FFlags – Feature flags as code, served from the edge

In plain words

FFlags is a feature flagging system that lets developers define flag logic in TypeScript code rather than through a UI. Built on the OpenFeature standard, it avoids vendor lock-in by using an open protocol that allows users to migrate between platforms. The system serves flags from an edge network with sub-25ms latency for distributed applications. It targets developers who want enterprise-grade performance and reliability without months of implementation time or dependency on a single vendor.

From the sources

FFlags is an OpenFeature-compliant feature flag service that enables you to write custom flag logic using TypeScript.

Get the sub ~25ms wall-time performance and enterprise-scale reliability without months of development time. You can define the flag logic in JavaScript so the responses are consistent and predictable. The application is based on OpenFeature to ensure there's no vendor lock-in and you are free from the enterprise slop. using @ctushr 's fflags .com on prod to switch currency based on user's locations. 1. Intuitive like hell. 2. Blazing fast. 3. Huuuuge free tier. Well done Tushar! Will be using fflags for all my products going forward. FFlags use OpenFeature Remote Evaluation Protocol specs to serve feature flags. Flags are defined in code. This allows you to write complex logic and use the…from fflags.com

In the maker’s words, at launch

Hi HN, I'm the creator of FFlags. I built this because I wanted a feature flagging system that gave me the performance and reliability of an enterprise-scale solution without the months of dev time or the vendor lock-in. The core ideas are: 1. Feature Flags as Code: You define your flag logic in TypeScript. This lets…

  Hey all, I'm the founder of Flipt, an open-source (https://github.com/flipt-io/flipt) feature flag tool that I (and others) have been working on for the past few years. About a year or two ago we added support for serving flag state from various non-relational declarative stores like Git, OCI, Object Store, etc. Many of our users came to love the git-backed storage, as it allows them to keep their feature flags close to their code in there organization's repos. But they had one (rather large) ask, and that was the ability to use the UI to manage flag state changes and…

  Talanoa▲341

  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 – 25MB CPU-Only, Open-Source TTS Model▲1,003

  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…

  The current sky at your approximate location, as a CSS gradient▲788

  For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript.
