Gokapi

Gokapi is a lightweight, self-hosted file sharing server designed for sharing files via expiring download links. It focuses on controlled uploads (no public upload) and supports encryption and optional S3-compatible storage for flexible deployments.

Key Features

• Expiring file shares based on time and/or number of downloads
• User management with role-based permissions; only registered users can upload
• Built-in encryption support, including end-to-end encrypted uploads
• File deduplication to reduce storage usage for identical uploads
• Optional storage backend support for AWS S3 and S3-compatible providers
• OpenID Connect (OIDC) authentication integration for SSO
• REST API for automation and integration
• Customizable web UI via custom CSS and JavaScript

Use Cases

• Secure one-off file delivery with automatic link and file expiration
• Internal team file drop for controlled sharing without public uploads
• Automated file distribution workflows using the REST API

Limitations and Considerations

• Designed for simple file sharing rather than full sync/collaboration (not a cloud drive)
• Some advanced features (S3 backends, SSO) require additional configuration

Gokapi is a strong choice when you need an easy-to-run, privacy-focused file sharing service with expiring links and modern authentication options. Its lightweight Go-based implementation and optional S3 storage make it suitable for both homelabs and small teams.
