- Developers wiring site monitoring into apps or agents
- Worth noticing
- The free demo returns a real tech-stack response without an API key; the page also shows HMAC-signed webhook examples.
Field notes
The homepage demonstrates a no-key tech-stack lookup and shows a trimmed response with detected technologies, categories, confidence values, and detection sources. For monitoring, the described sequence is scheduled checks, stored state, change detection, then a signed JSON webhook; the page says empty checks cost less than full-price results and failed calls are free. Documentation links include an API reference, OpenAPI files, and llms.txt.
