About TUS

tus is an open protocol built as a layer on top of the HTTP protocol, designed to enable resumable file uploads. This means that uploads can be paused and resumed at any time, even after network interruptions or browser crashes, without losing progress. It is easily integrated into existing applications, leveraging standard HTTP infrastructure like libraries, proxies, and firewalls, and can be used directly from any website. The protocol is production-ready, having been refined with feedback from companies like Vimeo and Google. It emphasizes simplicity, allowing for fast development and iteration. While the core specification is minimal, tus offers a range of extensions for additional functionality such as parallel uploading, checksums, and expiration, which can be implemented based on specific needs. The entire protocol, its implementations, and website are open-source under the MIT license, encouraging community contributions and an open evolution of the standard. tus is ideal for developers and organizations that need robust and reliable file upload capabilities, especially for large files or in environments with unreliable network conditions. Its open-source nature and adherence to HTTP standards make it a flexible and widely adoptable solution for ensuring data integrity during transfers.
