Get early accessFeature flags for Ruby apps and their client-side code. Roll out new features gradually. Provide early access to key customers. Test drive features internally.
“...we deeply rely on Flipper to build PlanetScale. Every database version rollout across our infrastructure starts with Flipper flags.”

Merge it with the flag off, roll it out a few customers at a time, and turn it off if anything breaks.
## Feature flags
- Put every user-facing change behind a Flipper feature flag.
- Test both paths: Flipper.enable and Flipper.disable.
- Never enable flags in production. A person rolls it out.
- Remove the flag 14 days after it's fully enabled.

“It would be impossible to ship as many times a day as we do without feature flags. And Flipper is the tool we trust to handle that for us.”

















“It’s a breeze to incorporate into a project: add the gem, run a command to generate a migration, mount a web interface in the routes along with the admin panel, add a link from there, and write some wiring code to replace your solution with Flipper under the facade and you’re done. Easy-peasy, lemon squeezy!”

“Before Flipper, I wasted time coordinating release plans, long-running feature branches, and endless merge conflicts. Now I merge everything to main behind Flipper flags and can focus on shipping new features.”
