Reduce App

A simple Mac utility from the creators of Flawless to reduce the size of heavy Sketch files. Reduce app lets you drag in any Sketch file and it will attempt to optimise image sizes, remove broken images, delete hidden layers, and delete unused symbols with the aim of dramatically reducing the size of the file.

Haiku

A new design tool for animated and interactive user interfaces. Haiku aims to connect design and implementation by generating native code that automatically updates in your apps as you design. It starts with designs imported from Sketch which you can then add animations to using the Haiku Mac app. You can then export your designs in native code using the Lottie framework on iOS and Android and React on the web. Once implemented you can use the Haiku command line tool to keep your app in sync while making changes to your designs in realtime.

Flawless

A real-time comparison tool that lets you compare your expected and implemented designs. Flawless is built into iOS simulator so is easy to make part of your development workflow. You start by dragging in your designs in any of a number of different formats (including Sketch), which will then appear on your iOS simulator. You can then toggle between overlay or split comparison modes for spotting any visual differences between the expected design and your implementation.

Lona

A collection of tools from the developers and designers at Airbnb for building design systems and using them to generate cross-platform UI code, Sketch files, images, and other artifacts. Lona starts with a collection of JSON files that are used to define a design system including components, colours, text styles, gradients, shadows, and data type. The first tool is Lona Studio which provides a graphical interface for working with these JSON files. The second is Lona Compiler which converts the files to UI code for various targets. Currently only React Native is supported, but more platforms are planned.
