`Arch <https://github.com/katanemo/arch>`_ is an intelligent (edge and LLM) proxy, exclusively designed for prompts and agents - and built by the contributors of the widely adopted and loved `Envoy <https://www.envoyproxy.io/>`_ ).

**Move faster** by letting Arch handle the **pesky heavy lifting** in building agents: fast input clarification, agent routing, seamless integration of prompts with tools for common tasks, and unified access and observability of LLMs - all outside business logic.
