VERDICT

Should I use TechnologyChecker.io?

Technology intelligence for sales & GTM teams. 40K+ tech detection, churn signals, and verified contacts on 29.9M live business domains. - technologychecker.io

Depends. Buy if your sales or GTM team prospecting by tech stack at scale — the data depth and churn signals are real. Skip it if you need occasional one-off lookups; free tools like Wappalyzer cover that at $0.

Confidence

Medium. Based on ~20 public sources; most product claims are vendor-published and only 7 independent G2 reviews exist, so treat ratings as early-stage.

Gotchas - check before you buy

API usage is credit-based per endpoint — costs can climb with volume

medium

Support tiers exist but quality is unverified — only 7 reviewers

low

Free tier capped at 100 lookups/month; trial data runs dry quickly

low

Vendor floods search with 'vs' and alternatives pages — validate independently
