Cypress and Checkly are often evaluated together by teams building out their reliability stack. Cypress (javascript end-to-end testing framework, founded 2015) is typically a fit for Frontend Developers and QA Engineers, while Checkly (api and e2e monitoring for developer teams, founded 2018) leans toward Backend Developers, DevOps Teams, and QA Engineers. Both cover 6 of the same core capabilities, so the decision usually comes down to where they diverge.

Checkly covers more unique ground in this comparison, notably Synthetic Monitoring, Uptime Monitoring, Alerting, and Multi-Location Checks, among others. That said, Cypress (Open source free. Cloud Team from $67/mo (10k test results)) is the better choice when Open Source and On-Premise / Self-Host is a priority.
Cypress is javascript end-to-end testing framework, while Checkly is api and e2e monitoring for developer teams. Cypress adds Open Source and On-Premise / Self-Host on top of the shared feature set. Checkly brings Synthetic Monitoring, Uptime Monitoring, and Alerting that Cypress does not.
Cypress pricing: Open source free. Cloud Team from $67/mo (10k test results). Checkly pricing: Hobby (Free), Starter $24/mo, Team $64/mo (100k API, 12k Browser runs). Evaluate against your check volume and team size; entry pricing rarely reflects total cost at scale.
Cypress is designed with Frontend Developers and QA Engineers in mind, whereas Checkly targets Backend Developers, DevOps Teams, and QA Engineers. If your team matches the former profile, Cypress is usually the closer fit.
