Comparison

Conifer and OpenRouter compared

Both give one API key for AI models from many providers. This page sets out how each one works, using each company’s own published documentation.

Summary

OpenRouter offers a larger catalog, in-region routing on its Business plan and contract terms such as SSO and SLAs on its Enterprise plan. Conifer serves a named model only as named, reports the exact cost of every request, refuses a request over a cost ceiling before any provider is called, and charges no fee on requests served by your own provider key.

OpenRouter details were read from openrouter.ai on 4 November 2026. Plans and prices change; check the linked pages before you decide.

Side by side

Which one fits

OpenRouter may suit you if
You want the largest catalog in one place, routing kept within the EU or the US, or SSO and a contractual SLA from the start.
Conifer may suit you if
You need each response to state the model that served and its exact cost, you want requests refused before they exceed a cost ceiling, you want automatic model choice limited to models you approve, or you want to put your own Azure OpenAI resource behind the same key with no added fee.

Moving from OpenRouter to Conifer

Address and key
Point your client at Conifer and use a Conifer key. With the OpenRouter provider for the AI SDK, pass the Conifer address when you create it.
const openrouter = createOpenRouter({
  baseURL: "https://api.conifer.build/v1",
  apiKey: process.env.CONIFER_API_KEY,
});
Model names
Names written the OpenRouter way, with the lab in front, keep working. anthropic/claude-opus-5 is served as claude-opus-5.
Other fields
Fields and headers that only OpenRouter uses are accepted and ignored, so an unchanged request is served.
Fallbacks
Move your fallback list into a request header, up to three models.
Check first
The moderations endpoint is not served. Check each model’s capabilities on the models page before sending tools or images.

Replace your provider key has the full steps.

Questions

Is Conifer an alternative to OpenRouter?
Yes. Both give one API key for models from many providers on an OpenAI-compatible interface. They differ in catalog size, fees, how a named model is handled, how cost is reported and which enterprise terms are offered, as the table on this page sets out.
Can I keep my OpenRouter model ids?
Yes. Conifer accepts model names written the OpenRouter way, such as anthropic/claude-opus-5, and serves them as the matching Conifer model. A model Conifer does not carry is refused rather than replaced.
Do I need to change my code to move from OpenRouter?
Usually not. Change the base URL and use a Conifer key. Fields and headers that only OpenRouter uses are accepted and ignored, so an unchanged request is served.
How do fallbacks move across?
List up to three fallback models in a request header. They are tried in order if the model you named cannot be served, and the response names the model that answered.
