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 — a **local-first desktop app** for macOS and Windows that hands the design job to the coding agent already running on your machine.

🔗 **[github.com/nexu-io/open-design](https://github.com/nexu-io/open-design)** — Apache-2.0, **93.6k stars** , 10.7k forks.

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

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

> **🎨 What it builds**
>
> - **Prototypes** — web, desktop and mobile, previewed in a sandboxed frame before anything is exported.
> - **Live dashboards and artifacts** — working pages, not flat mockups.
> - **Slide decks** — 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 — 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 — 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 — discover the brief, lock the direction, stream the artifact, critique it, deliver — is here as an open filesystem your own agent drives. The intelligence you already pay for; this gives it hands. 🖐

i hope it benefits all the community

Local-first is the part I like most here — 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.
