Wappalyzer alternative: Sitegeist
Looking for a Wappalyzer alternative? Wappalyzer is the best-known technology profiler on the web, and its free extension remains good at answering "what is this site built with." The common reasons people go looking elsewhere: the project went closed source in 2023 after a decade of community contributions, and its hosted products are priced for lead-generation teams, with plans that start in the hundreds of dollars per month as of this writing.
Sitegeist answers a wider question about a narrower scope: not just what one site is built with, but how it is designed. One click returns the tech stack alongside the full design system: color palette with usage counts, type scale, real button styles with states, spacing, assets, SEO checks, and tone of voice. Everything runs locally with no account and no lookup quota.

FAQ
Is Sitegeist a free alternative to Wappalyzer?
For checking what a single page is built with, yes. Sitegeist detects common frameworks, CMSs, hosting, and analytics locally in your browser with no account, and pairs that with a full design-system teardown. It does not offer bulk lookups or lead lists.
Does Sitegeist send the pages I inspect to a server like Wappalyzer?
No. Sitegeist analyzes the page locally using the activeTab permission with on-demand injection. Nothing you inspect leaves your browser, and there is no account or lookup quota.
What does Wappalyzer detect that Sitegeist does not?
Wappalyzer maintains a very large technology fingerprint database and, as of this writing, sells hosted products for bulk lookups, lead generation, and market research. If you need breadth across thousands of technologies or company data at scale, Wappalyzer's paid products cover ground Sitegeist does not try to.
Why do people look for Wappalyzer alternatives?
Two recurring reasons in public discussions: the project moved from open source to closed source in 2023, and the hosted plans are priced for sales teams as of this writing. Casual users who just want to peek at a stack often want something lighter.
