Observable technology intelligence
See the stack. Prove the signal. Track what changed.
TechStack Radar turns safe public website observations into deterministic evidence, normalized stack snapshots, and confirmed technology change history.

CHANGE SPINE
Confirmed additions, removals, and reappearances.
No confirmed change events yet.
Observe a domain over time to create history.

Evidence First
Every public detection is backed by normalized response headers, HTML markers, cookies, or referenced asset URLs.
Change Aware
Baseline is not “added.” New and removed technologies require repeated comparable observations before publication.
Boundary Safe
No vulnerability scanning, DNS-derived technology inference, recursive crawling, browser execution, or third-party asset fetches.
