# Cubbit

> Cubbit is a European cloud storage provider offering DS3, a sovereign, geo-distributed, S3-compatible object storage platform. DS3 encrypts (AES-256), fragments, and replicates data across multiple user-selected European locations using Reed-Solomon erasure coding. It ships as DS3 Cloud (managed, geo-redundant, TBs to PBs) and DS3 Composer (self-hosted software-defined storage). The storage plane is AWS S3-compatible (endpoint https://s3.cubbit.eu, region eu-west-1, AWS Signature Version 4), so existing S3 SDKs and tools work unchanged.

## APIs
- [Cubbit DS3 S3-Compatible API](https://docs.cubbit.io/guides/s3-api): AWS S3-compatible object storage — buckets, objects, multipart upload, versioning, object lock (COMPLIANCE/GOVERNANCE + legal hold), object tagging. Base URL https://s3.cubbit.eu, region eu-west-1.
