Putri Karunia co-founded Typedream (YC, acquired). Lunagraph is what she built next.
The idea: design on a canvas, get real code out. Not a Figma file — actual HTML, CSS, and React, written into your repo. Claude Code does the generation. There is a chat interface that understands your canvas state and your local codebase.
Launched April 2026. Public beta, free, request-access. Too early to evaluate properly — worth watching.

Alternatives to Lunagraph
Antigravity
Google Antigravity is an agentic IDE built on a forked VS Code that lets AI agents autonomously plan, write code, run the terminal, and test in a browser with minimal hand-holding. It pairs with Google Stitch (their text-to-UI design tool) to form a full design-to-code pipeline. Available free in public preview with generous Gemini 3 Pro limits; also supports Claude and OpenAI models.
Bolt.new
Browser-based AI coding platform powered by StackBlitz's WebContainer technology — a full Node.js environment running entirely in the browser via WebAssembly. Describe an app, and Bolt generates, runs, edits, and deploys it without local setup. Went from $80K to $40M ARR in five months; Bolt V2 adds cloud databases, auth, and edge functions. Powered by Claude.
Pencil
A design canvas that syncs directly to code. Pencil lives inside your IDE (Cursor, VS Code), feeds pixel-exact coordinates and design tokens to AI agents via MCP, and supports bidirectional sync — visual edits update the codebase. New: Code on Canvas lets you drop a Script node on the canvas, point it at a .js file, and render live design layers from code, with design tokens flowing in as inputs. Supports Figma import, parallel multi-screen generation, and Git-versioned design files.
Replit
Cloud-based development platform centered on AI Agent 3, which works autonomously for up to 200 minutes — testing its own code, spawning subagents, and connecting to 30+ services including Stripe, Figma, and Salesforce. Raised $250M at $3B valuation in January 2026. Best for rapid prototyping and solo builders; cost can spiral on heavy usage.
