Use Cases

Switching an existing app between AI providers without rewriting code, by pointing an OpenAI-compatible client at one endpoint
Connecting coding agents such as Cline, Roo Code, Aider, or Codex to hundreds of models through a single API key
Running character roleplay and fiction chats in SillyTavern, Janitor.AI, or RisuAI using pay-per-token or free models

Who it is for

Developers building apps or agents who want one OpenAI-compatible API across many AI providers.
Users of AI coding agents and terminal CLI tools who want access to many models with one key.
Character roleplay and fiction chat users who import cards into SillyTavern, Janitor.AI, or similar clients.

Pricing

Pay-as-you-go with no subscription and no markup on provider rates: you pay what the upstream provider charges, per token. Top up any amount from $1, and credits never expire. A free tier gives access to free models, and optional monthly plans add bonus credit on top of what you pay.

Verdict

Worth it if you call more than one model provider, or expect to. The single OpenAI-compatible endpoint means switching models is a string change rather than an integration rewrite, and automatic failover keeps a provider outage from taking your app down with it. Being open source and self-hostable, there is no lock-in: you can run the same gateway on your own infrastructure. Less compelling if you are committed to exactly one provider and have no plans to compare alternatives.

FAQ

How does UnoRouter pricing work?

You pay per token consumed. Each model has its own input, output and cache rate, billed from your account credit. There is no monthly subscription required for Pay As You Go.

Do I need a subscription?

No. Pay As You Go is fully self-serve, top up once and consume any model. Subscriptions give better value (up to 1.75x credit multiplier) if your usage is predictable.

Is the API compatible with OpenAI?

Yes. UnoRouter exposes an OpenAI-compatible endpoint for chat completions, plus Anthropic and Gemini compatible endpoints. Point any OpenAI SDK at our base URL and use your UnoRouter API key.

Which models are included?

Every plan includes access to all supported models (Claude, GPT, Gemini, DeepSeek and more). We do not gate models by tier.

What happens if a provider fails?

UnoRouter routes requests across multiple providers with automatic failover. If one provider is rate-limited or down, we retry against the next healthy upstream transparently.

Can I get a refund?

Unused prepaid credit is refundable for 30 days from purchase. Contact [email protected] for refund requests.

Can I use this with SillyTavern, RisuAI, or other OpenAI-compatible AI chat clients?

Yes. Every plan works as a custom OpenAI-compatible source in any major character chat client. SillyTavern, Janitor.AI, RisuAI, and Chub each have a setup guide in the docs.

How long can my conversations or character history be?

UnoRouter supports the full context window of every model, up to 1M tokens on Gemini and 200k on Claude. Long character conversations and long codebases both work.
