Compiling the compiler
Fresh-process median through C emission. Node.js runs the same prepared source as a reference; C compilation and linking are excluded.

The honest alpha
What it is.
What it isn’t.
Current capabilities and current limits.
It can do this.
-
01
Produce native executables
Compile JavaScript and erasable TypeScript into standalone programs.
-
02
Shape the runtime per build
Select eval, Realms, RegExp, Temporal, Intl, web, and curated Node.js APIs.
-
03
Carry application assets
Embed files or directories directly in the executable.
-
04
Compile at runtime—when selected
Eval-enabled builds embed the compiler; eval-free builds leave it out.
-
05
Run most of Test262
More than fifty thousand tests pass in the combined compiled baseline.
Not yet.
-
01
Battle-tested software
Real project use has only just started and is exposing rough edges.
-
02
Drop-in Node.js compatibility
The Node.js surface is intentionally curated, not complete.
-
03
Uniformly competitive speed
Some paths are quick; ordinary constructs can still be much slower.
-
04
Broad release support
Packages cover macOS and Linux on arm64 and x64; Windows and signed or notarized builds are not available yet.
Dogfooding
This page is the example.
This HTML is embedded in a native Linux executable and served from a Cloudflare Container.
