Monitoring for SaaS & B2B software
Monitor the real user flows your business is built on
Checkly runs your Playwright suite as production monitors, every few minutes, from the regions you sell in. A checkout that breaks, an A/B variant that converts to nothing, one tenant locked out of SSO: you see it in an alert, not in next week's funnel report.
Trusted by the software teams your customers depend on
“The team spends less than 1% of their time managing Checkly.”
The outage your dashboard averages away
Multi-tenant software fails one tenant at a time. Fleet-wide numbers are built to hide exactly that.
Green in aggregate, broken for one customer
Per-tenant config, feature flags, custom SSO, custom domains. A fleet-wide uptime number averages all of it away, and the one tenant who cannot log in never shows up in it.
The flows that decide revenue never run in production
Signup, SSO login, teammate invite, plan upgrade, API key issuance. Covered thoroughly at merge, then never exercised again against the environment customers actually use.
Your customer files your incident report
Support hears about it before on-call does. The gap between their first failed login and your first alert is the part that comes back up in the renewal conversation.
Checkly runs the flow itself, per tenant, from the regions your customers sign in from. A failure names the tenant, the step, and the release it started on.
“Checkly is a fabulous developer tool. The flexible features and developer-friendly API made the integration super easy, and their support is friendly and knowledgeable.”
