The Glyph Developer Kit (GDK) is an official software development kit (SDK) released by Nothing to enable third-party developers to integrate their apps and services with the [[software:glyph_interface|Glyph Interface]] and [[software:glyph_interface#glyph_matrix|Glyph Matrix]]. The kit empowers developers to craft custom LED animations and notifications across supported Nothing phones.

====== Release & Availability ======
The GDK was officially released in February 2024 and was made accessible via GitHub. It initially supported the [[hardware:phone_1|Phone (1)]] and [[hardware:phone_2|Phone (2)]] models, offering control over the devices’ 12 and 33 LED light zones respectively.((https://nothing.community/d/5595)) It has since been updated to support [[hardware:phone_2a_series|Phone (2a) series]].

The second version of the GDK was released 1 July 2025 and was designed for [[hardware:phone_3|Phone (3)]]’s [[software:glyph_interface#glyph_matrix|Glyph Matrix]]. This allowed developers to create Glyph Toys and integrate their apps with the Matrix for notifications, games, animations and more. In September 2025, Nothing released their first party platform, [[software:essential_apps_and_playground|Playground]], which featured a way for users to discover and download community developed Glyph Toys.((https://nothing.community/d/35633))

For all models prior to [[hardware:phone_3|Phone (3)]], developers must register for an API key to unlock the usage of the GDK in production apps, without the need for developer mode. As of [[hardware:phone_3|Phone (3)]], this key is no longer required.((https://nothing.community/d/5595))((https://nothing.community/d/35633))

====== Use Cases ======
The GDK has primarily gained excitement among developers within the [[community|Nothing community]], eager to experiment and create Glyph-enabled apps and projects. Some notable examples include:
  * **Glyph Museum**: A way to discover, create and display art and animations on the [[software:glyph_interface#glyph_matrix|Glyph Matrix]].((https://nothing.community/en/d/46572))
  * **Simone**: A memory game inspired by the classic “Simon”, using the Glyph lights as the interactive interface.((https://nothing.community/d/8969))
  * **Better Nothing Glyph Composer (BNGC)**: A website to create audio-reactive LED Glyph compositions using your own custom audio.((https://better-nothing-glyph-composer.pages.dev/))
  * **Custom Nothing Glyph Tools**: A desktop tool to create Glyph tones with Audacity.((https://github.com/SebiAi/custom-nothing-glyph-tools))
