“Runs on your own Ollama from the CLI, but the plugin still wants a JetBrains AI credit, of which the free plan gives you three.”

| Browser control | YesThe Playwright MCP server is enabled by default for the cloud agent and code review, so it drives a real browser rather than only searching the web. | NoNo built-in browser or Playwright tool in either the CLI or the IDE plugin; web automation only arrives through a user-added MCP server. |

Which one would each critic pick
| Critic | GitHub Copilot | Junie | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.8 | 7.0 | GitHub Copilot — Not the strongest agent here and the easiest to start with; if your code already lives on GitHub, begin here and add a stronger tool where it falls short. |
| El Crítico | 6.5 | 6.3 | GitHub Copilot — The isolation is real but remote: the sandboxed cloud agent is the part you pay premium requests for, while local agent mode runs on your machine outside it. |
| El Profesor | 5.8 | 7.0 | Junie — Junie's SWE-rebench first place is a rolling-set result that moves run to run by the organizer's own account, and its debugger integration is a verification channel most agents on this board lack. |
| La Inversora | 9.3 | 8.0 | GitHub Copilot — Incumbency is the moat: inside the editor, inside the repository host, on invoices approved years ago, with Microsoft's balance sheet behind it. |
| La Jefa | 8.0 | 7.5 | GitHub Copilot — Already on the invoice, with the IP indemnity and policy controls legal asked for on Business and Enterprise; the premium-request meter needs an org-level cap. |
| El Hacker | 4.8 | 6.0 | Junie — The CLI takes my own keys, OpenRouter, Ollama or LM Studio, and an mcpServers block; the plugin is closed and wants a JetBrains AI credit, of which the free plan gives three. |
