audit trail or support channel is documented anywhere. |
| El Hacker | 7.3 | 7.0 | Julep — Apache-2.0 Python I can read end to end, MCP tools arriving over a protocol instead of plugins, and a CLI that deploys flows, but no local model path. |
