Product maturity lifecycle

This page describes the maturity stages that we use to communicate the stage of development of GDK features.

Throughout the GDK documentation, you’ll see references to these maturity stages.

Understanding these stages can help you answer questions such as:

  • Can I rely on this feature for an external playtest of my game? Has another studio already used this feature in an external playtest?
  • Can I rely on this feature for day-to-day development? Are other studios using it, and will Improbable support me using it?
  • Is this feature still being developed, or is it already proven and unlikely to change significantly?
