About

OpenRouter is an AI model routing platform that gives developers access to hundreds of models through a single unified API. It connects users with models from providers such as OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek, Qwen, xAI, and many others. The platform supports text, image, video, and audio generation while allowing developers to use one API key and a consistent interface across providers. OpenRouter can route requests based on price, performance, and availability, with fallback options that help maintain service when a provider experiences downtime. It also offers configurable data policies so organizations can control which providers receive prompts and how requests are handled. Developers can purchase credits, choose from more than 500 active models across over 80 providers, and integrate OpenRouter using an OpenAI-compatible API.

About

Zerouter is a hosted AI API gateway for developers building applications and coding workflows with large language models. It provides one API key and a configurable base URL for sending requests to models from Anthropic (Claude), OpenAI (GPT), Google (Gemini), xAI (Grok), and Moonshot AI (Kimi). The gateway exposes OpenAI-compatible and Anthropic-compatible endpoints, allowing supported SDKs and clients such as Claude Code, Codex CLI, and Cursor to connect with a custom endpoint rather than managing separate provider connections. Users can select model IDs, view published per-token rates, and review request-level usage and charges. Zerouter uses pay-as-you-go billing based on input and output token use, with no subscription or monthly minimum. It is aimed at software developers and technical teams integrating hosted LLMs into apps, coding agents, and other API-based workflows.

Pros & Cons from Real Users

Pros

  • Instead of getting married to ChatGPT or Claude and being locked into that relationship, OpenRouter is way more polyamorous. LMAO. And it's less messy than the real life relationship version. I can use different LLMs for different types of tasks and you learn quickly which LLMs excel in certain areas. In the beginning I did multichats where I'd ask 1 question to 2 or 3 bots at a time (their multichat features) and whoever gave the best answer was who I continued interacting with. I guess it's more like speed dating than polyamory. But the bottom line is, instead of spending $20-$30/mo with one system, I am spending a la carte, which is WAAAAYYYY cheaper, and using the right tool at any given moment. It just takes discipline to copy and paste your chats elsewhere. It does give you a copy markdown button to make it easier. And if you enable markdown in Google docs, there is a paste as markdown feature that makes it look like RTF when it's pasted in, with no codes. Because the chats are browser bound, they are stuck on one computer and everybody is on a bunch of different devices these days. So pasting into Google Docs is the best bet for portability all around. Privacy isn't an issue, because they aren't storing your chats! For some people, this is a big plus. To use the service, they charge you a 9 or 10% charge for however much money you put towards tokens. So if I refill for $10, the total is $10.90, with $10 of usable token for whichever LLM I feel like using. Keep in mind, there are free LLMs too which you can choose and never pay. When you add models, type 'free' in the search box and you'll see several free, from Maverick to Scout to Gemma, etc. It will make you feel like a serious power user and you'll feel smarter everytime you use it. It also has access to the secret parameters that the online LLMs don't show you, like Temperature, Top P, Frequency penalty, etc. It can save you money if you tell it ahead of time what type of vocab you like or how divergent you want the suggestions to be, vs. training ChatGPT or Gemini manually.

Cons

  • The chats aren't persistent - you must copy and save them elsewhere before you close a browser window, or all that info from that chat is gone.
