Getting help

View help for any command by adding --help:

Authentication

Authenticate with Runpod:

flash login

This command opens your browser to authenticate with Runpod. After you approve the request, your API key is saved locally for future CLI operations. See flash login for details.

Alternatively, set the RUNPOD_API_KEY environment variable:

export RUNPOD_API_KEY=your_api_key_here

Using uv

If you installed Flash with uv, prefix all Flash commands with uv run:

uv run flash login
uv run flash dev
uv run flash deploy
