| Data handling | Only the prompt and skill context are sent to the provider whose keys the user supplies, and OpenDesign says it has no server of its own. | Text AI requests using a user's own provider credentials go directly from the device to that provider, while hosted-model requests pass through High Agency infrastructure in real time. |
| What it does | OpenDesign is an agent-native workspace that turns coding agents into a workflow for generating prototypes, websites, dashboards, decks, images and HTML video. | pen.dev is an AI-assisted design editor where agents create or modify vector designs on a canvas and users can export the result to code. |

In their own words
OpenDesign
OpenDesign is an open-source AI design workspace that uses local coding agents to create runnable design files. It can produce prototypes, landing pages, slide decks, dashboards, brand systems, images, and HTML video, with clickable prototypes and HTML or code exports. The site lists 152+ design systems and a library of templates and skills. OpenDesign supports 17 first-party bring-your-own-key adapters, including Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot CLI, OpenCode, and Qwen. Its API can also be used with Codex, Claude Code, DSH, OpenCode, and Hermes through an OpenDesign API key. The desktop app, daemon, and skill runtime run on the user’s machine, and generated files are stored in the project directory. OpenDesign says it has no server of its own; prompts and skill context go to the provider associated with the keys the user supplies. The app supports macOS 11 or newer on Apple Silicon or Intel, and Windows 10 or 11 x64. The free plan is local CLI plus BYOK, with no recurring OpenDesign model-credit grant; paid plans start at $5/user/mo.
pen.dev
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.
