OpenPencil
Open-source AI-native design editor with native Figma file support
Free Design Open Source
Overview
OpenPencil is an open-source, AI-native design editor that works as a local Figma alternative. It opens and exports native .fig files with round-trip fidelity via the Kiwi codec, runs entirely offline with no account or server required, and includes built-in AI chat with tool use for design assistance. The ~7 MB Tauri-based desktop app supports real-time P2P collaboration via WebRTC, a headless CLI for scripting and automation, and a programmable JSX renderer. Bring your own API key for AI features with no vendor lock-in.
