Why Leil FS?
Truly Open
No “Business Source License” restrictions. GPL-3.0 means you can build, deploy, and profit freely. No vendor lock-in, no hidden limitations, permanently open.
Commercial Ready
Battle-tested in production at petabyte scale. Enterprise features: erasure coding, uRaft HA, CoW snapshots, NFSv4 ACLs — all included in the open-source core.
POSIX Reliable
Full POSIX compliance for seamless integration with Linux and Windows environments. No proprietary APIs. Standard filesystem semantics your applications already expect.
GPL-3.0 Freedom
Commercial-ready with no business restrictions. Fork it, ship it, profit from it—just keep it open. Any distributed modifications must also be shared under GPL-3.0.
POSIX Compliant
Seamlessly integrates with your existing Linux and Windows environments. Standard filesystem semantics.
Hyperscale Ready
Engineered to handle petabytes to exabytes with zero downtime. Chunk-based architecture inspired by Google File System.
Virtualization Ready
Native Proxmox plugin and Kubernetes Operator with CSI driver for seamless orchestration.
Universal Packaging
Apt-repo, Docker Hub (multi-arch), and RPM. Built for Debian, Ubuntu, Fedora, and RHEL/Rocky Linux.
Maker-Friendly
High-performance storage for self-hosters, storage enthusiasts and builders who want to experiment and deploy their own clusters. Join our Matrix community to connect directly with the engineers who write the code.
