OpenRouter made one API key for hundreds of models the default way to work with LLMs. The catch is in the billing. OpenRouter charges a 5.5% fee on card credit purchases (with a $0.80 minimum), 5% on crypto purchases, and a 5% fee on bring-your-own-key usage after the first 1 million requests a month. Its terms also reserve the right to expire unused credits after one year.
On a $100 top-up, that leaves about $94.50 to spend on inference. On a $5 top-up, the $0.80 minimum works out to 16%. You also need an account before you can send a single request.
The alternatives below remove some or all of that friction. We ranked them on cost, privacy, model access and setup effort.
| Platform | Best For | Platform fee | Account needed | Starting price |
|---|---|---|---|---|
| NanoGPT | Lowest-cost, private model access | None on deposits; text models at list price; 3% bonus on crypto top-ups | No | $0.10 crypto or $1 card |
| Vercel AI Gateway | Teams on Vercel | No token markup, including BYOK | Yes | $5 free credit per month |
| LiteLLM | Self-hosting | None (you pay providers directly) | Self-managed | Free, open source (MIT) |
| Requesty | EU data residency | 5% markup; 0% on BYOK | Yes | Free tier: 200 requests/day on free models |
| Cloudflare AI Gateway | Free analytics and caching | 5% on Unified Billing credits | Yes | Core features free |
| Portkey | Production governance | Billed per recorded log | Yes | Free 10K logs/month; $49/month Production |
| OpenRouter (baseline) | Prototyping | 5.5% on card top-ups ($0.80 min); 5% on crypto | Yes | Prepaid credits |
Methodology: We compared each platform on four criteria: the total cost of funding usage (top-up fees plus any token markup), privacy (whether an account is required and how data is handled), model coverage, and setup effort. Pricing was checked against each vendor's published pricing page in October 2026. Fees change often, so confirm current rates before you commit.
Best For: Developers and individuals who want the widest model catalog at list price, without top-up fees or handing over personal details.
NanoGPT is a pay-as-you-go platform that puts about 1,000 text, image, video, 3D, audio and embedding models behind one OpenAI-compatible API and one balance. It solves OpenRouter's two biggest pain points directly: the fee on the way in, and the account you need before you start.
Text models are billed at each provider's list price with no markup. GPT-5.5 costs $5 input and $30 output per million tokens on NanoGPT, the same as at OpenAI. Deposits carry no percentage fee by card or crypto, so a $100 deposit is $100 of usable balance. Crypto users get more: top-ups paid in crypto receive a 3% bonus, so $100 in crypto becomes $103 of balance. Compared with OpenRouter's 5% crypto fee, that is roughly an 8% swing on every crypto top-up.
Privacy is where NanoGPT stands apart. You can start an anonymous session and use the web app without creating an account. Developers can call supported API endpoints with no account or API key at all, paying per request through accountless crypto payments, including Bitcoin Lightning. Minimum deposits start at $0.10 in crypto or $1 by card, and an optional $12/month Pro plan bundles 60M input tokens a week on open-weight models.
Programming Insider's comparison of OpenRouter alternatives by use case also ranks NanoGPT first, for model access.

Best For: Teams building with the Vercel AI SDK who want zero-markup routing inside the platform they already deploy on.
Vercel AI Gateway routes requests to hundreds of models from one endpoint and bills at the provider's list price. Vercel adds no markup on tokens on either the free or paid tier, and none on bring-your-own-key traffic either. Every Vercel team account receives $5 of AI Gateway credit every 30 days after its first request, which covers light testing for free.
You do not need to deploy on Vercel to use it, but apps that do can authenticate with OIDC tokens instead of managing API keys. Each response returns its exact cost, which makes spend easy to audit.
Pros:
Cons:
Best For: Engineering teams that want full control over the routing layer and are comfortable running their own infrastructure.
LiteLLM is an MIT-licensed proxy that puts dozens of LLM providers behind one OpenAI-compatible interface. You run it yourself, typically backed by Redis and Postgres, and get virtual keys, budget tracking and usage logs without a third party in your request path. Because you pay each provider directly, there is no gateway markup at all.
Pros:
Cons:
Best For: European teams that want a managed, OpenRouter-style router with data kept in the EU.
Requesty routes across 600+ models with caching, fallbacks, spend limits and analytics. Pricing is a flat 5% on top of model cost: a model priced at $10 per million tokens costs $10.50 through Requesty. Bring your own provider keys and the markup drops to 0%. A free tier offers 200 requests a day on free models with no card, and traffic, logs and analytics can stay on EU infrastructure in Frankfurt.
Pros:
Cons:
Best For: Teams that already call providers directly and want free caching, analytics and rate limiting in front of them.
Cloudflare AI Gateway sits between your app and your model providers. Its core features, including dashboard analytics, caching and rate limiting, are free on every Cloudflare plan, and data loss prevention scanning is free too. Persistent logs are capped at 100,000 total on the Workers Free plan and 10 million per gateway on Workers Paid.
If you would rather not hold accounts with each provider, Unified Billing lets you buy Cloudflare credits and spend them across providers. Provider prices pass through with no markup, but a 5% fee applies to the credits you buy.
Pros:
Cons:
Best For: Teams moving from prototype to production that need guardrails, fallbacks and an audit trail on every LLM call.
Portkey is an AI gateway with observability built in. It adds retries, fallbacks, load balancing, caching, guardrails and prompt versioning across 250+ providers, and its gateway core is open source and self-hostable. The hosted service bills on recorded logs: the free Developer plan includes 10,000 logs a month, and the Production plan costs $49/month for 100,000 logs, then $9 per additional 100,000.
Pros:
Cons:
Start with the reason you are leaving OpenRouter. Most people leave over fees, privacy or control, and each points to a different pick.
NanoGPT is the best OpenRouter alternative for most developers and individuals. It bills text models at provider list price with no deposit fees, adds a 3% bonus on crypto top-ups, offers about 1,000 models across text, image, video and audio, and can be used without creating an account.
Yes. OpenRouter charges 5.5% on card credit purchases with a $0.80 minimum, and 5% on crypto purchases. Bring-your-own-key usage is free for the first 1 million requests a month, then carries a 5% fee.
NanoGPT and Vercel AI Gateway both bill models at provider list price. NanoGPT also charges no deposit fee on card or crypto top-ups. Self-hosted LiteLLM has no markup because you pay providers directly.
Yes, with NanoGPT. You can use its web app in an anonymous session, and supported API endpoints accept accountless payments in crypto, including Bitcoin Lightning, with no API key required.
NanoGPT. It gives a 3% bonus on crypto top-ups and accepts deposits from $0.10, while OpenRouter charges a 5% fee on crypto credit purchases.
Yes. LiteLLM is a free, MIT-licensed proxy you run on your own infrastructure. Portkey's gateway core is also open source and self-hostable.
OpenRouter is still a fine place to prototype, but its 5% to 5.5% top-up fee and account requirement add up as usage grows. If you want one API for every major model without that overhead, NanoGPT is the strongest pick: list-price text models, no deposit fees, a 3% bonus on crypto, and no account needed to get started. Teams with narrower needs are well served by Vercel AI Gateway, LiteLLM, Requesty, Cloudflare AI Gateway or Portkey, depending on whether they value ecosystem fit, self-hosting, EU residency, free analytics or governance.
