Open DesignDemo Day · Batch W26

The design tool
built for the agent
era.

Every coding agent already on a developer's desktop can now design, too. Open, local, and already inside 64,000+ repos.

The problem

Claude Design proved an LLM can truly design. But it is closed-source, cloud-only, and locked to one model. Every solo builder and design agency we interviewed is stuck paying for a tool that can't touch their own files.

Open Design puts that capability in every agent's hands.

Point Claude Code, Codex, or Cursor at Open Design and it designs like a senior product designer, on your own machine, without lock-in.

  • 01Describe a goal in one sentence, or start from a template
  • 02The agent already on your machine reads files, Figma, and repos
  • 03Real runnable files appear in a live sandbox, not a mockup
  • 04Ship straight to engineering, or export it as a marketing video
  • 05Every decision compounds into reusable design memory

Three reasons this is a wedge, not a feature.

A

We activate on day one

21 coding agents are already installed on millions of developer machines. Open Design switches on the moment it's installed: zero new login, zero seat to sell against.

B

Plug in agents, don't rebuild them

Claude Code, Codex, and Cursor already do the reasoning. We only had to build the design-native runtime around them: a fraction of the surface area of a foundation-model competitor.

C

Taste compounds against leaving

Every session writes to a local design-system memory. Thirty days in, a team's install knows their brand better than a new hire would; the switching cost rises every week they stay.

An ecosystem, not just an app.

64K+
GitHub stars in 11 months, Apache-2.0, zero paid marketing
220+
plugins shipped by the community: prototypes, slides, dashboards
340

21
coding agents auto-detected from PATH, zero config

Claude Code, Codex CLI, Cursor Agent, Gemini CLI and more. Any OpenAI, Azure, or Google-compatible endpoint works via BYOK.

BYOK makes our moat structural.

Claude Design

$500

per seat, per month. Closed cloud subscription, one vendor, one model.

Open Design Cloud

~$79

per seat with BYOK. We only charge for orchestration; model spend goes straight to the provider, at cost.

Apache-2.0 licensed. Fork it, self-host it, run it fully offline: the moat is the agent integrations and design memory, not a paywall.

"Our whole team ships client mockups through Claude Code now. Open Design is the only tool that lets our agent touch the real Figma file and hand back real code."

The ask

Raising $2.5M
to own the wedge.

18 months of runway to take Open Design Cloud from $81K to $500K MRR while the agent-native design category is still undefined.

$2.5M
seed, SAFE, $18M post-money cap
18 mo
runway to Series A
$500K
