envdrift

Detect missing keys, type mismatches, and placeholders across environment files.

envdrift compares two or more environment files and reports structural differences before they become deployment failures. Values stay redacted by default while type, protocol, placeholder, and presence signals remain visible.

npm package Source on GitHub

Installation

npx @barissozudogru/envdrift .env .env.production

Platform requirements and configuration are documented in the repository instructions.

Capabilities

Compare multiple .env files in one run
Find missing keys and inferred type mismatches
Flag placeholder values and protocol inconsistencies
Produce JSON output and CI-friendly exit codes

Use cases

Checking development, staging, and production configuration together
Adding an environment-contract check to CI
Reviewing drift without printing raw secret values

Evidence

redaction contract

Useful configuration differences remain visible while values stay hidden.

The default report exposes presence, inferred type, length, character class, protocol, and a stable fingerprint. Raw values require an explicit local-only flag.

Limitations

It compares configuration shape and signals, not the validity of external credentials
Files must be available to the local process running the command
Review intentionally different values before enforcing a strict CI policy
