A high-performance, S3-compatible distributed object storage system built in Rust, optimized for data lakes and AI workloads.
RustFS is an open-source, high-performance distributed object storage system built in the Rust programming language. It is fully compatible with the Amazon S3 API, allowing it to serve as a drop-in replacement for other S3-compatible storage platforms. It is specifically optimized for data lakes, AI, and big data workloads, offering superior performance and a permissive license.
Developers and organizations needing a performant, self-hosted object storage solution for applications like AI model training, data analytics platforms, or as a private cloud storage backend. It's ideal for those concerned with data sovereignty, licensing freedom, and edge computing.
Developers choose RustFS for its benchmarked performance advantages over alternatives like MinIO, its memory-safe Rust foundation, and its permissive Apache 2.0 license that avoids the restrictions of AGPL. It provides enterprise-grade features with a strong focus on compliance and data control.
🚀2.3x faster than MinIO for 4KB object payloads. RustFS is an open-source, S3-compatible high-performance object storage system supporting migration and coexistence with other S3-compatible platforms such as MinIO and Ceph.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
RustFS is benchmarked as faster than MinIO for small object payloads, leveraging Rust's efficiency for high-throughput AI and data lake workloads.
Offers full S3 compatibility and native OpenStack Swift API support with Keystone authentication, ensuring seamless integration with existing tools and clouds.
Licensed under Apache 2.0, it avoids AGPL restrictions, making it safe for commercial use and encouraging contributions without licensing risks.
Designed with no telemetry and compliance with GDPR, CCPA, and APPI, preventing unauthorized data egress for regulated or privacy-focused deployments.
Key functionalities like distributed mode, lifecycle management, and RustFS KMS are marked as under testing or partial in the status table, limiting immediate production readiness.
Docker deployment requires manually changing directory ownership to UID 10001, adding complexity and potential for permission errors compared to more automated solutions.
As a newer project, it lacks the extensive third-party integrations, plugins, and community support of established players like MinIO, which may affect troubleshooting and scalability.
RustFS is an open-source alternative to the following products:
MinIO is a high-performance, S3-compatible object storage server designed for cloud-native applications, offering scalable and distributed storage for unstructured data.
Ceph is an open-source, distributed storage platform that provides object, block, and file storage in a single unified system, designed for scalability and reliability.
