I’m still new to this ecosystem but is this something you’d use together with langchain or does it replace some use cases there?

What’s missing right now are our guides showing how well ArchGW integrates with existing frameworks and tools. But the core idea is simple: it offloads low-level responsibilities—like routing, safety, and observability—that frameworks like LangChain currently try to handle inside the app. That means less bloat and more clarity in your agent logic.

And importantly, some things just can’t be done well in a framework. For example, enforcing global rate limits across LLMs isn’t realistic when each agent instance holds its own local state. That kind of cross-cutting concern needs to live in infrastructure—not in application code.

ArchGW complements langchain rather than replacing it - langchain handles agent orchestration/reasoning while ArchGW provides the infrastructure layer for prompt processing, guardrails and routing across your entire system.
