4 OpenRouter alternatives, compared

  1. 1.MuiRouter

    Start free

    A managed, OpenAI-compatible gateway to OpenAI, Claude, Gemini, Grok, Workers AI, Moonshot and MiMo. Native Anthropic and OpenAI endpoints, per-token pricing with no separate top-up fee, and a built-in MCP server.

    • No infrastructure to run — sign up and call the API
    • Native /v1/messages and /v1/responses endpoints, not just a translation layer
    • One wallet, one usage log across every model
    • Narrower model catalog than some alternatives (curated, not 100+)

    Best for developers who want a managed endpoint with native Claude/GPT access and simple per-token billing.

  2. 2.LiteLLM

    Open source

    An open-source proxy and Python SDK you self-host, translating 100+ providers into one OpenAI-shaped interface. Enterprise adds SSO, audit logs and support.

    • 100+ providers — the widest catalog here
    • Full control over deployment and routing logic
    • Free open-source core
    • You run and maintain the infrastructure yourself
    • Enterprise features require a paid, custom-priced tier

    Best for teams that want full infrastructure control and are comfortable self-hosting.

  3. 3.Portkey

    Enterprise stack

    A production stack for AI teams bundling an AI gateway, observability, guardrails, governance and prompt management, with access to 1,600+ LLMs.

    • Broadest model access — 1,600+ LLMs
    • Deep observability, guardrails and governance features
    • Free tier to get started
    • Paid plans needed for full production features
    • More platform than a lightweight router — heavier setup

    Best for larger teams that need governance, guardrails and observability alongside routing.

  4. 4.Cloudflare AI Gateway

    Built into Cloudflare

    An observability and control layer for AI calls to Workers AI, Anthropic, Gemini, OpenAI and more, with caching, rate limiting and automatic fallback — available on any Cloudflare account.

    • No extra account needed if you're already on Cloudflare
    • Built-in caching, rate limiting and fallback
    • Available on every Cloudflare plan
    • Best suited to teams already building on Cloudflare
    • Less focused on unified per-token billing across providers

    Best for teams already running on Cloudflare who want caching and fallback without a new vendor.
