Cimian
What Cimian is
Cimian is an open-source system for automating Windows software installations from a web server-based repository of packages and metadata. It can deploy, update, and remove software, including through zero-touch bootstrap provisioning. Supported package types include MSI, MSIX, EXE, PowerShell scripts, and NuGet .nupkg files. Administrators configure settings, manifests, catalogs, and package metadata in YAML. Users can browse, install, update, and remove optional software through the WinUI 3 Managed Software Center without admin rights. Conditional deployment rules can select software based on machine details such as hostname, architecture, operating system version, or domain. Cimian supports Windows x64 and ARM64 and is built with C# and .NET 10. The project describes integrations with Microsoft Intune and cloud storage such as AWS S3 and Azure Blob Storage. Its README lists security features including TLS for repository communications, package signature validation, PowerShell signing, and audit logging. Cimian is distributed under the MIT License and is free to use. The latest release is provided unsigned, with instructions to sign binaries and MSI installers using an organization's certificate.
