New from Vercel Labs: tsc-ts
TypeScript was written in TypeScript
Then rewritten in Go
We ported it back to TypeScript
Compiled it with scriptc
And it's 2-4x faster than tsgo

AI will make most infrastructure natively optimized. Case in point: fx can literally finish tasks faster than other agents can boot.

Introducing fx, a tiny, open, native coding agent from Vercel Labs.
Originally an internal tool, fx is a harness and CLI written in Zig, optimized for research and embedding in larger systems. Today, we're open sourcing it.
fx is built on three principles:
1. Fast. A single native binary, no runtime to install. It cold starts in 10Β΅s and does no unnecessary work or I/O before accepting input. fx is the answer to "how fast can a coding agent be?"
2. Light. The 6.3MiB binary uses single-digit megabytes of memory at baseline, made for instant installation and embedding in resource-constrained environments and agent sandboxes.
3. Open. Apache-2.0, model and provider agnostic, suitable for local and cloud inference. Its small core extends through skills, plugins, and MCP.
Minimalism is an obsession throughout the entire harness: system prompt, tools, features, binary. The goal was to keep context usage and time to first token low, and make fx optimal for model benchmarking, sandboxing, evals, and gyms.
You can use fx directly or embed it as infrastructure. The CLI feels more like a Unix shell than an IDE in the terminal: it preserves scroll history, produces minimal output, and uses complex TUI rendering very, very sparingly. Programmatically, ππ‘ πππ --ππππ gives structured output, ππ‘ πππ connects to editors and other clients, and WebAssembly can even run the whole thing inside the browser (see: fx.sh/try).
Privacy is a design constraint: no product telemetry, sessions and usage stay local, and no source code or prompts are shared with any endpoint other than inference. With local inference and auto-updates off, fx is fully hermetic.
fx is experimental. Use at your own risk and expect frequent changes. Chat with us on X (fx.sh/xchat) or file issues (fx.sh/issues).

TypeScript 7 Support in Next.js
TLDR:
You can now enable `experimental.useTypeScriptCli` to use TypeScript 7 on next@preview
Details:
TypeScript 7 released with ts-go, very excited about the speedup!
The release is (intentionally) missing the JavaScript API which they're aiming to release in TypeScript 7.1.
Unfortunately that meant that the TypeScript 7 release as-is breaks frameworks integrating TypeScript using the JS API.
Next.js uses the JS API to invoke TypeScript during "next build" and adds additional formatting so that the logs are consistent with other parts of the build.
In order to support TypeScript 7 without a JS API we had to change the way TypeScript is invoked to directly use the installed `tsc` command.
This change is available under experimental.useTypeScriptCli
It's released as part of the Next.js 16.3 Preview.
You can install it using `npm install next@preview`.
