Dotvault for Symfony

A proper .env editor for Symfony apps.

Symfony layers its environment files: .env, then .env.local, then .env.$APP_ENV, each overriding the last. Working out which file a value actually came from is a genuine chore. Dotvault opens them side by side, knows the variables Symfony and its components expect, and tells you when a required one is missing.

What you get

  • →Detects Symfony from symfony/framework-bundle in composer.json.
  • →Recognises the core set, APP_ENV, APP_SECRET and DATABASE_URL, and flags APP_SECRET when it is absent, because Symfony will not boot without it.
  • →Knows the DSN-shaped variables the components use: MAILER_DSN, MESSENGER_TRANSPORT_DSN, LOCK_DSN, NOTIFIER_DSN and the Mercure trio.
  • →Recognises TRUSTED_PROXIES, TRUSTED_HOSTS and CORS_ALLOW_ORIGIN, the ones that are quietly security-relevant.
  • →Diff .env against .env.local to see what your machine is overriding.
