What does Hypertune do?

Hypertune is a platform for managing feature flags, A/B tests, and application configuration. It lets development teams control which users see new features, run experiments, and change app behavior without deploying new code. Everything is managed through a central dashboard and integrated directly into your codebase with a type-safe SDK. This means you can turn features on or off for specific users, roll out changes gradually, or test different variations with real users.

The tool stands out with its deep integration for modern TypeScript-based stacks. It generates a type-safe client from your flag definitions, so your IDE can catch errors before runtime. It uses a custom, functional language called Hyperlang for writing targeting rules, and all configuration is version-controlled with Git. This provides a full commit history, branching, and pull requests for your feature flags, similar to how you manage code. It also supports local evaluation, so flag checks happen without network calls, keeping your app fast.

Hypertune is built for engineering teams using TypeScript, React, and Next.js. It's particularly useful for developers and product managers who need to deploy features safely, marketers who want to run targeted campaigns, and anyone managing complex application configuration. Use cases include gradually rolling out a new UI, running an A/B test on a pricing page, or enabling a feature only for users in a specific company or plan.
