About
10 minutes trainable feature flag and configuration management service with unlimited team size, awesome support and no surprises. Turn your features on/off using ConfigCat's dashboard even after your code is deployed. ConfigCat lets you target user segments based on region, email, subscription or any other custom user attribute. We support % rollouts, A/B testing and variations. ConfigCat is a hosted service for feature flag and configuration management. It enables you to decouple feature releases from code deployments. We provide open source SDKs to support easy integration with your Mobile, Desktop application, Website or any Backend system. Separate marketing releases from code deployments. This way you can deploy code anytime the development is done or even incomplete. And turn on the feature later when you are ready. Soft launch, just like the cool kids.

About
Flagsmith is a fully supported open-source feature flag, remote config, and A/B testing service. Use our hosted API, deploy to your own private cloud, or run on-premise.
Create and manage feature flags across web, mobile, and server-side applications. Wrap a section of code with a flag, and then use Flagsmith to toggle that feature on or off for different environments, users, or user segments.
Feature flags – Release features with phased rollouts and instant rollback capabilities.
Remote config – Toggle individual features on and off, and make changes without deploying new code.
A/B and multivariate testing – Use segments to run A/B and multivariate tests on new features. Introduce beta programs to get early user feedback.
Organization management – Projects, and roles for team members help keep your deployment organized.
Integrations – Connect to your favorite tools.
MCP and CLI – Set up automated feature management workflows controlled by your AI agents

Why Flagsmith is Better than ConfigCatConfigCat keeps feature flags simple, but that simplicity has its downsides. ConfigCat's SDKs work by downloading a config file containing your full flag setup—targeting rules and segment names included—so your flag logic can be exposed outside your system. Flagsmith never exposes flag configurations publicly, and sensitive flags can be restricted to server-side SDKs only. We also approach open source differently. ConfigCat's SDKs are open source; the platform itself isn't. Flagsmith's core platform is fully open source, so you can audit the code, contribute on GitHub, and avoid lock-in. We're also a founding member of OpenFeature, with all the benefits that brings to users. When you're ready to go beyond toggles, Flagsmith offers built-in A/B and multivariate testing, plus real-time flag updates with no proxy layer to host and maintain. If you want feature flag management that stays simple without sacrificing security or control, try Flagsmith. See more |

CategoriesFlagsmith is the bucketing engine for your experiments. Your analytics stack stays where it is. Create a multivariate flag, define variants with percentage weights, and Flagsmith splits traffic deterministically. Bucketing is calculated per identity, so a user gets the same variant on every evaluation until you change the weights. Use segments to restrict a test to the users you want to target: a plan tier, a region, or a beta cohort. And you can use the same mechanism to run beta programmes for early feedback. Flagsmith does not collect events or compute significance. Instead, send the variant name to the analytics platform you already use. Flagsmith has built in integrations for Amplitude, Mixpanel, Segment, Heap and Rudderstack, or push to your own pipeline over webhooks. One source of truth for metrics instead of two. Works the same on our cloud, your private cloud, or on-premise. Wrap a feature in a flag, ship the code, and decide later who sees it. The same flag can hold a different state in each environment, so nothing has to be redeployed to change behaviour in production. Targeting capabilities include boolean flags, multivariate flags, remote config values, identities with traits, segments built from rules on those traits, and percentage rollouts for canary releases. For evaluation, Flagsmith supports server-side SDKs run in local evaluation mode, resolving flags in-process with no network call per check. The Edge API serves client and mobile SDKs from the nearest geographical region. Offline mode covers environments with no outbound connectivity. 15+ open source SDKs, including TypeScript, Python, Java, C#, Go, Ruby, PHP, Swift, Kotlin and Flutter. Governance features include audit logs, role-based access control, change requests with approvals, scheduled changes, SAML SSO and SCIM provisioning. Automation is possible using the REST API, Terra |
