tuspyserver
A Python tus server implementation as a FastAPI router
Decision gist · record as of 2026-08-14
Yes. The package is actively maintained (released 1 day ago), has low install friction, zero known vulnerabilities, and solves a real problem—resumable uploads are non-trivial to implement correctly. The single fastapi dependency is lightweight, and the API is straightforward. The only caveat is that the license is unclear in the metadata, so verify the actual license in the repository before using in a commercial or copyleft context.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python>=3.8 and fastapi>=0.110.
- CORS headers must be exposed for chunked uploads to work correctly.
- Low friction: pure Python wheel with a single runtime dependency on fastapi>=0.110.

What it is and what it does
tuspyserver is a FastAPI router that adds resumable file upload capability to your application via the tus protocol. It handles the complexity of chunked uploads—allowing clients to pause and resume transfers—while managing metadata, expiration, and cleanup automatically. The router mounts directly into a FastAPI app and requires only fastapi>=0.110 and Python>=3.8.
You can customize behavior through optional hooks: validate uploads before they start (pre-create hook), run post-processing after completion (on_upload_complete), or inject dependencies to access your own services like databases or authentication. By default it stores files on the local filesystem, but you can swap in an S3 backend via the s3 extra. The package exposes a full HTTP API with upload, download, HEAD, DELETE, and OPTIONS endpoints, and handles the TUS protocol headers needed for resumable transfers.
Use it for
- Building a web app where users upload large files and need to resume if their connection drops.
- Validating file metadata or user permissions before accepting an upload via the pre-create hook.
- Logging completed uploads or triggering post-processing with the completion hook.
- Storing uploads directly to S3 instead of local disk to avoid coupling to a network filesystem.
- Implementing per-user upload quotas or directory routing via dependency injection.
