Latest release: 2.3.0

Downloads

Krypton 2.3.0 ships native on Windows x86-64, macOS Apple Silicon, and Linux x86-64. Self-host fix across all three backends, new growing-capacity StringBuilder, and a Krypton-native CLI driver. Plus the 2.3.0 VS Code / Google Antigravity extension.

Released June 6, 2026. All assets live on one GitHub release page.

What's in the release

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.

Homebrew (recommended)

brew install t3m3d/krypton/krypton
kcc --version        # -> kcc version 2.3.0

Tap t3m3d/krypton is live; the formula installs the same 2.3.0 macOS toolchain.

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-2.3.0-linux-x86_64.tar.gz
cd krypton-2.3.0-linux-x86_64
./install.sh         # symlinks kcc into /usr/local/bin (prompts for sudo if needed)
kcc --version        # -> kcc version 2.3.0
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 2.3.0, 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:

Bundled inside the Windows installer at C:\krypton\kweb.exe. CLI surface:

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

On macOS / Linux, build from source after installing the toolchain:

git clone https://github.com/t3m3d/kweb
cd kweb
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 2.3.0

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

Extensions panel ’ Krypton ’ v2.3.0
