Hypertune

Product Introduction

1. Hypertune is a unified platform for managing feature flags, A/B testing, analytics, and app configuration, designed specifically for modern TypeScript, React, and Next.js applications. It provides end-to-end type safety across all environments, including frontend, backend, serverless, and edge runtimes, ensuring consistent flag evaluation without runtime errors.
2. The core value lies in its ability to streamline development workflows by combining type-safe feature management with real-time analytics, enabling teams to deploy, test, and optimize features confidently while maintaining code integrity across distributed systems.

Main Features

1. Type-Safe Feature Flags: Hypertune generates a typed client SDK that validates flag logic at compile time, eliminating runtime errors caused by incorrect inputs or deprecated flags. Developers define flags with custom inputs (e.g., user roles, environment variables) and enforce strict typing across all code paths, including server-side rendering (SSR) and edge functions.
2. Hyperlang Targeting Engine: A statically-typed visual configuration language allows granular targeting of users, organizations, or environments using reusable variables and logic structures. Rules support complex conditions (e.g., A/B test allocation, geo-based rollouts) while maintaining type safety, with an in-app debugger to validate evaluations in real time.
3. Local Evaluation & Build-Time Snapshots: Flags are evaluated locally with zero network latency, using preloaded snapshots during builds or serverless deployments. This prevents layout shifts in SSR by dehydrating state on the server and rehydrating it client-side, ensuring consistent initial renders.

Problems Solved

1. Runtime Errors in Feature Management: Hypertune eliminates typos and incorrect flag usage by enforcing type safety at every stage, from configuration to client-side evaluation. This prevents production outages caused by mismatched flag states across frontend and backend systems.
2. Cross-Functional Team Collaboration: Product managers, marketers, and developers can collaboratively manage flags and A/B tests through a unified interface with granular permissions, avoiding siloed workflows and misconfigured targeting rules.
3. Slow Iteration Cycles: Teams rapidly test hypotheses using integrated A/B testing and AI-driven analytics, with instant rollback capabilities and real-time performance metrics. Use cases include phased feature rollouts, dynamic in-app copy personalization, and optimizing serverless function configurations.

Unique Advantages

1. Full-Stack Type Safety: Unlike competitors that offer partial typing or separate SDKs for different environments, Hypertune provides a single TypeScript SDK with end-to-end validation, ensuring flags remain consistent across browsers, servers, and edge networks.
2. Vercel-Native Architecture: Optimized for Next.js and Vercel Edge Config, Hypertune initializes flags during build time and seamlessly integrates with Vercel’s toolbar for frontend overrides. This reduces setup time for Vercel-hosted apps to under 5 minutes.
3. Git-Based Version Control: Flag configurations are managed via Git branches with diff tracking and pull requests, enabling audit trails and seamless synchronization across staging/production environments without manual state management.

Frequently Asked Questions (FAQ)

1. How does Hypertune ensure type safety across distributed systems? Hypertune generates client SDKs from your flag definitions, embedding static types directly into the codebase. This guarantees that all flag references in frontend, API routes, and edge functions match the configured schema, even after updates.
2. Can Hypertune handle server-side rendering without layout flicker? Yes, the SDK dehydrates flag states during SSR and rehydrates them client-side in the first render, ensuring no mismatch between server and client evaluations. Build-time snapshots further eliminate network calls during initialization.
3. How does Hypertune differ from open-source feature flag libraries? Unlike basic flag tools, Hypertune combines type safety, Hyperlang’s visual rule builder, and AI-powered analytics into a unified platform. It supports advanced use cases like monorepo sharing, edge runtime optimizations, and Git-based versioning out of the box.
4. Is Hypertune suitable for edge function environments like Vercel Edge? Yes, the SDK is optimized for low-memory edge runtimes and supports initialization with subsetted flag configurations to reduce bundle size. Evaluations occur locally without external API calls, ensuring sub-millisecond latency.
5. How are analytics integrated with feature flags? Hypertune automatically tracks flag evaluations and ties them to custom events (e.g., button clicks, conversions) with typed payloads. Teams analyze impact via built-in dashboards or export data to tools like Segment and Datadog.
