Remote help, kept close to home.

Help your parents, your neighbours or the small office down the road with their Windows PC, from wherever you are. HelpBuoy connects through a relay you run yourself, asks them before every session, and hands control back the moment they press Esc.

How it works

You set it up once. After that, helping takes a phone call and two clicks.

  1. Start HelpBuoy Desk

    It runs a small relay on your own computer. Open port 5959 on your router once, so the people you help can reach it.

    You, once

  2. They install HelpBuoy

    They type your address and their app shows a key. They send it to you over WhatsApp, Signal or email.

    Them, once

  3. You add their key

    Paste it into the desk app. From then on their PC shows up in your list whenever HelpBuoy is open.

    You, once

  4. Connect, and they say yes

    Press Connect, they press Allow. You see their screen and fix things while you talk on the phone.

    Every time you help

The desk app

One calm window with everyone you look after. It runs on Windows and Linux.

Everyone whose HelpBuoy is open right now. One click on Connect asks them if you may help.

What it does, and what it never does

HelpBuoy is deliberately small. It does one thing: lets you see a screen and use its mouse and keyboard, with permission.

It does

  • Shows you their screen, sharp and quick, close to the speed of Remote Desktop
  • Lets you use their mouse and keyboard
  • Asks them first, every single time, and shows who is asking
  • Stops the moment they press Esc or close the program

It never does

  • Copies files to or from their PC
  • Reads their clipboard
  • Runs commands or opens a shell in the background
  • Starts by itself or keeps running after they close it
  • Sends anything through our servers. There aren’t any.

Your relay, your rules

Most remote support tools route every session through the vendor’s servers. HelpBuoy doesn’t have servers. The relay is a single small program that runs on your own computer, or on a machine in your office.

Sessions are encrypted end to end between your desk app and their PC. The relay only connects the two; it can’t see the screen and can’t read the keystrokes. Nobody else can either, us included.

Questions people ask

Does the person I help need an account or a password?
No. They install HelpBuoy, type your address once and send you their key. There are no accounts anywhere.
Can I connect without them knowing?
No. Every session starts with a question on their screen, showing your name. Nothing happens until they press Allow, and pressing Esc ends the session immediately.
Which computers does it work on?
The person you help needs Windows 10 (version 2004 or later) or Windows 11. You can help from Windows or Linux; a macOS version of the desk app is on its way.
Do I need a server?
No. The relay is built into the desk app and runs on your own computer while it is open. If you want it to be reachable all the time, there is a Debian package that runs it as a service on an always-on machine.
What does it cost?
Nothing. HelpBuoy is free for everyone, including businesses. Paid email support is optional.
Can it send files or copy and paste?
No, on purpose. HelpBuoy only shows the screen and passes on mouse and keyboard. That keeps it simple, and it keeps the people you help safe.
