Subframe

Subframe

Subframe is a macOS app that merges a design canvas, a coding agent, and a built-in browser into a single workflow for building web applications. It allows designers and developers to visually design using HTML and React components, preview live apps, and implement changes directly in the codebase using agents like Claude Code or Codex. The tool eliminates context-switching between design and development tools. Key capabilities include an infinite canvas for design exploration, a built-in browser for live preview and element inspection, and an integrated coding agent for generating or modifying code. It supports components, design tokens, themes, and multiplayer collaboration. Subframe is built for teams and individuals who want to ship web projects faster with higher fidelity, maintaining a single source of truth between design and code.

Product information

Everything worth knowing about Subframe

The complete picture — from everyday features to the technical detail builders and IT folks dig for.

Core features

What it actually does

Design Canvas
Infinite canvas for interface design, fully synced with your codebase. Drag & drop, layers, and inspector with HTML/React as the design material.
Built-in Browser
Preview and edit your live app directly in Subframe. Inspect elements, tweak design tokens, and capture components from your running localhost.
Coding Agent Integration
Connect your Claude Code or Codex subscription to have an agent that can implement designs, fix bugs, and create variations directly in your codebase.
Real-time Collaboration
Share canvases with your team or agent for multiplayer editing, commenting, and code review on design explorations.
Technical capabilities
1:1 Code Mapping
Every design layer maps directly to code elements (e.g., React components) for responsive flex behavior, enabling seamless handoff without translation.
MCP Server
Supports connecting external agents like Cursor or Gemini via Model Context Protocol for extended functionality.

Subframe 101: Getting started with design, code, and AI
Start building → https://subframe.link/3HiSWx8 In this Subframe tutorial, Filip, designer co-founder of Subframe, walks through the full design-to-code workflow — from setting up your theme and components, prompting AI, editing designs, and exporting React + Tailwind code. Subframe is the AI design tool with real components and code export. Build visually with drag-and-drop or Ask AI — all using your design system. Intro - 0:00 Projects - 0:22 Customizing components - 0:32 Edit theme - 0:54 Design with AI - 1:10 Design mode - 2:25 Contextual edits - 2:53 Insert with AI - 3:12 Code export - 3:30

Subframe Tutorial: Designing an MVP with AI (Full Workflow)
Get started → https://subframe.link/yt This is a full MVP design walkthrough — using AI inside Subframe to build real, clean UI that devs can ship. We’ll design User Stories: a daily feedback feed that shows what users are trying to do. You’ll see structure-first thinking, judgment, and actual React output — not just prompts. In this video, Jeff designs a full MVP inside Subframe — with AI supporting real design decisions, tradeoffs, and follow-through. We’re building User Stories: a product for teams to review user–AI conversations, spot what users are trying to do, and build a habit of friction-hunting. This is a structure-first, judgment-heavy workflow — not a prompt demo. Every component and design resolves to clean React you can hand off or ship yourself. What you'll see: - How to set up a Tailwind-based design system with tokenized themes - Using AI to scaffold structure, not just polish UI - Live walkthrough of component editing, variants, props, and slots - Designing for real dev handoff (not Figma hand-waving) - Judging when to use AI, and when to push it aside What this is not: No prototyping No code shipping (yet) — this is what happens before the commit If you care about product structure, team handoff, and making AI useful instead of noisy — this workflow is for you.

What's great
  • Seamless design-to-code workflow in one app
  • Built-in browser for live app preview & editing
  • Works directly with your Claude Code/Codex subscription
Technical strengths
  • Design canvas material is native HTML & React
  • Direct 1:1 code mapping for responsive flex behavior
  • Agent reads browser DOM & underlying codebase files
Where it falls short
  • macOS only for desktop app
  • Optimized primarily for React stacks
  • Full feature set requires paid Pro plan
Technical limitations
  • Cloud-based canvas means design state isn't fully local
  • Agent behavior is dependent on connected model's capabilities
