How is envin different from other existing solutions?

process.env

Validating envs are quite easy and can be done in a few lines of code. You can also infer the result from the validation onto your process.env object to benefit from autocompletion throughout your application as explained in this video.

import {  } from "zod";

const  = .({
  : .(),
  : .(),
});

.(.);

declare global {
  namespace NodeJS {
    interface  extends .<typeof > {}
  }
}

const url = ..;
const url: string

Although, it's missing a few important features like extendable presets, differentation of server and client envs, robust error handling and more.

t3-env

envin is highly inspired by t3-env and shares the same philosophy of being framework-agnostic and providing a simple and easy to use API.

It enhances the experience of t3-env by solving most common issues reported by the community (e.g. about presets) and adding a CLI with a live preview on top of it.

envkit

Envkit is a framework-agnostic environment variable management toolkit that focuses on developer onboarding experience.

Its standout feature is providing a beautiful, customizable UI fallback when environment variables are missing, making it particularly valuable for teams where new developers need to quickly get up and running.
