About

There are a lot of browsers, and they receive updates at an alarming rate. It isn’t always easy to find full and comprehensive changelogs or get them directly into your feed reader.

If you’re working on legacy systems with older browsers, it can be an effort to track down all the old changelogs and note what is different. Particularly in the case of very old or obscure browsers, changelogs can have never been written, the sites hosting changelogs can have gone down, or (in the case of very early browsers) they were only published physically.

Browser.Observer provides you with changelogs directly or otherwise points you in the direction of where you can find them. It comes complete with screenshots of browsers at that version and details about browser engines too.

Browser.Observer is built with the Web Origami dialect of JavaScript and served entirely statically via Cloudflare. The type in use is the versatile and adaptable Recursive, for both body and headings.
