Free uptime test

Keep your site available around the clock with checks from multiple global locations every 60 seconds. Get instant alerts by email, Slack, or webhooks the moment downtime is detected so you can fix issues before users notice.

Simulate real user journeys in the browser to catch broken flows, JavaScript errors, and slow pages before they impact revenue. Build and maintain journeys without code, validate key steps like logins and checkouts with screenshots, and videos when something fails.

Track mission‑critical flows such as signup, checkout, and dashboards end‑to‑end, not just single pages. Acumen Logs surfaces failed network requests, console errors, and regressions in real time so your team can resolve UX issues quickly.

Add lightweight heartbeat checks to scheduled jobs and background workers so you know when something silently stops running. Get alerted on missed or late heartbeats, and review a history of successful runs to prove reliability to stakeholders.

Automatically watch your SSL certificates and domains for expiry so you never lose traffic or trust to a preventable error. Receive proactive reminders and status checks that help you stay compliant, secure, and interruption‑free.

Continuously test your REST and GraphQL endpoints for uptime, latency, and response correctness from regions that match your users. Validate status codes, schemas, and payloads, and trigger alerts when responses slow down or no longer match expectations.
