In their own words
OpenEBS
OpenEBS is open-source Kubernetes storage software for developers and platform SREs deploying stateful workloads. It turns storage on Kubernetes worker nodes into local or distributed persistent volumes and operates in userspace rather than relying on Linux kernel-dependent software. Its engines include Replicated PV Mayastor and local volumes using Hostpath, LVM, ZFS, or experimental Rawfile. Mayastor can synchronously replicate volumes across Kubernetes zones. Kubernetes-native operations provide copy-on-write snapshots and clones, while Velero plugins support backup and restore to AWS S3, GCP Object Storage, or MinIO. Volumes expose metrics including IOPS, throughput, latency, and traffic patterns for Prometheus and Grafana. OpenEBS also exposes declarative APIs through Kubernetes custom resources and can be installed with Helm 3.2 or newer. Mayastor disk pools support data-at-rest encryption with user-defined AES-XTS keys. Listed use cases include self-managed databases, observability stacks, CI/CD, object storage, websites, and ML pipelines. Mayastor DiskPools are limited to one block device, and encryption keys cannot be rotated.
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.
