envdiff

Compare, validate, and sync .env files across environments.


          $ brew install shahadulhaider/tap/envdiff

Go CLI for comparing, validating, and syncing .env files across development / staging / production environments.
TOML schema validation, secret masking, matrix view across N files, git-diff integration, and interactive sync TUI.
Plays nicely with pre-commit hooks and emits GitHub Actions annotations so missing-secret bugs surface in PRs, not at 2 AM in prod.

Why it exists

Every team I have worked with has lost time to “it works on my machine because I have a secret you don’t.” envdiff makes the comparison explicit:

envdiff diff .env .env.staging .env.production
envdiff validate --schema env.schema.toml .env
envdiff sync .env .env.staging

Useful primitives:

Schema-validated env files — define required keys, types, and patterns in TOML; fail-fast in CI.
Matrix view — render N env files side-by-side; spot missing keys instantly.
Pre-commit integration — fail commits that diverge a .env.example from .env.
GitHub Actions annotations — drift shows up in the PR diff UI.
Secret masking — values redacted in output unless --show-values.
Interactive sync TUI — Bubble Tea-driven merge resolver.
