Why People Leave Wappalyzer

The Dealbreaker: API Coverage

Wappalyzer's free tier and browser extension are useful for quick lookups, but the API — needed for bulk lookups and automated research workflows — starts at $250/month. This makes programmatic tech stack detection prohibitive for most developers and small teams.
