Quickstart

Get a full alexandr runtime running on your machine, then point an app at it.

You'll need Docker, plus Node 20+ for npx.

Run a runtime

npx alexandr up

This pulls the published runtime image, boots it, and prints your workspace URL plus a desktop-app connect link. Open the URL and create your owner account — the runtime owns its own login, so you're the only one who can claim it.

Turn on the assistant

The assistant routes through xrouter, which owns credentials and spend — the runtime stores no AI key. Point it at a specific xrouter (defaults to the public one) or pick a default model:

alexandr config set ai.url https://api.xrouter.so/v1   # which xrouter (optional)
alexandr config set model  …                           # default model (optional)

Build against it

With a runtime up, you're ready to build. Continue to App anatomy to ship your first app, or Skill anatomy to add a assistant skill.
