From URL to intelligence in seconds
Paste any publicly accessible website URL into the scanner. No special access or permissions required.
TrueTechFinder analyses headers, scripts, markup, and network responses against 700+ technology fingerprints.
A 0–100 score is calculated based on the modernity, security posture, and overall health of the detected stack.
An AI-generated plain-English summary explains what the technology combination means and flags any risk signals.
The only free checker with a Health Score and AI insights
Every scan produces a 0–100 health rating. Most technology checkers show you raw lists. TrueTechFinder tells you whether those technologies are healthy, outdated, or carrying detectable risk.
The detected technologies are passed to an AI model that generates a narrative summary — explaining what the stack combination means, what kind of site it suggests, and what to watch for.
Compare any two websites and get a similarity score, technology overlap breakdown, and an AI-generated comparison narrative. No other free tool offers this combination.

TrueTechFinder achieves high accuracy on client-side and server-header technologies. Some technologies are intentionally obfuscated by their operators, and minification can sometimes obscure JavaScript framework signatures. The AI insight accounts for detection confidence in its analysis.
The Stack Health Score is a 0–100 rating that summarises how modern, secure, and well-maintained a website's technology stack appears to be. It factors in framework age, security header presence, CDN usage, and observable risk signals. It is unique to TrueTechFinder — no other free technology checker produces this score.
