Envio

Envio is a command-line tool designed for managing environment variables securely. Developers use it to handle environment configuration through a terminal interface, making it useful for managing different settings across development, testing, and production environments. The tool is written in Rust and was developed by humblepenguinn. It is distributed under the Apache 2.0 license, which allows developers to freely use, modify, and distribute the software while providing protections for the original developer. The Apache 2.0 license includes explicit grants of patent rights and requires that modifications be documented.

As a terminal-based utility, Envio integrates into command-line workflows where developers need to set, view, or update environment variables. The Rust implementation provides performance benefits and memory safety guarantees. The tool's focus on security in environment variable management addresses concerns developers have about handling sensitive configuration data, such as API keys and database credentials, within their development processes.
