What it solves

This project provides an open-source AI-powered poster design tool that allows users to create professional visual content—such as e-commerce images, article long-images, and social media covers—without needing deep design skills or complex software installation.

How it works

It uses a native DOM canvas editor on the frontend (Vue3) and a hybrid rendering approach where images are generated either on the client side via html2canvas or on the server side via Puppeteer and sharp. It integrates AI capabilities for image generation, copywriting, and background removal (using onnxruntime-web and the u2netp model for browser-side matting).

Who it’s for

• Individual developers looking to build or integrate a design tool into their own applications.
• Content creators who need quick, high-quality graphic layouts for marketing and social media.
• Businesses requiring a self-hosted, customizable image generation platform.

Highlights

• AI-Integrated Workflow: Built-in tools for AI image generation, AI copywriting, and one-click AI background removal.
• PSD Import: Supports parsing PSD files to help users quickly generate editable templates.
• ## Full-Featured Editor: Includes advanced text effects (shadows, strokes, gradients), layer management, and a stylized QR code generator.
• Complete Management Backend: Comes with a full admin panel to manage templates, assets, fonts, and AI API configurations (compatible with OpenAI-format interfaces).
• Production-Ready: Includes user authentication, work saving/loading, and a SQLite database for persistence.
