Checkly vs Sentry

From $24 per month (Starter; Team is $64)

From $26 per month (Team plan, indicative)

Priced by check runs; browser checks cost more than API checks, and frequency multiplies the bill. Team at $64 adds 75 monitors, 30-second frequency, all 22 locations and private locations.

Event-volume pricing. A noisy application can consume the quota quickly, so filtering matters.

Hobby: 10 uptime monitors, 10k API and 1k browser check runs a month across 6 locations.

Free developer plan with a monthly error and replay allowance.

• One Playwright script serves as both an E2E test and a production monitor.
• Monitoring-as-code fits GitOps workflows and code review.
• Excellent developer experience and clear, published pricing.

• Release and commit attribution tells you which deploy introduced the error, and often who to ask.
• Excellent SDK coverage across essentially every language and framework.
• Self-hosting is genuinely supported for teams that need it.

• Playwright-centric; teams on other frameworks get less benefit.
• Browser checks at high frequency across many locations get expensive.
• Not a full observability platform — no APM or log management.

• Event-based pricing punishes noisy applications until you invest in filtering.
• The product has broadened a lot; some newer modules are shallower than the error core.
• Self-hosting is resource-hungry.

Engineering teams already using Playwright who want production journeys monitored.

Essentially every engineering team — error tracking is the highest-value monitoring you can add first.
