9router.com offers free API keys for multiple AI models, including GPT-5.6 and DeepSeek v4, with a smart fallback routing system to avoid rate limits. The service is promoted on Twitter with several free API key strings.
The project aims to solve AI coding subscription costs by aggregating providers and offering free tiers, as detailed in a Twitter thread by @_vmlops. Multiple free API keys were shared to attract users.
@_vmlops posts a thread explaining 9router's features: connects Claude Code, Cursor, etc. to 40+ providers with smart fallback, free tiers, RTK token saver, multi-account round robin, and works as local proxy, VPS, Docker, or Cloudflare Workers.
