There are only a few companies that successfully invest in actively monitoring real user flows in production. I’ve been puzzled by the state of the art for many years, because I’m an anxious developer that always needs to know that production is “all right”. How can it be okay for all of us to wait for error logs, thrown exceptions or customer complains to learn about production issues? Shouldn’t knowing that all the systems are operational at all time be the ultimate monitoring goal? And why’s no one actively testing and monitoring core application flows in production to ensure that all customers are having a good time? The short answer: developers, QA engineers and SREs think that synthetic monitoring or “testing in production” is too hard. But is it really? We at Checkly have some news, so buckle up! Playwright has Taken over the End-to-end Testing Market The teams at Microsoft started working on the Playwright end-to-end testing framework in February 2020. If you fast forward to to

We've been running Playwright in production since the beginning. Today, we're going all in. When we first launched Browser Checks with Playwright support, we proved something critical: the most popular test automation framework since Selenium isn't just for testing—it's the foundation of modern production monitoring. But that was just the beginning. Today, we're announcing Playwright Check Suites—our bet on the future of monitoring and the most significant evolution in Checkly's history. From Browser Checks to Check Suites: Our Evolution Our Browser Checks introduced Playwright to production monitoring, but they came with constraints. We provided curated runtime dependencies, a single test spec per check, and a managed environment that worked well for many use cases. Playwright Check Suites removes every limitation. You're no longer adapting Playwright to fit our platform. You're running it exactly as you do locally—with full control over: Your entire playwright.config.ts — Every setti

In cybersecurity, defense-in-depth is a fundamental principle – you never rely on a single security measure to protect your systems. The same philosophy applies to application monitoring. No single monitoring approach, no matter how sophisticated, can capture every possible failure mode of your application. This is why layered monitoring isn't just a best practice – it's essential risk mitigation. The Cost of Blind Spots Every minute your application is down, you're not just losing revenue – you're losing customer trust, damaging your brand, and potentially violating SLAs. According to recent studies, the average cost of downtime ranges from $5,600 per minute for small businesses to over $540,000 per hour for enterprise applications. But here's the critical insight: different types of failures require different detection methods. A comprehensive monitoring strategy must account for various failure scenarios, each with its own risk profile and detection requirements. Understanding Your

When Checkly launched, it was the first of its kind, enabling developers to monitor complex workflows easier than ever using the automation tooling (Playwright, Terraform, etc) they already knew and loved. We’ve helped detect and resolve issues for 1000s of companies—ranging from monitoring crucial log-ins, to purchasing products, to setting up client instances for millions of monthly users But what about the simpler stuff?
