In a surprise move, Snapchat open sources its cross-platform UI Valdi. Valdi lets devs write UI components in TypeScript then compiles them to native views on iOS, Android, and macOS, offers instant hot reload without recompiling, and integrates well into already existing native apps. GitHub Universe 2025 wrapped up just a few weeks ago, and it had a bunch of new AI agent updates to share. Think: a single source to manage agents across GitHub, Mobile, CLI, and VS Code, custom agents wit...

This week is a news roundup while cohost Jack is away for a hackathon in SF. First up, is how Chrome DevTools has added AI to its panels. Now users can ask Gemini to explain console errors, make CSS changes via in the elements tab, and explain traces collected in the performance panel. HTMX has also jumped from v2 to v4 (alpha), rebuilding the internals after 5 years of maintaining the project. Upgrades include: going from XMLHttpRequests to fetch, explicit attribute inheritance, and im...

It’s been almost 3 weeks since the React Compiler hit v1.0 and Jack gives an update on the ease of adding it to a React-based project and immediate performance improvement he’s seen from it. Popular AI-powered IDE Cursor just released v2.0, and it’s going hard on the agent mode, offering things like: a multi-agent interface where agents can run in parallel working on the same task with different models, and a new frontier model that’s 4x faster. Then the hosts then get existential about...

Another week, another new AI-browser. This time it’s OpenAI’s turn to introduce ChatGPT Atlas. As with the other AI browsers, Atlas knows the context of open tabs, has an agent that can do things for you, and (maybe its defining feature) it has "memory" built in so conversations can draw on past chats and details when needed. The team behind Vite reveals their path to revenue with command line devtool Vite+. Devs will soon be able to test, lint, format, bundle, and even view their apps’ stats...

Back in May, the Remix cofounders revealed they were reimagining Remix v3 from the ground up, and this past week at Remix Jam, they gave a sneak peek of it. It’s fair to say this new framework shouldn’t be called Remix at all because it’s departed so far from its origins: devs manually update state, it uses signals, routes are defined in a TS doc, and it will ship with a component library, for starters. Will it catch on, who knows? Not to be outdone by React v19.2 last week, Next.js 16 beta d...

It’s been a big week for React devs as the annual React Conf just wrapped up in Las Vegas. The biggest news? React and React Native are moving out from under Meta to a new React Foundation with an independent technical governance structure. The React Foundation’s mission will be to support the React community and ecosystem, and a board of directors will steer it going forward. Also in time for React Conf, React 19.2 dropped, and it brings new features like partial pre-rendering, a new u...

Anthropic dropped a bunch of good Claude Code updates. There’s a new a native VS Code extension, a v2 of the terminal version of Claude, code checkpoints, and it’s all powered by Sonnet 4.5, Anthropic’s best coding model yet. On top of Claude’s glow up, the Google Chrome team launched a Chrome DevTools MCP. AI coding assistants will be able to debug web pages directly in a Chrome browser, including using DevTools to review network requests, console output and page structure, simulate user int...

The supply chain attacks on npm continue and this week, Crowdstrike’s npm packages fell victim to the “Shai-Hulud” worm. To mitigate the potential of downloading these malicious packages, consider pinning specific package versions in JS projects and using 2FA to publish new package versions to npm. Also this week, WebAssembly Specification (Wasm) released v3.0. This version dramatically expands the memory Wasm apps can use, supports multiple memory usage, and now allows garbage collecti...

Last episode, we lamented Claude’s lack of checkpoints to roll back code when it goes off the rails. Other devs feel the same, and this week Checkpoints for Claude Code debuted. It’s an MCP server that follows Claude Code, creating checkpoints when tasks are completed, allowing for easy reverts when needed. The Bun team quietly pushed some nice new features in Bun v1.2. Highlights include: a unified SQL client with zero dependencies, native YAML file support, OS native credential storage for ...

The latest craze for MCP this week? Instead of multiple MCP servers with different tools, use an MCP server that accepts programming code as tool inputs - a single “ubertool” if you will. AI agents like Claude Code are pretty good at writing code, but letting the agent write and execute code to invoke API functions instead of using a defined MCP server doesn’t seem like the most efficient use of LLM tokens, but it's another approach to consider. In infrastructure news, there’s a library calle...

You just can’t keep TanStack out of the news for more than a few weeks before a new product appears. This week, it’s TanStack Devtools, which provides a centralized devtools panel of all the Tanstack libraries for streamlined DX and custom devtools support. The State of CSS 2025 survey results are in, and highlights include: devs love the new `:has()` feature, Tailwind CSS continues to be the most popular CSS framework, and over 60% of respondents are still using Sass or SCSS in their web app...

There’s drama brewing between AI-answer engine company Perplexity and hosting platform Cloudflare, which recently declared it would actively block AI bots from crawling websites without the owners’ permission. Cloudflare received complaints, set up its own test sites, and then asked Perplexity pointed questions only - and got answers! Not a great look, Perplexity. Two years after Vercel launched v1 of its AI SDK, it has dropped v5, and it’s got some major improvements. Rebuilt chat hooks, imp...

GitHub is advocating for a European Union Sovereign Tech Fund to help pay the open source software developers building and maintaining software relied upon by economies and societies just like any other necessary infrastructure like roads and bridges. Apple gets called out by the Open Web Advocacy group saying its technical rules and restrictions are blocking other browser vendors from successfully offering their own search engines to iOS users in the EU. Last episode we talked about Amazon’s...

There are so many headlines about AI IDE Windsurf as of late, but we’ll try to catch you up. First, OpenAI wanted to buy Windsurf for $3B, but the deal fell through due to Microsoft. Next, Google hired Windsurf’s top execs and researchers to work on its AI products, but didn’t buy the Windsurf IDE, for $2.4B. Then, Cognition bought the remainder of Windsurf’s IP (and its staff) to integrate into its own products like Devin. And did we mention this all happened in the span of 72 hours? A...

Tech companies continue the acquisition spree of the summer when Vercel announces it’s hired the creators of NuxtLabs, the folks who build metaframework Nuxt and server runtime Nitro. Figma returns to the newscycle with the introduction of its Dev Mode MCP server. This server allows agentic coding tools to pull in design context directly from Figma designs. Think: getting code, image, or variable context for a specific design selection or even porting over Figma designs directly into a code b...

The big tech company conferences continued this summer with Vercel hosting Vercel Ship 2025. As you’d expect there was lots of talk about AI and Vercel’s AI Cloud: tools, infrastructure, and platform enhancements to build AI agents and help AI agents use Vercel. On July 1, hosting platform Cloudflare declared Content Independence Day, and changed its settings to block AI crawlers by default unless they pay creators for their content. While we absolutely support this move, Cloudflare’s future ...
