Zipline

A ShareX/file upload server that is easy to use, packed with features, and with an easy setup!

Alternative to: imgur, cloudapp, sharex, gyazo

Zipline is a fast, self-hosted file, image, and media sharing server with a full web dashboard, built as a modern alternative to ShareX's default hosted upload targets. It supports chunked/partial uploads, folders, tags, URL shortening, image compression, and video thumbnails, and can store files on the local filesystem or S3-compatible storage. It also offers OAuth2, two-factor authentication, passkeys, password-protected links, and Discord/HTTP webhooks for automation.

Zipline Docker Compose example

Self-host Zipline on your own server, homelab, or VPS starting from this Docker Compose example. It runs Zipline in Docker containers using the official postgres:16, ghcr.io/diced/zipline:latest images, with persistent volumes and automatic restarts preconfigured. Review the environment variables and adjust them to your setup, save the file as compose.yml (or docker-compose.yml), and start the stack with docker compose up -d.

  postgresql:
    image: postgres:16
