tus Resumable Upload Protocol

The open protocol for resumable file uploads over HTTP, started by Transloadit in 2013 and stable at 1.0.0 since 2016 — a PATCH-based append model with Upload-Offset and Upload-Length headers, a creation extension, checksums, concatenation and expiration. Implemented in clients and servers for every major language and used in production by Cloudflare, Vimeo, Supabase and others, it is the community standard the IETF’s Resumable Uploads for HTTP draft grew out of.
