Open Source · Apache-2.0
From idea to prototypes, websites, slides, and HTML video — the entire product design workflow, on your own machine.
Apache-2.0 · Runs locally · BYOK · No sign-up
Part 01
In April 2026, Claude Design proved for the first time that LLMs can genuinely design — but it's closed source, paid, and cloud-only. Open Design sets that capability free.
Core Capabilities
Reads local files, Figma exports, and code repos directly
Auto-detects CLIs on your PATH — zero config
Import from GitHub / Figma / local files
Anthropic / OpenAI / Azure / Google + 14 media providers
It doesn't build an agent — it wires the Claude Code / Codex / Cursor on your machine into a complete design workflow.
Local-first
$ git clone github.com/nexu-io/open-design
# .od/ — all runtime data lives on your machine .od/ app.sqlite # local SQLite, no cloud dependency projects/ # agent working directories artifacts/ # saved render artifacts media-config.json # BYOK credentials, never uploaded byok: providers: [anthropic, openai, azure, google] self_host: true # Apache-2.0, self-host freely
Cost Race
monthly cost ($500 → ~$73)
coding agents connected
plugins in the ecosystem
Workflow
One sentence / template / plugin
Palette & fonts auto-applied
Artifacts in a live sandbox
Hand off to engineering or render video
Every choice settles into design systems, preferences, and memory — each generation lands closer to what you want.
