MinIO

Description

MinIO is an S3-compatible object storage service for files, media, backups, and AI artifacts—self-hosted for performance and control.

Overview

Applications that speak “S3” (Pixelfed, Mastodon, Nextcloud, Flowise, etc.) store and retrieve objects from MinIO buckets using familiar SDKs and CLIs. Admins manage buckets, users, and access policies through a browser console while keeping everything on-prem.

Features

S3-compatible API for broad app compatibility
Buckets, users, access keys, and fine-grained policies
Optional versioning, lifecycle rules, and object lock
Presigned URLs for secure, time-limited uploads/downloads
Ideal for AI stacks: datasets, embeddings, and artifacts
