What developers say about 9Router
Real reviews from devs who use it every day.
“Bought the Pro plan and used Claude Code all day without hitting quota. Key was activated within 2 minutes of payment. Support via Zalo is super fast.”
Hung Nguyen
Full-stack Dev · Hanoi
“Was constantly hitting Cursor Pro limits. Switched to 9Router and saved ~85% compared to the raw API. Auto-fallback between providers works great.”
Minh Tran
Indie Hacker · Ho Chi Minh City
“My team of 5 shares one endpoint, each with their own key for usage tracking. Clean dashboard, detailed logs — exactly what we needed.”
Linh Pham
Backend Engineer · Da Nang
“Rental key is cheaper and has a higher limit than Claude Max. Running Cline all day refactoring a 50k-line codebase — zero downtime.”
Thanh Vo
AI Researcher · Remote
“Used to get rate-limited mid-sprint. Now I code with Claude Code freely. Saving over $200/month compared to buying directly from Anthropic.”
Duy Le
Freelance Dev · Can Tho
“3 months running the Ultra plan for the whole team. 1/10th the price, 99.9% uptime as advertised. Strongly recommend.”
