I had just released https://versiondb.io a few hours ago. It's something where you're able to get a slice of what's running on the web without breaking the bank. The full version contains over 4M domains and over 3K detected technologies.

Have fun and I hope you guys find it useful.

Is there data on what site search engine they use? This is hard to get as it is sitting deep in the backend but will be super useful information. built with doesn’t have this, but they do have a list mapping search engine (Bloomreach, Coveo, Algolia) to the website probably based on private data dumps. Being able to look this up for a website will be very useful.
