The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Defold.

  • The Defold License requires you to include the Defold license and copyright notice in any work you create with the engine
  • The licence forbids commercialising original or modified versions of the Defold editor or engine itself
  • Significant changes made to the Defold source must be documented under the licence terms

Softwr does not host reviews and shows no star rating for Defold, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it. Tell us if any of it is wrong.
