Browser extension for hoarders of cheap AI API keys

What it does

All API Hub is a browser extension that wrangles multiple AI API proxy accounts—those “recharge-card supermarkets” for discounted ChatGPT, Claude, and friends. It tracks balances, usage, and model prices across sites, auto-checks in for free credits, and exports credentials to tools like CherryStudio and Claude Code Router. Think of it as a portfolio manager for your scattered API keys.

The interesting bit

The plugin auto-detects which proxy architecture a site runs (One-API, New-API, Sub2API, etc.) and adapts accordingly. It also sniffs API keys and base URLs directly from web pages, popping up a test window without manual copy-paste. For the truly committed, it can push accounts into your own self-hosted backend as channels with model redirection and sync.

Key highlights

• Cross-site balance and usage dashboard with health checks
• Price comparison across models and sites to find cheapest routing
• Automated daily check-in for free credits on supported platforms
• One-click export to ~10 third-party tools (cc-switch, CLIProxyAPI, Kilo Code, etc.)
• Cloudflare challenge bypass to keep automated refreshes from breaking
• Local-first credential storage; optional encrypted WebDAV sync

Caveats

• Safari requires manual Xcode compilation; mobile support is limited to Edge/Firefox/Kiwi
• Data compatibility with the older One API Hub exists, but the README notes a “major refactor”—migration friction is unclear

Verdict

Worth a look if you’re running three or more API proxy accounts and tired of spreadsheet bookkeeping. Skip it if you pay list price for one OpenAI key and call it a day.
