Checkly FAQ
Common questions about Checkly, answered from independent, dated evidence.
What is Checkly?
A synthetic monitoring platform that sends real requests to your APIs and websites from distributed locations, tracks uptime and performance metrics, and automatically alerts your team through incident management and chat integrations when issues occur. It is indexed under API Monitoring.
Is Checkly free?
Checkly offers a free tier, so you can start without paying. Pricing changes often, so verify at source before relying on it.
What platforms does Checkly support?
Checkly supports the web and a command-line interface. Platforms we have not confirmed are simply not listed here rather than ruled out.
Can Checkly be self-hosted?
We have only confirmed a cloud / SaaS deployment for Checkly, so it appears to be vendor-hosted. If a self-hosted option exists we have not found it documented publicly.
What does Checkly integrate with?
We have confirmed 17 integrations for Checkly, including Slack, PagerDuty, Incident.io, Rootly, OpsGenie, GitHub, GitLab CI and Jenkins, plus 9 more. This is what we could verify from public sources, so the vendor may support others we have not indexed.
What security certifications does Checkly have?
We have independently confirmed SOC 2 for Checkly. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as Checkly not holding them. Always confirm compliance directly before you rely on it.

The vioscaleAI score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Checkly, not the verdict.
