OnionShare for Mac

Brief overview

OnionShare is a free, open-source tool that makes anonymous file transfers, website hosting, and encrypted messaging easy over the Tor network. It is built for simplicity: each core task lives in its own window, so users can get things done without deep technical know-how. Because it runs multiple operations at once (similar to opening several tabs in a browser), you can work on more than one task simultaneously.

Core functions

• Host private websites accessible via Tor (.onion addresses)
• Receive files from others by creating a temporary upload endpoint
• Open short-lived chat rooms for encrypted conversations
• Share files by producing a link recipients can use to download

How the interface works

Each capability is presented in its own dedicated window, which keeps workflows separated and straightforward. Controls and options are pared down to essential choices so that both beginners and experienced users can operate the application with minimal fuss. The ability to run several sessions in parallel improves productivity when you need to share, host, or chat at the same time.

Privacy and security features

• Unique, single-use or time-limited links are generated for file transfers and chat sessions to limit access.
• Temporary chat rooms automatically disappear after the session ends, reducing data persistence.
• No account signup is required to start a chat, which helps preserve anonymity and lowers the barrier to secure communication.
• All traffic is routed through the Tor network, keeping IP addresses and locations concealed.

Suggested alternative

If you prefer a more traditional FTP-style client, consider FileZilla (free). It’s not focused on Tor anonymity but is a solid option for encrypted file transfers over standard internet connections and FTP/SFTP workflows.

Final note

For anyone seeking a straightforward, privacy-first way to share files, host small Tor-accessible sites, or hold private chats without creating accounts, OnionShare is a strong, easy-to-use choice.
