Alarik is a high-performance, self-hosted object storage system with an S3-compatible API.

The software is written in Swift and provides a web console for managing objects, buckets, users, access keys and storage nodes. It can run on a single server or scale horizontally across a cluster with erasure-coded storage.

This is free and open source software.

• Supports core S3 object operations including upload, download, copy, deletion and multi-object deletion.
• Offers multipart uploads with controls for creating, completing, aborting and listing uploads.
• Provides bucket versioning, delete markers and object version management.
• Supports conditional requests, range reads and presigned URLs using AWS Signature Version 4 authentication.
• Offers object tagging, bucket policies, lifecycle rules and public access controls.
• Includes a web console with an object browser, drag-and-drop uploads, recursive search and storage statistics.
• Lets users edit object metadata, manage versions and create time-limited public links.
• Supports local user accounts, multiple OpenID Connect identity providers and expiring S3 access keys.
• Provides persistent, HMAC-signed webhook notifications with filtering and automatic retries.
• Replicates objects to remote S3-compatible storage systems using configurable synchronous or asynchronous rules.
• Supports horizontal scaling with Reed-Solomon erasure coding, quorum writes and deterministic object placement.
• Offers read repair, bit-rot detection, background scrubbing and automatic shard reconstruction.
• Stores configuration and cluster metadata internally without requiring an external database.
• Provides an administrative dashboard for monitoring resources, traffic, storage distribution and cluster health.
