FAQ#

Can I upgrade from Individual to Team? Yes. Purchase the Team plan and activate with your new key. See the FAQ for the full upgrade procedure.

What happens when my trial expires? import lactuca raises LicenseExpiredError. Purchase any paid plan to continue.

Is VAT included in the prices shown? No. Prices shown are ex-VAT. Lemon Squeezy adds the applicable VAT for your jurisdiction at checkout.

Can I use Lactuca in a CI/CD pipeline? Yes — set the LACTUCA_LICENSE_KEY environment variable. See the Activation Guide.

OEM and SaaS Licensing#

If you want to embed Lactuca as a calculation engine in a product or service distributed or made available to your own clients or external users, you need an OEM license — a separate written agreement with Licensor.

Standard license tiers (Individual, Team, Enterprise) do not cover OEM use.

Typical OEM scenarios:

  • A SaaS platform running Lactuca server-side for your customers.

  • An application or API sold to third parties that calls Lactuca internally.

  • Any product where your clients benefit from Lactuca without obtaining their own Lactuca license directly from Licensor.

To enquire about OEM licensing, contact support@lactuca.io with a description of your product and estimated scale.
