Hey Product Hunt, I built envfix after running into a very ordinary developer problem again and again: .env.example changes, but someone's local .env doesn't — and the application fails for a reason that takes longer to find than it should. What started as a tiny checker has grown into a small environment configuration doctor for Node.js projects. envfix can: - detect missing, empty, extra, and duplicate variables - catch malformed environment declarations - check whether .env is safely ignored and untracked by Git - safely fix missing configuration - generate and sync .env.example files - work in CI with JSON output and GitHub Actions annotations It has zero dependencies and is deliberately conservative: it won't overwrite existing non-empty values or print environment values into logs. You can try it without installing anything: npx envfix I'm currently focusing on building small open-source developer tools that remove everyday friction. I'd love feedback, especially on the CLI experience and the .env problems you run into in real projects.
