Tech Stack Detector

What does Tech Stack Detector do?

Tech Stack Detector identifies 100+ technologies running on any website — CMS, analytics platforms, CDN providers, JavaScript frameworks, payment processors, chat widgets, and more — plus generates Go-To-Market (GTM) signals like estimated monthly tech spend, company stage, and buying signals.

Built on the Apify platform, results are returned in seconds and integrate with Apify's scheduling, webhooks, and 1,500+ tools.

FAQ & Support

Is this legal? Technology detection reads publicly loaded JavaScript, HTML, and HTTP headers — the same signals any browser observes when loading a page.

Known limitations: Server-side technologies (databases, backend frameworks) that leave no client-side footprint cannot be detected.
