Open-source IT tools
Start with ownership: where the software runs, who patches it, how you recover it and whether the license covers the features your environment needs. This collection helps technical teams identify open-source candidates without treating a public repository as proof of production readiness.
For developers, platform engineers, SREs, sysadmins and security teams evaluating software they may need to operate themselves.
The decision to make
Shortlist by workload and failure mode first. Then compare release cadence, upgrade path, observability, backup support, authentication and the availability of commercial support.
