Checkly vs Selenium vs supaguard (2026 Comparison)
Comparing Checkly, Selenium, and supaguard for synthetic monitoring. Find out which tool is best for your team's needs.
Evaluating synthetic monitoring tools can be overwhelming. Today, we're comparing three major players: Checkly, Selenium, and supaguard.
Checkly
Best for: Developers who want to write and maintain raw Playwright code.
Checkly popularized the "Monitoring as Code" movement. It integrates well with CI/CD and uses Playwright natively. However, it forces teams to write code for every monitor, leading to high maintenance costs and "brittle test syndrome."
Selenium
Best for: Legacy enterprise teams or basic uptime checking.
Selenium is a known name in the industry. While it may offer broad features, it often lacks the modern, AI-native capabilities required by fast-moving development teams. Tests can be flaky, and the pricing can be opaque.
supaguard: The Modern Alternative
Best for: Fast-moving teams who want reliable monitoring without writing scripts.
supaguard is the new standard. It uses AI to generate, execute, and self-heal your monitoring flows.
Feature Comparison
| Feature | Checkly | Selenium | supaguard |
|---|---|---|---|
| AI-Native | ❌ No | ❌ No | ✅ Yes |
| Self-Healing | ❌ No | ❌ No | ✅ Yes |
| Unlimited Seats | ❌ No (Per seat) | Varies | ✅ Yes |
| Setup Speed | Hours | Hours | Seconds |
Summary
If you enjoy writing code for tests and have a large QA budget, Checkly is a solid choice. If you want legacy reporting, Selenium works.
But if you want zero-maintenance, highly resilient synthetic monitoring that your whole team can use, supaguard is the absolute winner.
