Dotvault for Flask

Dotvault for Flask apps.

Flask reads .env through python-dotenv, so the file is loaded before your app ever sees it and a typo shows up as a confusing runtime error rather than a config one. Dotvault gives you a visual editor for the file, and flags SECRET_KEY when it is missing, because a Flask app that uses sessions falls over without it.

What you get

  • →Detects Flask from requirements.txt or pyproject.toml.
  • →Recognises the FLASK_APP entry point and warns when SECRET_KEY is missing.
  • →Knows the FLASK_RUN_ family for the dev server, plus DATABASE_URL and SQLALCHEMY_DATABASE_URI.
  • →Snapshot history and diff across your development and production files.

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.
