Plans
Three plans to suit how you work. Free is great for getting started, Pro removes the connection limit, and Enterprise adds the 1:1 scale formboard layout.

How to Upgrade
In the app go to Main Menu → Account and select

Pick the Pro or Enterprise plan, choose whether you want to pay Monthly or Annually, and select Upgrade now.
This will take you to a Stripe payment window where your payment will be processed.
What is a Connection
A connection is a single conductor running between two components, such as a connector cavity, terminal, splice, resistor, or diode.
Some examples:
- A single wire = 1 connection
- A 4-core cable with a shield = 5 connections
- Twisted wires = 1 connection per wire
How to see the Number of Connections
Go to the Connections view and scroll to the bottom to see the number of connections in the harness.
How to cancel a paid plan
Go to the Main Menu → Account and select Manage subscription. Stripe will open up automatically. Select Cancel subscription.
What happens if I cancel?
If you cancel, your plan stays active until the end of your current billing period. Once the period ends, your account reverts to the Free plan. Nothing is deleted — you keep all your harnesses and their data — but the paid features stop accepting new work:
- Any harnesses exceeding 100 connections will no longer accept new connections until the total is reduced below the limit. You can still use and edit those harnesses.
- Revisions you’ve already created stay intact. You can still view and restore them, but you can’t create new revisions until you’re back on a paid plan.
- Email sharing winds down. People you’ve already invited by email keep their access, and you can still view and revoke those shares, but you can’t send new email invites. Public link sharing remains available on Free.
- If you were on Enterprise, formboard harnesses become read-only — you can still view and turn off formboard mode, but not edit it or turn it back on.
- If you were on Enterprise, team collaboration pauses. You keep ownership and full control of every harness — including any you moved into a team — but you can no longer invite members or assign seats. Restore your Enterprise plan to collaborate with your team again.
