mission

// Why do developers leave the terminal to test an API?

// Why is the best interface for infrastructure a web dashboard?

// We believe the terminal is the ultimate developer environment.

termdx is an open source organization dedicated to building terminal-native tools that are fast, keyboard-driven, and respect the Unix philosophy. No electron wrappers. No context switching. Just sharp tools for sharp developers.
