Most builders stop at the template – and most AI stops at the first draft

Ferax does the whole job: generate, refine visually, check quality, publish.

Describe

Up to 3 clarifying questions before a line is generated, and a sparkle button that turns a rough idea into a full brief.

Refine

25 fonts, a gradient builder and a box-model diagram in the design panel. Or select one section and prompt changes for only that part.

Publish

30+ pre-publish checks with AI auto-fix, then one click to a live URL — or Netlify, Cloudflare Pages, GitHub, FTP, or an exported codebase.

Every tool, every model,
one editor in Ferax

Four project types, 15 models from 5 providers and a complete visual editor in one workspace.

Design Intelligence

A new era of building,
with Design Intelligence

Ferax recognises what you're building and injects the right design decisions before the first line is generated.

The best model is your model

Pick a model per project, or bring your own API keys. Every provider runs with your project's memory and design brief.

Anthropic ClaudeOpenAIGoogle GeminiDeepSeekKimiBring your own keys

Context

Per-project memory keeps the last 10 interactions, so follow-up prompts build on what came before instead of starting over.

Intelligence

Choose from Claude, GPT, Gemini, DeepSeek and Kimi models. Tokens stream in real time and prompt caching keeps iterative edits fast.

Taste

25 style presets plus Design Intelligence set palette, type pairings and section order before generation, so output matches the brief.

Built for the second draft, not just the first

Generation is the start. Everything else is about iterating fast without losing work.

Memory updated

Memory & recovery

Each project remembers its last 10 interactions, and finished generations are recovered even if your connection drops.

Connection dropped at 14:02 → generation recovered, 0 tokens lost.
15 models

Every model, your keys

Claude, GPT, Gemini, DeepSeek and Kimi in one picker. Add your own API keys and use them across projects.
