Dif is an open source tool for feature flags, A/B tests, holdouts, and staged rollouts directly in your repository. Each experiment lives in a Markdown file, versioned with Git and reviewed through pull requests. With a simple CLI and no signup, Dif also provides validation, conflict detection, coding agent context, and analytics integrations through your own stack or Dif Cloud.
