# OpenRouter vs LiteLLM vs Cloudflare AI Gateway: Marketplace, Proxy, or Edge — How to Route Your LLM Traffic in 2026

> One buys you a marketplace, one is a proxy you run, one wraps the providers you already use. Here's how a founder picks where to put the LLM control plane in 2026.

## Key takeaways

- Take OpenRouter to buy a marketplace, LiteLLM to run a proxy you own, and Cloudflare AI Gateway to wrap providers you already use with an edge layer.
- OpenRouter is a hosted marketplace: one key, hundreds of models, passthrough token rates plus a ~5.5% credit fee — you buy access.
- LiteLLM is an open-source proxy/SDK you self-host: virtual keys, budgets, and logs over your own provider accounts — you own the infra.
- Cloudflare AI Gateway is an edge gateway that observes and accelerates — caching, retries, rate limits, fallback, analytics — without reselling your tokens.
- They aren't rivals so much as layers: the common 2026 stack is edge in front, proxy in the middle, marketplace underneath — stacked, not chosen between.

## At a glance

| Dimension | OpenRouter | LiteLLM | Cloudflare AI Gateway |
| --- | --- | --- | --- |
| Where it runs | Their servers | Your server (or laptop) | Cloudflare's edge network |
| Billing model | Passthrough token rates + ~5.5% credit fee; BYOK fee after free tier | Software is free; you pay providers directly; enterprise tier optional | Core features free; BYOK pays the provider direct; optional Unified Billing ~5% fee |
| Token markup | None on tokens — you buy access through them | None — your own keys and contracts | None by default — it observes, it doesn't resell |
| Core value | One key for hundreds of models | Virtual keys, budgets, and logs over your own accounts | Caching, rate limits, retries, fallback, analytics at the edge |
| Reach for it when | You want one account and one bill, fast | You want governance you run and own | You want to wrap providers you already use |

## By the numbers

- **3** — routing approaches compared
- **5.5** — percent fee on OpenRouter credit purchases
- **100** — plus LLM providers LiteLLM fronts with your own keys
- **20** — plus providers Cloudflare AI Gateway sits in front of

> **The one-line pick:** Take **[OpenRouter](/stack/openrouter)** if you want one account and one bill for hundreds of models with zero ops. Take **[LiteLLM](/stack/litellm)** if you want budgets, virtual keys, and logs you run over the provider accounts you already own. Take **Cloudflare AI Gateway** if you want to wrap the providers you already call with caching, retries, and analytics at the edge — without handing anyone your billing.

