MinIO is an open-source, high-performance object storage system that’s fully compatible with the Amazon S3 API. Written in Go, it’s designed to handle unstructured data like photos, videos, log files, backups, and container images. MinIO can run on bare metal, Kubernetes, or any cloud environment.
The project has become one of the most popular open-source storage solutions on GitHub, with thousands of stars and a massive community. MinIO’s architecture is built for speed — it can deliver read/write throughput of hundreds of gigabytes per second on standard hardware.
MinIO is particularly popular in AI and machine learning pipelines where teams need fast, S3-compatible storage that they can run in their own data centers. Companies like Samsung, Uber, and Nutanix use MinIO in production. The software supports erasure coding, bitrot protection, encryption, and identity management.
The company behind MinIO offers an enterprise subscription with additional features like a management console, extended support, and compliance certifications. MinIO’s licensing uses GNU AGPL v3 for the open-source version, while commercial licenses are available for enterprises that need them.
