Developers in need of a simple, flexible solution to manage feature flags in their web applications
About Flags SDK
Flags SDK is an open source library designed for integrating feature flags into Next.js and SvelteKit applications. It allows developers to manage and implement feature flags, providing flexibility with integrations for any flag provider. The SDK supports AB testing, controlled rollouts, and experimentation, helping developers ship features faster and more efficiently. It features a simple, declarative API to define and use flags, making integration effortless. With Flags SDK, developers can release new features strategically, test them in production without breaking apps, and experiment with confidence. The toolkit ensures the website remains fast while following best practices for feature flag usage.

Hypertune
Hypertune is the most flexible platform for feature flags, A/B testing, analytics and app configuration. Built with full end-to-end type-safety, Git-style version control and local, synchronous, in-memory flag evaluation.
- Define type-safe, custom inputs like the current User, Organization, etc, and use them in feature flag rules to target exactly the users you want.
- Create variables like user segments that you can reuse across different feature flags, and instantly debug flags for each user.
- A/B tests, percentage-based rollouts, multivariate tests and machine learning loops let you seamlessly rollout, test and optimize new features.
- Log analytics events with type-safe, custom payloads, and build flexible funnels and charts in the dashboard to measure the impact of every feature release.
- Initialize the SDK with only the feature flags you need and partially evaluate flag logic on the edge for performance and security.

Flagsmith
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.
Flagsmith makes it easy to create and manage features flags across web, mobile, and server side applications. Just 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 confidence through phased rollouts.
Remote config - Easily 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. With segments, you can also introduce beta programs to get early user feedback.
Organization Management - Organizations, projects, and roles for team members help keep your deployment organized.
