A secure, portable HTTP/Bittorrent server that turns any local folder into a web-accessible file-sharing service.
Skyfolder is a self-contained, portable server application that securely shares local folders over the web via HTTP and Bittorrent. It turns any device into a file server accessible on the web, automating port forwarding and providing a built-in management interface for instant file-sharing without complex configuration.
Individuals or small teams needing to quickly share files directly from their local machines without relying on third-party cloud services, such as remote workers, collaborators sharing large media files, or users hosting personal file servers.
Developers choose Skyfolder for its braindead simplicity and portability—it runs as a single executable with no installation, automatically handles router configuration via UPNP, and includes built-in TLS management with Let's Encrypt, making it secure and ready to use immediately.

Includes a Let's Encrypt client for automatic certificate issuance and renewal, ensuring secure connections without user intervention.
Consumes minimal memory (~10MB) and streams files directly from disk, making it suitable for 24/7 operation on various hardware.
Bittorrent functionality is still on the roadmap and not fully implemented, limiting current peer-to-peer sharing capabilities.
Some core features require JavaScript to work, which may break functionality in JS-restricted environments or for users avoiding it.
Lacks end-to-end encryption; while TLS secures data in transit, files are stored unencrypted on the server, as noted in the security notice.
