Download
Download the weikio CLI for Linux and Windows, the agent installer for Windows Server and the images.env file that pins the Docker images of Weik.io 2026.2.2, published on 1 November 2026. The install scripts check the release's checksums before they install the CLI.
Install the CLI
$ curl -fsSL https://weik.io/install.sh | shirm https://weik.io/install.ps1 | iexOn Linux x64 the script installs ~/.local/bin/weikio after checking it against SHA256SUMS. On Windows x64 the PowerShell script installs the CLI without administrator rights.
On macOS the CLI is ready in the Try Weik.io dev container.
Pin a version
Set WEIKIO_CLI_VERSION to install one version. The Linux command needs curl and ca-certificates, which minimal images such as debian:12 don't have, so install them there first.
$ apt-get update && apt-get install -y curl ca-certificates
$ curl -fsSL https://weik.io/install.sh | WEIKIO_CLI_VERSION=2026.2.2 sh$env:WEIKIO_CLI_VERSION = '2026.2.2'; irm https://weik.io/install.ps1 | iexFiles
