Protoyard
Real behavior. Fake infrastructure. Every prototype is an independent app with its own persistent browser database, scenarios, personas and simulated time.
Explore an idea in seconds, keep the one that works, and share it. Everything runs in the browser with simulated data.
protoyard quick turns a sentence into a running exploration in about 1.5 s, with variants to compare side by side.
Open a blueprint from a share link, a file or a pasted document. No build, and each blueprint keeps its own browser storage.
Player guideAsk for a deck on any topic and get slides you can click through, present and share: designed layouts, live charts and interactive blocks, from one JSON file.
Decks guideWhen an idea is worth keeping, generate a real Vite + Svelte 5 app from its data-only blueprint, or start from a template.
Generator guideA persistent browser database, deterministic scenarios, personas and simulated time, all under an in-app DevTools panel.
Scenarios guideThemes, layouts and device shells, plus rich views, charts, analytics, SaaS flows and scripted AI assistants.
Themes guideReviewers pin comments to screens of a built prototype or a served exploration; an agent can plan from the result.
Review comments guideA relocatable static export, a single HTML file, a private Claude artifact, or a deploy through the publish adapters.
Publishing guideA distributable agent skill, a local MCP server, a DeepWorkPlan addon and a versioned machine interface.
Agent skill guideEvery library is a publish-ready npm package with typed ESM exports. Not on npm yet: today you run Protoyard from its repository.
