Sysadmins, rejoice! If you’ve ever wasted hours digging through GitHub or forums for the right open-source tool to automate, monitor, or manage your infrastructure, awesome-sysadmin is about to become your new best friend. This curated list is a goldmine of free and open-source sysadmin resources—everything from backups to Kubernetes, LDAP to log management.

With over 30k GitHub stars and a community-driven approach, it’s not just a list—it’s a living, evolving toolkit. Whether you’re a seasoned sysadmin or just dipping your toes into infrastructure, this repo saves you the pain of trial-and-error tool hunting.

What It Does

awesome-sysadmin is a categorized, well-maintained collection of open-source sysadmin tools. It covers:

• Automation (Ansible, Terraform)
• Monitoring (Prometheus, Nagios)
• Cloud (OpenStack, Kubernetes)
• Databases, DNS, Logging, VPNs… and even niche categories like ChatOps and Service Discovery.

Each tool includes a direct link to its repo or homepage, so you’re one click away from docs or installation.

Why It’s Cool

1. No Fluff, Just Tools
   Unlike random blog lists, this repo is community-vetted. Tools are sorted by category, and submissions follow a strict PR template to avoid spam.

2. Pragmatic Curation
   It’s not just “popular” tools—lesser-known gems like Grafana (metrics) and NetBox (network automation) sit alongside classics like PostgreSQL and Nginx.

3. Sysadmin-First Focus
   Need a self-hosted PaaS? Check CapRover. Debugging network issues? Wireshark’s in there. The list respects the sysadmin’s workflow, not just trends.
