SheetSandbox 2.0 - Turn Google Sheets into a REST API — SDKs, Playground & More

Hey Product Hunt! 👋 I'm Aravind — solo builder of SheetSandbox. I launched v1 here a few months ago, and today I'm back with v2. The core idea hasn't changed: connect a Google Sheet, get a bearer-token-authenticated REST API (GET + POST) instantly. No backend. No database setup. No cloud infra. But v2 ships a lot of new stuff based on what 400+ users actually needed: -- 🛠 Node.js + Python SDKs -- npm install sheetsandbox / pip install sheetsandbox -- Type-safe, promise-based, zero config. If you're using the raw fetch API today, this is a straight upgrade. 🧪 API Playground (in-dashboard) Test GET and POST endpoints without leaving the browser. No Postman, no curl. Pick method → enter tab name → see live JSON response. 🔄 One-click token rotation Leaked a bearer token? Hit the refresh icon. Old token dies immediately. New one ready to copy. 3 seconds. 📊 Live analytics Per-project usage bars (black → yellow at 70% → red at 90%), overall utilization, most active project. All real data, no mocks. 🚨 Rate limit email alerts Auto email when any project hits 80% of its daily limit. You get the warning before your users get the error. 🔓 Full dashboard on free plan Log in, explore the playground, read the docs, test the API. No redirect to an upgrade wall. You only hit a gate when creating a project. Who it's for: indie devs building waitlists, feedback forms, contact pages, or any simple data collection where a real database is overkill. Pricing: $6.99 once. 5,000 API calls/day. Unlimited Google Sheets. All future updates. No subscription, ever.
