Quick start

To install Dagster and Dagit into an existing Python environment, run:

pip install dagster dagit

This will install the latest stable version of the core Dagster packages in your current Python environment.

Dagster is tested on Python 3.8, 3.7, 3.6, and 2.7.

Using Python 3 is strongly encouraged, as the official EOL for Python 2 was January 1, 2020.

To check that Python and the pip package manager are already installed in your environment, you can run:

python --version
pip --version

We strongly recommend installing Dagster inside a Python virtualenv. If you are running Anaconda, you should install Dagster inside a Conda environment.

If you would like to install Dagster from source, please see the section on Contributing.


As an open source project, we collect usage statistics to better understand how users engage with Dagster and to inform development priorities. Telemetry data will motivate projects such as adding functionality in frequently-used parts of the CLI and will help us understand adoption of new features.

We will not see or store any data that is processed within solids and pipelines. We will not see or store solid definitions (including generated context) or pipeline definitions (including modes and resources).

The telemetry-instrumented functions are:


To see the logs we send, open $DAGSTER_HOME/logs/ if $DAGSTER_HOME is set or ~/.dagster/logs/ if not set (after calling the instrumented functions).

If you'd like to opt-out, you can add the following to $DAGSTER_HOME/dagster.yaml (creating that file if necessary):

  enabled: false
