Open source ≠ free to use
Projects like BrowserOS are free to install but expect you to supply API keys—costs add up fast when Agent runs multi-step tasks.

The free trap
Why "free agentic browser" searches feel misleading
Freemium caps Agent depth
Comet, Fellou, and Dia limit credits or waitlists. You get chat on a page, not a browser that executes workflows end-to-end.
Lists don't help you decide
Most "best agentic browser" articles rank ten tools without a clear free winner or a one-click download for real Agent execution.
