What is it?

Plik is a self-hosted system for sharing files temporarily, similar to WeTransfer. Users upload files through a Vue 3 web interface or the command line client, and receive a link to share with recipients. Uploads can expire after a configurable TTL and be set to delete after the first download.

The server stores file data on local disk, S3, OpenStack Swift or Google Cloud Storage, and keeps metadata in SQLite, PostgreSQL or MySQL. Authentication can use local accounts, Google, GitHub, OVH or OIDC, and uploads can be protected with BasicAuth. End-to-end encryption uses Age, with the CLI and web client able to decrypt each other's files.

Plik also offers a stream mode where nothing is stored, file preview with syntax highlighting, Markdown and Mermaid rendering, Prometheus metrics, and an MCP server for AI assistants. It can be deployed with Docker, a release binary, a Debian package or a Helm chart.
