Self-hosted remote support for Windows, Linux and Mac, a small alternative to TeamViewer QuickSupport.

HelpBuoy lets a support techie take over the screen of someone who asks for help. You run your own server, a single Go binary that speaks SSH on one port. It authenticates keys and connects techies to computers, and nothing else: no shell, no file transfer, no forwarding. A session only carries the screen and the mouse and keyboard input, and the person receiving help approves every connection.
