awesome-foss/awesome-sysadmin

Awesome Sysadmin is a community-maintained reference list of free and open-source tools for system administrators, DevOps engineers, and site reliability engineers. Think of it as a well-organized bookshelf of software recommendations, rather than building or running anything itself, it collects and categorizes hundreds of tools that professionals use to manage servers, networks, and infrastructure. The repository is organized into dozens of categories covering almost every aspect of running IT systems: automation and build tools, backup software, continuous integration pipelines, configuration management, databases, DNS management, identity and login systems, log aggregation, monitoring and alerting, networking, virtualization, VPNs, and more. Each entry includes a short description, license information, and a link to the project's source code or website, making it easy to compare options at a glance. This is not a software project you install or run, it is a curated knowledge resource. Someone would use it when evaluating tools for a new infrastructure setup, looking for open-source alternatives to expensive commercial products, or simply trying to discover what options exist in an unfamiliar category. For example, if you need a backup solution or a self-hosted monitoring stack, this list surfaces the established open-source options with just enough context to know where to look next. Because the list itself is just Markdown text, there is no runtime or programming language required to use it. Contributions come from the community via pull requests, and the repository uses a CI workflow to validate submissions.
