Open source feature flags. Every flag is a markdown file that lives with the code it controls: what it does, why it exists, and what you decided, reviewed in a PR like any other change. Your coding agent installs Dif in one command, no account, and reads the context file so it knows what's live and what was already tried. A/B tests wait in the same files until you have traffic. Send events to your own analytics, or let Dif Cloud read the results and write the decision into the file.
