*Key insight:* - Extension = limited (no accessibility tree, weaker context) - Browser + Playwright = full power (HTML tree, real-time DOM, automation)

I was going to open-source the extension (MIT) to get traction/contributors. But now: *90% of future value is in the browser + agent*, not the extension.

*Dilemma:* - OSS extension → community grows shell, but I lose control of the real product - Keep all closed → slower feedback, harder to validate

*Options:* 1. *Source-available extension* (public code, no forks/commercial use) 2. *OSS only the extension SDK* (API to plug into Vibe Browser) 3. *Stay fully closed*, launch browser beta first

LangFuse: MIT core + paid EE Raycast: closed core, open extensions

*HN:* - Should I OSS the weak part (extension) to build mindshare? - Or keep everything closed until browser MVP ships? - How to get early users without giving away the moat?
