Best NAS Software in 2026
Updated
In short: TrueNAS is ranked #1 of 21 as of 4 October 2026, ahead of ZimaOS and napp-it. The best-ranked option with a free plan is ZimaOS.
A NAS setup can serve as shared storage and a platform for other workloads. To compare software for yours, look at storage pools, snapshots, user management and the app catalog, then check container support and virtual machines if you plan to use them. Cloud sync, free-plan availability and starting prices also help distinguish the options. ZimaOS and TrueNAS are among the opening entries, as is napp-it. Consider which capabilities match how you expect to organize and use storage; not every setup calls for the same mix of apps, containers or virtual machines. The ranking orders 21 options, with these features providing a basis for comparison.
21 NAS software ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
