Aun estás a tiempo de apuntarte a esta formación para detectar problemas de rendimiento web con agentes de IA #WebPerf #IA #MCP

This is why the Chrome DevTools MCP is a game-changer. The agent applies a fix, reloads ignoring cache, runs a Lighthouse audit, and checks the score to iterate on the next failure. Fully automated and deterministic. #AgenticDev #WebDev #AI

I think I may have found a memory leak in LinkedIn A single browser tab was consuming 6 GB of RAM just from leaving the feed open for a while Possible causes: • client-side state leaks • excessive caching • unreleased media resources • runaway DOM growth Performance is a feature #WebPerf

Safari and Firefox change how big sites render based on the domain. TikTok, Netflix, Instagram… even SeatGuru. Chrome doesn’t. Why is that? denodell.com/blog/browser... by @denodell.bsky.social #Browser

¿Buscas optimizar el rendimiento de tus aplicaciones con agentes de IA? En este workshop aprenderás a conectar el Chrome DevTools MCP a un agente para automatizar la detección de problemas. Veremos cómo generar reportes técnicos, de cliente y de management 👇 ¡Inscríbete aquí! #WebPerf #AI #MCP

Running performance audits by hand, scripts in DevTools, results scattered, is fine until you're doing it on every project I built PerfReviews Insights to skip that. URL in, structured report out. Fonts, images, CSS, LCP, TTFB. Pro accounts keep full history perf.reviews/insights #WebPerf

El agente de IA no sabe debuggear rendimiento si tú no le das el contexto para hacerlo. No es que sea malo. Por defecto trabaja a ciegas: sin acceso al navegador, sin trazas reales. #WebPerf #Performance #AIAgents #ChromeDevTools #Frontend

I've finished the #WebGPU in the browser series. 4 articles: fundamentals, image processing, real-time ML, and video editing Never written a shader before starting. In the last article we process video at 2ms per frame with WebGPU + WebCodecs joanleon.dev/en/webgpu-br... #WebPerf #JavaScript

I've added a new snippet to WebPerf Snippets: Forced Synchronous Layout Detector Run it in DevTools, trigger the interaction, and get a real-time warning with the property, element, & stack trace every time FSL hits webperf-snippets.nucliweb.net/Interaction/... #WebPerf #DevTools #WebPerfSnippets

Toggle CSS classes in bulk, then reset the scroll: two lines that force the browser to block the main thread synchronously. I documented how to detect it in the Performance Panel and why one requestAnimationFrame is not enough to fix it. #WebPerf #CSS #DevTools #JavaScript

Layout shifts often only happen at specific screen sizes or after a user interaction. That's why I built a new free tool: the CLS checker tests your site at 5 different viewport sizes and scrolls down the page. Try it out here: www.debugbear.com/test/cls

What an illusion to coincide again after so many years ☺️ I loved your talk, having been able to chat for a while and coincide with the love for photography 📷 Un abrazo 🤗

Thanks to Codemotion for giving me the opportunity to continue sharing my knowledge on #WebPerf (aka improving the UX), and to do so in a workshop format where we use Chrome DevTools MCP to identify performance issues on a website with AI agents. #WebPerf #PerfTools #DevTools #CodemotionMadrid

I wrote about the experimental chrome-devtools-mcp CLI: a persistent daemon and direct subcommands to control Chrome from the terminal without writing code. Network, performance, Lighthouse, memory, interactions. All from the shell. joanleon.dev/en/chrome-de... #WebPerf #DevTools #JavaScript

A Gaussian blur in Canvas 2D takes 280ms. The same filter with WebGPU: 8ms. I wrote the second article in the WebGPU series: image processing in the browser with WGSL shaders and real benchmarks. joanleon.dev/en/webgpu-im... #WebPerf #WebGPU #JavaScript #Performance

We've made a bunch of UI changes, including making it easier to trigger synthetic tests on demand and add chart annotations.

That project AI was helping me with that I was so excited about a while back? It's finally ready enough for some public exposure: I bring you "Waterfall Tools": blog.patrickmeenan.com/2026/04/12/i...

Sometimes opportunities come along that push you out of your comfort zone. An international product, millions of visits, and impact at scale. Definitely an exciting challenge. #WebPerf #CoreWebVitals #PerfChallenge

For years, the performance ceiling in the browser has been clear: the CPU. WebGPU changes that. 🧵 It’s not a library or a framework. It’s a browser API that gives direct access to the device’s GPU, enabling a level of parallelism the CPU cannot match. #WebPerf #WebGPU

Software is evolving fast. My focus hasn’t changed: helping teams improve performance, UX, and conversion AI generates working code faster than ever… but not optimized for performance That’s where we add value: from “it works” to “it’s excellent” Reading @addyosmani.bsky.social’s new book

A measurement that varies with the model's interpretation is not a measurement. It's an estimate. I've written about separating deterministic measurement from AI analysis in web performance audits. #WebPerf #Performance #PerfReview #AI #DevTools

Chrome is bringing AI directly into the browser with the Summarizer API. In this post I show how to add an AI-generated summary to blog posts using the Chrome Summarizer API and models running locally in the browser. No external APIs. No token costs. #AI #WebAI #JavaScript #Chrome

I built a free tool to analyze web performance: no login, no setup. Paste a URL → get an instant report on images, videos, page weight and third-party scripts. It's in beta. Try it 👇 #WebPerf #Performance #PerfInsights

Muchas webs siguen sirviendo imágenes PNG de 2–3 MB. Pero esas mismas imágenes pueden pesar menos de 50 kB. La optimización de imágenes sigue siendo uno de los mayores problemas de rendimiento en la web. Hilo 👇
