Neon vs Supabase vs Vercel Postgres: Cheapest Serverless Postgres (2026)

The Night I Realized Two of These Were the Same Database

It was late in 2024. I was doing what I always do — starting the rebuild of Clickly for the hundredth time (my URL shortener; I’ve told that whole over-engineering saga in the advanced database guide). New repo, fresh Next.js app, and I went to the Vercel dashboard to click the “Postgres” button like I’d done a dozen times before.

It was gone.

In its place was a “Marketplace.” And the database it was practically shoving in my face, the recommended one, the default? Neon. The exact same Postgres I was already running seven other databases on, for free.

I actually laughed out loud. Because for a year I’d been reading blog posts — the same ten SEO listicles you’ve probably read — solemnly comparing “Neon vs Supabase vs Vercel Postgres” like they were three horses in a race. And I’d just watched one of the horses quietly turn into another horse.

So before we compare anything, let me save you the confusion I had to untangle myself.

Wait — Vercel Postgres Doesn’t Exist Anymore

Here’s the fact nobody updates their blog posts for: Vercel Postgres was killed off.

Vercel shut down its own native Postgres product. Existing databases were automatically migrated to Neon back in December 2024, and the standalone product was fully sunset by June 2025. Today, if you want Postgres on Vercel, you don’t get a “Vercel database” — you open the Vercel Marketplace, pick a provider, and Vercel injects the connection string into your environment variables for you.

And who’s the provider under the hood? Neon. It always was. Vercel Postgres was powered by Neon the entire time — Vercel just slapped their logo on it and resold it. When they decided databases weren’t a business they wanted to run, they stopped pretending and pointed you straight at the source.

So when someone in 2026 says “should I use Vercel Postgres?” the honest answer is: you’d be using Neon, with an extra layer of Vercel billing in the middle. My take? Cut out the middleman. Go to Neon directly. Same database, and you’re not tied to Vercel’s dashboard for something that has nothing to do with your frontend.

The “three-way comparison” is really a two-way comparison wearing a trench coat. It’s Neon vs Supabase. That’s the real fight.

You can still provision Supabase through that same Vercel Marketplace, by the way. So even Vercel agrees the choice that matters is Neon or Supabase.

The Free Tiers, Side by Side

This is where the broke solopreneur lives — the free tier. If you’re making $0 MRR (and if you’ve read the survival guide, you know I spent months paying roughly $90/month for products nobody used), the free tier isn’t a “trial.” It’s your entire infrastructure budget. So it has to actually work.

Here’s what each one gives you as of 2026, straight from their pricing pages:

	Neon (Free)	Supabase (Free)
Storage	0.5 GB per project	500 MB database
Projects	Up to 100	2 active
Compute	100 CU-hours/mo, autoscale to 2 CU	Shared, capped
Idle behavior	Scale-to-zero after 5 min	Pauses after 7 days
Extras	Postgres + branching + Neon Auth	Postgres + auth + storage + realtime + edge functions
Credit card	Not required	Not required

Both are genuinely free. Both are real Postgres — Supabase is Postgres, it just wraps a whole platform around it. But look at that “idle behavior” row, because that single line is the difference between a free tier that helps you and one that quietly embarrasses you. (I pulled Supabase’s free plan apart in its own Supabase free tier guide — the 7-day pause and every other limit.)

The One That Actually Bites: Scale-to-Zero vs “Pause”

This is the thing the listicles gloss over, and it’s the thing that actually matters when you have zero users.

Neon scales to zero. After five minutes of no queries, your compute spins down and you stop being billed for it. The instant a request comes in, it wakes back up. There’s a cold-start delay of a few hundred milliseconds — noticeable if you’re staring at it, invisible to a real user. The database is always reachable. It never goes offline. It just gets cheap when nobody’s looking.

Supabase pauses. On the free tier, if your project gets no requests for seven days, Supabase pauses the entire project. Not scales down — pauses. It becomes unreachable until you log into the dashboard and click “restore.” One click, sure. But here’s the scenario that burned me on a side project: you build something, you share the link on Reddit, nothing happens, you move on. Three weeks later someone actually finds it, clicks through, and gets… a dead app. Because the database went to sleep and never woke up on its own. Your one shot at a first impression, gone, because you didn’t babysit a dashboard.

For a solopreneur running a dozen tiny experiments — exactly what I do — that’s a dealbreaker. This is the whole reason I have (last I counted) seven Postgres databases sitting on Neon’s free tier, each its own project, each costing me nothing, none of them ever going dark. On Supabase I’d be capped at two active projects and playing whack-a-mole with the pause button.

The Hard Truth: Supabase’s free tier is designed to nudge you toward the $25/month Pro plan the moment you’re serious. Which is fair — they’re a business. But “serious” and “can afford $25/month” are not the same milestone when you’re at $0.

