How do I connect Google Sheets to a web app without a backend?

With GSheetBridge, you can connect Google Sheets to any web app without writing backend code. Add the GSheetBridge SDK to your HTML, initialize it with your API key, and start reading or writing Sheets data directly from your JavaScript frontend. The entire setup takes under 5 minutes.

Does GSheetBridge work with React, Vue, or vanilla JavaScript?

Yes. GSheetBridge is framework-agnostic. The JavaScript SDK works with React, Vue, Angular, Svelte, or any vanilla JS project. Any frontend that can run JavaScript and make HTTP requests can use GSheetBridge.

Can I use Google Sheets as a database for my web app?

Yes. GSheetBridge lets you use Google Sheets as a lightweight database or data backend for your web app. It supports real-time reads, writes, and bidirectional sync. It is best suited for SMB tools, internal dashboards, MVPs, and SaaS prototypes where Google Sheets is already the source of truth.

Q: What is GSheetBridge?

GSheetBridge is a developer tool that connects any web app to Google Sheets with real-time two-way (bidirectional) data sync. It lets you read and write Google Sheets data directly from your frontend using just 3 lines of JavaScript — no backend, no server, no database required.

Q: How does GSheetBridge work?

GSheetBridge works as a secure middleware layer between your web app and Google Sheets. You initialize the SDK with your API key, then call gsb.read() or gsb.write() from your frontend. Every request passes through Sheet_FireWall — a 3-layer security system handling authentication, data validation, and rate limiting — before reaching your Sheet.

Q: Is GSheetBridge secure?

Yes. GSheetBridge uses a built-in security layer called Sheet_FireWall that handles authentication, input validation, rate limiting, and origin allowlisting. Your Google Sheets API credentials are never exposed to the browser. All requests are routed through GSheetBridge's secure cloud infrastructure.

Q: What is Sheet_FireWall?

Sheet_FireWall is GSheetBridge's built-in security layer. It sits between your web app and your Google Sheet, automatically handling API key authentication, request validation, per-user rate limiting, and CORS origin control. You configure the rules once — Sheet_FireWall enforces them on every request.

Q: How much does GSheetBridge cost?

GSheetBridge offers a free plan with 1 Sheet connection and 500 API calls/day. Paid plans start at $9.90/month (Pro) and $29/month (Business). No credit card is required to start.

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.

What is GSheetBridge?

GSheetBridge is a developer tool that connects any web app to Google Sheets with real-time, bidirectional data sync. You read and write Sheets data directly from your JavaScript frontend — no backend, no server, no database required. The entire integration takes 3 lines of code and under 5 minutes.

How does GSheetBridge work?

You initialize the SDK with your API key (new GSheetBridge('your-api-key')), then call gsb.read() or gsb.write() from your frontend. Every request is routed through Sheet_FireWall — GSheetBridge's built-in 3-layer security system — before it reaches your Google Sheet. Your credentials never touch the browser.

Is GSheetBridge secure? My Sheet contains sensitive data.

Yes. Sheet_FireWall sits between your app and your Sheet and handles API key authentication, input validation, per-user rate limiting, and CORS origin control on every single request. Your Google Sheets API credentials are stored server-side and are never exposed to the browser. You configure the access rules — GSheetBridge enforces them automatically.

What is Sheet_FireWall?

Sheet_FireWall is GSheetBridge's invisible security guard. It runs on every request between your web app and your Google Sheet, enforcing: authentication (valid API key check), data validation (schema and type checking), rate limiting (per-user call quotas), and origin allowlisting (CORS control for Pro users). You set it up once in your dashboard — it works silently from there.

Does it work with React, Vue, or plain JavaScript?

Yes — GSheetBridge is fully framework-agnostic. The SDK is plain JavaScript and works in any frontend environment: React, Vue, Angular, Svelte, or vanilla JS. If your project can run JavaScript and make HTTP requests, it works with GSheetBridge.

Can I use Google Sheets as a database for my SaaS?

Yes, and it's one of GSheetBridge's most popular use cases. Sheets works excellently as a lightweight, collaborative backend for internal tools, client portals, admin dashboards, and SaaS MVPs — especially when your team or clients are already managing data in Sheets. GSheetBridge adds the real-time sync layer and security that the raw Sheets API doesn't provide out of the box.

How much does GSheetBridge cost?

GSheetBridge offers a free plan forever — 1 Sheet connection, 500 API calls/day, no credit card required. Paid plans are Pro at $9.90/month (10,000 API calls/day, 10 Sheets, GSB Studio access) and Business at $29/month (100,000 API calls/day, unlimited Sheets, priority support, custom domain). You can upgrade, downgrade, or cancel anytime.

What happens after my free trial ends?

After the 30-day free trial, you can choose a paid plan to continue. If you don't upgrade, your API access is paused — your data in Google Sheets remains completely untouched. You can reactivate anytime by subscribing. There's no vendor lock-in and no data loss.
