Cookbooks
Build working apps with compact Volcano recipes, each with a tested coding-agent prompt.
Build with Volcano using focused code, a coding-agent prompt, and commands to deploy and check the result.
- Pixelboard: a shared canvas with anonymous sign-in, persistent pixels, and live updates.
- Real-time chat: anonymous sign-in, rooms, messages saved in Postgres, live delivery, an online count and typing indicators.
- Photo sharing with Storage: email sign-in, uploads to a storage bucket, browser-made thumbnails, and bucket policies that let only the uploader delete.
- Ecommerce store: a public catalog, carts in Postgres, and a function that prices each order and takes the stock in one transaction, so two shoppers can't buy the last unit.
- Notes app with per-user data: email and password sign-in, and a notes table where row-level security keeps each person's notes private.
- Petstore API from its OpenAPI spec: the Swagger Petstore spec as a live API on Postgres, with public reads, signed-in writes, and row-level security, tested from Insomnia.
- Remote MCP server with Postgres tools: an MCP server on a public HTTPS URL, with bookmark tools behind a bearer token, called from Insomnia or Claude Code.
