Checkly strengths
- Playwright-native synthetic checks — great for E2E API flows
- Monitoring-as-code via CLI and Terraform
- 10-second check interval on Team tier
Where it falls short
- Aimed at engineers; agency/marketing use cases are secondary
- No visual change detection for marketing pages
- Priced per check run — high-frequency monitors get costly