Pricing When You Actually Scale

Say the dream comes true and you get traffic. What happens to the bill?

Neon is pure usage-based, and this is where they got genuinely aggressive after the acquisition. Compute on the Launch plan is $0.106 per CU-hour, storage is a flat $0.35 per GB-month, and — this is the part I love — there’s no monthly minimum anymore. They removed it. You pay for exactly what you burn. A quiet database that scales to zero all night costs you cents. If your invoice comes out under fifty cents, they don’t even bother collecting it.

That flat $0.35/GB storage is worth pausing on. Neon used to charge $1.75/GB. After Databricks bought them (~$1 billion, May 2025 — yes, Neon is a Databricks company now), they cut storage by 80% and dropped compute prices across the board. Getting acquired by a giant usually means prices go up. Neon’s went down. I’m not complaining.

Supabase works differently: it’s a flat $25/month for the Pro plan, which bundles $10 of compute credit, 8 GB of database, 100 GB of file storage, and 100K monthly active users, with usage-based overages above that. No auto-pause. Predictable. If you like knowing your number in advance, $25 flat is comforting.

But run the math for a small SaaS. On Neon, a real-but-modest app might cost you a few dollars a month — genuinely, single digits — because you’re billed on actual compute and your database is asleep most of the time. On Supabase you’re at $25 the moment you leave the free tier, whether you’re using it or not. For me, the paranoid Indian engineer who counts paisa, that gap matters. (I broke my whole monthly stack down, line by line, in what it really costs to run a SaaS — the database is one of the smallest lines on it, and this is why.)

It’s Not Really About Price. It’s About What You’re Buying.

Here’s the honest reframe, and it took me too long to get here: Neon and Supabase are not the same kind of product, even though they’re both “serverless Postgres.”

Neon is a database. That’s it, and I mean that as a compliment. It’s PostgreSQL, done beautifully, with serverless superpowers — autoscaling, scale-to-zero, and its killer feature, branching: you can spin up a full copy of your database the way you’d git checkout a branch, test a migration on it, and throw it away. For an engineer who wants to assemble his own stack — bring my own auth, my own storage on Bunny, my own everything — Neon is exactly the right amount of opinionated. Nothing I didn’t ask for.

Supabase is a platform. It’s the open-source Firebase alternative. You get Postgres, yes, but also authentication, file storage, realtime subscriptions, edge functions, and auto-generated APIs — all wired together, all from one dashboard. If you’re not an engineer, or you just want to ship the thing this weekend and not stitch six services together, Supabase is a genuinely great deal. One tool, batteries included, and it’s built on standard Postgres so you’re not trapped in a proprietary corner the way you’d be with Firebase. (That exact trade-off is the whole Firebase vs Supabase fight, if you’re choosing between the two.)

So the question was never “which is cheaper.” At the scale you and I operate, both are close enough to free that it’s noise. The real question is: do you want a database, or do you want a backend?

• Want to control every piece and keep your bill microscopic? Neon.
• Want auth, storage, and realtime handed to you so you can focus on the product? Supabase.

Neither is wrong. I’ve recommended Supabase to non-technical friends without a second thought. I just don’t personally use it, because I’m the kind of person who’d rather wire up Prisma against a raw Postgres and know exactly what every moving part does. That’s a personality flaw, not a technical verdict.

So Which One Do I Actually Use

Neon. Every time. Seven databases, free tier, been there for years.

But that’s my answer, shaped by my biases: I’m an engineer first, I over-optimize compulsively, I already have a stack I love, and I flinch at any flat fee I’m not fully using. Neon’s scale-to-zero and no-minimum billing are tailor-made for someone running a graveyard of half-finished experiments.

If you’re not that person — if you want to log into one dashboard and have auth, a database, file uploads, and realtime all just work — Supabase will get you shipping faster, and $25/month is nothing once you have even a handful of paying users.

And “Vercel Postgres”? Forget it exists. It doesn’t, not really. If a tutorial tells you to use it, that tutorial is stale. Go to Neon directly and skip the middleman. (Curious about the other 1% of cases where you’d reach past plain Postgres entirely — Turso, ClickHouse, per-user SQLite? That rabbit hole is the advanced database guide.)

The whole point of writing this out isn’t to crown a winner. It’s so you don’t do what I did — spend a weekend “researching” a three-way battle where one contestant had already quietly left the building. Know what the tools actually are, pick the one that fits how you build, and get back to the only thing that matters: shipping something and finding someone to use it.

Your database is not your bottleneck. It never was.

This is the Broken Engineer Guide — I over-engineer everything, fail at business, and hand you the receipts so you don’t have to bleed for the same lessons. Now go build something, and let the database scale itself to zero while you sleep.
