Hypertune

Hey HN! I'm Miraan, the founder at Hypertune, and I'm excited to be posting this on HN. Hypertune lets you make your code configurable to let teammates like PMs and marketers quickly change feature flags, in-app copy, pricing plans, etc. It's like a CMS but instead of only letting you set static content, you can insert arbitrary logic from the UI, including A/B tests and ML "loops". I previously built a landing page optimization tool that let marketers define variants of their headline, CTA, cover image, etc, then used a genetic algorithm to find the best combination of them. They used…

Hypertune launched on August 3, 2025 with 260 votes, #131 of 8,530 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 1 year on.

In plain words

Hypertune is a feature flags and configuration platform designed for React and Next.js developers. It provides type-safe feature flags, A/B testing capabilities, analytics, and app configuration management. The platform is optimized for TypeScript, React, and Next.js projects, making it particularly suited for developers building modern JavaScript applications who need flexible control over feature rollouts and testing.

Hypertune is shutting down . We're no longer accepting new sign ups. The service will shut down on 10th August 2026. Sign in if you already have an account. No juggling different SDKs for the frontend, backend, and mobile client. Install and set up one TypeScript SDK that works everywhere. Build targeting rules in Hyperlang — our functional, statically-typed configuration language with real-time analytics built in. Local flag evaluation with zero network latency means you can use the SDK anywhere without degrading the end-user experience. All your feature flags, experiments, analytics events, and app configuration are versioned together in a single Git-basedfrom hypertune.com

    I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!

    We just launched Croct Templates, a way to drop CMS-powered components into your app with a single command. It's like Shadcn, but for CMS, AB testing and personalization: * Built-in support for A/B testing, content editing, and dynamic logic * Works with existing projects (Next.js, React, etc.) * Supports community libraries via `npm://`, `shadcn-ui://`, etc. Example: ```bash npx croct@latest use shadcn-ui://block/pricing-page ``` Happy to answer any questions!

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  • Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…
