💡 No servers, no proxies, no hacks
— just clean, secure, cross-domain tab control.
Browser security is strict — and rightly so. But this extension uses the extension layer as a bridge, letting developers control tabs securely and simply using postMessage. It respects boundaries, enforces domain filtering, and fits cleanly into modern web architectures.
I built it to be robust, cross-browser, and dead simple to integrate. No fluff, no overengineering.
If you're a developer who loves tools that "just work" — this one’s for you.
