slcl

slcl is a simple and lightweight “cloud storage” web file server focused on portability, minimalism, and efficiency. It provides a private, authenticated directory for uploads and a separate read-only public sharing area, aiming to be a low-resource alternative to heavier file platforms.

Key Features

• Private user area with authentication, file uploads, and configurable per-user quota
• Read-only public file sharing via a dedicated public directory (implemented with symlinks)
• Download folders as ZIP archives
• No client-side JavaScript requirement
• Stateless authentication using signed JSON Web Tokens (no server-side session storage)
• Optional thumbnail support via an external helper process using a named pipe

Use Cases

• Lightweight personal or family “Dropbox-like” web file access on low-end hardware
• Simple authenticated upload portal with quotas for small teams or labs
• Public distribution of selected files with a separate read-only share area

Limitations and Considerations

• TLS is intentionally not implemented; it must be provided by a reverse proxy
• Uploads are not end-to-end encrypted; encryption must be done before uploading if needed

slcl is a good fit when you want a small, fast, and simple web file server with basic sharing and uploads, without the overhead of full collaboration suites. It is especially suitable for environments where resource usage, simplicity, and minimal dependencies matter most.
