Environment Tools
4 free Environment tools — all run locally in your browser.

Check a .env file for the dotenv parsing gotchas that silently corrupt values — # truncation, duplicate keys, unclosed quotes.

Convert a .env file to a YAML mapping, with every value safely quoted so it round-trips as a string.
YAML to .env
Convert a YAML mapping (or a Compose-style KEY=VALUE list) to a .env file, with every value safely quoted.
Environment Variable Diff
Compare two .env files — catch a variable your template declares that never got set, or a value that quietly drifted.
