See which sites started using Stripe, Shopify or Next.js this week. Most of what we index we find ourselves: over 2.2+ million sites from public infrastructure signals, not submitted to us, across 40,000+ technologies. When we reach a launch before the boards, we're 14.5 days early. Browsing is free. Paid plans add Stackdar alerts, API access, bulk export with published contact details, and an MCP server for Claude, ChatGPT and Cursor.
Wow! I am disappointed. I was checking out your product and site. Found precheck for launch interesting and then suddenly, I am blocked from accessing the site. Why is that?
I assume that it finds only products or sites that have completed a launch. As I did a search on StackScope, it returned empty.
Every time I want a competitor's stack I end up in view-source, squinting. Does it tell me when a site I already track swaps its analytics?
Tried it, and it's very interesting to see the site's tech stack. Very easy to browse and see the data!
My fave tech is those with Google Analytics and Google Search Console. The only thing is that I don't think I can filter by location. I found some interesting sites but realized the site is not in our target audience's usual location.
Hi all!
I'm Jonathan. I built StackScope on my own.
It started because I wanted to know what new sites are actually built with. BuiltWith and Wappalyzer are good at the established web, but by the time something shows up there it isn't new any more. I wanted the leading edge.
So most of what StackScope indexes, it finds itself. The discovery pipeline has turned up over 2.2 million sites from public infrastructure signals rather than waiting for anyone to submit them, and it identifies more than 40,000 technologies across them. When it reaches a site before the launch boards do, it gets there about two weeks earlier.
Over 420,000 of those are classed as startup launches. The rest is the ordinary new web, and you can narrow to either.
Browsing and searching are free. Paid plans add standing alerts when new sites pick up a technology, an API, CSV export with the contact details those sites publish, and an MCP server so you can query directly from Claude, ChatGPT or Cursor.
If you had one watch, what technology would you put it on? Genuinely useful for me to know.

Who hunted StackScope?
StackScope was hunted by Jonathan Howell. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
