New to LLMs?
Start with these plain-English guides before diving into the ranked shortlists.
Routing layer
Pre-filtered router and gateway views for teams that want a routing layer before, or instead of, a single model pick.
Best LLM gateways
LLM gateways sit between your app and one or more model providers. Use this list when you want a unified endpoint, provider failover, observability, or governance without changing the model decision itself.
Best LLM routers
LLM routers choose the model or tier for each request. Use this page when cost, quality, latency, or reliability depends on routing policy rather than one static model pick.
OpenRouter alternatives
OpenRouter is the flagship hybrid router in this seed, but it is not the only way to unify model access. This view excludes OpenRouter and keeps the alternatives that still give you gateway or hybrid routing behavior.
Self-hosted LLM routers
Self-hosted router and gateway options keep routing policy closer to your infrastructure. Use this list when vendor lock-in, data boundaries, or deployment control matter more than hosted convenience.
Open-source LLM routers
Open-source router and gateway projects are the right first stop when you need inspectable routing policy, self-host paths, or a proxy you can adapt. This page keeps open-source rows in one view across gateway, router, and hybrid types.
Cheapest LLM gateway options
Cost-focused routing can lower spend by sending simple requests to cheaper models or cheaper provider routes. Use this page for gateways and routers whose verified objective includes cost optimization.
LLM cost optimization routers
Cost optimization routers decide when a cheaper model or provider route is good enough. Use this list when you already know the task shape and need a routing layer to keep quality while reducing token spend.
