This is really helpful thanks. I've just pushed a build to disable the scroll-jacking - ETA 5-10 mins!

Hi all - a friend and I have been dabbling in the entrepreneur space for years, but we never really pulled the trigger because of our corporate jobs. We suffer from the same thing that plagues a lot of engineers: we know how to build products, but we are weak at distribution and marketing.
We feel that being able to build is becoming table stakes and the ability to actually get a product into people's hands is more important than ever. We built SheetNinja (https://sheetninja.io) to force ourselves to learn that side of the business from the ground up.
We chose a validated market (sheets-to-api) so we could focus on the "how to find users" problem rather than wondering if the category was useful. It also fits our current "vibe coding" workflow i.e. when we use LLMs or Replit to spin up an idea, a Google Sheet is often the fastest way to handle CRUD without the friction of setting up a traditional database.
We are looking for feedback on the tool itself and the landing page. We have a lot of visitors but a lower sign-up rate atm.
Please share the repo for the API and we will happily provide technical feedback.
saadn92•Mar 29, 2026
The "we chose a validated market so we could focus on learning distribution" framing is really smart and honestly something I wish I'd done earlier. I'm building a workspace/collaboration tool and spent way too long on the product side before realizing the distribution muscle is a completely separate skill that doesn't develop on its own.
One thing I've noticed from the sheets-as-backend pattern: the reason people
keep reaching for spreadsheets is because the editing UX is instant and familiar.Any tool that wants to replace this for non-technical users needs to nail that "just click a cell and type" experience. That's the hard part honestly.
Imustaskforhelp•Mar 29, 2026
Good project but I wish something like this can exist for proton mail, I have made some puppeteer scripts which can hook up to proton docs.
But Proton is really doing some great disservice to not having a public api for their docs.
I can imagine it being used for anonymous comments page for webpages etc.
I am not sure if there is something that you can do about it though given that the fundamental issue of this is caused by proton not having an api whereas I think google docs does have API.
It's more a message to proton if anything.
PullJosh•Mar 29, 2026
Looks great! I’ve definitely wanted this exact thing before. I will consider reaching for this next time I need to throw together a quick app.
mememememememo•Mar 29, 2026
Oh man fix the site. If I scroll down it auto scrolls up after 2 seconds. And other bugs.
sxa001•Mar 29, 2026
Sorry about that - I've pushed a fix to stop it from auto-scrolling which should be propagating through soon. Thank you for flagging this
mememememememo•Mar 29, 2026
Thanks! No need to be sorry :)
tyleo•Mar 29, 2026
This site is pretty broken. The project seems cool but I’d recommend a more static landing page. I bounced very quickly. Didn’t even make it to the bottom with all the distracting animations.
Don’t really get the purpose for this apart from throw away projects.
For vibe coders is it really “hours” setting up a database these days? GCP cloud sql + drizzle ORM is minutes and actually scales unlike a spreadsheet, heck Claude can even write you a deployment script and run it over GCP CLI.
misiek08•Mar 29, 2026
Cloud SQL costs gazillions, sheet is free (other than selling your data)
codybontecou•Mar 29, 2026
Most are lucky to get a few sign ups.
robotswantdata•Mar 29, 2026
Cloud sql lowest tier is pennies a day, this ninja platform is also not free.
A spreadsheet is a misclick away from corruption, why not spend another prompt on getting Claude to configure a db?
kevcampb•Mar 29, 2026
Which works out at $100 USD / year. You might think that's trivial, but when you start provisioning multiple environments over multiple projects it starts to add up.
It's a shame that Google haven't managed to come up with a scale to zero option or serverless alternative that's compatible.
rvz•Mar 29, 2026
It is trivial to set up a database on GCP given that you know what you are doing and I would pay Google for that stability and support for setting up multi-tenancy and region.
Using Google spreadsheets as a backend will just cause them to charge everyone later.
Sheet Ninja isn't free. Even on their side, "free" does not mean what you think it means.
robotswantdata•Mar 29, 2026
setup a DB project , use same cloud sql instance for all DBs. Did that for years on non prod or experimental projects.
