Velprove

Free uptime monitoring with real browser login checks and API testing

Traditional uptime monitors ping a URL and tell you the server responds. Velprove goes further — it launches a real browser, navigates to your login page, types credentials, clicks submit, and verifies your users can actually log in. We built this because we kept finding out about broken login flows from customer emails, not from our monitoring dashboard. A 200 OK on the homepage does not mean the login works. Velprove offers four types of checks — all available on the free plan: 1. HTTP/Ping — Standard uptime monitoring 2. API Validation — Assert on JSON responses, headers, status codes 3. Multi-Step API — Chain requests to test full workflows (up to 3 steps free, 5 Starter, 10 Pro) 4. Browser Login — Real headless Chromium verifying authentication with failure screenshots Free plan: 10 monitors, 1 browser login check, multi-step API checks, email alerts. No credit card. Commercial use allowed. Starter: $19/mo. Pro: $49/mo.
