Read Dominic's post.
(Here is mine from a while ago - aifoc.us/the-browser-is-the-…)
The browser is an amazingly powerful sandbox, hardened over decades to run unknown and risky code as safely as possible.

this. the battle against entropy is real and ongoing.

Rough week to run Node-based web apps.
WebContainers are the infinitely scalable secure sandbox for Node.js. Untrusted code runs isolated in the browser, away from your OS and your servers. Same tech powering @boltdotnew

⚠️ Node.js is vulnerable to remote code execution.
CVE-2026-111497 (high): A Node.js process that decompresses attacker-controlled Brotli data can be made to leak memory or run arbitrary code.
You’re exposed if your app or a library decompresses bad Brotli data (e.g. the built-in fetch(), body-parser)
Aikido detects this. Patches are available.

Looks like @SamVerschueren has a PR up here to migrate to WebContainer 👀

Today vibe coding goes pro.
Introducing Bolt v2:
→ World's best agents (Claude Code, Codex)
→ Built in backend (hosting, DB, storage, ...)
→ No error loops, no setup nightmares
Now anyone can build without boundaries.

🎉 NEWS! Tailwind v4 now works in WebContainer.
Huge kudos to @PhilippSpiess for this crazy quick turnaround, and also @Brooooook_lyn and @toyobayashi for their foundational work on napi-rs and emnapi which makes compiling native Node.js addons to WASM/WASI possible.
Lets go!
In Tailwind CSS v4.1.14 we've added an experimental WASM build of our native libraries, which means you can now use Tailwind CSS v4 in environments like StackBlitz ✨
Awesome work by @PhilippSpiess on this one and big thanks to @elmd_ for his help!
It was in beta for a bit to make sure we didn’t break anything, but now it’s the default for all projects 🔥🎉

🎉 BIG NEWS!
WebContainers now support Node.js 20.
With Node 20 you can now _require_ ESM 🤯 and do much more cool stuff!
Big shoutout to @SamVerschueren who's moved mountains to get WebContainers upgraded. Well done Sir! 👏
