UnoRouter
UnoRouter is a unified AI API platform that gives developers one OpenAI-compatible key for 253+ models across 49+ upstream providers, including 132 free models and 121 pay-per-use routes. Add credit or subscribe for extra credit, then point coding agents, chat clients or its built-in browser chat at a single endpoint. Free models need no account, and pay-as-you-go credit never expires.
What is UnoRouter?
UnoRouter is a unified AI API gateway and model router that gives developers one OpenAI-compatible key for 253+ models drawn from 49+ upstream providers. Instead of holding separate accounts and balances with Anthropic, OpenAI, Google, DeepSeek, Mistral, MiniMax, NVIDIA and dozens more labs, a user signs up once, receives a single endpoint at api.unorouter.com/v1, and switches models by changing the model ID. The catalogue is split into 132 free models, marked no cost, and 121 paid models billed per use.
The platform is positioned as more than plumbing. The homepage calls it an API and a chat client: the same key that powers your code also powers a built-in browser chat with characters, personas, lorebooks, presets, prompt templates, group chat, swipes and SillyTavern card import. Free models are wired in on the backend, so anyone can open the chat and start talking with no account, no key and no setup, and conversations stay in the browser rather than on the server. Bring-your-own-key is supported too, letting users point the chat at any OpenAI-compatible endpoint.
For builders, the site emphasises a fully OpenAI-compatible surface with automatic provider failover and multi-protocol support, so an existing SDK or client keeps working after a base URL and key swap. Integration guides cover coding agents such as OpenCode, Cline, Roo Code, Kilo Code and Zed; CLI tools including Aider, Codex, Gemini CLI and OpenClaw; character and fiction clients such as SillyTavern, Janitor.AI, Chub and RisuAI; and chat clients like LibreChat, Open WebUI, LobeChat, Cherry Studio, Chatbox, AnythingLLM, TypingMind, BoltAI, Big-AGI and Page Assist.
UnoRouter also ships its own discovery surfaces. A models catalogue lists every routable model, a rankings page orders models by measured performance, and an Inspector tool tests AI API models directly in the browser, while a public status page tracks uptime. Traffic counters on the homepage, showing over 539 billion tokens served and more than 16 million requests, are presented as live proof of scale alongside a live tokens-per-minute figure.
Payment works on two rails. Pay-as-you-go credit can be topped up from $1 up to $10,000 by card, Google Pay, Apple Pay, Alipay, PayPal or crypto, and it never expires. Users with predictable spend can subscribe instead: Starter is $20 per month for $40 of API credit, Pro is $50 for $100, and Scale is $100 for $200, each delivered weekly. Free models stay available on every tier, and the subscriptions mainly reduce waiting on those free routes.

a models catalogue, a rankings board and an Inspector page test and compare models before production use.
Who is UnoRouter for?
UnoRouter suits developers who are tired of juggling several model vendors. The typical buyer already writes against an OpenAI-compatible client, so pointing a base URL and key at the gateway is a far smaller job than opening billing accounts with each lab, and swapping a model ID replaces a rewrite when a cheaper or stronger model appears. Solo builders and indie hackers are the second group. The catalogue marks 132 models as free, signup needs no credit card, and credit top-ups start at $1, which makes it a low-risk way to test whether a frontier model is good enough before committing real spend. Users of coding agents and CLI tools are the third. Documented guides cover OpenCode, Cline, Roo Code, Kilo Code, Zed, Aider, Codex, Gemini CLI and OpenClaw, so anyone already running an agent can route all of its traffic through one key and one usage view. Character-chat and fiction writers are the fourth, and this is the audience the built-in chat is clearly built for: personas, lorebooks, presets, SillyTavern card import, group chat and swipes, all reaching the same models the API serves. Privacy-conscious tinkerers form the fifth group, because the chat keeps conversations in the browser, free models need no account at all, and a personal OpenAI-compatible endpoint and key can be used instead of the hosted routes. Finally, small product teams with steady usage fit the subscriptions: $20, $50 and $100 tiers return double that value in API credit and pool many providers into one invoice and one dashboard rather than a dozen. Anyone wanting an annual contract or an enterprise agreement will not find one here yet, so those buyers should look elsewhere or negotiate through Discord.
UnoRouter Use Cases
Point an OpenAI SDK at one endpoint and switch between Claude, GPT, Gemini and DeepSeek by editing the model ID.
Run OpenCode, Cline, Roo Code or Zed against a single key instead of maintaining separate provider accounts.
Prototype for free against the 132 no-cost models before adding any pay-as-you-go credit to the account.
Host long character roleplay sessions in the built-in chat with lorebooks, personas and group conversations.
Import a SillyTavern card and continue the same characters through the on-site chat engine without a key.
Top up once and let pay-as-you-go credit cover mixed model traffic without any recurring monthly commitment.
Subscribe when monthly usage is predictable and take double the credit you pay for, delivered weekly.
Compare candidates on the rankings and Inspector pages before committing production traffic to one model.
