In their own words
JuiceFS
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.
SeaweedFS
SeaweedFS is a distributed storage system that serves S3 objects, Iceberg tables, and POSIX files from one cluster. It supports S3, POSIX mounts, HDFS-compatible access, an Iceberg REST catalog, and WebDAV. Its built-in Iceberg catalog supports queries with Spark, Trino, Dremio, and DuckDB. The product describes scaling from gigabytes to petabytes and supporting billions of files. Development and testing under 25 TB are free, but production deployments require a paid license regardless of size. Monthly capacity licensing is $2 a month, based on used storage including replication or erasure-coding overhead; yearly licensing is $20 a year. Enterprise features include deleted-file recovery within a configurable retention window, point-in-time restoration, repair of missing or corrupted erasure-coding shards, and OIDC sign-in with role mapping. The free 25 TB trial limits deleted-file recovery retention to one hour. Enterprise support is optional and priced separately from capacity licensing. Community support is free and has no guaranteed response time. SeaweedFS is available for Linux, macOS, and Windows, with API access and self-hosted deployment.
