Dotvault for Flask

Dotvault for Flask projects.

Flask is one of the frameworks Dotvault detects automatically. Point Dotvault at your project folder and it'll identify Flask from your package manifest, surface the common environment variables it uses, and give you the visual editor, snapshot history, and diff tools you need to manage them properly.

What you get

  • → Automatic detection of Flask from your project's manifest.
  • → Visual editor with syntax highlighting, validation, and smart warnings.
  • → Snapshot history so you can roll back any change.
  • → Diff view across environments to catch drift.
  • → Works entirely on your Mac — no accounts, no cloud, no CLI required.

Known environment variables

Dotvault recognises these variables when you open a Flask project and surfaces helpful descriptions and warnings in the editor. Flask is detected via `flask` in requirements.txt or pyproject.toml.
