How Caliu Works

What happens behind the screen: where your notes live, how sync works, and how each app is built.

  • Caliu under the hoodThe big picture: your devices, Caliu's server, and how the pieces fit together.
  • Where your notes liveA real database on every device, the same one on the server, and Markdown as the format underneath it all.
  • Inside syncHow a change travels from one device to the rest: a queue, a change log, and a careful merge when two devices disagree.
  • The serverWhat runs in the cloud: a small TypeScript service on Cloudflare's network that relays your changes and serves the API.
  • Native apps, not a wrapperEach Caliu app is built with its own platform's tools, so it feels at home wherever you write.
  • The editorsHow each app turns plain Markdown into the page you write on, using the text engine its platform was built around.
