sqt dev

Compile a project, connect to its selected ClickHouse target, and serve the packaged web UI and JSON API until interrupted:

sqt dev
sqt dev --project-dir examples/orders_demo
sqt dev --ui-host 127.0.0.1 --ui-port 8000

Open http://127.0.0.1:8000 by default. sqt dev accepts the normal project, target, variables, and ClickHouse connection overrides in addition to:

Option	Purpose
--ui-host VALUE	Bind interface; defaults to 127.0.0.1
--ui-port VALUE	Bind port; defaults to 8000
--auth-mode VALUE	disabled, trusted_proxy, or password
--control-store-url VALUE	SQLite or PostgreSQL account store

The UI combines authored definitions with live warehouse state. Detailed guides cover each workflow:

Development UI

Start with the page map, snapshots, and operating model.

Warehouse Health

Inspect ClickHouse capacity, memory context, and current activity.

Sources

Inspect landing health, retention, freshness, and Kafka lag.

Messages

Search records retained in ClickHouse without consuming Kafka.

Plans

Preview warehouse changes and launch builds.

Runs

Inspect durable execution, cancellation, and recovery.

Quality

Run tests and audits and monitor the audit scheduler.

Disabled authentication is limited to loopback. See Authentication before exposing the server, then define operational permissions with Access Control.
