Building AI tooling infrastructure in China. CCSub solves one concrete problem: letting developers in China use full-strength Claude, GPT, and Gemini models inside Claude Code, Cursor, and Codex CLI at 30–60% lower cost than the official APIs.
Why CCSub exists
In late 2025, Claude Code took off among Chinese developers, but the official API doesn't accept Chinese cards, direct connections are unstable, and heavy users hit five-hour cooldowns. Existing relays were either expensive, stripped prompt caching, or skipped invoicing. CCSub set out to do all of this correctly at once: ¥1 = $1 of API balance, full cache_control passthrough, PAYGO + monthly + Bedrock enterprise tiers, and a domestic-China-friendly billing stack (WeChat / Alipay / USDT / bank transfer + VAT invoices).
Stack
- Frontend: Next.js 15 App Router, React 19, Tailwind 4, shadcn/ui
- Backend: Vercel Fluid Compute, PostgreSQL (Neon serverless), Drizzle ORM
- Upstream routing: Anthropic native, AWS Bedrock, Claude Max reverse pool, Kiro pool, OpenAI
- Protocol adapters: bidirectional Anthropic Messages ↔ OpenAI Chat Completions ↔ Responses
- Auth: Better Auth + Google OAuth + Magic Link
