# Langcli

A terminal AI coding assistant compatible with Claude Code's configuration and skills, built to switch between multiple LLM providers within one session through its own router integration.

Langcli is an interactive coding assistant for the terminal that aims for full compatibility with Claude Code: existing configuration and skills work without changes, and the command-line usage matches Claude Code's own.

Its main addition is an integration called LangRouter, which lets a session switch between mainstream LLM providers and models mid-conversation without losing context, rather than committing to one model for the whole session. It installs through a shell or batch script, or from npm, or can be built from source with Bun.

The project describes itself as being built for educational and research purposes, developed as a secondary project based on an existing coding-agent codebase, and states that rights to Claude Code itself belong to Anthropic.
