UI With Speed of AI AndThe Taste of a Designer

We sweat the details, so you don't have to. Hundreds of beautiful UI components, plus AI that generates new ones.

How It Works

From components, design systems to the whole product

No AI slop: every component is generated against your design system, reviewed, validated, and shipped as code, over MCP or to Figma.

How Atheros turns a prompt into a shipped componentGenerate a component from a prompt or a screenshot you upload, or start with one of the UI component templates. Atheros AI — the Atheros router — weighs complexity, cost and quality to run each request in one of three modes: Auto for the best fit, Ultra for the most beautiful UI, Flash for results fastest. A single component is built against a design.md and validated for tests, accessibility and design tokens; a project holds many components under that same one design.md, with builder.md alongside it. Either one ships three ways: exported code as React, vanilla or TypeScript, AI agents such as Claude Code, Codex and Cursor over the Atheros MCP, or Figma with auto layout.GenerateModifyCreate newPromptScreenshotUI Gallery300+componentsAtheros AIComponentProjectsdesign.mdtokens, type, spacingbuilder.mdstack, rules, patternsExport codeVanillaReactTailwindTypeScriptAI agentsClaude CodeCodexCursorFigma

Pull Components With AI Agents

Connect Claude Code, Cursor or Codex to the Atheros MCP and let your agent work with your components directly.

Build High Quality Frontend With 340+ Production-Ready Components

Search our growing UI collection with search_components. Your agent finds the template that fits and writes it into your project directly over the Atheros MCP, with the component context and your design system applied automatically.

Your Own Private UI Collection

Generate a whole private component library, then pull it back into any project with get_component — the same way you reach for a catalogue template.

Validate Against Design.md and Builder.md

validate_project runs the automated tests and checks the output against your design system. Your Builder.md guidelines keep every component in line with the rest of your project.

Export directly to Figma

Copy any component in the builder and paste it into the Atheros Figma plugin. It lands as real Figma layers — auto-layout, text and styling intact — so your design team works from what was actually built.

Real Layers & Auto-Layout

Every element arrives as a named layer inside auto-layout frames, with hug and fill sizing read from the rendered component — nothing is a flat image.

Styling Carried Across

Colors, gradients, shadows, corner radii and typography come through as they render. Fonts are matched to what your Figma has installed.

Every Breakpoint, or Exactly This View

Get a clean frame at mobile, tablet and desktop, or copy the current view — open menus, filled forms and all — at the width you're previewing.

Note from founders

AI components and systems with real engineering and design behind them

Atheros Builder is created by three brothers from the product design and engineering industry — two developers and one designer who understand how real digital products are planned, designed, built, and shipped.

We built Builder because you don’t need more random AI output. You need components that feel on-brand, polished, responsive, and practical enough to use in real products.

With years of experience across design systems, frontend development, AI workflows, and product education — plus a community of more than 1M followers across our channels — we’re building Atheros Builder around the way you actually work: from idea to design, code, iteration, and production-ready UI respecting your current tool stack.

No AI slop. Just better components, faster.
