## What it is
tusd is the official reference implementation of the tus resumable upload protocol, written in Go and distributed as a single binary. It accepts uploads of arbitrary size over HTTP, storing them on local disk, AWS S3, Google Cloud Storage, or Azure Blob Storage, and is extensible via script, HTTP, or gRPC hooks.

## Use cases
- handle resumable file uploads that survive network interruptions
- accept large video uploads without re-uploading after a pause
- self-host an upload server backed by S3
- add pause-and-resume upload support to a web app
- receive uploads from any tus-compatible client
- post-process uploaded files via hooks

## When to choose
- you need reliable resumable uploads over HTTP
- you want a standalone, dependency-free upload server binary
- you need pluggable cloud storage backends for uploads
- you want to embed resumable upload handling in a Go application

## When to avoid
- you only need simple non-resumable multipart uploads
- you need a managed upload service rather than self-hosting
- your stack requires a non-Go implementation with native integration

## Facets
- artifact type: service
- maturity: stable
- function: http-server, file-upload, web-framework
- domain: web-development, backend, files, apis
- platform: windows, go, self-hosted, cross-platform
