The community packages use Apache 2.0. You can use them in commercial products without paying EigenPal.
Pro covers production use of @pptx-editor.dev/pro, @pptx-editor.dev/editor-api, and @pptx-editor.dev/pptx-to-pdf in one product. Buy another subscription for a second product or a white-label offering.
The bundle covers PPTX Editor Pro and DOCX Editor Pro in the same product for $750 a month, with one API key.
After checkout, your API key is on the next page and in your confirmation email. You can read it again and manage billing in the customer portal.
Cancel before renewal to stop the next charge. Your Pro license ends after the paid month. You must then stop using and remove the Pro packages from your product. Read the Licensing Terms.
