“Renamed from Claude Flow to Ruflo, which the author says stands for Rust, flow states and inevitability; one of those is a language.”

“It is built on Tauri, React, Rust, Monaco and xterm, which is five technologies stacked up to avoid opening a terminal.”

Which one would each critic pick
| Critic | Ruflo | Sinew | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.0 | 5.8 | Ruflo — Pick Ruflo if you already live in Claude Code and want a hundred specialised agents behind one MCP command; pick oh-my-claudecode if you want a pipeline you can explain. |
| El Crítico | 4.8 | 5.3 | Sinew — One sign-in route uses provider OAuth flows reserved for first-party clients, and the project's own documentation records the risk of doing that. |
| El Profesor | 4.8 | 6.0 | Sinew — The agent's visible surface is whatever the operator leaves enabled, and system prompts are injected from two named repository files rather than assembled invisibly. |
| La Inversora | 4.8 | 4.3 | Ruflo — One author, MIT, 70,000 stars, two hosted UIs at flo.ruv.io and goal.ruv.io with no price on either; a talent asset, not a company. |
| La Jefa | 4.0 | 4.3 | Sinew — Free across sixty desktops, and because each install is reshaped by the developer who runs it, no two of my engineers would be using the same agent. |
| El Hacker | 7.3 | 6.0 | Ruflo — MIT, 27 hooks, Ollama and OpenRouter in the router, an MCP server I start with one npx command, and enough source to lose a month in. |
