Instead of pen.dev
pen.dev alternatives
pen.dev combines a vector design tool with software-building workflows. Its canvas handles components, variables, themes, scripts and shaders, imports Figma or HTML, and exports PNG, JPEG, WEBP, PDF, HTML, CSS and Tailwind. An integrated agent or MCP-connected external agents can work alongside supported AI providers. The open JSON .pen format, Chrome importer and IDE extensions suit teams moving between design and development. It runs through web, macOS, Windows, Linux, API and extension platforms.

Readers may still look elsewhere because pen.dev's current free tier allows five Agent days, 25 image or SVG generations each month and one agent at a time. Pro is $16 per user monthly and Ultra is $48, while broader plans are coming soon. Alternatives emphasize different outcomes: conversational prototypes, collaborative planning, code-based wireframes or deployed applications. Weigh whether you need production code, visual mockups, shared canvases, declarative files or mobile access, then compare exports, integrations, agent capacity and pricing.
