You already pay for one AI tool. This one makes it design for you, and costs nothing.

OpenDesign is the open-source alternative to Claude Design β€” a local-first desktop app for macOS and Windows that hands the design job to the coding agent already running on your machine.

:link: github.com/nexu-io/open-design β€” Apache-2.0, 93.6k stars, 10.7k forks.

No new subscription. It works BYOK, driving what you already have: Claude Code Β· Codex Β· Cursor Β· DeepSeek Harness Β· Qwen Β· Copilot Β· Kimi and 26 local command-line agents, or any OpenAI-compatible endpoint.

And it gives you real files, not share links: HTML Β· PDF Β· PPTX Β· MP4, saved on your own disk.

🎨 What it builds
  • Prototypes β€” web, desktop and mobile, previewed in a sandboxed frame before anything is exported.
  • Live dashboards and artifacts β€” working pages, not flat mockups.
  • Slide decks β€” straight out as .pptx, ready to open and present.
  • Images and video, plus HyperFrames motion graphics for the moving pieces.
🧩 The part that makes it yours β€” DESIGN.md

Your brand written as a plain file the agent reads: colours, type, spacing, rules. Every artifact it builds afterwards comes out in your design system instead of generic AI styling.

Around it sit composable skills, rendering templates and plugins β€” a folder of capabilities your agent can read, write and remix, rather than a closed feature list somebody else decides for you.

Why it matters: the loop Claude Design keeps behind a paywall β€” discover the brief, lock the direction, stream the artifact, critique it, deliver β€” is here as an open filesystem your own agent drives. The intelligence you already pay for; this gives it hands. :hand_with_fingers_splayed:

i hope it benefits all the community

Local-first is the part I like most here β€” handing the design job to the agent already running on your machine is smarter than paying for yet another subscription. The DESIGN.md idea is worth stealing even on its own; a single file with your brand tokens and layout rules cuts out so much back-and-forth. I am curious how it handles iteration though, since design work is usually a feedback loop rather than one-shot generation.
