Which one would each critic pick
| Critic | Oh My Coder | OpenHarness | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 6.0 | Oh My Coder — Pick Oh My Coder if the tools everyone recommends are unreachable from where you work; pick Claude Code the moment they are not, and the project documents that move for you. |
| El Crítico | 5.5 | 5.5 | no preference |
| El Profesor | 5.5 | 6.0 | OpenHarness — The project ships its own evaluation suite, which is more than most of this board attempts, and publishes no results from running it. |
| La Inversora | 5.5 | 4.5 | Oh My Coder — 187 stars, a permissive licence and no company. The only moat is geographic, and a moat made of somebody else's unavailability is not a moat you control. |
| La Jefa | 4.8 | 5.3 | OpenHarness — Free across sixty desks, and an official Python SDK driving the same binary from pipelines is the part that would let me measure it rather than hear about it. |
| El Hacker | 6.5 | 7.0 | OpenHarness — MIT, it finds a running Ollama on its own and starts with no API key at all, and MCP servers attach, which is close to my ideal first five minutes. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
