OnionShare

What OnionShare is

OnionShare is a free, open-source tool for sharing files, hosting websites, and chatting over the Tor network. It starts web servers locally on the user’s computer and makes them accessible as Tor onion services. In receive mode, other people can upload files anonymously directly to that computer; a configured webhook can receive an HTTP POST when files or messages arrive. OnionShare can also host onion websites and create private chat rooms that do not log chat history. Its security documentation says file sharing does not send files to a third-party server and Tor onion service connections are end-to-end encrypted. Services are protected by a private key by default. File sharing stops automatically after a recipient finishes downloading unless that setting is disabled. OnionShare warns that uploaded files may be malicious and does not add safeguards for the user’s system against them. Desktop downloads are listed for Windows, macOS, and Linux, with mobile apps for Android and iOS. The project says its apps collect no analytics or behavioral tracking; website logs are retained for two weeks without IP addresses. OnionShare is a Lockdown Systems collective project released under GPLv3.
