9 platforms people move to from OpenRouter, what each is actually built for, and the honest reason each might be wrong for you. Every claim below is either something the vendor states in its own docs or a count taken from a public catalog endpoint on 2026-09-10. No competitor prices are quoted — rate cards move faster than pages do.
This page is published by OttoPort, which is one of the 9 listed. We have written our own entry to the same standard as the rest, including what it is bad at.
OpenRouter is a hosted multi-model API: one account and one key reach a catalog it maintains, with no provider contracts of your own. Its public model endpoint returned the following on 2026-09-10.

Worth stating plainly, because a lot of comparison content still gets it wrong: OpenRouter is not text-only. Veo 3.1, Kling 3.0, Seedance 2.0, and Sora 2 Pro were all in that catalog. If you are leaving, it is usually for one of three reasons — you want a model it does not carry, you already hold provider contracts and want only a control layer, or your workload is media generation rather than chat. The groups below map to those three.
One account and one key reach a catalog the platform maintains. Closest in shape to OpenRouter, and the group to look at first if that is the part you want to keep.
A large multi-modal catalog behind one OpenAI-shaped key.
A smaller, curated catalog with the creative models the big aggregators skip.
These do not resell model access. You keep your OpenAI, Anthropic, and Google contracts and put a control layer in front — routing, caching, limits, and logs. Pick one of these when the accounts are not the problem.
An open-source Python SDK and self-hosted proxy that normalizes providers to the OpenAI format.
An enterprise AI gateway bundled with observability, guardrails, governance, and prompt management.
A thin observe-and-control layer in front of the providers you already pay.
A gateway wired into the Vercel platform and the AI SDK.
Built to run image, video, and audio models — and to let you deploy your own. Reach for these when the workload is generation rather than chat, or when you need a model nobody's catalog carries.
A generative-media platform with a large endpoint catalog and serverless custom deploys.
A model host where thousands of community and proprietary models run, and where you can push your own.
Inference, fine-tuning, and GPU clusters for open-source models.
| Platform | Shape | Best for | Watch out |
|---|---|---|---|
| AI/ML API | Multi-model APIs, like OpenRouter | Breadth — the widest single catalog of the group, across chat, image, video, and speech. | Breadth means depth of documentation varies model to model. |
| OttoPort | Multi-model APIs, like OpenRouter | Teams who want Midjourney, Suno, or the full Wan lineup on the same key as GPT and Claude. | Far fewer LLMs than OpenRouter or AI/ML API — this is a curated catalog, not an exhaustive one. |
| LiteLLM | Gateways you point at your own provider accounts | Anyone who wants the routing layer inside their own infrastructure, with no vendor in the request path. | You run it, and you still need an account with every provider you call. |
| Portkey | Gateways you point at your own provider accounts | Organizations that need policy and audit around model access, not just a route to one. | The platform is the point — heavier than a team that only wants an endpoint will want. |
| Cloudflare AI Gateway | Gateways you point at your own provider accounts | Adding caching, rate limits, and logs to an existing integration with minimal change. | It gives you visibility and control, not a catalog — the provider accounts stay yours. |
| Vercel AI Gateway | Gateways you point at your own provider accounts | Teams already deploying on Vercel who want routing and spend visibility in the same place. | Most valuable inside the Vercel ecosystem; several modalities are still marked beta. |
| fal | Generative-media platforms and model hosts | High-volume image and video generation, and teams that want to run their own model on the same infrastructure. | Media-first — not the place to consolidate your LLM traffic. |
| Replicate | Generative-media platforms and model hosts | Open-source and long-tail models, fine-tunes, and anything you need to publish yourself. | Billing shape varies by model, which makes cost harder to predict than a flat rate card. |
| Together AI | Generative-media platforms and model hosts | Open-weight models at scale, and training or fine-tuning on your own data. | Centred on open-source models — closed frontier models are not the point. |
The questions people actually search alongside this one.
There is no single best one, because OpenRouter does three separable jobs: it maintains a catalog, it resells access so you need no provider accounts, and it routes and meters requests. If you want the catalog, look at AI/ML API or OttoPort. If you already hold provider contracts and only want routing, caching, and logs, look at LiteLLM, Portkey, Cloudflare AI Gateway, or Vercel AI Gateway. If the workload is image, video, or audio generation, look at fal, Replicate, or Together AI.
No. Its public model endpoint listed 435 models with text output, 54 with image output, 28 with video output, and 4 with audio output on 2026-09-10, including Veo 3.1, Kling 3.0, Seedance 2.0, and Sora 2 Pro. Any comparison that treats OpenRouter as text-only is out of date.
OpenRouter is a hosted service that resells model access: one account and one key, and no provider contracts of your own. LiteLLM is an open-source Python SDK and self-hosted proxy that normalizes providers to the OpenAI format but does not host models — every request goes out on your own provider keys, and you operate the proxy. Choose OpenRouter to avoid managing accounts, LiteLLM to keep the routing layer inside your own infrastructure.
Neither OpenRouter's nor AI/ML API's public catalog listed Midjourney or Suno on 2026-09-10. OttoPort carries Midjourney V7 and V8.1 and Suno v5 alongside GPT, Claude, Gemini, Veo, Kling, and Seedance on one OpenAI-compatible key. Model availability changes, so check the current catalog before committing.
It depends on the type. Multi-model APIs such as OpenRouter, AI/ML API, and OttoPort connect to providers on your behalf, so one account covers the catalog. Gateways such as LiteLLM, Cloudflare AI Gateway, and Vercel AI Gateway sit in front of accounts you hold yourself. Portkey is a gateway with an added unified-access layer, so read its docs for the case you have in mind.
One OpenAI-compatible key for 80 models across chat, image, video, speech, and music — including Midjourney and Suno, which the other catalogs on this page do not list. Prepaid credits, no subscription.
