OpenPencil is an open-source design tool that aims to provide an alternative to Figma, particularly for solo UX/UI designers and small teams. Unlike Figma, which has a subscription model and relies on external tools for AI functionalities, OpenPencil integrates its AI capabilities directly into the design canvas.
What is OpenPencil?
OpenPencil is a design editor licensed under the MIT license, currently in active development since early 2026. Built on CanvasKit and the Yoga layout engine, it is designed to be lightweight, with a desktop application size of only 7MB, running on Tauri. It is important to note that there are two unrelated projects with the name OpenPencil; the one discussed here can be found at openpencil.dev and GitHub’s open-pencil/open-pencil.
Core Features and Functionality
OpenPencil supports a range of features that are essential for UI design, including a vector editor with components, auto-layout, and peer-to-peer collaboration. It can read and write Figma’s .fig files using the same Kiwi binary codec, allowing for seamless integration of existing Figma projects. Users can copy and paste elements between Figma and OpenPencil without losing fidelity, maintaining all attributes such as fills, strokes, and layout properties.
AI Integration and Usability
The standout feature of OpenPencil is its integrated AI, which can be activated using Ctrl + J. Users can connect their own API key from various providers, including OpenAI and Google AI, allowing for a customizable AI experience. This AI operates directly within the design workspace, enabling users to perform tasks through natural language prompts. The AI’s actions are logged in a collapsible timeline, providing transparency and an undo option for all operations.
While OpenPencil does not yet support advanced prototyping or a plugin ecosystem, it offers a robust set of tools for solo designers. The AI’s performance is contingent on the chosen model, and users have reported varying experiences based on their API integrations.
Conclusion
Although OpenPencil is still in its early stages and lacks some features found in Figma, its integrated AI and open-source nature make it a compelling option for those seeking a cost-effective design solution. As development continues, it may become a more viable alternative for a broader range of design workflows.
