Server-Driven UI iOS macOS tvOS Flutter Cross-Platform Mobile Development Developer Tools

Overview

FastGooey is a server-driven UI toolkit that lets developers define and update app interfaces from the backend without shipping new app builds. It renders natively on Apple platforms including iOS, macOS, and tvOS, and also supports Flutter for cross-platform reach. By centralizing UI logic on the server, FastGooey enables faster iteration, A/B testing, and consistent experiences across devices. Teams can push layout, content, and behavior changes in real time, reducing release cycles and app store review delays. It is aimed at mobile and multi-platform teams that want to decouple UI updates from binary releases while keeping native performance and look-and-feel.

Compared a few options

Evaluated this against two competitors. Where it wins: native iOS, macOS, and tvOS support and faster iteration and experimentation. Where it lags: learning curve for server-driven UI patterns. On balance the feature set — especially native iOS, macOS, and tvOS support — justifies the 5 stars for our use case.

Use it every day

Honestly didn't expect to like it this much. Decoupled UI from app binaries is exactly what I needed, and native rendering on iOS, macOS, and tvOS. but I reach for it almost every day now and it just clicks.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on server-driven UI rendering, and faster iteration and experimentation caught me off guard. still, I'd recommend giving it a real trial.

Q&A

Who is Self-Hosted for?

It is aimed at agencies, enterprises, and teams that need data sovereignty, private infrastructure, or a non-SaaS procurement model while still wanting native app rendering.

Asked by Zelda Brandt · Jan 2, 2026

How is it different from hosted FastGooey?

The core difference is operational ownership. Self-Hosted runs in your Umbraco environment and avoids recurring platform fees, while hosted FastGooey removes the infrastructure work.

Asked by Celeste Marchetti · Dec 11, 2025

How do I install it?

Install it as a standard NuGet package in your existing Umbraco CMS instance, configure the content model there, and point your native app at the self-hosted endpoint.

Asked by George Papadakis · Oct 6, 2025

What UI can it render today?

Self-Hosted currently supports core macOS views like Table, SourceList, and Outline, plus iOS List View, with native UIKit and AppKit output.
