UnoRouter

UnoRouter - Unified AI API Gateway for Every Model

One key. 343+ models. 50+ providers. Zero lock-in.

UnoRouter is a unified AI API gateway that aggregates models from major providers (OpenAI, Anthropic, Google, DeepSeek, Zhipu, Meta, Mistral, and 40+ more) into a single OpenAI-compatible endpoint. Developers, AI engineers, and creators use one API key to access every model — whether building apps, running agents, or chatting with characters.

Key Features

• Universal Compatibility — Drop-in replacement for OpenAI, Anthropic, and Gemini APIs. Point any SDK at [https://api.unorouter.com/v1](https://api.unorouter.com/v1) and it works.
• Smart Routing & Failover — Requests automatically route to the cheapest healthy upstream. If one provider hits rate limits or goes down, UnoRouter retries transparently.
• Massive Model Catalog — 343+ models (248 free, 95 paid) covering text, vision, audio, embedding, and image generation. Includes Claude Opus/Sonnet/Haiku, GPT-4o/5, Gemini 3.x, DeepSeek V3/R1, GLM-5, Qwen, Llama, Nemotron, and more.
• Built-in Chat Client — Full-featured roleplay chat with characters, lorebooks, personas, presets, group chat, image generation, long-term memory, and SillyTavern card import — all running locally in your browser.
• BYOK & Privacy — Bring your own OpenAI-compatible endpoint and key; conversations never leave your browser.
• Flexible Billing — Pay-as-you-go (credits never expire) or subscribe for 1.5–1.75× credit multipliers. No model gating by tier.
• Integrations Galore — One-click setup for Claude Code, Codex CLI, Gemini CLI, OpenClaw, Aider, Continue.dev, Zed, Cline, Roo Code, SillyTavern, Janitor.AI, RisuAI, Chub, LibreChat, Open WebUI, LobeChat, AnythingLLM, and 20+ more.

Who It's For

• Developers building AI apps who want multi-provider resilience without managing multiple SDKs.
• AI Engineers running agents (Claude Code, Codex, OpenClaw) needing reliable, cost-effective model access.
• Creators & Roleplayers using SillyTavern, RisuAI, or the built-in chat for character-driven storytelling with free models.
• Teams wanting centralized billing, usage analytics, and API key management across projects.
