OpenRouter alternatives split by what you want to stop paying for. Vercel AI Gateway charges no markup on tokens, LiteLLM and OmniRoute run on your own machine, Cloudflare AI Gateway adds free logging and caching, and a provider’s own API skips the middle layer entirely.

Before switching, look at two things that fix most OpenRouter bills without leaving. The 5.5% fee does not apply to the first $25,000 a month of bring-your-own-key traffic, and the cache misses behind many surprise bills have a documented fix.

How much does OpenRouter charge?

OpenRouter charges a 5.5% platform fee on pay-as-you-go credit purchases and passes model prices through at the provider’s rate, according to its pricing page. Bring-your-own-key traffic is free up to $25,000 of list-price inference per month, then carries a 5% fee.

The free plan offers 25+ free models from four free providers, capped at 50 requests a day. Enterprise contracts get fee discounts and raise the no-fee BYOK allowance to $200,000 a month.

The 5.5% applies to credits you buy from OpenRouter. If you already hold accounts with the providers, bring-your-own-key mode sends the same traffic through OpenRouter with no fee until list-price spend passes $25,000 in a month.

OpenRouter alternatives by the problem you want solved

Each option below removes a different part of what OpenRouter does, so start from the part you want gone.

Option	How it runs	Fee on tokens	Free allowance	Pick it when
OpenRouter	Hosted marketplace	5.5% on credits; BYOK free to $25,000/month, then 5%	25+ free models, 50 requests/day	You want one prepaid balance across many providers
Vercel AI Gateway	Hosted gateway	No markup, no platform fee	$5 credit per month	You want provider list prices with no fee layer
Cloudflare AI Gateway	Hosted proxy in front of your own providers	Core features free; providers bill you directly	100,000 stored logs on Workers Free	You need logs, caching and rate limits
LiteLLM	Self-hosted proxy or Python SDK	Free to self-host	Open source	Traffic has to stay inside your infrastructure
OmniRoute	Self-hosted gateway, MIT license	Free to self-host	Pools provider free tiers	You run coding agents and want free tiers first
A provider’s own API	Direct to one provider	Provider rates only	Varies by provider	Most of your traffic goes to one model family

Vercel AI Gateway: list prices, no platform fee

Vercel AI Gateway charges no markup and no platform fee on tokens; you pay the provider’s list price from prepaid credits, per Vercel’s pricing docs. Every Vercel team gets $5 of free credit a month for free-tier models, and bring-your-own-key is available on the paid tier, also at zero markup.

The gateway lives inside Vercel’s platform, so it fits best when your app already deploys there.

LiteLLM: a proxy you run yourself

LiteLLM is an open-source AI gateway that calls 100+ LLM providers through the OpenAI request format, either as a Python SDK inside your code or as a proxy server shared by a team, per its GitHub repository. Nothing leaves your infrastructure except the calls to the providers themselves, which is the reason teams with data-residency rules choose it. You also take on the operations work: upgrades, uptime and key storage become yours.

OmniRoute: free tiers for coding agents

OmniRoute is an MIT-licensed gateway you host yourself, built around coding tools such as Claude Code, Codex and Cursor. Its README lists 352 providers and a free-tier catalog it puts at about 1.51 billion tokens a month, re-audited every two weeks, and the repository has passed 64,000 GitHub stars since it launched in February 2026.

Two cautions come with it. In a hands-on test by Pinggy, only two of seven no-login free providers answered, and the dashboard password defaults to the literal string CHANGEME until you set INITIAL_PASSWORD. The OmniRoute guide walks through setup and those settings.

Cloudflare AI Gateway: logs and caching at no charge

Cloudflare AI Gateway sits in front of providers you already pay and adds dashboard analytics, caching and rate limiting, which Cloudflare offers free on all plans, per its pricing reference. Stored logs are capped at 100,000 in total on the Workers Free plan and 10 million per gateway on Workers Paid. You still hold an account with each model provider, because Cloudflare’s gateway adds control on top of them and does not sell model access itself.

Going direct: a provider’s own API

When most requests go to one model family, that provider’s API removes every middle layer, along with its fees and its routing decisions. The trade is losing automatic fallback when that provider has an outage.

For free chat and roleplay use, the community view still favors OpenRouter:

“For free models openrouter is your best bet. Nanogpt is the other popular option if you can put down a subscription.”

Why OpenRouter bills jump on cached models

One recurring complaint about OpenRouter bills is prompt-cache misses caused by provider routing. This one comes from a developer running a small SaaS product:

“For a small saas project with AI I noticed openrouting is sucking my credits crazy Compared for example to deepseek api Same task +5$ gone in openrouter Deepseek still under 0.5$ The problem is the cache openrouter keeps switching me to other providers with terrible cache hits I’ve tested to blacklist providers and keep few good ones but it’s still keep switching between them causing me to pay full prices for the tokens. Any recommendations ?”

A prompt cache only pays off when the same provider sees your repeated prompt. OpenRouter handles this with provider sticky routing, described in its prompt caching docs: after a cached request, later requests for the same model go back to the same provider while the session stays active. Four conditions break that:

• Setting a manual provider order with provider.order turns sticky routing off, because your explicit order takes priority.
• A sticky session expires after 10 minutes without a request.
• OpenRouter identifies a conversation by hashing the first system message and the first non-system message, so changing either one starts a new session. Sending a session_id pins the session explicitly.
• Stickiness only activates when the provider’s cache-read price is lower than its normal input price.

Blacklisting providers, which that developer tried, narrows the pool but still leaves OpenRouter choosing among the rest, which matches the switching they describe. The documented levers are a stable opening prompt, a session_id, and no manual provider order.

The price gap explains why the misses hurt. On DeepSeek’s own API, deepseek-flash input is billed at $0.003 per million tokens on a cache hit and $0.15 on a miss at off-peak rates, a 50-fold difference, per DeepSeek’s pricing page. An agent that resends a 100,000-token context 200 times a day moves 20 million input tokens: about $0.06 when every call hits the cache and $3.00 when every call misses, before output tokens. Peak-hour rates are double.

If fixing the session does not bring the cache hits back, that is the point where a direct provider API or a self-hosted gateway you control earns the switch.

FAQ

Is there anything better than OpenRouter?

For zero platform fees, Vercel AI Gateway charges no markup on tokens; for self-hosting, LiteLLM and OmniRoute are free open-source gateways. OpenRouter keeps the advantage of one prepaid balance across many providers, so the better choice depends on whether fees, control or convenience comes first for you.

Is OpenRouter an LLM gateway?

Yes. OpenRouter is a hosted LLM gateway and marketplace: one OpenAI-compatible API in front of many model providers, with fallback between providers and a single prepaid balance.

Are there free OpenRouter alternatives?

Yes. LiteLLM and OmniRoute are free to self-host, Vercel AI Gateway includes $5 of free credit a month, and OpenRouter’s own free plan offers 25+ free models at up to 50 requests a day. Self-hosted gateways still pass through whatever the underlying providers charge.
