Agents that build for you.
One prompt. Multiple specialist agents. They write code, design interfaces, fix bugs, and ship production-quality apps — together.
Watch it work
Features
Generate production code
Describe what you want — get clean React + TypeScript that follows your existing patterns and conventions.
Design with your tokens
Every component uses your Tailwind tokens. Colors, spacing, typography, and radius — all respected automatically.
Enhance rough prompts
Turn a vague idea into a detailed specification. The agent adds edge cases, accessibility, and responsive behavior.
Self-correct errors
Reads compilation errors and console output. Fixes issues automatically until the app compiles and runs clean.
Branch to explore
Fork conversations to try different approaches in parallel. Compare results side-by-side, pick the best one.
Generate themes
Create complete design token systems — light/dark mode, color ramps, spacing scales, and typography in seconds.
Audit before shipping
Check generated code for security, performance, and WCAG accessibility. Catch issues before they reach users.
Orchestrate multi-file projects
Coordinate multiple agents for complex apps. Plan the architecture, delegate tasks, verify the output.
Preview instantly
Every change compiles in the browser. See your app exactly as users will — no server, no waiting.
Works with the tools you already use
Build components while you code
Use Prototyper as an MCP tool inside Cursor. Generate entire components from your editor without switching context.
Generate apps from conversation
Claude orchestrates Prototyper agents to plan, build, and deploy — all from a single chat thread.
Preview in your editor
The VS Code extension gives you live preview, design token editing, and agent chat right in your editor.
Automate with scripts
A 20-line script that generates components nightly: fetch specs, build, test, deploy. No UI needed.
Build a custom workflow
Use the TypeScript SDK to build exactly the agent you need. Tool registry, steering, branching — your logic, your rules.
One protocol, every tool
Any app that speaks MCP gets instant access to every Prototyper tool. No custom integration code.
