From the project root, run:

uv run dg dev

The uv run command runs dg dev in the isolated project environment defined by pyproject.toml.

When the logs show that the Dagster UI is available at http://127.0.0.1:3000, proceed to the next step.

Note

dg dev uses an ephemeral Dagster instance by default. To preserve run history, set DAGSTER_HOME before starting the server.

$env:DAGSTER_HOME="$env:USERPROFILE\.dagster_home"
uv run dg dev
export DAGSTER_HOME=~/.dagster_home
uv run dg dev
