How to Create and Manage .env Files

Build organized .env files with grouping, comments, and TypeScript types using The IT Hustle's free Env File Manager.

1
Start from a presetLoad a Next.js + Supabase, Stripe, Database, OAuth, or AWS preset to scaffold the variables those stacks expect.
2
Add your variablesEnter each key and value — keys are auto-uppercased and validated, and values with spaces are quoted automatically.
3
Organize with groups and commentsAssign variables to named groups and add per-variable comments so the file documents itself.
4
Switch output tabsView the full .env, a values-stripped .env.example for your repository, or generated TypeScript type declarations.
5
Copy or downloadCopy any of the three outputs to your clipboard or download them as files.

Frequently Asked Questions

It's a committed template listing every environment variable your app needs — with the values stripped out. New teammates copy it to .env and fill in their own secrets, so the required keys are documented without leaking credentials.

No. .env files contain secrets and belong in .gitignore. Commit the generated .env.example instead — it documents the keys without the values.

The tool generates a .env.d.ts declaration file typing each variable on process.env. Your editor then autocompletes variable names and TypeScript catches typos like process.env.DATABSE_URL at compile time.

No. Everything is generated in your browser — keys and values never leave your machine, which is exactly what you want when handling API keys.

Environment variable keys must start with a letter or underscore and contain only letters, numbers, and underscores. The tool validates this as you type so the file works in every shell and runtime.
