Query is a one-file system that uses SQLite to cover most of the full-stack development and infrastructure needs for small websites.

Query Mental Model

This is a mental model to guide you when working with Query.

1. I do not need a database server (PostgreSQL or MySQL), as I can connect to my SQLite databases remotely using the Query APIs, the CLI, and the functions.
2. I do not need a JavaScript runtime (NodeJS, Deno, or Bun), as Query offers its own.
3. I do not need a JavaScript backend framework (NextJS, Remix or Astro), as Query provides functions to serve Pages and APIs.
4. I do not need a caching system (Redis) for my function, as Query caches them in SQLite and serves them.
5. I do not need a storage system (S3) for my assets, as Query stores them in SQLite and serves them.
6. I do not need a scaffolding tool to generate code, as Query offers its own.
7. I do not need to develop a back office admin area, thanks to the Query generator, as I can build one just by executing a command.
8. I can deploy in a couple of seconds to Query.
9. I can distribute it in multiple regions, thanks to Fly.io and LiteFS.
