Direct alternatives to OpenRouter
If you came here from "openrouter alternatives", you probably want what OpenRouter does: a single API that routes across many LLM providers, with fallback, cost comparison, and one bill. Direct provider APIs (OpenAI, Anthropic, Together) are not alternatives, they are what OpenRouter routes to. The closest direct replacements:
- LiteLLM: the canonical open-source alternative. Python SDK and proxy server supporting 100+ LLM providers with one OpenAI-compatible interface. Self-hostable, MIT-licensed, with optional commercial features for SSO and advanced auth.
- Portkey: AI gateway with routing, caching, retries, and built-in guardrails. Combines provider routing with observability and prompt management in one product.
- Vercel AI Gateway: routing layer for hundreds of models, tightly integrated with the Vercel AI SDK but usable independently. Good fit if the stack is already on Vercel.
- Cloudflare AI Gateway: edge-deployed routing layer with caching, rate limiting, and analytics. Useful if you are already on Cloudflare and want a router that runs close to your edge.
- Helicone: less router-focused than the others, but acts as a proxy with logging, caching, and rate limiting across providers. Common pick when observability matters as much as routing.
The full list below also includes direct provider APIs (Together, Fireworks, DeepInfra), specialized inference hardware (Groq, Cerebras), and GPU clouds that share OpenRouter's categories but solve different problems. Useful if you are deciding whether to stay on a gateway or go direct.
