ChatGPT on web, iOS, and macOS all using different background colors like it’s a multiverse of gray. Somewhere in a meeting: “We need consistency.” Designer: “Absolutely. Anyway, here’s a new gray.”

casually browsing around @npmx.dev and saw this. the feature is working well 😄

I thought I’d let ChatGPT narrow down hotels in Paris to 3 options. It gave me a map covered in blue dots. So yeah. Still choosing

I feel old right now. I remember when the scheduling profile was introduced, but old habits die hard, and I'm rarely looking there, and I wasn't following all the development happening in that tab. I guess it’s time to update myself 😅

AI that can write code is cool. AI that can write code, run it, see what's slow, and fix it? Even cooler 🚀 Next up visual state diffing, automatic perf regression detection 👀 What's the most annoying thing you debug in React?

Piotr Tomczewski @tomczew.ski · 11/02/2026

Getting started takes one line ⚡️ It detects your framework and configures everything automatically. Vite, Next.js, Expo, you name it. React and React Native 📱

Piotr Tomczewski @tomczew.ski · 11/02/2026

📊 Profile any interaction and see exactly what happened: 🔥 Slowest components by render time 🔁 Most re-rendered components 🎯 What triggered each render No more flame chart screenshots. Your AI reads this and knows what to fix.

Piotr Tomczewski @tomczew.ski · 11/02/2026

🌳 Component tree with stable IDs (@c1, @c2...) 🔎 Props, state, and hooks for any component 📊 Render profiling: slowest, most re-renders, trigger 🧠 Structured, token-efficient output your AI can reason about

100

Piotr Tomczewski @tomczew.ski · 11/02/2026

You tell your AI: "my app feels sluggish" 🐌 It opens your app, profiles it, finds the slow component, and fixes the code ✅ That's it. No DevTools. No screenshots. No back and forth.

100

Piotr Tomczewski @tomczew.ski · 11/02/2026

AI agents can see your DOM but they have no idea what's happening inside React 👀 Which component re-rendered? Why? What props changed? agent-react-devtools gives them direct access to your component tree, state, hooks, and profiler data 🔌

110

Piotr Tomczewski @tomczew.ski · 11/02/2026

I built a tool that gives AI agents access to React DevTools ⚛️🤖 Your AI coding assistant can now inspect components, profile renders, and diagnose performance issues completely on its own. Works with @cursor.com.web.brid.gy, @claudecode.bsky.social, Codex, Open Code, or any other you like

Just bought tickets for Robyn 🖤 And I love this idea: you can confirm a regular ticket, grab a discounted solidarity ticket if you need it, or pay a bit more to help cover someone else's. More shows should work like this

Piotr Tomczewski @tomczew.ski · 10/02/2026

Are you planning to bring the events info into the existing DevTools Profiler view?

100

Piotr Tomczewski @tomczew.ski · 10/02/2026

The whole tree doesn’t make sense it wouldn’t fit and it would be unreadable. I’m thinking more about showing the parent, or maybe a way to visualize when the parent triggered a re-render. Ideally, I’d love to have some sense of space and time awareness.

From Chrome 145 (on general release next week!), DevTools we will start to show so called "soft" navigations and "Soft LCP" in the Performance Panel traces. These are for SPAs which don't do a full page load, but instead "fake it" by updating the current page and pushing a new history entry. 1/5 🧵

Screenshot of a performance trace in Chrome DevTools with a few additional "Nav*" and "LCP*" markers. Hovering over the "LCP*" shows this is a "Soft LCP" and in the Summary panel when you click on it you see "Soft Largest Contentful Paint" and a "Learn more about Soft Largest Contentful Paint" link.

Is it the Max or the Maxest plan? 😂 I finally decided to upgrade my personal plan from Pro last weekend and now I’m running Claude on two computers simultaneously

Piotr Tomczewski @tomczew.ski · 10/02/2026

Very helpful for understanding scheduling. Will there be a way to inspect the event details that triggered the render? Have you considered exposing a way to correlate the Performance Tracks timeline with the component tree?

I love using dictation, but it’s the worst when it suddenly goes off the rails. I’m speaking English, and it transcribes everything in Polish or, in the most random case, Japanese (I still have no idea how that even happened). 😅

Piotr Tomczewski @tomczew.ski · 10/02/2026

AI can write UI fast. Debugging re-renders still feels… manual: Profiler → screenshot → explain to the model. Anyone found a better workflow?

Love getting target ads for things I actually want to buy only to find out every single one is sold out 🙃

Or you can be me and decide it’s time to upgrade to Max 😅

Giving acknowledgements to all awesome open source dependencies you use in your apps is not only a privilege, but in many cases a legal requirement. Instead of manually scrubbing through each and every dependency, our "react-native-legal" package will do it for you.
