Kungfu UNGFU™Developer Platform

Back to libkungfu.devVersioned multi-product installer

Install a native CLI · no coding required

One installer. Choose the product and version you need.

Install KFD, Buildchain, Kungfu, or Agent Hub Demo on supported macOS, Linux, and Windows systems. With no product argument, both installers default to Kungfu; choose a product when you need another CLI, an exact historical version, or rollback.

https://libkungfu.dev/install.sh and https://libkungfu.dev/install.ps1 are the canonical public entries. They consume one reviewed Site catalog that projects exact product-owned GitHub Releases without becoming another release authority. KFD, Buildchain, Kungfu, and Agent Hub Demo differ only in how their release-owned packages and evidence are interpreted.

Prefer a package manager?

KFD, Buildchain, and Kungfu are also on Homebrew.

Use the official tap when you want Homebrew to own installation, upgrades, and removal. Use the versioned installer above when you need an exact catalogued release or rollback.

KFD

brew install kungfu-systems/tap/kfd

Buildchain

brew install kungfu-systems/tap/buildchain

Kungfu

brew install kungfu-systems/tap/kungfu

Homebrew owns package-manager installation, upgrades, and removal. The tap projects upstream release evidence and remains separate from this versioned installer.

Choose an exact version

Current is convenient. Exact is reproducible.

Pass --version when a project, receipt, or recovery needs a specific published release. Historical releases stay selectable while they remain in the reviewed catalog.

curl -fsSL https://libkungfu.dev/install.sh | sh -s -- buildchain --version 3.0.6
& ([scriptblock]::Create((irm https://libkungfu.dev/install.ps1))) buildchain -Version 3.0.6

Recover a managed installation

Roll back without guessing.

The installer keeps content-addressed versions and activates commands through bounded user-owned links. Rollback restores the previously managed activation.

curl -fsSL https://libkungfu.dev/install.sh | sh -s -- buildchain --rollback
& ([scriptblock]::Create((irm https://libkungfu.dev/install.ps1))) buildchain -Rollback
