# kuilt

> kuilt is a Kotlin Multiplatform library for apps whose devices talk to each other — phones, browsers, desktops and servers. It gives them one way to find each other and pass messages over whichever connection is available, shared data that stays in sync when two people change it at once or one of them was offline, and — where everyone has to agree on one order of events — a leader and a shared history. The same application code runs over a relay server, a local network, a direct link between two nearby phones or a browser connection, and over two peers or twenty.

If you are a coding agent writing networking, session or shared-state code against kuilt, read the cookbook first. It is a lookup table from the thing you are about to hand-roll — a reconnect loop, a heartbeat, a seen-ids set, a merge rule — to the kuilt primitive that already does it, with a compile-checked snippet for each.

Targets: JVM, Android, iOS, macOS and wasmJs. Every module below is published to Maven Central as `us.tractat.kuilt:<module>`; import `us.tractat.kuilt:kuilt-bom` once and then declare modules without versions. The README links the current release.

Links to `raw.githubusercontent.com` are markdown source; links to `https://tractat-us.github.io/kuilt/` are the rendered guide and the generated API reference.

This file is generated from the repository by `.github/scripts/llms-txt.py` — from the cookbook's own headings, the guide's table of contents and the published modules' descriptions. Edit those, then re-run it; do not edit this file by hand.
