Best Feature Flag Software in 2026

Updated

In short: Flagsmith is ranked #1 of 25 as of 3 October 2026, ahead of ConfigCat and Flipt. The best-ranked option with a free plan is ConfigCat. The lowest first paid tier on this page is feat at $19/mo.

Feature flags let you control the availability of software features for different users or groups, including during staged releases. Compare percentage rollouts, targeting rules, and user segments to see how each tool handles exposure. Environments and SDK languages offer a way to assess fit with your development setup; approval workflows and audit logs speak to change oversight. Free-plan availability and paid-from pricing round out the comparison. The ranking opens with Flagsmith, ConfigCat, and GrowthBook, then continues with Statsig and DevCycle. Weigh the listed controls against the way your team releases and manages features.

25 feature flag software ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
