📋 JSON/YAML Diff & .env Validator
Find structural differences in JSON/YAML or validate environment variables.
The structures are semantically identical.
Guide & best practices
Env Diff for configuration and environment comparison
Spot differences between two environments – missing keys, extra variables and diverging values, with masked secrets.
Typical use cases
Useful for reconciling staging/production, onboarding new environments and finding forgotten variables.
How Balou compares environments
Paste two configurations; Balou compares keys/values locally and masks detected secret values in the display.
Env file best practices
Keep a .env.example as reference, check missing keys before deployments and never commit real secrets.
Frequently asked questions
How do I compare two .env files?
Paste both contents; Balou shows missing, extra and value-diverging keys side by side.
Are secrets masked?
Yes, detected secret values are masked in the display so sensitive data is not shown openly.
Which formats are supported?
Classic .env files as well as JSON and YAML configurations.
Do my data leave the browser?
No, the comparison runs locally; your configurations are not uploaded.
