GemBox

GemBox makes .NET component libraries for reading, writing and converting spreadsheet, document, PDF, presentation, email and image files. The libraries are licensed perpetually per developer with royalty-free deployment, and each has a free version with size limits.

Licensing at a Glance

  • Perpetual licence
  • Named user
  • Free tier

  1. One developer licence is needed for each developer working on an application that directly or indirectly uses a GemBox library, with plans for 1 developer, up to 10, up to 50 or unlimited developers.[1]

  2. All plans include royalty-free deployment with no server or OEM licences and unlimited deployments, plus one year of technical support and free updates.[2]

  3. GemBox licences are perpetual; customers can keep using the latest version they are entitled to after the support period expires.[3]

  4. Renewals are discounted by 40%, or 60% if renewed before support expires, and renewing does not add developer licences.[4]

  5. The GemBox.Spreadsheet free version has the same features as the Professional version but is limited to 150 rows per sheet and 5 sheets per workbook.[5]
