UnoRouter is a unified API gateway that connects developers and AI enthusiasts to over 282 AI models through a single key. With support for 52+ providers and upstreams, it removes the friction of managing multiple API credentials, billing accounts, and integration formats. The platform serves both free and paid models, with 150 available at no cost and 132 offered on a pay-per-use basis.
What it offers
At its core, UnoRouter provides an OpenAI-compatible API endpoint that works across a wide range of clients and tools. This means you can point your existing applications, coding agents, or chat interfaces at UnoRouter and immediately gain access to models from Anthropic, OpenAI, Google, DeepSeek, Meta, Mistral, Alibaba Cloud, Moonshot AI, and many others. The catalog spans reasoning models, coding assistants, vision-language models, and specialized tools for translation, roleplay, and general conversation.
Who it is for
The platform is designed for several distinct audiences. Developers building AI-powered applications can use one key to experiment with different models without rewriting integration code. Coding agent users can connect tools like Cline, Roo Code, Kilo Code, Zed, and OpenCode through the same endpoint. Character and fiction enthusiasts can integrate with SillyTavern, Janitor.AI, Chub, and RisuAI. CLI users working with Aider, Codex, Gemini CLI, and similar terminal tools also have documented setup paths.
Core capabilities
- Unified access: A single API key unlocks the entire model catalog, eliminating the need to juggle multiple provider accounts.
- OpenAI compatibility: Standard OpenAI-format requests work out of the box, so existing SDKs and client libraries require minimal changes.
- Free tier: 150 models are available at no cost, making it practical to prototype, learn, and run lightweight workloads without spending.
- Broad client support: Integration guides cover coding agents, character chat clients, desktop chat apps, web UIs, and CLI tools.
- Live inference: The platform reports over 1.7 trillion tokens served and more than 34 million requests, with live throughput metrics displayed on the homepage.
Typical use cases
UnoRouter fits workflows where flexibility and cost control matter. A developer might use a free model for testing and switch to a paid frontier model for production. A writer might route creative prompts through a roleplay-optimized model while using a separate model for research summaries. A coding agent user can configure their tool once and change models by editing a single string rather than reconfiguring credentials.
The platform also includes an on-site chat interface, so users can try models directly in the browser before committing to an integration. This lowers the barrier for people who want to evaluate model quality without writing any code.
What makes it different
Rather than locking users into a single provider ecosystem, UnoRouter treats models as interchangeable resources behind one endpoint. The combination of a generous free tier, OpenAI compatibility, and documented integrations for both developer and consumer-facing tools makes it a practical choice for anyone who wants to experiment broadly without managing a patchwork of API keys.
