A way to track versions of ALL software and notify users about new version.

Started with a niche and launched it: VersionAlert for Unity (https://versionalert.com/unity)

Working on the bigger product still. Existing solutions I've found in this space seemed lacking. On my website, I want people to quickly find the software they want to be kept up to date about (with a smart search bar that does the heavy lifting for them) and easily sign up for notifications for new versions. Hope to make a Show HN for it soon!
