I have a pretty clear idea of what AI-based orchestration should look like, but if you could let me know what features you’d like to see in the AI tool, I’d be happy to incorporate them.

Rust React Compiler is merged!
We tested it at @vercel on sites like v0:
SWC plugin had a long WASM cold start, but great wins over the OG Compiler.
Linking the code directly into Turbopack is even better: >40% faster compilation.
PRs coming soon to get this in Next.js 16.4

We've been using Matt's 𝚜𝚌𝚊𝚝𝚝𝚎𝚛𝚎𝚍-𝚌𝚘𝚕𝚕𝚎𝚌𝚝 and 𝚌𝚝𝚘𝚛 Rust crates in Turbopack to intern strings and register serialization functions. If that sort of thing interests you, I highly recommend reading his blog post! grack.com/blog/2026/06/11/li…

I just finished up my post on "pre-main", linker-assisted initialization in Rust: Linker Sections, Constructors, and Distributed Registration.
There's life before main in Rust (and it's an extremely useful place to do work):

We’re building a new Rust-based compiler & optimizer for TypeScript, using static type info from typescript-go. Think Google Closure Compiler for TS: smaller/faster apps & libs, targeting ~10–20% bundle size reduction. It’s still private, but we plan to open source it.

Rstest was nominated for this year's Productivity Booster award at JSNation 🎉
Here's the video shown on stage, made by @fi3ework27 with @Remotion (which is also powered by Rspack)

Rspack keeps pushing forward with support for the latest language features.
After `import defer`, we're now adding `import source` for Wasm, following the TC39 Source Phase Imports proposal. It lets you import a compiled Wasm module directly.
Thanks to @magic_akari for the contribution!

Rspack tsgo cut overall build time by 60% in our benchmark 🚀
Type checking during builds is often one of the biggest build-time costs.
tsgo integration is now available out of the box in:
- Rspack plugin
- Rsbuild plugin
- Rslib

I've been working on Parcel v3 recently! It has a completely different architecture than every other tool out there. It's a totally standalone native binary with no dependency on Node, and supports native plugins written in any language (e.g. Rust, Go, Swift, Zig, C, etc.) for perf critical stuff, as well as a custom runtime for JS plugins. Over 50x faster than v2 in early benchmarks. I'll have more to share soon!

🎉 Big news: Node.js is changing its release schedule for the first time in 10 years.
From October 2026, less to remember and easier to know what's Current or LTS.
Here's everything you need to know 🧵👇

Given that Claude models tend to ignore instructions, using Claude to improve Claude could actually be quite risky.
Jun 4
Our internal data shows Claude is accelerating AI development—a possible path to recursive self-improvement, or AI autonomously building a more capable successor.
It’s happening faster than we thought, and the implications deserve greater attention. anthropic.com/institute/recu…

A small clarification: I fully understand the role that @swc_rs plays in the Rust ecosystem, and I have absolutely no intention of rewriting “SWC.”
This is an idea for a new project.
Mar 4
I found that I can reimplement the whole SWC with AI…
Not 100% sure if it will really work and not sure if I want it, but at least I can now prove my theories.
Time for competition?

VoidZero is joining Cloudflare.
Our mission stays the same: to make JavaScript developers more productive than ever before. Vite, Vitest, Rolldown, Oxc, and Vite remain MIT-licensed. Evan and the VoidZero team will continue leading them.
Cloudflare shares our commitment to open source. Together, we can keep investing in the tooling developers rely on every day, while bringing the Vite ecosystem and Cloudflare’s platform even closer together.

the biggest problem is that most people in this space talking about model's performance were not good programmers to begin with and don't even know what good is.

I’m tired of useless AI benchmarks. How about we give three people a different model, strand them on an island, and see who survives the longest

It took me just an hour to swap Webpack with Rspack in @wordpress/scripts and plugin build time reduced from ~7s to ~1.2s.

"I use it every day and honestly can't live without it. Saves me tons of time."
@hardfist_1, lead of @rspack_dev at ByteDance, on the CodSpeed Wizard.
So proud and excited to build the performance agent for the fastest projects on the planet!

🌲Rspack's tree shaking just got smarter 🦀
Two recent optimizations remove more unused code:
1. Inlined booleans can make branch-local dependencies inactive
2. Namespace default re-exports now preserve property-level usage
More precise bundles, less dead code
