dotenvx
A secure dotenv–from the creator of `dotenv`
...It offers CLI commands that can encrypt and decrypt .env files, inject environment variables at runtime, and support conventions like layered environment file loading similar to Next.js or dotenv-flow. Beyond basic runtime usage, dotenvx includes tooling for key management, listing .env files in structured views, and operations like variable rotation and scoped overrides, bringing more robust secrets handling to modern app stacks.
