Engineering insights on monitoring, reliability, and developer tooling.
A step-by-step tutorial: write a Playwright check, capture failure evidence, schedule it against production, and alert on broken user journeys.
API testing validates correctness before deploy. API monitoring validates availability after. Same endpoints, different failure modes, different tools.
Define monitors in config files, review changes in PRs, deploy via CI/CD. The same discipline you apply to infrastructure, applied to observability.
7 synthetic monitoring tools compared on browser fidelity, authoring, locations, alerting, and the pricing model that predicts your bill. Verified June 2026.
You already write Playwright tests for CI. Here is how to run them as scheduled production monitors that catch broken user journeys before your customers do.
The practices that separate synthetic monitoring that catches incidents from a flaky setup crying wolf: what to check, what to assert, intervals, and alerting.
Synthetic monitoring runs scripted checks before users arrive; RUM records what visitors experience. Where each wins, what each misses, and why you need both.
Synthetic monitoring runs scripted checks against your app from the outside, on a schedule, before users hit the broken path. How it works and what to monitor.
