People keep asking us here at Checkly if and how AI can help create solid and maintainable Playwright tests. To answer all these questions, we started by looking at ChatGPT and Claude to conclude that AI tools have the potential to help with test generation but that "normal AI consumer tools" aren't code-focused enough. High-quality results require too complex prompts to be a maintainable solution.

If you’ve ever been floored by a sub-100ms response time, you’ve likely got caching to thank. Caching is the unsung hero of performance, shaving precious milliseconds off your application’s response time by storing frequently accessed data, avoiding yet another round-trip request to the database or API. Let’s break down how caching works and explore a few common strategies.

Last week, I attended one of the last conferences of the year with team Mezmo: the Gartner IT Infrastructure, Operations & Cloud Strategies Conference in Las Vegas. Not surprisingly, there were over 20 sessions covering observability and how it is getting increasingly critical in the new complex distributed computing environment. Of course, there were many sessions, including all keynotes that addressed the advent and impact of AI on IT operations and observability.

From AI to eBPF, 2024 reshaped the observability landscape. As we peer into 2025, Grafana Labs’ experts predict another year of innovation that will redefine how teams understand and optimize their systems, from profiling to platform engineering. Their insights align with what the community is saying, according to early responses from our third annual Observability Survey. Do you agree or disagree with the trends our team believes will transform the world of observability next year?

Organizations exploring Kubernetes alternatives often face a critical decision when choosing the right container orchestration solution. While Kubernetes has established itself as the industry standard, companies are increasingly seeking alternatives that better align with their deployment needs, team expertise, and operational requirements. This comprehensive guide examines the top alternatives to Kubernetes, helping you make an informed decision for your 2025 container strategy.

Have you ever had an alert go off that you immediately ignore? It’s a nuisance alert—not actionable—but you keep it around just in case. Or maybe you’ve looked at a trace waterfall and wondered what exactly happened during a gap that just doesn’t drill down deep enough to explain what’s going on. Do you know the feeling where you have just enough information to monitor what’s going on in your systems, but not quite enough to put your mind at ease?

With systems more interconnected than ever, the ability to communicate quickly and efficiently has become crucial today. This is where gRPC, an open-source framework by Google, comes in to transform the way APIs are designed and utilized. In this blog, we will explore what gRPC is, how it works, how it differs from existing protocols like REST, and the best practices for Optimizing its full potential.

When systems fail, every second counts. The difference between prolonged downtime and swift resolution often comes down to one critical role: the Incident Commander (IC). ICs are the backbone of calm and clarity in the middle of chaos. Let’s unpack what an Incident Commander does, why they matter, and how you can step into this crucial role.

Did you know that 54% of IT professionals identify detecting vulnerabilities as the hardest part of the patching process (Adaptiva)? In a world where cyber threats are going to be more evolutionary and at a faster pace, one undiscovered vulnerability could still leave an organization exposed. That is where patch scanning comes in.

Let's face it-Mac Patch Management can be like trying to hit a moving target. There's always some new security vulnerability lurking around the corner, some critical patch that needs deploying, or some pesky third-party app demanding attention. If you're managing a mixed bag of Mac devices, you already know the stakes: falling behind on updates can mean cybersecurity threats, data loss, or worse-downtime.
