How Kystral builds
Agent-native
Products speak to coding agents through local tools, with permissions you can see. An agent can search, draft and take a task. It does not get the run of the system.
Native on macOS and Windows
Where the work happens on a desktop, we ship a real client for both platforms. The stack follows the job: Swift, .NET, Tauri or Electron.
Capability
Kystral Design System
One token set drives the web, macOS and Windows. Colour, type, motion and components stay in step, and contrast is held to WCAG 2.2 AA.
- TokensColour, type and motion, shared across the product line.
- ComponentsThe same interface language on the web and on the desktop.
- ContrastBuilt and checked against WCAG 2.2 AA.
Services
Product engineering
From a sharp brief to a shipped product. Architecture, implementation, and the unglamorous work of making it fast, secure and operable.
Design
Interfaces with a point of view, and the system underneath them. Type, layout and components that hold together across a product line.
AI and systems consulting
Where a model belongs, and where it does not. Retrieval, tool use, evaluation, and the controls around them.
