We designed SiteStacks for Firefox to be a lightweight tool to see the tech behind any URL/company. When activated, the extension opens the results in a new tab and runs the lookup on our own servers. No background processes are running and the user’s CPU is spared 🙏. While keeping the extension simple, there’s a relentless focus on increasing coverage (now tracking over 40,500 products) and accuracy (data from a number of lower-confidence methods has been hidden). Interested in a data partnership? The extension has seen some decent & consistent organic growth 📈 since quietly launching it a few weeks ago. We’re keeping the stats page public so you can follow yourself and track the impact of a Product Hunt launch. 🐱🚀 https://addons.mozilla.org/en-US...

Really useful, implementing this into my workflow. Thank you!

Any plans for a Chrome version? Ditched Firefox completely after they took it upon themselves to install advertising plugins without the users permission

It's as easy as you can see: just add an extension, and when you click on the icon you get a new tab listing the stack of that site. However, as the makers state, the database of stack still needs to grow to detect more things. It looks like in a few weeks / months will have this issue solved and this will be a rock-solid plugin.

Pros:

Really quick and lightweight way to know a site's stack

Cons:

Database still needs to grow

I'm Firefox-biased so I had to instantly try it when I saw it. You've a useful product here guys! Some random feedback / comments: 1) I don't know why, but I expected it to open the stack list in a little pop-up, like Google Tag Assistant does. Maybe it'd be more handy this way? 2) While the plugin is still useful and does its job, I felt like creating a plugin to just open a tab with an URL isn't a game changer. I could do a bookmarklet for achieving something similar. Maybe it'll be good to have something like I said in the point 1, or an integrated windows inside the same tab, so we have more useful functionality besides your website. 3) Builtwith.com is able to identify that my Wordpress site uses the Genesis framework. Just a heads-up for if you find interesting to add the Wordpress frameworks and themes to the database :) That's all. All in all, a good extension to have enabled! Let me know if you agree / disagree with any of my comments, always happy to discuss! :)
