MinIO¶
High-performance S3-compatible object storage — now primarily the commercial AIStor platform after the open-source repo was archived.
Overview¶
MinIO was the leading open-source S3-compatible object storage. In February 2026, the open-source repository was archived and placed into maintenance mode. Active development continues under MinIO AIStor, a commercial platform designed for AI, analytics, and exascale workloads. Organizations using the archived OSS version should evaluate transition paths.
