Tools and Web apps

Miscellaneous tools and small web apps to solve random problems. Mostly pretty prototypey and low-polish but, hey, sometimes you just need function rather than form.

Compare Lists. Sometimes I need to quickly get a union, intersection, or diff between some lists, and be able to easily copy them in a ready-to-use format. This little tool helps with that.
Input Detector. Sometimes I'm not sure what the browser will detect as a mouse/keyboard input, so having something to display it can be handy.
Clipboard Content Display. I'm often writing custom paste-handling for stuff copied from other applications, so being able to see what they put into the clipboard (including every MIME-type) is super useful.
Page Preview Generator. Used by this site to create social images for each page on this site, via Playwright. No real use case outside of that.
