UnoRouter
Gives individual users one OpenAI-compatible API key for GPT, Claude, Gemini, DeepSeek and other models, routed by default to the cheapest live provider group, with free models included; currently no business accounts.
UnoRouter is a hosted, open-source AI gateway: one OpenAI-compatible API key reaches models from OpenAI, Anthropic, Google, DeepSeek and other developers. Its endpoint is https://api.unorouter.com/v1, and by its own count in November 2026 it serves more than 200 models from about 50 providers. It is run as a sole proprietorship registered for VAT in Germany. Requests are served by third-party providers arranged in groups, each with its own price. By default a request goes to the cheapest live group and fails over to the next one on errors, and a key can be pinned to chosen groups instead. Models whose name ends in :free cost nothing, with a cap of about one request per minute per model; paid models are billed per use from prepaid credit that starts at $1, or from plans at $20, $50 and $100 a month. Two limits come from its own legal pages, dated October 20, 2026. The terms say UnoRouter currently does not offer accounts for business customers. The privacy policy says many requests, including those to models from well-known Western developers, are served by providers in China, Hong Kong, Singapore, Thailand and the United Arab Emirates, and by providers in the United States that are not certified under the EU-US Data Privacy Framework; it adds that some of these providers inspect, retain or train on what they receive, and tells users not to send other people's personal data.
What it does
UnoRouter sits between your code or AI client and the providers that serve AI models. You sign up, create an API key and point any OpenAI-compatible client at https://api.unorouter.com/v1; its docs show Claude Code connecting through ANTHROPIC_BASE_URL and Gemini CLI through GOOGLE_GEMINI_BASE_URL. Every model is served by one or more provider groups, each with its own price, and each model page lists them. With the default setting, auto, a request goes to the cheapest live group and moves to the next one when a provider fails. On a key you can instead pin a model to specific groups or set a price range, and a request can name a group with the X-Group header; the group that serves the request sets the rate billed. Each key has its own name, expiry date, spending limit, model allowlist and IP allowlist. Models whose name ends in :free are routed only to free providers and never use your balance, at about one request per minute per free model per user; the pricing page warns that they run on shared upstream free tiers and can be busy, slow or fail. Paid models have no limit set by UnoRouter, and failed requests are not billed. Credit is bought by card, Google Pay, Apple Pay, Alipay or cryptocurrency. According to its terms, offers from providers in countries without an adequate level of data protection under EU rules are marked in the model catalog with the provider's country, and for providers that use inputs for their own purposes such as training, or have not published how they handle them, UnoRouter shows a notice or asks for consent before the first request. The site also has a built-in chat client with character cards and lorebooks; it runs free models without an account and keeps conversations in the browser. The storefront and the gateway backend, which its README describes as a fork of new-api, are published at github.com/unorouter under the AGPL-3.0 licence. UnoRouter also publishes ai-model-verifier, a tool that checks whether an endpoint serves the model it claims, and says it runs these checks on every provider it routes to.
Who it is for
- Individual developers who want to use many models without opening an account with each AI developer
- People running coding agents such as Claude Code, Cline, Roo Code, Kilo Code, OpenCode, Aider or Codex
- Users of chat clients such as SillyTavern, RisuAI, Chub or Janitor AI that accept an OpenAI-compatible endpoint
- Hobbyists and students who want to try models for free before paying
Problems it solves
- Each AI developer needs its own account, API key and prepaid balance
- A rate limit or outage at one provider stops an app that depends on a single upstream
- Trying a new model usually means paying before you know whether it fits
- One shared key gives no way to cap spending or restrict models for each project
Best use cases
- Comparing answers from models by different developers with one key
- Running a coding agent or CLI on a low-cost or free model for a personal project
- Connecting SillyTavern, RisuAI or Janitor AI to free models
- Giving each side project its own key with a spending limit and a model allowlist
When to use
Use UnoRouter as a private individual when you want to reach many AI models through one key at low or no cost, for code, experiments and chat that contain no personal or confidential data, and you accept that requests are served by third-party providers chosen by price unless you pin them.
