“The desktop app talks straight to the ObjC runtime rather than ship Electron, which is a grudge with a build system.”

“Builds for macOS and Linux only, so Windows developers get to keep the startup time this was written to complain about.”

Which one would each critic pick
| Critic | graff | pi_agent_rust | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 6.5 | no preference |
| El Crítico | 6.0 | 5.8 | graff — The sign-in promise rests on subscriptions the documentation never enumerates, so nobody can tell before installing whether the plan they already pay for is one of them. |
| El Profesor | 6.8 | 5.8 | graff — Annotate mode pins a page element into the next message with its role, accessible name and selector, which is a structured reference rather than a screenshot. |
| La Inversora | 5.3 | 5.5 | pi_agent_rust — One author, 1,706 stars since a February 2026 first release, and the product is a reimplementation of somebody else's agent, which is enthusiasm rather than a position. |
| La Jefa | 5.3 | 5.3 | no preference |
| El Hacker | 6.3 | 7.5 | pi_agent_rust — Custom providers are declared in models.json, Ollama, llama-server and mistral.rs are supported by name, and the licence is MIT with an OpenAI and Anthropic rider. |
