Introducing SWC Next: the foundation for SWC’s next major version, built on a new architecture inspired by Yuku.
- Up to 3x faster native parsing
- Up to 10x faster parsing through the JavaScript API
- A flat, ESTree-based AST designed for speed, memory efficiency, and JavaScript extensibility
Starting with parsing, we’re bringing the rest of SWC to this new architecture.
Built together by the SWC and Rstack teams.

I'm excited to share that @RomeAILab is now open source!
We believe the next step for agents isn't just better models — it's better primitives: tools, memory, workflows, apps, and interfaces that agents can compose, build, and continuously improve with you.
We'll keep building RomeOS in public, and we'd love to see you join the community.
github.com/rome-os/rome
Awesome!
I’ve been building Rome for the past four months, since leaving @rspack_dev.
I genuinely love this product and this team. Yunfan, one of my best friends, is also the founder of the company, which makes this journey even more special.
Follow us — we’ll keep sharing the fun, weird, and interesting things we learn while building and running an agent company.

Fast declarations for monorepos⚡️
Rslib isolated declarations make `rslib build` daily type emits much faster, while `rslint --type-check` keeps full validation where you need it, such as CI.
Less waiting in builds. Same type safety gate.

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

❓Did you know you can write “in-source tests” in JavaScript
Rstest supports in-source tests — write your test right next to the code. Test code is stripped in production builds. Zero bundle cost. ⚡️
Rust-style DX, now in your JS toolchain 🦀

📉 devServer: 192 deps → 1
And new stuff hits hard:
🧩 Pure ESM core, modern ESM library output
⚛️ Experimental RSC support
...
Lean, Fast, Modern Web Bundling 🚀
🚀 Rslib `v0.21.0` is out!
- Support using Node.js Single Executable Application to package the generated JS output into an executable file
- Provide a `rslib-best-practices` skill, which can optionally be installed during project creation
Release notes: github.com/web-infra-dev/rsl…
MCP Apps lets AI hosts render interactive UI in conversations. But most solutions bundle UI into the MCP Server — rebuild + redeploy every time anything changes.
We built @module-federation/mcp-apps: point a JSON at your existing MF remotes, and your components show up in Claude. Zero separate builds.
