faq:
  - question: "What is a unified AI API gateway?"
    answer: "A unified AI API gateway is a single endpoint that routes requests to many model providers behind one API key and one billing relationship. Most speak the OpenAI API format, so switching to one means changing a base URL rather than rewriting your code. Examples include haimaker.ai, OpenRouter, LiteLLM, and Portkey."
  - question: "Is there a cheaper alternative to OpenRouter?"
    answer: "OpenRouter does not mark up per-token model rates, so the savings from switching come from platform fees rather than token prices. OpenRouter charges 5.5% on credit purchases with a $0.80 minimum, plus 5% on bring-your-own-key requests above 1M per month. A gateway without those fees keeps that percentage in your token budget."
  - question: "Do unified AI APIs add latency?"
    answer: "A little. A well-built gateway adds single-digit to low-double-digit milliseconds per call, and Bifrost measures its own overhead at 11 microseconds under a sustained 5,000 requests-per-second benchmark. That is invisible in a chat app but it compounds in agent loops, where one task can make dozens of sequential calls."

The best OpenRouter alternatives are haimaker.ai for coding-agent traffic and fee-free access to 200+ models, [LiteLLM](https://github.com/BerriAI/litellm) if the gateway has to run inside your own infrastructure, Portkey if a compliance team is asking the questions, and Together AI or Fireworks if you want one provider serving one model consistently. Which is right depends on why you are leaving, and there are only three common reasons: the platform fees, the opaque provider routing, or the missing SLA.

This is an honest map of the category, including the cases where OpenRouter is still the correct answer.

## What are the best OpenRouter alternatives?

Eight products compete for OpenRouter's users, and they are not interchangeable. Four are unified gateways with their own catalog (haimaker.ai, LiteLLM, Portkey, Requesty), two are direct inference providers that host models themselves (Together AI, Fireworks), one is an observability layer for keys you already own (Cloudflare AI Gateway), and one is a performance-first self-hosted proxy (Bifrost).

| | Catalog | Platform fee on top-ups | Provider control | Self-host | Agent setup |
|---|---|---|---|---|---|
| **haimaker** | 200+ models, 29 providers | None | Auto-routing or pinned | Hosted | `npx @haimaker/connect` |
| **OpenRouter** | Largest in category | 5.5% on credits ($0.80 min) | Automatic, opaque by default | Hosted | Manual config |
| **LiteLLM** | 100+ providers | None (you host it) | Full | Yes | Manual config |
| **Portkey** | Broad | Plan-based | Full | Yes | Manual config |
| **Requesty** | Broad | Plan-based | Latency-routed | Hosted | Manual config |
| **Together / Fireworks** | Their own hosted models | None | Single provider | No | Manual config |
| **Cloudflare AI Gateway** | None (bring your own keys) | None | Not applicable | No | Not applicable |
| **Bifrost** | 23+ providers | None (you host it) | Full | Yes | Manual config |

The table answers "what are my options." It does not answer "which one," because that depends on which OpenRouter problem sent you looking. Start there.

## Why do developers leave OpenRouter?

Three reasons, in rough order of how often they come up: platform fees that take a percentage before any tokens are bought, provider routing that quietly changes which host (and which quantization) serves a request, and the absence of a published uptime SLA. Most "OpenRouter is expensive" posts never say which one they mean.

#### The fees are structural, not a markup

OpenRouter's claim that it does not mark up inference is true. Per-token catalog rates match what the underlying providers publish. The cost lands somewhere else. Per [OpenRouter's own FAQ](https://openrouter.ai/docs/faq), buying credits by card costs 5.5% with a $0.80 minimum, and bring-your-own-key requests are free for the first 1M per month, then cost 5% of what that model and provider would normally cost on OpenRouter.

That combination is why the complaint is so consistent. On a $1,000 monthly spend, 5.5% is $55 that buys no tokens. Small top-ups fare worse: the $0.80 minimum on a $10 purchase is an effective 8% fee.

#### Provider routing is a black box

OpenRouter serves most open-weight models through a pool of upstream providers and picks one per request based on price and capacity. That is a real feature, and it is how you get availability when a provider falls over.

