GRBL Server
Sign up

Login & accounts

GRBL Server is free, and you don't need an account to use it: install it, open it and start engraving. Machines, jobs, the Library, workflows and every other feature work without signing in, and your workflows, files and machines stay on your local server throughout.

The one thing that involves the website is the AI assistant included with GRBL Server — the workflow assistant answering without an AI key of your own. It's free for a month, then $3.99/month. You can also use the assistant with your own key at no charge from us; see Choosing who answers.

Starting the free month (no account)

  1. In GRBL Server, click Account at the bottom of the sidebar.
  2. Click Start your free month.
  3. That's it — the included assistant works on this computer for one month. No account, no card.

What an account is for

An account is only needed to subscribe to the included assistant. The account:

  • Carries your subscription ($3.99/month after the free month), managed from your dashboard.
  • Turns the included assistant on for every workshop computer signed in with it — and a new account comes with its own free month, if you'd rather start with one.
  • Stores your contact email so you can be reached about important updates.

Creating an account

  1. Go to https://grblserver.com/register.
  2. Enter your name, email and a password.
  3. Submit. You're signed in immediately on the website.
  4. Click the link in the email we send you. The desktop app only accepts a confirmed email, so do this before signing in there.

Signing in from the desktop app

  1. Click Account at the bottom of the sidebar. (You can also do this from another computer's browser, using the address on the Network access page.)
  2. Click Sign in — or Sign in to your account while the computer is on its free month.
  3. Use the same email and password you set up on this website.
  4. That's it. The host stays signed in across restarts — you won't be asked again on this computer unless you sign out.

Moving from the free month to your account

You don't have to wait for the free month to end. As soon as you've created an account and confirmed your email, open the Account page, click Sign in to your account and enter your email and password. The sidebar then shows your name instead of the free month.

Nothing changes unless the sign-in succeeds: a mistyped password or an unconfirmed email leaves the free month running and tells you why. If the account has no subscription, GRBL Server says so — subscribe on the website, then click Check now on the Account page.

The Account page

The button at the bottom of the sidebar shows who GRBL Server is signed in as — or, on the free month, how many days are left — and opens the Account page. It shows whether the included assistant is on, when the free month or subscription ends, which computer this is and when the account was last checked, and it's where you:

  • Start your free month or Sign in.
  • Subscribe or Manage subscription on the website.
  • Check now — GRBL Server checks your account in the background, but if you've just subscribed or renewed, this picks it up straight away.
  • Switch account or Sign out.

Using GRBL Server without internet

GRBL Server doesn't need the internet: engraving, cutting, workflows and everything else on the workshop computer work offline, for as long as you like. Only the included assistant needs a connection, since it answers through this website.

Forgot your password?

  1. Go to https://grblserver.com/forgot-password.
  2. Enter the email you registered with.
  3. Check your inbox for the reset link (it arrives within a few minutes — check your spam or junk folder if it doesn't).
  4. Set a new password and sign in again from the desktop app.

Managing your devices

From your dashboard on the website you can:

  • See every host that has signed in with your account at Devices.
  • Remove a host you no longer use — it's signed out the next time it checks your account, and the included assistant stops there.

Signing out or switching account

Open the Account page from the bottom of the sidebar:

  • Switch account signs this computer in with another account in one step — useful if you're handing the workshop computer to someone else. You stay signed in as you are until the new sign-in succeeds.
  • Sign out removes your account from this computer. GRBL Server keeps working exactly as before, for everyone using it; only the included assistant stops until someone signs in again.
