About shapt

Shapt is an Elixir library for managing feature toggles, flags, and flippers in your code. It provides a simple and configurable system with pluggable adapters, including built-in environment variable and dotenv adapters. The library includes mix tasks for identifying expired toggles and generating adapter template files. It also offers plug endpoints for inspecting current toggle states and reloading their values. Currently in active development with an evolving API, Shapt serves Elixir developers looking for a flexible feature flagging solution with extensible architecture and reasonable defaults.
