Feature Flags for Real Platform Reliability

Separate deployments from releases, A/B test new features before scaling, and instantly roll back problem code without having to redeploy. Feature flags help you build a golden path that scales—without slowing developers down.

Get engineering teams moving faster, without sacrificing safety

Deploy new features behind flags and release when ready, improving development velocity

Release progressively, strengthening features and validating with real-world data before GA

Disable buggy code at the individual feature level—no need for sweeping rollbacks

“Without feature toggling, we’d run a deployment, do a check, and find something. Then we’d have to decide to live with it or roll it back. Rolling back meant a wasted night. With Flagsmith, we can turn things on or off individually on a feature level, so it’s just really made things smoother for us.”

- Senior Manager, Software Engineering, Fortune 500 healthcare company

“Flagsmith is both very simple and very powerful. It lets us manage our features and capabilities in a seamless and scalable way that lets us focus on what we do best: building security software.” - Dariel Marlow, VP of Cloud Engineering, Delinea
