Velprove

The browser login monitor on the free plan is honestly a pretty strong differentiator. Most uptime tools only tell you the server is alive while the actual user flow is completely broken 😭

The distinction between "server returned 200" and "app actually works" is the exact gap that most monitoring tools ignore. Browser login monitors that capture a screenshot on failure are genuinely useful — that's the kind of evidence that cuts debugging time in half.

The free plan exists because that's the plan I would have needed when I started

I kept getting alerts that said my app was "up" while customers were emailing me about broken logins. Most uptime tools were happily polling a 200 OK and reporting green, even when the page was throwing a JS error, serving a stale cached response, or rejecting every login attempt with "invalid credentials." So I built Velprove around the thing that actually matters: a real browser that signs in like a user, completes the workflow, and verifies what an authenticated session actually sees. Not a 200 OK proxy. The free plan exists because that's the plan I would have needed when I started. 10 monitors including a browser login monitor, commercial use allowed, no credit card required. It's the same plan I run parts of my own production on. Would genuinely love feedback on what's still missing. I read every comment.

Velprove solves a real monitoring gap by checking whether the app actually works for users, not just whether an endpoint returns 200. The browser login monitor is the standout feature here, especially since offering real-browser auth checks on a free plan is pretty rare. I also like that it combines practical alerting, multi-step workflow checks, and public status pages, which makes it useful for small SaaS teams that need solid coverage without a lot of setup.

The approach of simulating a real user login instead of just pinging a URL is a genuinely clever distinction. Most outage alerts I've seen fire too late — after a customer already hit a broken checkout or a timed-out session. Having the failure screenshot automatically captured is particularly valuable for postmortems since you can see exactly what broke rather than just knowing something did. Curious whether you plan to support multi-factor auth flows in browser monitors down the road?
