-RustFS is a high-performance distributed object storage software built using Rust, one of the most popular languages worldwide. Along with MinIO, it shares a range of advantages such as simplicity, S3 compatibility, open-source nature, support for data lakes, AI, and big data. Furthermore, it has a better and more user-friendly open-source license in comparison to other storage systems, being constructed under the Apache license. As Rust serves as its foundation, RustFS provides faster speed and safer distributed features for high-performance object storage.

-| Licensed under Apache, more business-friendly  | AGPL V3 License and other License, polluted open source and License traps, infringement of intellectual property rights |
-| Comprehensive S3 support, works with domestic and international cloud providers  | Full support for S3, but no local cloud vendor support |
-| Rust-based development, strong support for secure and innovative devices  | Poor support for edge gateways and secure innovative devices|
-| Stable commercial prices, free community support | High pricing, with costs up to $250,000 for 1PiB |
-| No risk | Intellectual property risks and risks of prohibited uses |
