Plans and licenses

How Free, the Pro trial, paid licenses and computers work, and what happens when a license ends.

Plans

  • Free is for personal use, education and in-house evaluation. It needs an e-mail account and runs on one computer.
  • Pro is for commercial work and runs on two computers. New accounts get a 30-day Pro trial, started online.
  • Team is Pro for 2–20 seats on one license key, with two computers per seat.
  • Enterprise adds yearly license files for air-gapped computers, usage data off, SLA and training.

See Pricing for the full comparison.

After buying

If you bought with the same e-mail you use in the app, select Renew license now on the License page; Pro is applied without a key. You also receive the license key by e-mail: enter it under Change license → License key → Activate key.

Computers

Each license allows a fixed number of computers. To move to a new computer, select Release this computer on the old one (or release it on your account page if the old computer is gone), then activate the new one. Releasing is limited to a few times a month.

Working offline

The app checks the license at start and about once a day. Without a connection it keeps working for 30 days; connecting once renews this. If our server can’t be reached, the app keeps working. Computers that can never connect use offline activation.

When a license ends

When a paid license or the trial ends, the app returns to Free. Nothing is deleted: projects over the Free limits can still be opened and viewed; saving or running them asks to upgrade.
