Sandcastle — watch an AI team build a running app, live
Describe an app and a GitHub Copilot multi-agent team —
Planner, Builder and Fixer —
plans it, writes the files, runs it, and self-heals its own build errors against a
real validator, streaming a live preview you keep iterating on by chat.
Sandcastle is a live showcase for the GitHub Copilot provider for the Microsoft
Agent Framework. It runs entirely on Azure free tiers.
- Real execution — agents run, build, and test the app they write.
- Browsable source and a live preview: the artifact is real, not vibes.
- Grounded in current docs via the Microsoft Learn MCP server.
This app needs JavaScript to run interactively.
