// the problem

No-code frontends. Coded backends.

You've built the frontend. Now you need data. The options are either expensive, complex, or overkill.

/dev

Hire a Developer

Post on Upwork. Wait 2 days. Get quoted. Wait more. Get a half-built API that breaks when your sheet changes.

$500–$2,000 per API

Xano / Supabase

Schema design. Database tables. Relationships. Permissions. You wanted an API, not a database architecture course.

Hours of setup + learning curve

Google Sheets Alone

You're already in Sheets. The data is right there. But there's no way to expose it as a proper REST endpoint your tools can consume.

Data stranded. Can't connect.

// the solution

Sheet → API in 4 steps

No schemas. No servers. No SQL. Just your spreadsheet and a URL that works everywhere.

Connect Your Sheet

Paste your Google Sheets URL or upload a CSV. BuildAPI reads the headers automatically.

30 seconds

We Generate the API

Honest answers to real questions

How is this different from Xano? +

Xano is a full database + backend builder. It's powerful but requires you to design schemas, set up tables, define relationships, and learn their query language. BuildAPI is for one specific use case: your spreadsheet → REST API. If you already have data in Google Sheets and need a URL to expose it, BuildAPI does that in under 2 minutes. No schemas. No databases. No learning curve.

What happens when my Google Sheet changes? +

On the Pro and Agency plans, BuildAPI syncs with your sheet in real-time using Google's Sheets webhook. Add a row — it's in the API within seconds. Rename a column — the endpoint updates automatically. Free plan syncs every 15 minutes.

Can I use this with Bubble or Webflow? +

Yes — that's the primary use case. In Bubble, use the API Connector plugin. Paste your BuildAPI endpoint URL, add your Bearer token in the Authorization header, and map the JSON fields. In Webflow, use CMS or Memberstack with our webhook integration. Takes about 5 minutes per platform.

Is my spreadsheet data secure? +

We use read-only OAuth scopes for Google Sheets — we can never modify your original sheet without explicit write permission. All endpoints are secured with Bearer tokens. HTTPS everywhere. Data is encrypted at rest. We don't store your actual spreadsheet — we cache normalized JSON with a TTL you control.

Why not just use Google Sheets API directly? +

The Google Sheets API is powerful but developer-facing. It returns raw grid data, requires OAuth flows, doesn't support REST semantics like filtering/pagination, and has complex quota management. BuildAPI turns raw sheet data into a proper REST API with filtering, pagination, sorting, and auth — in the format that tools like Zapier, Bubble, and n8n expect.
