theloop vs everyone.

Most of these tools solve a neighbouring problem, not the same one. Each page takes two minutes, says plainly where the other tool wins, and links to its docs.

All comparisons

framework

vs LangChain

A kit you build into your app vs a service your app calls.

 graph framework

vs LangGraph

Saves every step vs remembers nothing at all.

 hosted API

vs OpenAI

One provider's cloud vs any provider, on your servers.

 TypeScript library

vs Vercel AI SDK

Same engine, but the loop moves out of your code.

 AI gateway

vs LiteLLM

Routes model calls vs runs the whole loop. They stack.

 workflow builder

vs n8n

Automations on a canvas vs an engine inside your product.

The one-line rule. Want the agent inside your code? Take a framework. Happy for it to live in a vendor's cloud? Take a provider's API. Want a stateless service your product calls, with any model and nothing stored? That's theloop.
