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_ai , @claudeai Code, @OpenAI Codex, @opencode , or any other you like

@DanStepanov @nativewindcss @SzymonRybczak You can use agent-device to automate simulators and interactions, and agent-react-devtools to profile the react part, but I’m guessing you’d also want to measure native stuff? We’re thinking about adding native profiling. What exactly would you like to measure?

Biggest hold up in working on @nativewindcss is having agents able to spin up simulators for apps and interact with them/use instrumentation to measure different stuff without the need for manual interaction. Curious who is working on this problem @SzymonRybczak

You’ve been on a bad streak with communication. Two week promo with higher limits, then even lower regular limits right after and no clear communication until people noticed. Now more cuts, timed for a holiday weekend. Hard to tell if this is bad faith or just poor judgment, but either way it is frustrating

Starting tomorrow at 12pm PT, Claude subscriptions will no longer cover usage on third-party tools like OpenClaw. You can still use these tools with your Claude login via extra usage bundles (now available at a discount), or with a Claude API key.

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.”

Introducing: Agents Commander. The missing communication protocol for diverse agents working on a single machine. Let's code like it's 1986, but with agents! npm i -g agents-commander

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

Nie mam słów w języku publicznie akceptowalnym na opisanie tej antyludzkiej patologii, jaką jest żerowanie biznesu i chciwości na publicznej ochronie zdrowia, na życiu i zdrowiu ludzi. Ale mamy za to rozwiązania. Twarde rozcięcie organizacyjne oraz personalne prywatnego od publicznego. Zasada albo-albo: albo pracujesz w publicznym szpitalu albo prowadzisz własną klinikę. Na wczoraj.

97 proc. chorych na raka przyjętych poza kolejką. Ujawniamy wyniki kontroli w rządowym szpitalu. Miałeś nowotwór trzustki i zapłaciłeś kilkadziesiąt tys. zł – operacja z dnia na dzień z wykorzystaniem najnowocześniejszego robota. Zapłaciłeś 1150 zł za prywatną wizytę u kierownika kliniki – sprzęt starszy, ale termin równie szybki. Tak wyglądały realia w rządowym Państwowym Instytucie Medycznym. @portalzeropl @JakubStyczynski zero.pl/news/nfz-97-pr…

Sad to see Messenger Desktop go. It was the most visible (if not the only) @reactnative desktop app from Meta. Now Meta has little incentive left to push RN on desktop, leaving Microsoft as essentially the sole stakeholder. Seems like nobody can really shake @electronjs.

How do I debug Next.js app performance if the Chrome DevTools Performance tab just crashes while processing traces? 😅

I remember Agent Conf in 2023 vividly as one the best conference experience in my life. Thankful to @guntrambechtold for all the years organizing and having me there. New beginning for @AgentConf is coming 🔜👀
Guntram Bechtold@guntrambechtold

We officially hand over @AgentConf to a new organizing team at @callstackio. 10 events. 7 years. Hundreds of engineers from around the world in Dornbirn. In November 2016 I had an idea: a React conference in Vorarlberg. No budget, no team, no track record. Eight weeks later, 100 developers stood in the Raiba Im Rheintal in Dornbirn. Christoph Pojer from Facebook opened the stage. Max Stoiber called it "the most epic conference ever." What started as a local idea became something we never could have imagined: AgentConf became one of ten official Facebook JS conferences worldwide. Core engineers from Facebook, Microsoft, LinkedIn, Amazon, and SoundCloud came to Vorarlberg -- not Berlin, not Vienna. To Dornbirn. And then skiing in Lech. We sold tickets at EUR 1,400+ to people who had never heard of Dornbirn. At the same time, Martin, 17, a vocational school student, scraped together his euros for a Super Early Bird ticket. Both sat on the same chairlift in Lech. That was the core of Alpine Conferences: no gatekeeping. World-class content. And an environment you cannot manufacture -- conversations at 2,000 meters, apres-ski with the people whose open-source projects you use every day, friendships that last for years. In 2018, WorkerConf joined the family. Node.js, backend, infrastructure. Summer instead of winter. Hiking instead of skiing. Same principle: deep technical content combined with the nature that makes Vorarlberg unique. During the pandemic, we adapted -- digital formats, goodie boxes shipped to your door, a bike challenge where every meter generated donations to Open Collective. Not perfect. But honest. 2023 was the final AgentConf. Kent C. Dodds ran a React workshop. 16 speakers on the single-track stage at Spielboden. Two days in Lech. A fitting end. What remains: The conviction that a region like Vorarlberg can hold its own on the global tech map. Not by imitating Silicon Valley. But by building something of its own. A network of engineers who met in Dornbirn and now build products together, run companies, and drive open-source projects forward. Proof that premium events can be built and sold internationally from a small Alpine region -- when the format, content, and community are right. The conferences are now in new hands. The community stays. -- Thank you to everyone who made this possible: Team & organization: @tomsvogel -- co-founder and partner in crime from day one. Daniel Rotter -- co-organizer and developer at Sulu/MASSIVE ART. Phuc -- you welcomed the community on stage. arkulpa GmbH -- content curation and speaker lineup since the very first edition. Nina Broell -- photography. Pia Pia Pia -- aftermovies. Speakers across the years (AgentConf & WorkerConf): Christoph Nakazawa (@cpojer), Max Stoiber (@mxstbr), Nik Graf (@nikgraf), Kent C. Dodds (@kentcdodds), Sara Vieira (@NikkitaFTW), Nadia Makarevich (@adevnadia), Glenn Reyes (@glnnrys), Jani Evakallio (@jevakallio), Vladimir Novick (@VladimirNovick), Monica Lent (@MonicaLent), Jan Monschke (@thedeftone), Svanlaug Ingolfsdottir, Patrick Stapfer (@ryyppy), Brent Vatne (@notbrent), David Khourshid (@DavidKPiano), Balint Erdi, Tereza Sokol, David Shedrick, Mike North, Andrey Okonetchnikow, Mats Bryntse, Saskia Vola, Nacho Martin (@nacmartin), Johannes Schickling (@schickling), Tejas Kumar (@TejasKumar_), Daniel Thompson-Yvetot, David Leitner, Michael Bromley (@MichaelBromley), Michael Arnaldi, Lisi Linhart (@LisiLinhart), Shivay Lamba (@HowDevelop), Konstantin Tkachuk, Onur Kasimlar, Johannes Moser, Mika Naylor, Matteo Collina (@matteocollina), Tomas Della Vedova (@daborelvedor), Tierney Cyren (@bitandbang), Tracy Lee (@ladyleet) -- and every other speaker I cannot name individually here. Every single talk made a difference. Partners & sponsors: Massive Art, valantic, Fusonic, Blum Group, illwerke vkw, Prisma, Xata, Herburger Reisen, Spielboden Dornbirn, Conrad Sohm Dornbirn, Stadt Dornbirn, Marke Vorarlberg, Chancenland Vorarlberg, Wirtschaftskammer Vorarlberg, FHV - Vorarlberg University of Applied Sciences, Dornbirn Tourismus. #AgentConf #WorkerConf #AlpineConferences #OpenSource #Vorarlberg #React #JavaScript #NodeJS #TechCommunity #Dornbirn #Lech #Arlberg #SoftwareEngineering