$100 is a bargain for what you get in terms of resiliency
Yokohiii•Mar 29, 2026
Sheet Ninja is 108 USD / year and has tiny capacities for every metric. SQLite is free and would stomp this in every aspect on low budget hosting. Even a tiny API that stores CSV would be magnitudes more efficient.
But what would scare me the most, is that google can easily shut this thing down.
n_e•Mar 29, 2026
> Cloud sql lowest tier is pennies a day
Unless things have improved it's also hideously slow, like trivial queries on a small table taking tens of milliseconds. Though I guess that if the alternative is google sheets that's not really a concern.
gruez•Mar 29, 2026
>sheet is free (other than selling your data)
Except the sheets-to-api SaaS charges $9/month if you want more than 250 requests.
bercini•Mar 29, 2026
You can fire up a burstable postgres for about $20/mo
lelanthran•Mar 29, 2026
> Cloud SQL costs gazillions,
WTF is "Cloud SQL"?
I have a postgresql server running on a $5/m VPS that I add DBs to as and when I explore some new idea.
Zetaphor•Mar 29, 2026
SQLite is enough for 98% of all of these use cases, and 100% of the ones this would appeal to
faangguyindia•Mar 29, 2026
Don't do this guy, cloudsql costs a lot.
rsafaya•Mar 29, 2026
Really good project for a quick data back end.
One feature suggestion: webhook support for row changes:
If my Sheet updates (say, a new waitlist signup), I'd want to trigger for e.g. a Slack notification. Supabase has something similar with their database webhooks. I use that extensively for kicking off signup workflows.
snoopen•Mar 29, 2026
You can do this now directly in the Google environment. Should be trivial to vibe code Google Apps Script to hit a Slack endpoint. You'd probably use an 'on edit' trigger to run the code.
sxa001•Mar 29, 2026
That's a great suggestion, thank you
For your signup workflows, how sensitive would you be to latency? Would a 30 to 60 second delay be a dealbreaker, or are you looking for something that hits Slack the instant the row is created?
(The challenge with Google Sheets is we'd have to poll for changes)
smrtinsert•Mar 29, 2026
Do vibe coders need an api for an api? Sounds like something solvable with a skill
igor_mart•Mar 29, 2026
Just impossible to read the landing page on mobile due to endless carousel sliding which constantly returns you to the top of the page
michaelcampbell•Mar 29, 2026
I didn't have any "top of page" navigations that I didn't control going on.
odest•Mar 29, 2026
I really like the idea of using Google Sheets for quick prototyping and maybe "vibe coding" without the friction of setting up a traditional DB.
I haven’t noticed a scrolling issues, btw
lpcvoid•Mar 29, 2026
The world needs less vibe coded slop, not more
evanbabaallos•Mar 29, 2026
Is this meant to replace databases?
_joel•Mar 29, 2026
"Ship now, pay later" you're not wrong.
0xbrad•Mar 29, 2026
Awesome！
curbits•Mar 29, 2026
I have done this for my own projects for years it’s great for projects that are only for me and gives me a very good db editor also. Cool project though the only risk I see is that if the target audience are vibe coders they will you known just vibe code an integration
sxa001•Mar 29, 2026
Thank you! The idea of our target audience just vibe coding this themselves definitely gave us pause for thought while we were building it :)
We're thinking of playing around with the pricing right now to make sure it is cheaper to just use this than to spend the time and tokens recreating the logic. We will see how it plays out.
pduggishetti•Mar 29, 2026
SQLite, SQLite + drizzle with WAL mode, push it to a VPS, do not waste your time on anything else :)
Thank me when things become super easy!
When things scale, SQLite will still be fine, will fit 99% of the vibe coders needs!
When they don't then migrate to what ever!
mettamage•Mar 29, 2026
This requires technical skill
threatofrain•Mar 29, 2026
If Claude can do it reasonably well then there’s another tier of technical skill that can reach.
rvz•Mar 29, 2026
> When things scale, SQLite will still be fine, will fit 99% of the vibe coders needs!
