6 Top Wappalyzer alternatives (free and paid)

When researching competitors or just getting inspiration for a website stack, Wappalyzer is one name that often comes up.
Wappalyzer is a well-known tool that lets you identify the technologies and frameworks a website uses.
However, accessing Wappalyzer’s full range of features comes at a cost! You get 50 website lookups monthly for free, but after that, it costs $250 per month for 5,000 lookups.
That can be a significant expense for small businesses or individual users, so seeking alternatives might be the best option.
This article lists some free and paid Wappalyzer alternatives for you to try.
