The InAct Developers Platform aims to empower developers to integrate applications related to project tracking and management into the InAct system. Developers can build modules, addons, plugins, or third-party tools that integrate with InAct via APIs. The APIs will allow access to InAct data and functionality using PHP or JavaScript. Preparation for the platform involves improving code quality, writing documentation, and promoting the platform to developers. Challenges include the need for more human resources across various roles and sufficient time for preparation.
