Free and open-source alternatives to OpenRouter

OpenRouter alternatives in detail

  1. Portkey

    freemiumMITWebPlatform

    Portkey is an AI gateway and LLMOps platform: route to 1,600+ LLMs through one OpenAI-compatible API with simple and semantic caching, automatic retries, fallbacks, and load balancing — plus observability (logs, traces, cost and latency), prompt management, guardrails, virtual keys, and budgets. The fast routing gateway is open source (MIT) and self-hostable; the hosted control plane is freemium.

  2. LiteLLM

    open sourceMITSDK

    LiteLLM lets you call 100+ LLMs (OpenAI, Anthropic, Google, Bedrock, local, and more) through one OpenAI-compatible interface. Use it as a Python library, or run its proxy as a self-hosted gateway with central keys, fallbacks, retries, caching, cost tracking, and rate limits.

  3. Fireworks AI

    freemiumPlatform

    Fireworks AI is a production inference platform for open models. It serves 100+ models (text, vision, audio, image, embeddings) over an OpenAI-compatible API — as pay-per-token serverless or dedicated GPU deployments — and adds fine-tuning. Its proprietary serving stack targets low latency and high throughput for open-source architectures.

  4. Groq

    freemiumPlatform

    Groq is a hosted inference service that serves open-weight models — OpenAI GPT-OSS, Whisper, enterprise-only Llama, and Qwen in preview — on its custom LPU chips for unusually high tokens-per-second and low latency. The GroqCloud API is OpenAI-compatible, so most SDKs work by changing the base URL, and pricing is per-token with a free tier.

  5. Together AI

    paidPlatform

    Together AI is a hosted cloud for open-source models: serverless inference across a broad catalog (Llama, DeepSeek, Qwen, and more) behind an OpenAI-compatible API, plus fine-tuning and dedicated GPU endpoints and clusters. It's the managed way to run open-weight models without operating your own inference stack.
