Best alternatives to ZeroFS in 2026
Cloud object storage like S3 is cheap and durable, but it doesn't behave like a normal disk — you can't just open a folder in it, mount it, or point a regular application at it the way you would local storage. ZeroFS closes that gap: it takes S3-compatible storage and makes it look and behave like an actual filesystem or hard drive to your operating system, so tools and applications that expect regular files or a mounted disk just work, while your data actually lives in cheap, durable object storage behind the scenes. Technically, it exposes storage through multiple protocols — NFS and 9P for POSIX-compliant filesystem access, and NBD for raw block device access — all running from a single userspace process with no external database dependency. Every file is encrypted with XChaCha20-Poly1305 before it's compressed (zstd or lz4) and uploaded, and it includes local caching across memory and disk tiers, geo-distributed mirroring across multiple S3 regions, read replicas, checkpoint functionality, and TRIM support so deleted space actually gets reclaimed rather than sitting unused. It's built to deliver near-raw-S3 throughput for large files while also scaling to hundreds of millions of small files, which is where naive S3-as-a-filesystem approaches usually fall apart. It's open source under GNU AGPL v3, with a commercial license available for organizations that need one, though commercial pricing isn't publicly listed.
