A documented comparison. No paid-account testing.

OpenRouter alternatives solve different problems. AIGROW sells credit for Claude, GPT, Gemini and Grok models below their makers’ list prices; the Anthropic and OpenAI APIs charge list price with no fee on credit; LiteLLM is an open-source gateway you run yourself. None of them serves OpenRouter’s 500+ models, so check the models you use first.

Which one fits your work?

Start from your bill. If most of it is Claude, GPT, Gemini or Grok, a cheaper route to those models saves the most. If you need many open models or free ones, OpenRouter’s range is hard to replace. If you want control over keys, budgets and logs, a gateway you host may fit.

Keep OpenRouter when you rely on models or providers the alternatives do not serve, or on its automatic fallback between providers. Moving only part of your traffic is a valid choice.

AIGROW API credit

Claude, GPT, Gemini and Grok models below their makers’ list prices

Visit AIGROW API credit

AIGROW sells prepaid credit for one endpoint that serves current models from Anthropic, OpenAI, Google and xAI. Credit sells below its face value: $25 buys $100, so each model costs up to 75% below its maker’s list price, and no rate is above list. The endpoint takes Anthropic and OpenAI style requests, so Claude Code, Cline and the official SDKs work with a new base URL and key.

Best reason to choose it: A stronger fit when most of your spend goes to Claude, GPT, Gemini or Grok models and you want the same tokens for less than list price, by monthly plan or one-off pack.
Check before you choose: AIGROW is independent of the model makers, and its price table lists every model it serves. It works with tools that send Anthropic or OpenAI chat requests; Codex sends Responses API requests, so run Codex on the maker’s own API.

Anthropic and OpenAI APIs

Buying straight from the model makers

Visit Anthropic and OpenAI APIs

Anthropic and OpenAI each sell API access by the token, priced per million tokens on their own pricing pages. Both list a lower rate for batch requests that can wait and a lower rate for cached input. Each maker is its own account, key, bill and set of rate limits.

Best reason to choose it: A stronger fit for batch jobs, for every model and API feature each maker sells, and for teams that need an account directly with the maker.
Check before you choose: Tokens cost the list price, and every maker you use is a separate account and bill. Compare the batch and cache rates for your own workload before you choose.

LiteLLM

An open-source gateway you host yourself

Visit LiteLLM

LiteLLM is an MIT-licensed library and a self-hosted, OpenAI-compatible proxy for 100+ model providers. Its documentation describes cost tracking per key, team and user, budgets and rate limits per team, load balancing and automatic fallbacks. You connect your own provider accounts and pay each provider.

Best reason to choose it: A stronger fit for an engineering team that wants one gateway under its own control, with spend limits per team, and is ready to run it.
Check before you choose: You host, update and monitor the proxy yourself, and tokens still cost each provider’s list price. LiteLLM also promotes an Enterprise edition; ask about its terms before you plan around it.

How we made this comparison

Published by AIGROW, which is included in this guide. We reviewed public product pages, pricing pages and help documentation, not paid accounts, and each profile shows the date we checked it. The roundup lists tools alphabetically, with no overall ranking or performance score. Recommendations are our assessment of fit, not hands-on benchmarks. Features and access can change; confirm requirements with each provider.

For a fair test, send the same requests to the same model through each route. Compare what each one billed, including any fee on the credit you bought, and check the errors and retries your tools rely on.

OpenRouterAIGROW vs OpenRouter OpenRouter alternatives

Before choosing a tool

AIGROW sells API credit below its face value, and its price table shows each model’s rate beside the maker’s list price. OpenRouter and the makers’ own APIs bill tokens at list price, and OpenRouter adds a fee when you buy credit.

Usually only the base URL, the key and the model ids. OpenRouter, AIGROW and LiteLLM all take OpenAI-style requests. Model ids differ between services, so check each one’s model list before you switch.

Price your own usage

The AI API page lists every model AIGROW credit covers beside its maker’s list price. Type your monthly spend into its preview to see what credit would cost.
