Compare

OpenRouter alternatives, compared honestly.

Aggregators, gateways and first-party inference providers, side by side on the things that actually differ: fees and markup, OpenAI-compatibility, and free tiers. Independent, no affiliate links.

Aggregators

One key and one wallet routed across many models from many upstream providers — the OpenRouter model. You compare on breadth, routing and fees.

Gateways

An ops layer in front of your own provider keys (BYOK): observability, caching, guardrails and routing. You keep direct provider billing and pay for the control plane.

Inference providers

First-party hosts that run open models on their own hardware at their own prices. You compare on speed and cost for open-weight models, not on breadth.

Frequently asked

What is the best alternative to OpenRouter?

It depends on what you're optimizing for. For zero markup, look at Vercel AI Gateway or Hugging Face Inference. For raw speed on open models, Groq. For the cheapest open-model hosting, DeepInfra or Novita. For self-hosting and governance over your own keys, LiteLLM or Portkey. OpenRouter itself is still the broadest single-wallet aggregator.

Why use an OpenRouter alternative at all?

Common reasons: avoiding OpenRouter's credit top-up fee (5.5% on cards), getting faster inference, self-hosting the routing layer for privacy or control, keeping direct billing with your own provider keys, or needing capabilities OpenRouter doesn't route to, like per-second image and video models.

What's the difference between an aggregator, a gateway and an inference provider?

An aggregator gives you one key and one wallet across many models from many providers, the OpenRouter model. A gateway sits in front of your own provider keys and adds observability, caching and routing, so you keep direct billing. An inference provider hosts open models on its own hardware at its own prices and competes on speed and cost rather than breadth.

Are these providers OpenAI-compatible?

Most expose an OpenAI-compatible /v1 endpoint, so switching is often just a base URL and API key change. A few are partial (Hugging Face and Eden AI cover chat but route other tasks through their own SDKs) and Replicate uses its own predictions API rather than a drop-in chat endpoint.