Three tools keep landing on the same "LLM gateway" comparison page, and all three answer a different question. One sells you access. One gives you a control plane to run. One sits in front of what you already have and makes it faster and observable. Pick the wrong axis and you'll pay a marketplace fee for governance, or self-host a proxy when all you needed was a cache.
Why route at all
You rarely call one model for one thing forever. You want a cheap model for classification and a [frontier model](/topics/model-selection) for the hard turn. You want a fallback when a provider 5xxes mid-agent. You want to know what you spent, cap what a rogue loop can burn, and cache the prompt you send a thousand times an hour. That's routing — and where you put it decides who owns your keys, your bill, and your logs. (For the routing-logic layer itself, see [Build a cost-aware model router for your agent](/posts/build-cost-aware-model-router-for-your-agent.html).)
The distinction that matters isn't feature count. It's **buy a marketplace, run a proxy, or wrap with an edge gateway.**
OpenRouter — buy the marketplace
**OpenRouter** is a hosted aggregator. You point OpenAI-compatible requests at one endpoint and it fans out to hundreds of models across dozens of providers behind a single key and a single invoice. It does provider failover automatically, and it passes provider token pricing straight through — no per-token markup. The money comes from the edges: roughly a **5.5% fee on credit purchases** (a touch less on crypto), and a small per-request fee on bring-your-own-key traffic after a free monthly allowance.
The non-obvious part: you're not paying for tokens, you're paying to *never sign the contracts.* One relationship instead of seventy. The trade is that the control plane is theirs — your spend caps, key rotation, and activity log all live in their dashboard, on their terms. For a solo build or an early prototype, that's the feature. (It's also why the long tail of models lives here first — see [Chinese AI models on OpenRouter: token share vs revenue](/posts/chinese-ai-models-openrouter-token-share-vs-revenue.html).)
LiteLLM — run the proxy
**LiteLLM** is something you stand up. It's an open-source Python SDK and a self-hostable proxy that gives you one OpenAI-format interface to 100+ providers using *your* keys. It has a router with retries, fallbacks, and load balancing — but the reason teams deploy it is the control plane: **virtual keys** scoped per team or app, budgets and rate limits on those keys, caching, and logging piped to [Langfuse](/stack/langfuse), [LangSmith](/stack/langsmith), or OpenTelemetry.
The software is free; you pay for the compute you host it on and the tokens you consume, with a commercial enterprise tier for SSO and support. The insight here is ownership: LiteLLM doesn't get you access — you already have access. What it gives you is the sentence *"this team's key has a $200/month ceiling, that app overflows to a cheaper model, and every call lands in our logs,"* enforced over contracts that are yours. OpenRouter can't do that over your own Azure or Bedrock commit, because those contracts aren't with OpenRouter. For the crowded field of self-hosted gateways, see [Bifrost vs LiteLLM vs Portkey](/posts/bifrost-vs-litellm-vs-portkey-llm-gateway-2026.html).
Cloudflare AI Gateway — wrap with an edge
**Cloudflare AI Gateway** is the odd one out, and the one most people misfile. It doesn't aggregate a catalog and it doesn't resell tokens. It sits at Cloudflare's edge *in front of* the 20+ providers you already call — change your base URL, keep your provider key — and layers on **caching, rate limiting, request retries, model fallback, analytics on tokens and cost, request/error logging, and guardrails** (content moderation and DLP scanning). The core features are free; you pay only for extras like persistent logs beyond quota.
Crucially, with bring-your-own-keys you pay the provider **directly** — Cloudflare never touches your billing. There's a new **Unified Billing** option that pays third-party usage through your Cloudflare invoice for a ~5% fee, but it's opt-in; the default posture is observe-and-accelerate, not resell. (This is the "free LLM proxy" reputation — unpacked in [Cloudflare AI Gateway as a free LLM proxy](/posts/cloudflare-ai-gateway-free-llm-proxy.html).) One tell of its true role: OpenRouter is *listed as one of its supported providers.* It wraps marketplaces; it isn't one.
The decision, by team shape
These aren't rivals so much as layers — the common 2026 stack runs all three: Cloudflare at the edge, LiteLLM in the middle, OpenRouter as one upstream underneath. Pick by what's actually missing:
- **Solo founder shipping fast, no ops budget:** OpenRouter. One key, one bill, hundreds of models. The control plane is theirs, and that's the trade you want.
- **Team with existing provider contracts (Azure, Bedrock, direct Anthropic) that needs governance:** LiteLLM. Virtual keys, budgets, and logs over accounts you own. You run it; you own it.
- **You already call providers directly and just want speed, caching, and visibility:** Cloudflare AI Gateway. Change the base URL, keep your keys, get analytics and retries at the edge for free.
- **You want breadth *and* your own control plane:** LiteLLM out front, OpenRouter as one governed upstream — optionally with Cloudflare AI Gateway wrapping the whole thing for edge caching and logs.

The "vs" is a category error. This piece extends the two-way [OpenRouter vs LiteLLM](/posts/openrouter-vs-litellm.html) with the third axis most stacks are missing. The honest question was never which one wins — it's which layer you're short, and the answer is often more than one.

## FAQ

### Does Cloudflare AI Gateway resell tokens like OpenRouter?

No. By default you bring your own provider keys and pay the provider directly — Cloudflare sits in front to cache, retry, rate-limit, and log. It only touches billing if you opt into Unified Billing, which adds ~5% and is optional.

### Can I use these together?

Yes, and it's common. Cloudflare AI Gateway can sit in front of OpenRouter or your direct providers; LiteLLM can route to OpenRouter as one upstream. They stack: edge observability, self-hosted governance, and a marketplace underneath.

### Which is cheapest?

On raw tokens they're similar — none marks up per-token by default. The cost is elsewhere: OpenRouter's ~5.5% credit fee, LiteLLM's hosting and ops you run yourself, and Cloudflare's free core with paid logging extras.

### Do I have to self-host anything?

Only LiteLLM. OpenRouter and Cloudflare AI Gateway are both managed. LiteLLM is the one you deploy and own — that's the entire point of it.

### Which has the most models?

OpenRouter lists the most behind one key — hundreds across dozens of providers. LiteLLM reaches 100+ providers with your own keys. Cloudflare fronts 20+ providers but doesn't aggregate a catalog; it wraps whatever you already call.
