Looking for an OpenRouter alternative? How AnyRouter compares

Once you've decided to route through a gateway instead of wiring each provider by hand, the gateways start to differ on the things that show up on your invoice and in your codebase: whether there's markup on credits, whether you can route on your own provider keys, how billing and logs are presented, and how hard it is to leave.

• Markup — does the gateway add a fee on top of provider pricing?
• Bring your own keys — can you route on keys you already pay for, and at what cost?
• Billing & logs — one balance and one audit trail, or several?
• Lock-in — is the API a standard you can point elsewhere, or proprietary?

The column is intentionally just AnyRouter's facts: the point of an alternative is what you get, not a takedown of where you're coming from.

Because AnyRouter speaks the OpenAI API, switching is usually just the base URL and the key. Model ids become `provider/model`, and everything else — streaming, tools, the SDK — stays the same.

from openai import OpenAI

client = OpenAI(base_url="https://anyrouter.dev/v1", api_key="sk-ar-v1-...")

resp = client.chat.completions.create(
    model="anthropic/claude-opus-4-8",   # or openai/gpt-5.5, google/gemini-2.5-pro, ...
    messages=[{"role": "user", "content": "Hello"}],
