The sky is the limit

Layer 2

Sheet_FireWall

Auth, validation, rate limiting & routing. Your invisible security guard.

Why GSheetBridge

Everything you need.
Nothing you don't.

Most data bridges are over-engineered. GSB gives you a production-grade connection in three lines of code.

Core

Three lines. That's it.

Initialize, read, write. No SDK ceremony, no auth dance, no twelve-step config wizard.

const gsb = new GSheetBridge('your-api-key');
const data = await gsb.read('Sheet1'); // Sheets → App
await gsb.write('Sheet1', row); // App → Sheets

Security

Sheet_FireWall

Every request passes through authentication, data validation, and rate limiting before touching your Sheets.

Security layers

Raw API exposure

Sync

Real-time both ways

Edit a cell in Sheets, see it in your app. Submit a form in your app, see it in Sheets. Instant.

Scale

Multi-tenant SaaS ready

Built-in tenant isolation, per-user rate limits, and configurable access control. Deploy once, serve many.

How It Works

Three steps.
Five minutes.

From zero to production-ready data bridge. No servers. No databases. No DevOps.

Drop in the SDK

Add a single JavaScript snippet to your web app. Initialize with your API key. That's your entire backend — done.

< 2 minutes

FireWall validates everything

Every request is authenticated, validated, rate-limited and routed through the Sheet_FireWall. You configure the rules — we enforce them.

automatic

Data flows both ways
