Sheet Ninja turns any Google Sheet into a live API in seconds. Your data already exists. Stop rebuilding it in clunky databases. Paste a link, get endpoints. Build with Lovable, Bolt, or Replit and your data stays in Sheets. Your clients edit like a spreadsheet. Your app reflects it instantly. No backend, no redeployments, no calls from confused clients.
Thrilled to hunt the Sheet Ninja team on their Product Hunt launch.
Sheet Ninja is the backend vibecoders already have.
This isn't "connect your tools,". This is starting with where your data actually lives, and building on that foundation.
The unlock is treating Google Sheets as a first-class API. One that agents, apps, and non-technical clients can all read and act on.
Your app gets live endpoints. Your clients get a spreadsheet. Nobody has to redeploy to change a price.
This adds up to:
- Instant API from any Sheet. Paste a link, go build.
- Works out of the box with Lovable, Bolt, Replit, v0, and Cursor. No new tools to learn.
- Full CRUD support: read, write, update, delete. Your Sheet is your database.
If you're building with AI coding tools or tired of rebuilding data your clients already manage in Sheets. Sheet Ninja is the missing layer between your spreadsheet and your app.

Really cool idea! Reminds me of how levels.fyi was running their whole operation from a Google Sheet for a pretty long time.
Going beyond the basics - can you also write back to the sheet and how does authentication work?
This is interesting. I work with large spreadsheets for tracking things like invoices and cancellations, and managing that manually becomes painful at scale.
Could this help automate those kinds of workflows and keep everything in sync without extra effort?
Thanks for launching, it’s been a useful product for me. I’ve used Sheet Ninja on some products i’ve been playing around with on Replit and found the tool useful for the database side and keeping data in Google Sheets. Keep it up and looking forward to new features!
I build a lot of small apps and most of the time I have to import data into wherever I'm building it. Sheet Ninja is much simpler. Just created a test app and it worked immediately.
The live API from Google Sheets idea is genuinely clever. Curious how it holds up when clients start editing data simultaneously from different tabs. Have you stress-tested concurrent writes? There's a free tool where you can post your URL and let people try to find those exact edge cases. Screenshots come in, structured reports. Worth running while you've got PH traffic.
This could be really useful for agencies that build MVPs for clients -- the client keeps editing their product catalog or pricing in Sheets, and the app just reflects it. No more "can you update one field" tickets. How does it handle rate limits or larger sheets with thousands of rows? Any caching layer involved?
This looks really useful! Love how it turns Sheets into an API so quickly. Super practical and clean idea!!
Congrats on the launch 🚀 Smart & scrappy builders have been using google sheets as a flexible db for ages, and you’re bringing it to the masses for this new age!
This is smart. Curious if there's a rate limit on API calls or if it can handle decent traffic on a live site?
Been building with Sheet Ninja for a few weeks now and it's genuinely changed my client projects. Built a full private dental practice dashboard with tons of details all powered by a single Google Sheet with Sheet Ninja. The best advantage is that non-technical business owners can update their own data in a spreadsheet they already know, and see it reflected instantly in a frontend app. Congrats on the launch.
I like about the honesty of the approach. It doesn't pretend to be something crazy. It's just: your data is in a sheet, your app needs that data, here's the bridge.
This looks really useful. I spin up little projects all the time so I’ll definitely give this a try.
Out of curiosity, how does this hold up as projects start to grow? And if something outgrows Sheets, how easy is it to move to something more robust?
Loving seeing this. It's a problem I've had for a while but it always too complex for a non techy to do anything about it... This changes that 👏🏽
Hey Product Hunt 👋,
Really excited to launch Sheet Ninja today - a simple way to use your Google Sheets data in vibe coded apps.
Why we built it
We vibe code apps all the time and love the platforms - Replit, Bolt, Lovable. The most annoying part is making tiny updates - e.g. changing text, updating values, or pulling reports.
You have to dig into the files or prompt the agent to do something that takes two seconds in a spreadsheet. And those agent calls add up.
So we stopped fighting it
Sheet Ninja turns any Google Sheet into a live database by providing a simple, secure API. Paste it with your prompt into whatever builder you're using this month and your AI hooks it up. You just edit a row, the app updates live.
It also means you can move between platforms without loading all your data again. The tools keep changing. The spreadsheet doesn't.
Check out the blog for step-by-step builds — a restaurant menu, a waitlist, a job board, a testimonials page. All vibe coded, all powered by Google Sheets.
Looking forward to seeing all the cool things you'll build.
