Markdown feature flags your coding agent installs for you
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.

- Open-source and easy to integrate into existing workflows
- No account or complex setup required, simplifying adoption
- Centralizes feature flags, reasons, and decisions in version control
- Supports A/B testing within the same files for streamlined experimentation
- Lightweight and developer-focused
Cons
- Limited to users comfortable with Markdown and GitHub workflows
- May lack advanced feature flag management features found in dedicated SaaS solutions
- No built-in analytics or traffic management tools
Best for
- • Managing feature flags within a GitHub-centric development team
- • Documenting decision rationales behind feature releases
- • Conducting A/B tests directly within codebase files
- • Streamlining feature rollouts without additional SaaS tools
