Highlights
🎉 The playwright npm package just surpassed Cypress 🚀. (green vs. orange) 👇
The usage of Playwright is on a steady rise, a clear indication of its growing popularity. It's only a matter of time before the Playwright-core package outshines Cypress in terms of downloads, with all other packages already surpassing it.
It's fantastic to see that this trend continues, looking forward to how browser automation evolves in the next years.
We at Checkly are big fans of Playwright as it enables very stable automation and, with that, production monitoring across multiple websites at scale. Even more, it enables you to codify your monitoring.

Blog alert: How We at Checkly Shaved Off Months of Runtime with OTEL traces 👇
Engineers, have you ever wondered if your code needs monitoring if it’s already well-written and tested? Think again. Jan Grzesik, one of our talented engineers at Checkly, shared a fascinating story about how we significantly improved our system’s efficiency with the help of OpenTelemetry (OTEL) traces.
We faced unexpected delays in our 'housekeeping' processes—tasks that run after every check to log traces and send status updates. By integrating OTEL for monitoring and using Coralogix for data visualization, we uncovered a subtle but impactful issue: multiple redundant AWS authentication requests. A simple fix, saving the authentication results locally, shaved off 40 milliseconds per task.
Now, 𝟰𝟬 𝗺𝗶𝗹𝗹𝗶𝘀𝗲𝗰𝗼𝗻𝗱𝘀 might not sound like much, but when you’re running hundreds of millions of checks monthly, it adds up. In fact, we saved 𝗼𝘃𝗲𝗿 𝟭𝟭𝟱 𝗱𝗮𝘆𝘀 𝗼𝗳 𝗲𝘅𝗲𝗰𝘂𝘁𝗶𝗼𝗻 𝘁𝗶𝗺𝗲 𝗶𝗻 𝗮 𝘀𝗶𝗻𝗴𝗹𝗲 𝗺𝗼𝗻𝘁𝗵! This optimization not only boosted performance but also slashed our infrastructure costs. 🚀
𝗞𝗲𝘆 𝗧𝗮𝗸𝗲𝗮𝘄𝗮𝘆𝘀: 𝟭. 𝗖𝗼𝗻𝘁𝗶𝗻𝘂𝗼𝘂𝘀 𝗠𝗼𝗻𝗶𝘁𝗼𝗿𝗶𝗻𝗴 𝗠𝗮𝘁𝘁𝗲𝗿𝘀: OTEL helped us identify issues that were impossible to predict or pre-optimize.
𝟮. 𝗛𝘂𝗺𝗮𝗻 𝗜𝗻𝘀𝗶𝗴𝗵𝘁 𝗶𝘀 𝗖𝗿𝘂𝗰𝗶𝗮𝗹: Manual inspection of traces revealed the root cause of our delays.
𝟯. 𝗦𝗺𝗮𝗹𝗹 𝗖𝗵𝗮𝗻𝗴𝗲𝘀, 𝗕𝗶𝗴 𝗜𝗺𝗽𝗮𝗰𝘁: Minor optimizations can lead to significant efficiency gains.
𝟰. 𝗠𝗼𝗻𝗶𝘁𝗼𝗿𝗶𝗻𝗴 𝗮𝘀 𝗖𝗼𝗱𝗲: Integrating monitoring into the development workflow enhances visibility and reduces surprises.
Observability isn’t just a buzzword—it’s a game-changer. The insights you gain can lead to profound performance and cost-efficiency improvements.
Check out Jan's full story on our blog (1st comment) to dive deeper into how we achieved this and the role of observability in modern software development.
