Edit the table below — click any cell to change it. Data Viewers and the Data Sources blocks read from this.

or a locked-down browser it will not be there.
Or run Ollama on this computer:
Install it from ollama.com.
Pull a model: ollama pull llama3.1 (or qwen2.5-coder).
Blue Print runs from a file, so let it in: OLLAMA_ORIGINS=* ollama serve
Windows: set OLLAMA_ORIGINS to * in Environment Variables, then restart Ollama.

Projects
Projects in the list below are kept in this browser, on this device. To keep a project outside the browser — to back it up, move it to another computer or share it — use Save As to write it to a JSON file, and Restore to open one back up.
Templates
Ready-made starter apps. Click one to open it — it loads straight onto your canvas, fully designed and wired, so you can preview it and start editing right away.
App settings
These travel with your project and are baked into the app you download.