Do not choose UnoRouter for a company: its terms, dated October 20, 2026, say it currently does not offer accounts for business customers. Do not send prompts that contain other people's personal data, customer data or confidential material: its privacy policy says many requests are served by providers in China, Hong Kong, Singapore, Thailand, the United Arab Emirates and the United States, that some of them inspect, retain or train on what they receive, and that the cheapest group, which automatic routing picks, is often one of these providers. Do not rely on free models for anything that must stay available, since they are capped at about one request per minute and can be busy, slow or fail. It also does not fit sexually explicit or NSFW content, which its acceptable use policy bans, or users under 13; users under 18 need a parent's or guardian's consent.

Frequently asked questions
Is UnoRouter free?
Partly. Models whose name ends in :free cost nothing and never use your balance, and no credit card is needed to start. The cap is about one request per minute per free model per user, and the pricing page says free models run on shared upstream free tiers, so they can be busy, slow or fail.
How much do paid models cost?
Paid models are billed per use from prepaid credit, and each model page lists the input and output price of every provider group. You can add credit from $1. Three plans give twice their price in credit: Starter costs $20 a month for $40 of credit, Pro $50 for $100 and Scale $100 for $200. Plan credit is released in weekly parts of $10, $25 or $50, and the unused part does not carry over to the next week. Plans also cut UnoRouter's own waiting time on free models by 50% (Starter) or 75% (Pro), or remove it (Scale); the providers' own limits still apply. Failed requests are not billed.
Does credit expire?
The pricing page and the docs say purchased pay as you go credit never expires, while reward credit expires 12 months after you receive it. The terms of service, dated October 20, 2026, also say credits may expire after a period of inactivity as specified in your account settings or the current pricing terms, so check your account before leaving a balance unused.
Can a company use UnoRouter?
Not at present. Its terms of service, dated October 20, 2026, say UnoRouter currently does not offer accounts for business customers.
Where do my prompts go?
To the provider group that serves the request, which with automatic routing is the cheapest one available. The privacy policy says many requests, including those to models from well-known Western developers, are served by providers in China, Hong Kong, Singapore, Thailand and the United Arab Emirates, and by providers in the United States that are not certified under the EU-US Data Privacy Framework; that the cheapest group is often one of them; and that some of these providers inspect, retain or train on what they receive. Each model page lists the groups, and a key can be pinned to specific ones. UnoRouter says it does not use prompts or responses to train its own models; its policy tells users not to include other people's personal data and advises against including their own.
Which tools does it work with?
Any client that accepts an OpenAI-compatible base URL and API key. Its docs cover OpenCode, Cline, Roo Code, Kilo Code, Zed, Claude Code, Aider, Codex, Gemini CLI and OpenClaw, and the chat clients SillyTavern, Janitor AI, Chub and RisuAI.
Is UnoRouter open source?
The storefront and the gateway backend are published at github.com/unorouter under the AGPL-3.0 licence, and the tool that syncs models and prices from providers is published there under the MIT licence. This profile describes the hosted service at unorouter.com.
Can I get a refund?
The refund policy, dated June 17, 2026, allows a request within 7 days of the payment if you have used no more than 20% of the credit or quota you bought; approved refunds usually take 5 to 10 business days. The terms add that refund eligibility is decided at UnoRouter's discretion. Statutory consumer rights are not affected.
What content is not allowed?
The acceptable use policy, dated June 30, 2026, bans sexually explicit, pornographic or NSFW content of any kind in text, images and video, including through a connected third-party client. It also bans deepfakes and impersonating a real person without consent.
Who runs UnoRouter?
According to its legal notice, dated October 14, 2026, UnoRouter is run by Andrius Ziobakas as a sole proprietorship, with a German VAT ID and a postal address in Sankt Augustin, Germany. Support is available by email at [email protected] and on Discord.
More information
UnoRouter treats the route as part of the product: each model page shows which provider groups serve the model and at what price, and a key can follow the cheapest group or stay pinned to the ones you choose.
