Description

3code is a free and open source command-line coding agent built from the ground up to be efficient enough to use 3rd party token providers without a coding plan. It has a tight, no-frills user interface design and instant startup time, works on osx/windows/linux/termux and probably supports the provider you're using — including EU providers such as Mistral and TensorX for sensitive work on up-to-date models.
