In their own words
Mowgli
Mowgli is an AI design canvas for mobile, web, and desktop apps, aimed at builders shaping a product before implementation. It can generate high-fidelity screens, flows, and states, and turn an idea into a product requirements document with screens, features, and user flows. Moodboards offer 16 or more visual styles, with color palettes and typography moods. Designs can become interactive prototypes with navigation and transitions. Users can import Figma designs for AI editing and export to Figma, React components, or an AI-ready package. MCP connections let Claude, Codex, Cursor, and other compatible apps move designs and product screens between Mowgli and a codebase. A free plan includes 300 credits, Figma import, coding-agent connection, and full version history. Annual-billing plans are listed at $12.00 per month for Starter, $20.00 per month for Pro, and $49.00 per month for Team. Team adds real-time canvas collaboration and person-attributed version history; unused credits expire under subscription or credit-pack billing rules.

pen.dev is a canvas for building software and a vector design tool integrated with development environments. Its editor works with components, variables, themes, scripts and shaders, and can import Figma files and HTML. It can export to HTML, CSS and Tailwind, as well as PNG, JPEG, WEBP and PDF. Users can work with its integrated agent or connect external agents through MCP; the available plans specify how many agents can run in parallel. Documented integrations include Claude Code, Codex, Gemini CLI, Antigravity, OpenCode, Kiro and Claude Desktop. Integrated provider options include OpenAI, Anthropic, Google Gemini, Cursor, GitHub Copilot, xAI, OpenRouter and other API-key providers. Its.pen design file is open JSON with an open schema. Tools include a Chrome extension for importing webpages, IDE extensions and an npm-installed CLI requiring Node.js 22.19 or later. The pricing page says pen.dev stays free until plans launch. The Free plan is free; Pro is $16 a month; Ultra is $48 a month.
