A remote browser: does such a thing exist?

Right, and for those of us who prefer building our own setups — I’ve been doing this for automation projects — there’s also the self-hosted route. You can set up Headless Chrome or a Selenium Grid on your own servers to run a remote browser. You control it via HTTP APIs or WebSockets, and while it takes a bit more setup, you get full control and scalability. Great for test automation, debugging, or even secure browsing setups. Plus, you’re not locked into third-party ecosystems.
