# Build

Develop Cyoda applications — tier-agnostic patterns that work on any runtime.

Cyoda applications are **digital twins**: the same code runs on every
storage tier, from in-memory dev through Cassandra at enterprise
scale. Pages in this section cover the patterns — entity modeling,
workflows, external processors, testing — independent of where your
app runs.

## Build with a coding agent

Building with Cyoda is easiest with an AI coding assistant. The Cyoda Skills plugin drops in
to Claude Code, Cursor, Codex, and other compatible tools, giving them
the skills to set up a local instance, model entities, design
workflows, and run tests against your Cyoda app. Install it from
github.com/Cyoda-platform/cyoda-skills
and let your assistant lead — the rest of this section is the manual
reference behind what the skills do.
