Dotvault vs dotenv

This is almost not a comparison. dotenv is a library — something you install in your project that reads a .env file at startup and loads its values into the application’s environment. Dotvault is a desktop app that helps you edit those same files. If you use dotenv (or any of the language-specific ports — python-dotenv, godotenv, dotenv-rails, and so on), Dotvault is the tool for handling the file itself. They’re not in competition. One runs in your app, the other runs on your desk.

Replaces .env files?	No — works with them	No — reads them
Best for	Local editing workflow	Application runtime

Library versus editor

dotenv (or whichever language-specific version you’re using) does one small, useful thing: at app startup, it opens .env, parses each KEY=VALUE line, and sets those as environment variables your code can read via whatever the standard mechanism is — process.env.FOO in Node, os.Getenv("FOO") in Go, ENV['FOO'] in Ruby. You never actually see dotenv doing its work. It runs once, quietly, then gets out of the way.

Dotvault is a completely different kind of tool. It’s a GUI that opens when you want to look at or edit a .env file. Snapshots so you can see what the file looked like an hour ago. Side-by-side diffs. Inline notes on each variable so you remember what it’s for. Framework awareness so it understands the conventions of the .env files in Laravel, Next.js, Rails, Django, and the rest. Encryption at rest so the file on disk isn’t readable without your macOS login.

They don’t overlap because they’re addressing different moments. dotenv answers “how do I get the values from this file into my running program?” Dotvault answers “how do I manage this file without creating a mess?”

What each one does for you

If you’re already using dotenv (or python-dotenv, or any equivalent), you probably don’t think about it often. It just works. When you add a new variable to .env.local, the next time you run the app, that variable shows up in process.env. That’s the entire interaction.

Dotvault’s contribution sits earlier in the loop. When you’re actually editing that file — adding a new API key, changing a database URL, working out why staging broke — Dotvault is the tool that makes that editing experience less painful. It remembers every previous state of the file. It shows you what’s changed between any two versions. It tells you when an .env.example in the repo has added a variable your local .env is missing. It stops you from accidentally deleting half the file, because undo goes much further back than the five minutes your editor’s undo buffer remembers.

That’s the split. dotenv is about the runtime. Dotvault is about everything that happens before the file hits the runtime.

Using both together

This is the normal case, not the weird one. A typical project has require('dotenv').config() somewhere near the top of its entry file, and developers working on that project will use whatever editor they happen to prefer for .env changes. Dotvault is what I’d reach for instead of VS Code or vim when I’m specifically editing .env — because it’s purpose-built for that job and knows things a general editor doesn’t.

dotenv doesn’t know or care what opened the file. As long as the file is on disk, in the expected format, it’ll load it. Dotvault writes .env files in exactly the format every dotenv implementation expects, preserves comments and blank lines, and respects things like the export prefix that some dotenv variants accept.

There’s no “migrate from dotenv to Dotvault” because migration isn’t a concept that applies. They’re not the same kind of thing.

Who should use which

If you’re looking for a way to get values from a .env file into your running application, dotenv (or the equivalent for your language) is almost certainly what you want. It’s free, it’s tiny, it’s universally understood, and it’s what practically every project is using already.

If you’re looking for a better way to work with those .env files on your Mac — edit, diff, snapshot, restore, annotate — that’s what Dotvault is for. It sits next to whatever dotenv you’re using without caring which one or getting in its way. Install it, point it at your projects, and the runtime side of your setup doesn’t change at all.

Most developers will end up using both without really thinking about it. dotenv will keep quietly loading the file at startup. Dotvault is what you open when the file itself needs attention.
