KeepRouter vs OpenRouter
Looking for an OpenRouter alternative? KeepRouter and OpenRouter are both multi-model LLM API gateways — one API key for models from many makers. Both expose an OpenAI-compatible endpoint. Here is how KeepRouter differs, factually:
What's different about KeepRouter
- Two protocols, not one: KeepRouter speaks both the OpenAI API (/v1/chat/completions) and the Anthropic API (/v1/messages — the endpoint Claude Code and the Anthropic SDK use), so Claude-native tools work unchanged.
- Sold at cost — 0% token markup: every model's price is its underlying cost, with no monthly fee; prepaid, pay-as-you-go credits in USD.
- Maker-transparent, routing-private: every model page names the model's maker (OpenAI, Anthropic, Zhipu AI, ByteDance…), while the upstream routing is kept private.
- Bilingual: the whole site and docs are available in English and 简体中文.
- Prepaid, Merchant-of-Record billing: new accounts get free trial credit; card top-ups are processed by Paddle as Merchant of Record.
What is OpenRouter?
OpenRouter is a popular, well-established multi-model API aggregator that routes one API key to a large catalog of models through an OpenAI-compatible API. The points above are simply where KeepRouter takes a different approach.
