JuiceFS vs Tahoe-LAFS

JuiceFS is an open-source, cloud-native distributed file system that stores file data in object storage and metadata separately in a metadata engine. It supports POSIX, HDFS, S3, and WebDAV protocols, with storage options including Amazon S3, Google Cloud Storage, Azure Blob Storage, MinIO, Ceph, and HDFS. Documented uses include big data, machine learning, Kubernetes, shared workspaces, and backup. Integrations cover Kubernetes CSI and Hadoop ecosystem components such as Spark, Presto, Hive, Flink, Trino, and StarRocks. JuiceFS offers a self-hosted Community Edition, a managed Cloud Service, and an Enterprise Edition with on-premises, BYOC, and other deployment options. Its downloadable client supports Linux, macOS, and Windows; WSL 2 is recommended for Windows. Encryption in transit and at rest is supported, but at-rest encryption must be enabled when creating a file system and does not cover client-side cached data or file metadata. Community Edition is free; paid plans start at $0.02/mo.

Tahoe-LAFS is free, open-source software for storing files across multiple servers. Before upload, a client encrypts each file with a unique key. Erasure coding distributes each file as shares, allowing recovery when some storage servers fail; the documented default uses 10 shares across at least 7 servers and can recover from any 3. A gateway checks integrity and ignores corrupted shares. Files can be immutable or mutable, with read-only or read-write access for mutable files and directories. The gateway gives access through HTTP(S) and SFTP, and a REST-style Web API supports programmatic operations. Users can run a gateway or operate a full grid of storage nodes and an introducer. Installation is documented for Windows, macOS, Linux, and BSD. The software is available under GNU GPL version 2 or later, or the Transitive Grace Period Public Licence version 1.0 or later. It is free at free. The public test grid is for experimentation, not reliable or large-scale storage.
