updatekezel

updatekezel is a Hungarian-developed software utility designed to streamline the management of application updates across Windows and Linux operating systems. The tool functions as a centralized update server and a lightweight client that can be integrated into existing deployment pipelines or used as a standalone service. Its architecture follows a client–server model, where the updatekezel server hosts update packages, metadata, and integrity checks, while clients discover and retrieve updates over HTTP or HTTPS. The system supports delta updates, allowing clients to download only changed parts of files, thereby reducing bandwidth consumption. Authentication and authorization are managed through TLS certificates and optional OAuth integration, ensuring secure distribution of sensitive updates.

Key features of updatekezel include support for multiple artifact formats (such as MSI, EXE, and compressed tarballs), granular version control with semantically versioned tags, and rollback capabilities that enable administrators to revert to previous stable releases in case of deployment failures. The utility provides a simple command‑line interface for manual update checks and an optional GUI for monitoring update status and logs. It also exposes a RESTful API that can be invoked by automation tools like Ansible, Puppet, or custom scripts, making it suitable for DevOps workflows.

The project is released under the MIT license, encouraging community contributions and forkability. Its documentation covers installation procedures, configuration options, and troubleshooting steps and is maintained alongside a public issue tracker on GitHub. Because of its open nature, updatekezel can be adapted to enterprise environments that require strict compliance with internal security policies, yet desire the flexibility of an open‑source solution for update distribution.
