OpenRouter Alternatives

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:

• NanoGPT: aggregator across a comparable catalogue (634 text models listed as of August 2026), plus image, video and audio. Bills text at each provider's list price rather than adding a percentage, and works without an account, with balances topped up in crypto or by card.
• 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.
• Requesty: hosted router in the same shape as OpenRouter: one OpenAI-compatible API across 400+ models from 30+ providers, with routing by cost, latency, or availability and automatic failover.
• 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.
• Vynaris: routes each request to a smaller model where one will do and returns a per-request cost receipt. Relevant if the reason you are shopping around is spend rather than coverage.
• EUrouter, Opper, Cortecs AI and Eden AI: hosted routers with EU data residency (EUrouter routes 100+ models and keeps processing in the EU; Opper serves 300+ models from AWS Stockholm; Cortecs routes across EU providers; Eden AI has a separate EU endpoint that refuses non-EU models). Relevant if the reason you are leaving OpenRouter is where requests get processed.
