Velprove tells you whether your web app actually works, not just whether the server returned a 200.
Most uptime tools ping a URL and stop. That misses the outages that cost revenue: a broken login, a checkout that times out, an API that returns 200 with an empty body.
Four monitor types, all on the free plan
- HTTP and Ping for availability and response time.
- API monitors that assert on status code, body, headers, response time, and JSON paths.
- Multi-step API monitors that chain requests to test a full workflow like auth or checkout (3 steps Free, 5 Starter, 10 Pro).
- Browser login monitors: Velprove opens a real browser, signs in, and confirms authentication succeeded, capturing a screenshot the moment it fails.
Why Velprove
The browser login monitor is the difference. A real-browser login test available on a free plan is rare, and it catches the failures a status-code ping never sees: expired sessions, broken redirects, a login form that silently stopped working.
Alerts route to email, Slack, Discord, Microsoft Teams, webhooks, and PagerDuty, with a failure threshold so a single blip never wakes you. Publish public status pages, monitor from 5 global regions, and keep detailed history and trends for SLAs and postmortems.
Plans
Free $0 (10 monitors), Starter $19/mo (30), Pro $49/mo (100, custom-domain status pages, PagerDuty, priority support). No credit card required, and the free plan never expires.
Built for solo founders, small SaaS teams, DevOps, and agencies running revenue-critical sites and APIs.
Features
- Browser login monitor: drives a real browser through your sign-in page and asserts on what authenticated users see (the killer feature)
- HTTP monitor: status code + body assertions for marketing pages, content sites, and basic uptime
- API monitor: JSON path assertions, header checks, response time budgets for API endpoints
- Multi-step API monitor: chain HTTP calls together with response extraction between steps (3 free, 5 Starter, 10 Pro)
- Pick from 5 monitoring regions on every plan (NA, EU, UK, Asia, Oceania)
- Failure screenshots show what the monitor saw when it flagged (1 Free, 5 Starter, 30 Pro)
- SSL certificate expiry alerts included on every plan
- Public status pages with custom logo (1 Free, 3 Starter, 10 Pro with custom domain)
- Alert channels: email (every plan), Slack, Discord, webhook, Microsoft Teams (Starter and above), PagerDuty (Pro)
- Commercial use allowed on the Free plan, no credit card
Use Cases
- SaaS apps: monitor login flows, API endpoints, and dashboards with browser login monitors. Catch auth failures before users do.
- REST APIs: validate responses with JSON path assertions and chain multi-step auth flows (OAuth, JWT refresh, API workflows).
- WordPress sites: monitor wp-admin login with a browser login monitor. Catch plugin conflicts, PHP errors, and broken authentication instantly.
- WooCommerce stores: catch broken checkout flows, payment gateway failures, and plugin conflicts before customers do.
- Shopify stores: monitor product pages, checkout, and admin login. Catch silent failures the Shopify status page will not tell you about.
- WHMCS hosting portals: watch client portal login for PHP update failures, module conflicts, and broken authentication.
- Agencies: up to 10 branded client status pages on Pro, real-user monitoring for 10+ client sites on one plan.
- Third-party dependency monitoring: watch Stripe, SendGrid, OpenAI, GitHub API health from your own app's perspective, not the vendor's status page.
Comments
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.
