My tool of the day - webcontainers.io

happy to finally announce it! @cloudflare.social is now backing @pkg.pr.new's data infrastructure! thank you so much everyone for supporting the tool and making this possible.

PGlite can now be used with any Postgres client, and pairs perfectly with AI app builders for vibe coding. Love that with @bolt.new *everything* runs in the browser - node, the dev server, and now even PGlite 🚀🤯 Awesome job by the team to get this out!

AST based V8 code coverage is finally here! I thought of this feature first time over 2 years ago, but knew it would require so much work that I couldn't finish it by working on Vitest just on weekends. Ever since @stackblitz.com hired me to work on Vitest I knew I could finish features like this.

I think @bolt.new already has excellent nuxt + vue support - you can already get it to build a nuxt project for you! 💪 @v0.dev says it supports vue, though it could be better. (I'd love to help the team there add nuxt support btw) roe.dev/ama #ama

having 57 contributors on @pkg.pr.new looks really good ngl!

@bolt.new are looking for an engineer to advance web computing by working on WebContainer, the first in-browser WebAssembly-based operating system. You'd be getting paid to be an Open Source contributor, AND you'd get to work with @patak.dev. Sounds pretty good to us! opensourcepledge.com/jobs/

Appreciate @bolt.new partnering with us on the revamp of the Secret Sauce podcast and excited to share this recent story where I vibed this founder's startup in 90mins. Since we recorded this pilot, he's done the following: ✅ Secured Funding ✅ Sold first customer youtu.be/lRs_ilB4giQ

@rescript-lang.org has officially adopted @pkg.pr.new, which means we now have npm packages for every commit 🚀 No more npm link or waiting for an alpha release! Thank you @aslemammad.bsky.social, @amirsakhravi.bsky.social and the @stackblitz.com team for supporting the ecosystem.

Hey @bolt.new let's shoot some hoops with @solidjs.com while breaking down the @nba.com Playoffs 2025 🏀

Rspack 1.4 will introduce Wasm build, allowing browser-based bundling in StackBlitz and other web environments. We have successfully run several cases and are actively working on remaining edge cases. Special thanks to cpunisher and Brooooook_lyn for making this possible❤️

Introducing native Stripe integration for Bolt You can now go from idea to building your entire SaaS business inside Bolt — no coding necessary. Sell products, offer subscriptions & get paid faster than ever before.

Node 20 has just landed in WebContainers! This unlocks the latest toolchains, faster builds, and new capabilities for all Bolt projects.

Finalizing rewrite of AST-aware v8-to-istanbul. This will provide accuracy of Istanbul coverage for V8 coverage reports. I've intentionally kept this tool unopinionated so that it's not strictly tied to just @vitest.dev - it should be usable with Jest, C8, Playwright and node:test too.

Finally got oxc-parser to work on stackblitz. stackblitz.com/edit/oxc-par...

Still kind of buggy I got MPC servers running entirely sandboxed in the browser with @stackblitz.com webcontainers blamy.github.io/wmcp-react/?path=/story/mcp-chat--example

After organizing three ViteConf online editions hosted by us at @stackblitz.com, this year ViteConf will be in-person! Just got back home from Amsterdam where we announced it in the Theater stage with Jos and Evan. JS World conferences are incredible, this one will be amazing! See y'all on October 🙌

Did you ever wonder what *exactly* @vite.dev is? Why it is fast, or why Rollup *and* ESBuild are both used? The one and only @patak.dev answers all these and more questions on the latest episode together with @thealexlichter.com! No matter which framework you use, this is relevant to all of you

Introducing Figma to Bolt Go from Figma to pixel-perfect full stack app — just put bolt․new in front of the URL & start prompting!

Thank God we have @stackblitz.com. It has never been so easy to get issue reproductions from users 🙌... when they provide one. Btw being able to go to stackblitz.com/github/owner... so we don't have to clone a repo is such a nice feature

🕳️ node-modules.dev v0.4.0 is just out! ⚠️ Deprecated packages 🌈 Clusters by @pnpm.io catalogs 🔼 Latest version indicator 📖 publint.dev integration Thanks @jyc.dev @43081j.com @bluwy.me @sxzz.dev et al. for the PRs, brainstorming, and tools! 💚 We should really take some actions to cleanup now! 🧹

I wanted to see all the metadata for a Bluesky post and the easiest way to do it was ask @bolt.new to make me a web app to do it. Literally quicker than going to the docs and manually hitting the API. What times we live in. Anyway, here it is: bluesky-post-viewer.netlify.app

Heads-up: Advanced Debugging is rolling out 🛠️ We’ve been working on a new debugging experience—one that’s smarter, more accurate, and reduces token usage up to 90% (!) Here’s how it works 👇

Bolt 🔗 Supabase integration just leveled up! → Connect to an existing Supabase project → Pause & Resume projects from Bolt → Use same DB for multiple mobile/web apps → Disconnect when needed What should we add next? 👀

Also, @stackblitz.com's WebContainers have been a promising way to run Expo CLI and the dev server in the web browser, making the Expo framework more accessible to browser-using agents like OpenAI's Operator.
