What OpenStitch is
OpenStitch is a free, open-source tool for turning text prompts, screenshots, or sketches into rendered, interactive frontend code. It is designed to run locally, with Docker, Docker Compose, and Ollama required for the documented quick start. Users can describe a screen in natural language to generate HTML, or use a vision model to create code from a screenshot or rough wireframe. More than 50 brand design systems are available, and users can also ask AI to create one from a description. Its infinite canvas lets users arrange screens, connect them into flows, and preview them in Play Mode with simulated click navigation. Screens can be downloaded as a ZIP containing DESIGN.md and individual HTML files. The project supports HTML and Tailwind CSS, responsive code, and Ollama or OpenRouter; OpenAI, Anthropic, and Gemini are wired up but described as untested. It stores data in SQLite through a Docker volume and is licensed under MIT.
Good
- Accepts text prompts, screenshots, and sketches.
- Offers more than 50 brand design systems.
- Exports screens as a ZIP of HTML files.
- Supports responsive code and Tailwind CSS.
- MIT-licensed and open source.
Watch out
- Quick start requires Docker, Docker Compose, and Ollama.
- No authentication; public exposure of ports 3000 or 7001 is discouraged.
- No multi-user collaboration; SQLite is unsuitable for concurrent access.
- Play Mode does not generate real router code.
Who it suits
OpenStitch suits people drawing web UIs with local language models, especially those who want to turn prompts, screenshots, or wireframes into HTML and arrange screens on a canvas. Its setup and security model favor local or private-network use.
Verdict
OpenStitch brings local AI-assisted screen generation, canvas-based flows, and HTML export together. Its single-user design, setup requirements, and preview limitations are important to weigh before using it for a shared or production workflow.
