Show HN: FFlags – Feature flags as code, served from the edge

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 you write complex rules, which felt more natural as a developer myself than using a complex UI for logic.

2. Open Standard: The platform is built on the OpenFeature standard (specifically the Remote Evaluation Protocol). The goal is to avoid vendor lock-in and the usual enterprise slop. You're not tied to my platform if you want to move.

3. Performance: It uses an edge network to serve the flags, which keeps the wall-time latency low (sub-25ms) for globally distributed applications.

I was trying to avoid the heavy cost and complexity of existing enterprise tools while still getting better performance than a simple self-hosted solution.

There's a generous free tier ($39 per million requests after that, with no flag/user limits). I'm looking for feedback on the developer experience, the "flags-as-code" approach, and any technical questions you might have.

Thanks for taking a look.

This product is probably not intended for me but at this stage I'm not even sure I know what a feature flag is any more.

I thought feature flags were just toggles so you could turn features on and off. I wouldn't know how to implement those as anything other than code. Or why you would need an external service.

What problem is this solving?

One of the key aspects of feature flag systems is enabling A/B analysis, measuring the impact of features on metrics like click-through rate, session duration, and revenue. This doesn’t seem to be mentioned in the highlights. Is the product targeting these kinds of insights?

Why does this need to be a dependency? In my view feature flags are core enough not to be outsourced to a third party. Although, there are companies using libraries for "isEven" so there might be a market for it.

Love the simple landing page! How big is the free tier? The pricing slider seems to show that you pay $39 for anything more than 0 requests.

Cool product and great landing page. This is quite off topic: how did you make the code animation in the Feature Flag as Code section? I reminded me of prezi.com (with their slide animations). Would love to know!

Great product! Actually a big point that I've seen in enterprises.
