Login & accounts
Signing in is required to use GRBL Server. Each host computer signs in once with your account — after that, anyone on the local network can use it from a browser without signing in again. Your workflows, files, and machines stay on your local server; the account just unlocks the app.
What an account is for
- Unlocks the desktop app on the workshop computer.
- Stores your contact email so you can be reached about important updates.
- Locks in the early-supporter price for when paid plans launch.
- Later on, will be the entry point for optional cloud features (backup, sync, sharing) — off by default.
Creating an account
- Go to https://grblserver.com/register.
- Enter your name, email and a password.
- Submit. You're signed in immediately on the website.
- If email verification is enabled, click the link in the email we send you.
Signing in from the desktop app
This is the one mandatory step before you can use GRBL Server on a host.
- Open GRBL Server in a browser using the address shown in the launcher window (e.g.
http://192.168.1.42). - The first page you see is Sign in to GRBL Server.
- Use the same email and password you set up on this website.
- That's it. The host stays signed in across restarts — you won't be asked again on this computer unless you sign out, or your account is no longer valid.
Using GRBL Server when the internet drops
Workshop internet isn't always reliable, and that's fine. Once a host is signed in, GRBL Server keeps working for several days even if the connection drops — you can engrave and cut without any interruption.
When the host has been offline for longer than that, it'll politely ask to reconnect before letting you continue. Plug back into the network, click Re-check licence on the screen it shows you, and you're back in business.
If the app stops letting you in
If something's wrong with your account or licence, every page is replaced with a clear lockout screen that tells you what's going on. The two things you'll see most often:
- "Your licence has expired" / "Your licence is cancelled" — renew or re-activate your account on the website, then click Re-check licence on the lockout screen. The app unlocks within a moment.
- "This host has been offline too long" — see the section above. Reconnect and re-check.
From the lockout screen you can also Sign out and sign in with a different account, which is useful if you're handing the workshop computer to someone else.
Forgot your password?
- Go to https://grblserver.com/forgot-password.
- Enter the email you registered with.
- Check your inbox for the reset link (check spam too — indie domains sometimes land there on first contact).
- 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'll be asked to sign in again next time someone tries.
Signing out
From any browser session — or from the lockout screen — click Sign out. The host returns to the sign-in screen so another account can be used on the same computer.
