Interaction to Next Paint (INP) is a newer addition to the Core Web Vital metrics intended to measure how real users perceive the responsiveness of modern web applications. Web Vitals Measurements like INP are becoming increasingly important as web applications and SPA’s run more JavaScript on the client side.

That thing where you are so pissed at a broken web application that you furiously click the button or link. Yea, we all do that. Rage clicking, or repeatedly clicking out of frustration, is a common experience for many users. However, while rage clicking may seem like a harmless expression of frustration, it can lead to negative outcomes for both users and businesses. It’s also a fantastic way to detect user frustration.

Website performance is critical to understand user experience and engagement, but there are so many different metrics! What do they all mean? Not to worry, dear reader, I got your back. Let’s break down Time to Interactive or TTI, why you should care about it, and how to make it blazingly fast. In today’s fast-paced digital world 🙄, website performance plays a crucial role in user experience and engagement.

We just released support for custom metadata in Request Metrics! Metadata allows you to describe your user, session, application, environment, account, A/B Test, or whatever else is meaningful for you. You can add metadata through the browser agent API, and report & filter on it in the Reporting UI.

A Request Metrics customer asked for some help troubleshooting poor scores on their Core Web Vitals, specifically the Largest Contentful Paint. I did a deep dive on their site and recorded my debugging session, so you can see how I went about finding the root cause.

Google Analytics was the go-to analytics tool. It set the standard, we all learned on it, and we all used it. But Google Analytics 4? It’s a nightmare. I’ve tried to figure it out for weeks and it’s just…confusing.

Seems like everyone is building a ChatGPT thing right now, doesn’t it? Well we are too! Inspired by so many others, we decided to see what AI could do with our simplified analytics and observability data. Turns out, it can do quite a lot. I’m thrilled to share that we’ve shipped our first AI insights chatbot, Professor Sloth.

In 2021, we started Request Metrics as a simple and developer-friendly service to measure and improve web performance. We built an incredible platform that distilled complex data down into simple reports and recommendations. Lots of teams around the world found valuable insights in Request Metrics that they couldn’t get anywhere else. But web performance data can be very unpredictable—the web slows down in all sorts of ways.

You can hardly even talk about web development without mentioning JavaScript. Because of its popularity, JavaScript has given birth to several frameworks and libraries that developers can barely keep up with. This post will discuss two popular JavaScript front-end frameworks and libraries: Svelte vs React and their performance. We’ll determine if Svelte is faster than React or whether Svelte is better than React. We’ll also compare the two to determine which is better for performance.

Largest Contentful Paint (LCP) is a measurement of how long the largest element on the page takes to render. It’s one of several Web Vital metrics that measure how real users perceive the performance of modern web applications. New measurements like Largest Contentful Paint are increasingly important as JavaScript and SPA’s render more content after page load is completed.
