Krypton - Downloads

macOS and Linux 2.4.4 assets live on the 2.4.4 GitHub release page. Windows and editor downloads still use the 2.3.0 release page.

Platform versions

macOS arm64: 2.4.4 — newest release, includes kweb.app and Homebrew support.
Windows x86-64: 2.3.0 — current Windows installer until Forge's next Windows artifact lands.
Linux x86-64: 2.4.4 — current Linux tarball, rebuilt in QEMU with native seeds.
VS Code / Antigravity extension: 2.3.0.

What's in the release

krypton-2.4.4-macos-arm64.pkg — macOS Apple Silicon installer. Includes kcc, kweb, kweb.app, Choc, Objective-K helpers, and the 2.4.4 frontend.
krypton-2.4.4-macos-arm64.tar.gz — macOS Apple Silicon tarball, same contents as the .pkg.
krypton-2.4.4-linux-x86_64.tar.gz — Linux x86-64 self-contained tarball. Includes rebuilt 2.4.4 driver/frontend seeds and native kweb.
krypton-2.3.0-windows-x86_64.exe — Windows installer. Bundles kcc (Krypton-native driver), kcc-bin (the compile.k-built backend), kr (KryptScript runner with REPL), krypton_rt.dll, the WASM backend, kweb, and .k / .ks file associations.
krypton-language-2.3.0.vsix — VS Code / Antigravity extension. Adds .ks (KryptScript) + .k syntax and ships the kls language server for Windows + macOS.

Windows x86-64

One-click installer to C:\krypton with automatic PATH configuration. 2.7 MB. Windows 10 / 11 x64.

Download Windows installer

Or from source (no admin)

git clone https://github.com/t3m3d/krypton
cd krypton
bootstrap.bat        :: copies prebuilt seeds into place, no gcc needed
kcc --version        :: -> kcc version 2.3.0

Then add the repo root to your PATH, or use the from-source seed in place. bootstrap.bat ships the Krypton-native driver, the backend, kr.exe, and the runtime DLL — no C compiler, no clang.

macOS Apple Silicon (arm64)

Two install paths, both clang-free. The toolchain self-hosts on Mach-O without any external compiler. The kweb GUI is bundled as kweb.app.

Homebrew (recommended)

brew install t3m3d/krypton/krypton
kcc --version        # -> kcc version 2.4.4
kweb-gui             # opens kweb.app

Tap t3m3d/krypton is live; the formula installs the 2.4.4 macOS toolchain and a kweb-gui launcher.

Or the signed `.pkg` / tarball

Download .pkg or grab the tarball

Both install scripts ad-hoc-sign the binaries (AMFI) and clear download quarantine, so they run with no unidentified developer prompt.

Linux x86-64

Self-contained tarball, no clone or C compiler required:

tar xzf krypton-2.4.4-linux-x86_64.tar.gz
cd krypton-2.4.4-linux-x86_64
./install.sh         # symlinks kcc into /usr/local/bin (prompts for sudo if needed)
kcc --version        # -> kcc version 2.4.4
kcc hello.k -o hello && ./hello

Custom location: ./install.sh /opt/krypton, then add /opt/krypton/bin to PATH. Uninstall: rm /usr/local/bin/kcc plus the install dir.

Download Linux tarball

aarch64 (cross-compile target)

Linux aarch64 ships as a cross target in 2.4.4, not a native install. On an x86-64 box:

kcc --aarch64 prog.k -o prog   # static aarch64 ELF
qemu-aarch64-static prog       # or run on real arm64 hardware

Native aarch64-hosted toolchain is roadmap for the next release.

Or build from source (any Linux distro)

git clone https://github.com/t3m3d/krypton
cd krypton
./build.sh

Prebuilt seeds eliminate the need for external compilers — no gcc / clang at user-invocation time.

VS Code & Google Antigravity Extension (2.3.0)

Syntax highlighting, bracket matching, code folding, and kls-powered diagnostics + completions for Krypton (.k libraries) and KryptScript (.ks scripts). One .vsix installs in both VS Code and Google Antigravity (a VS Code fork) — Extensions panel � Install from VSIX.

Download .vsix

Krypton Web Framework (kweb)

kweb is a single-binary CLI that scaffolds, builds, serves, and deploys Krypton sites. The DSL stack:

htmk — HTML builder written in Krypton (every tag a function).
kcss — CSS DSL with theme tokens and breakpoints.
ks — server-side templating helpers.
server + router — HTTP server and route table for serving the output.

Bundled inside the Windows installer at C:\krypton\kweb.exe, Linux 2.4.4 as native kweb, and macOS 2.4.4 as kweb plus kweb.app. CLI surface:

kweb init       # scaffold a new site
kweb build            # render to dist/
kweb serve [port]     # local dev server
kweb deploy     # deploy dist/

On Linux, build from source after installing the toolchain:

git clone https://github.com/t3m3d/krypton
cd krypton/web
kcc kweb.htk -o kweb

This very site (krypton-lang.org) is rendered by kweb, written in Krypton.

Verify

After install, confirm the toolchain version:

kcc --version    # kcc version 2.4.4 on macOS/Linux, 2.3.0 on Windows

And confirm the editor extension version inside VS Code / Antigravity:

Extensions panel � Krypton � v2.3.0
