Velprove

Uptime monitors check if your server responds. Velprove checks if your users can actually log in. Most monitoring tools ping a URL and tell you it returned 200 OK. But a 200 doesn't mean your login form works, your API returns correct data, or your checkout flow completes. Velprove runs 4 types of checks: - HTTP/Ping — Standard uptime monitoring - API Validation — Assert on status codes, JSON paths, response body, and headers - Multi-Step API — Chain sequential requests that pass data between steps to test full workflows - Browser Login Checks — A real headless browser visits your login page, fills credentials, clicks submit, and verifies authentication succeeds. If it fails, you get a screenshot of exactly what went wrong. Free plan includes 10 monitors and 1 browser login check. No credit card. No trial. Just monitoring that actually tells you if your app works.
