PicoShare

PicoShare is a minimalist, open-source service for uploading and sharing files. It provides direct download links for uploaded files, preserves original filenames and metadata, and avoids re-encoding or resizing media.

Key Features

• Direct download links for uploaded files, with no ads or required signups for recipients
• Supports arbitrary file types and sizes; no automatic re-encoding or resizing of media
• Simple admin interface protected by a shared secret for managing uploads and links
• Multiple deployment options: run from source or run an official container image
• Optional data replication support using a WAL-based replication tool for cloud backups
• Uses an embedded SQL database for file metadata and storage index to minimize operational complexity

Use Cases

• Quick one-off file sharing between collaborators without creating accounts
• Private media distribution where original file fidelity must be preserved (images, audio, video)
• Lightweight internal file drop service for small teams or personal servers

Limitations and Considerations

• Not designed for multi-writer clustered deployments: concurrent writes across multiple instances are not synchronized
• Maintained as a hobby/open-source project; scope is intentionally limited and some feature requests may be declined due to maintainer bandwidth
• For large-scale or enterprise use, additional monitoring, backup planning, and storage provisioning will be required

PicoShare is best suited where a simple, privacy-conscious, and low-overhead file sharing service is needed. It is straightforward to deploy and integrates into standard container-based workflows for small-scale production or personal use.
