OpenRouter alternatives

Compare LiteLLM, Vercel AI Gateway, Cloudflare AI Gateway, and Requesty as OpenRouter alternatives by hosting, fees, data residency, and spend controls.

What do you need to change?

Teams usually look beyond OpenRouter for one of three reasons: prompts need to stay inside their own infrastructure, they want to stop paying a fee on top of provider rates, or they need tighter control over regions and spend per team. LiteLLM is the self-hosted option, Vercel AI Gateway charges no platform fee on tokens, Cloudflare AI Gateway adds free caching and analytics in front of providers you already pay, and Requesty includes EU data residency on every plan.

Four alternatives to consider

AI model gateways

LiteLLM

Consider LiteLLM when prompts must stay in your own cloud or an air-gapped network, and you have engineers to run an MIT-licensed gateway with virtual keys and budgets.

An open-source AI gateway and Python SDK that calls 100+ LLM providers in the OpenAI format, self-hosted with virtual keys, budgets, and an admin UI.

Pricing model
The gateway and SDK are MIT-licensed and free to self-host; you pay providers directly with your own keys. An Enterprise licence adds SSO beyond five users, SCIM, audit logs, and support SLAs, with a 30-day free trial.
Before choosing
You deploy, update, and secure the gateway yourself, and SSO is free only for up to five users; price the Enterprise licence if you need it across the organisation.
AI model gateways

Vercel AI Gateway

Consider Vercel AI Gateway when you build with the AI SDK or already use Vercel, and want provider list prices with no platform fee on tokens.

Vercel's managed gateway for calling models across providers through one API, with budgets, logs, model fallbacks, and bring-your-own-key support.

Pricing model
No markup or platform fee on tokens: you pay the provider's list price from prepaid AI Gateway Credits. Every team gets a small monthly free credit for a subset of models with lower rate limits, and buying credits moves you to the paid tier. Bring-your-own-key use has no fee but requires purchased credits.
Before choosing
Buying credits ends the monthly free credit, and AI Gateway budgets exclude bring-your-own-key spend, so set spending limits with the provider as well.
AI model gateways

Cloudflare AI Gateway

Consider Cloudflare AI Gateway when you mainly want caching, rate limiting, analytics, and logs in front of the provider accounts you already have, with core features free.

A gateway on Cloudflare's network that sits in front of your AI providers, adding analytics, logging, caching, rate limiting, and model fallbacks.

Pricing model
Core features, including analytics, caching, and rate limiting, are free on all plans. Log storage depends on your Workers plan, and Unified Billing adds a 5% fee on credits bought through Cloudflare, with provider rates passed through without markup.
Before choosing
Stored logs are capped on the Workers Free plan, and accounts created recently follow Workers Logs pricing; estimate log volume before relying on it for audit trails.
AI model gateways

Requesty

Consider Requesty when you need a hosted, OpenAI-compatible gateway with EU data residency, regional endpoints, and spend limits per key on every plan.

A hosted, OpenAI-compatible LLM gateway for 600+ models, with routing, fallbacks, caching, spend limits, and EU data residency on every plan.

Pricing model
A free plan covers free models with 200 requests a day and no card. Pay as you go adds 5% to model cost, with no seat pricing or minimum spend, and supports your own provider keys. Enterprise adds SSO, RBAC, audit logs, and custom SLAs.
Before choosing
The 5% markup applies to model cost on pay as you go; ask how requests made with your own provider keys are billed before migrating.

When OpenRouter may still fit

Keep OpenRouter on the shortlist when you want hundreds of hosted models behind one key and one balance, with automatic fallbacks across providers. Its fee is charged when you buy credits rather than per request, and on paid plans bring-your-own-key traffic is free up to a monthly allowance.

Free models are capped per minute and per day, and EU or US in-region routing needs the Business plan or above; add the fee on credit purchases when you compare costs.

Before you switch

  1. List the models and providers you call today, and confirm each candidate supports them, including tool calling and streaming.
  2. Work out the total cost at your monthly volume: provider rates plus any fee on credits, markup, or bring-your-own-key charge, or the cost of running a self-hosted gateway.
  3. Force a provider failure in a test, then check what each gateway retries, what it logs, and whether the failed attempt is billed.