It is also why a model can feel inconsistent. Three consecutive calls to the same model name can land on three different hosts, and those hosts do not always serve the same quantization. Output quality moves and nothing in your code changed. For a chatbot, that is a shrug. For an agent running a long tool-use loop, a silently degraded model is a failed task and an hour of debugging.

#### There is no SLA

OpenRouter publishes no contractual uptime guarantee, and support runs largely through community channels. That is a reasonable trade for a prototype or a side project. It is a harder sell once something you bill customers for depends on it.

## What is each OpenRouter alternative actually good at?

Each of the eight wins in one specific situation and loses in the others, so read these as "pick this if your problem is X" rather than as a ranking. The unified gateways come first, then the direct providers, then the two specialists that rank for these searches while solving a narrower problem.

#### haimaker.ai — one key, 200+ models, built for coding agents

[haimaker.ai](https://haimaker.ai) is a unified, OpenAI-compatible gateway reaching 200+ models across 29 providers through a single endpoint and one key. Change your `base_url`, keep your existing OpenAI SDK code, and you are done.

Two things separate it from the rest of this list. Auto-routing sends each request to the model that fits it on cost, intelligence, or speed, instead of making you hard-code a model per call. And one command wires up a coding agent:

```bash
npx -y @haimaker/connect
```

That covers Claude Code, Codex, opencode, OpenClaw, Hermes, Cline, and Kilo Code, writing the provider config for you instead of making you hand-edit JSON.

**Pick it if:** you want breadth without a platform fee on top-ups, you drive coding agents, or you want routing to cut the bill rather than just proxy your requests. See [/model-api](/model-api) for integration details or [/connect](/connect) for the agent path.

#### OpenRouter — still the right answer sometimes

Credit where it is due. [OpenRouter](https://openrouter.ai) has the largest catalog in the category, a real community, a good model explorer, and a free tier that has introduced more people to more models than anything else here. Its provider fallback is a legitimate availability feature.

**Pick it if:** you are prototyping, you want the widest catalog including long-tail and experimental models, or you want the free tier to kick the tires on something new.

#### LiteLLM — the self-hosted default

[LiteLLM](https://github.com/BerriAI/litellm) is the open-source proxy most teams reach for when the gateway has to live inside their own infrastructure. It is a Python SDK plus a proxy server, speaks OpenAI format to 100+ providers, and handles cost tracking, load balancing, and logging. At 53,000+ GitHub stars it is the most widely deployed thing in this category.

The trade is honest: you run it. You own the upgrades, the failure modes, and the 2am page.

**Pick it if:** the request path must stay in your own VPC, you have platform engineers to keep it fed, or your compliance story requires that no third party sits in the middle.

#### Portkey — governance and guardrails

[Portkey](https://portkey.ai) is an AI gateway with observability, prompt management, PII redaction, and guardrails layered on top, and it ships an open-source gateway you can self-host. It is the usual pick when a compliance team, rather than an engineer, is driving the decision.

**Pick it if:** you need request-level governance, guardrails, or an audit trail more than you need catalog breadth.

#### Requesty — managed, enterprise-shaped

[Requesty](https://requesty.ai) is a fully managed gateway offering latency-based routing, automatic failover, prompt caching, role-based access control, and EU data residency. It targets the buyer who wants a vendor with a contract rather than a proxy to operate.

**Pick it if:** you want an SLA, EU residency, and someone to call.

#### Together AI and Fireworks — direct providers, not gateways

[Together AI](https://together.ai) and [Fireworks](https://fireworks.ai) appear in every "OpenRouter alternatives" list, so it is worth being precise about what they are. Both are inference providers that host open-weight models on their own hardware. They are not aggregators. You get one vendor's serving stack, consistent quantization, and no routing surprises, in exchange for a catalog limited to what they host.

**Pick them if:** you have standardized on one or two open models and you value serving consistency over selection. This is a genuinely good answer for a production workload that has stopped experimenting.

