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.
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.

@heyitsirenechan Thanks Irene, glad you found it easy to get around.
Country filtering is available, but not on the public pages. It is a paid feature that lets you filter by country, technology, product type, launch type and date range.
We also don't just guess the country from the site’s IP address. We use information the company publishes on its own legal pages, along with tech affinity signals. Each exported row includes a confidence score, so you can decide how strict you want to be.

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?
StackScope
@yelyzaveta_kibets Our search box does the first bit. Paste in a competitor’s URL and, if we’ve analysed it, their stack will come back.
We catch sites as they first go live rather than continuously monitoring them. The nearest thing we offer is 'Stackdar', which watches for a technology rather than a particular site. Name the analytics tool and you'll get an alert whenever a new launch ships with it.

@datafreak Right, so the shape is per-technology not per-site. That flips it into an adoption tracker, which is a different job than the one I had in mind.
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?
StackScope
@richatsealedvault just checked - your browser triggered our scraping protection. It's constantly changing it's user agent and switching between different parameters which triggered Cloudflare.
@datafreak Glad I could share that with you as some new visitors may encounter the same issue. Congratulations on your launch and honestly when everything works smoothly. I think it's a cool tool to use especially before Makers launch, precheck tool is definitely a must.
I assume that it finds only products or sites that have completed a launch. As I did a search on StackScope, it returned empty.
StackScope
@richatsealedvault Haha, fair!! It is in there, I excluded our own site from our own index back in April when I was testing!
@datafreak Got it. Do individuals also get the same privilege to be excluded? Hahaha :-)
StackScope
@richatsealedvault Absolutely, we offer a self service removal path.

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.
@datafreak Hello Jonathan, I was curious about what StackScope could find and do. I tried your own site and nothing showed up. Then I was checking your launch readiness tool and all of sudden, I was blocked from accessing your site. I wonder why and what could the reason for the blocking??
StackScope
@richatsealedvault I will send you a message on Twitter with more detail.
@datafreak cool! thanks and I wish you the best of launch wishes!
Barely started and my site is already on stackscope, cool!
I can definitely see myself losing an unreasonable amount of time browsing through this just to see techtacks. Really interesting dataset to have access to. Congrats on getting this out there! @datafreak

@zach_francis Thank you Zach!
