Powerful Tools at Your Fingertips

envcheck provides a suite of commands designed to handle every aspect of environment variable management, from local development to production validation.

Core Commands

• Lint: The workhorse. Scans your .env files for syntax errors, duplication, and best-practice violations.
• Compare: The team saver. Checks your .env against a reference (like .env.example) to ensure you haven't missed any new keys.
• Fix: The time saver. Automatically parses and corrects common formatting issues safely.
• TUI: The visualizer. An interactive terminal interface for exploring and comparing environment files.

Philosophy

All commands follow the Unix philosophy: do one thing well. They are designed to be composable, with standardized exit codes and optional JSON output for machine parsing.

# Example: Pipe findings to jq
envcheck lint .env --json | jq '.errors[]'
