About dif.sh

Dif.sh is an open-source tool designed for developers who want to streamline the management of feature flags directly within their GitHub repositories. By using Markdown files to document feature flags, the reasons behind decisions, and the current status, it centralizes feature management in a simple, version-controlled format. The tool is intended for teams seeking a lightweight, no-account solution that integrates seamlessly with their existing workflows, allowing feature flags and A/B tests to be reviewed and adjusted within pull requests. Its unique approach of embedding feature flags as Markdown files makes it easy for developers to review, update, and track decisions, reducing the complexity often associated with feature flag management tools. With just one command, developers can install and update flags, enabling their coding agents to finish the setup, making deployment more efficient and transparent.