No it won't. SQLite is a poor choice at handling this, period. With all those hacks it still doesn't make any sense over something like PostgresSQL which is designed for that use case.
Yet another reason why I dismiss this nonsense of vibe coding.
pduggishetti•Mar 29, 2026
I accept what you say, my point is for 99% of vibe coded and vibe coders stuff you have no reason to spin up anything more than sqlite, if you grow migrate to postgres, you will have drizzle help you!
A single vps like 1-2 GB ram and 2 CPU can suffice 100s of your projects
SQLite can handle 100s of users easyily
And 99% of vibe coded projects won't grow further than 100s of concurrent users
Raed667•Mar 29, 2026
I put Google Sheets as a backend (in production) when i wanted a select non technical people to be able to see and modify the data without the cost of building a backend.
I really wish auth was easier to setup for services though, i see no reason google can't provide this out of the box
riffraff•Mar 29, 2026
You can auth with Google auth after you configure an app, what are you thinking of that would be simpler?
Raed667•Mar 29, 2026
I meant to authenticate a service (that is not running on GCP) to access the sheet, it requires a service account and felt more convoluted than what it needs to be
afferi300rina•Mar 29, 2026
Completely agree. Managing service account JSON keys and configuring IAM roles just to access a single sheet feels like a huge overhead for simple projects.
_pdp_•Mar 29, 2026
If this site does not run on top of a google sheet then don't believe it.
xnx•Mar 29, 2026
A pay option like this definitely seems worse than the Firebase backend that AI Studio would automatically use.
I like this idea, I wrote a tiny CRM-like thing for my mom a month or so ago (upgrade from a google sheet that I had previously upgraded from an Apple Note) and it uses Sheets as it's backend. She can always go back to the Sheet and lose nothing but the web interface she uses it tailored to exactly what she needs. I couldn't be happier with it and she loves it.
I'll have to remember this for my next little one-off tool.
kent8192•Mar 29, 2026
I think it can be one option to achieve a tiny goal.
Some companies often think that using AWS or GCP is too much of a stretch for a minimum target.
So, it can be a good way to meet their request.
pezo1919•Mar 29, 2026
Afaik Google Sheets comes with REST API endpoints by default.
How is this different?
Which scenarios do and which DO NOT require Sheet Ninja?
NicoJuicy•Mar 29, 2026
Did this 9 years ago :o, cached it though.
zephyrwhimsy•Mar 29, 2026
Version-controllable, plaintext knowledge bases have a durability advantage that no SaaS tool can match. Your notes will outlive any company.
mamday1•Mar 29, 2026
You do not need to go through these guys Google provides access to the URL to use the sheet as a database and also allows you to deploy Javascript and even host the site with AppScript (example https://script.google.com/macros/s/AKfycbzYt_aXBdQlnMM7idlVD... )
sroerick•Mar 29, 2026
This is a great project, very cool, but it is actually insane to me that CRUD is so apparently hard that Google Sheets is the best solution
ugh123•Mar 29, 2026

Andrex•Mar 29, 2026
The attractiveness of a spreadsheet comes in the display and the charts, etc.
For a serious database doing actual transactions, I'm not sure about the utility.
aitchnyu•Mar 29, 2026
Umm, does Google sheets let you fetch rows in O(log(n)) time or aggregate numbers?
Andrew_McCarron•Mar 29, 2026
Nice execution on the Google Sheets as backend angle — it's a much lower friction onboarding story than "set up a database." How are you handling concurrent writes when multiple users edit the sheet at the same time?
sxa001•Mar 29, 2026
Thanks and great question - appends are atomic via Google's Sheet API, but updates/deletes are currently positional based on row ID. It's 'last-write-wins' for now if there are multiple concurrent updates.

You can publish any publicly readable sheet/form (append rows with publicly available form):
- sample sheet: https://veneer.leftium.com/s.1RoVLit_cAJPZBeFYzSwHc7vADV_fYL...