#### Cloudflare AI Gateway — a thin observability layer

[Cloudflare AI Gateway](https://developers.cloudflare.com/ai-gateway/) is a caching, rate-limiting, and analytics layer that sits in front of provider APIs you already hold keys for. It gives you no unified catalog and no unified billing. It is a different product that happens to rank for the same searches.

**Pick it if:** you already have direct provider keys and you want caching and visibility, not aggregation.

#### Bifrost — when proxy overhead is the constraint

[Bifrost](https://github.com/maximhq/bifrost) is a Go gateway that has made latency its headline claim: 11 microseconds of added overhead per request in a sustained 5,000 requests-per-second benchmark, across 23+ providers. Whether that matters depends entirely on your workload.

**Pick it if:** you run agent loops at scale, where a gateway adding 40ms per call compounds into hundreds of milliseconds of pure proxy latency across a single task.

## Which OpenRouter alternative should you choose?

Match the replacement to the reason you started looking. If fees drove you here, any gateway without a percentage cut works, and routing on top of it makes the savings bigger. Inconsistent output means you need provider control. Compliance means self-hosting or a governance vendor. Heavy agent traffic means weighting integration and routing above everything else.

**Fees are the problem.** Because OpenRouter does not mark up tokens, your savings come from removing the platform cut, not from finding cheaper model rates. Any gateway without a fee on top-ups keeps that 5.5% in your token budget. If you want savings bigger than the fee itself, routing is the lever: sending easy requests to a cheap model and reserving the premium tier for hard ones moves the bill far more than a few percent ever will. We covered the mechanics in [cutting inference costs with auto-routing](/blog/auto-routing-cut-inference-costs).

**Inconsistent model quality is the problem.** You need provider control: either a gateway that lets you pin the upstream, or a direct provider like Together AI or Fireworks that serves the model itself.

**Compliance is the problem.** Self-host LiteLLM, or buy governance from Portkey or a managed enterprise gateway. Read the privacy terms rather than assuming: a gateway call is two hops, so your effective data-retention policy is the union of the gateway's terms and the downstream provider's.

**Coding agents are most of your spend.** Weight the decision toward integration and routing, because that is where both the setup friction and the token bill live. If you are choosing models as well as a gateway, [the cheapest APIs for coding agents](/blog/cheapest-api-coding-agents) and [the best models for OpenClaw](/blog/best-models-for-openclaw) cover the model side.

**Nothing is actually broken.** Then stay. Switching gateways is cheap but not free, and OpenRouter is a good product. Curiosity is not a migration reason.

## How hard is it to migrate off OpenRouter?

Leaving is much easier than choosing. Every option on this list speaks the OpenAI API format, so migrating application code is a base URL and an API key, usually a two-line diff. Migrating a coding agent is one command. Nothing else in your stack changes.

For application code, point the OpenAI SDK at the new endpoint:

```python
from openai import OpenAI

client = OpenAI(
    base_url="https://api.haimaker.ai/v1",
    api_key="YOUR_KEY",
)
```

For coding agents, skip the config file entirely:

```bash
npx -y @haimaker/connect
```

That detects Claude Code, Codex, opencode, OpenClaw, Hermes, Cline, and Kilo Code, then writes the provider config for each one. The agent-side migration is where a manual switch usually stings, because every agent stores its provider settings somewhere different and in a different shape. Doing it by hand across three agents is an afternoon. Doing it with one command is the reason the agent audience is worth calling out separately.

That is the whole migration, both halves of it. Which means you can point an alternative at real traffic for a day, keep the old key warm, and decide on evidence rather than on a comparison table. Including this one.

## The bottom line

OpenRouter is not a bad product, and an honest version of this post has to say so. It has the biggest catalog, a real community, and a free tier that does a lot of good.

What it does not have is a fee structure that stays invisible at scale, deterministic provider routing, or an SLA. If one of those three is what brought you here, the fix is specific: remove the platform cut, take control of the upstream, or buy a contract.

And if your traffic is mostly coding agents, swapping one proxy for another is the smaller half of the win. Routing each request to a model that actually fits it is where the bill drops.
