UnoRouter vs nano-gpt: chat marketplace or one key for both
nano-gpt offers a huge model catalog behind a chat UI. UnoRouter gives you the same pay-as-you-go access plus a real developer API and a built-in character client, under one clean key.
nano-gpt and UnoRouter both offer pay-as-you-go access to a lot of models, no subscription. nano-gpt leads with breadth behind a chat marketplace. UnoRouter leads with one OpenAI-compatible key that works in a coding agent and a chat client. Same credits, two different front doors.
Catalog
nano-gpt's pitch is size: hundreds of text and image models to try. UnoRouter runs 200+ models across the providers that matter for coding and character chat, curated and kept current instead of maximized for a count. Want raw breadth? nano-gpt wins that. Want the models people actually ship on? The gap closes fast.
The developer story
A chat marketplace is built UI-first, with the API as a side door. UnoRouter is OpenAI-compatible by design. Point any SDK at https://api.unorouter.com/v1, keep your code, and the same key drives Claude Code, Cline, OpenCode, or Codex. You are using a gateway that also has a chat client, not an API bolted onto a chat site.
The chat side
Both let you chat in the browser, but UnoRouter's client is built for character chat: personas, lorebooks, presets, SillyTavern card import, and the same key drops into SillyTavern, Janitor.AI, or Chub for a heavier frontend. You are never locked into one UI, and the credits follow you.
Price and keys
Both are pay-as-you-go, the right model for bursty multi-model use. UnoRouter keeps it to one balance, credits that never expire, free tier, one key across coding and chat instead of a marketplace wallet you spend in one UI. Same billing shape; the difference is how far the one key reaches.
How to pick
Mostly want a web UI to sample the widest model list? nano-gpt is good at that. Want one key that works in your coding agent and a real character client, with credits that travel? UnoRouter.

Wearing the UnoRouter Discord tag shortens your free-model rate limit window by 25 percent, so a model you could call once a minute you can call every 45 seconds.
