Neon vs Supabase in 2026 (and the third option neither of them is)

The usual framing of this comparison is "which managed Postgres is better," and that framing is why the arguments never resolve. Neon sells Postgres as a resource that scales and suspends. Supabase sells a backend, and Postgres is the part of it you happen to write SQL against. Both statements are compliments. They just mean the two products lose to each other on different days.

Everything below is from the vendors' own docs and pricing pages, checked in July 2026. Where I state a negative, it is a negative about that vendor's published capabilities, nothing broader.

The rows

Now the parts that a table cannot hold.

Branching: same word, different products

This is the row where the vendors are furthest apart while appearing closest.

Neon's branching is copy-on-write at the storage layer. A branch is nearly instant and initially nearly free in space, because it shares pages with its parent until something diverges. The Free plan includes 10 branches per project, and past that you pay $1.50 per branch-month. The mental model is git for your data, and it holds up better than most database metaphors do.

Supabase's branching is tied to your git workflow: a preview branch is created for a pull request, with persistent branches available for longer-lived environments. It is arguably more integrated, because the branch is an environment rather than only a database. But branch compute is billed separately, starting at $0.01344 per hour, and the detail worth circling in red is in their own usage docs: branches are not covered by the spend cap.

Read that once more if you use the spend cap as your safety net. A spend cap that excludes the feature most likely to be created programmatically by CI is a safety net with the interesting part cut out. If you open a lot of PRs, price the branches deliberately rather than assuming the cap catches them.

The free tiers fail in different directions

Neon's free plan gives you 100 CU-hours of compute, 0.5 GB of storage and 5 GB of transfer per project per month. Exceed them and compute suspends, and their docs are explicit that none of these limits delete your data. It is a small tier that fails soft.

Supabase's free plan is 500 MB and, more importantly, projects are paused after one week of inactivity. Paused projects are restorable for 90 days, after which you can download a backup but not resume the project. The size is not what bites people. The pause is, because Supabase projects are not just databases: pause one and the Auth API and PostgREST endpoint go with it, which means a demo app you show someone once a month is broken every time you open it.

So: Neon's free tier degrades on volume, Supabase's degrades on time. Which one hurts depends on whether your side project is busy or dormant.

Pricing shape is the real decision

Neon is usage-metered with no minimum: $0.106 to $0.222 per compute-hour, $0.35 per GB-month of storage, $0.10 per GB of egress. If your workload is spiky and idle-heavy, this is genuinely the cheapest structure in the category, because suspended compute is not billed compute.

Supabase is a flat base plus meters. Pro is a $25 base, Team is $599, and on top of the base you meter compute, storage, egress, and monthly active users. The base buys you the bundle, and the bundle is the reason to be there.

Neither of these is a rip-off. Both are unpredictable in the same specific way: you cannot answer "what is next month" without predicting your own traffic. If that unpredictability is what sent you searching, note that swapping one meter for a different meter does not fix it, and quite a lot of "we moved from X to Y" posts are exactly that swap.

The rows procurement asks about

Two rows nobody cares about until someone in a compliance review does.

IP allowlisting. Neon has IP Allow, which is project-wide (optionally narrowed to protected branches) and is a Scale plan feature, so the small team that wants network restriction has to buy several tiers up to get it. Supabase has network restrictions at project scope, and their docs are refreshingly blunt that the restrictions do not apply to HTTPS APIs such as PostgREST, Storage, and Auth, or to the Supabase client libraries. If your threat model is "only our VPC can reach the data," an allowlist that exempts the auto-generated REST API is a partial answer and needs to be understood as one.

Client certificates. Neither documents mTLS. Neon's connection-security page enumerates require, verify-ca, verify-full and channel binding with SCRAM-SHA-256-PLUS, and no client certificate appears anywhere on it. Supabase's SSL enforcement doc covers server-side modes and downloading their CA so you can do verify-full. Both are about you validating the server, which is not the same thing as the server validating you. That is a per-vendor observation from two specific doc pages and I am not claiming anything about the wider market.

Self-hosting

Supabase publishes a real Docker Compose stack of the whole platform, with a stated floor of 4 GB of RAM, 2 cores and 40 GB of SSD, plus a reverse proxy you configure for HTTPS. It is a production posture, not a dev companion, and running it is a decision with an owner.

Neon's storage engine is Apache-2.0 and the README says it can be run on a workstation for small experiments. There is no packaged production self-host product, so the honest cell is "source only" rather than "no."

So which one

Skipping the hedging:

• Pick Supabase if you want auth, storage, realtime, and a REST layer without assembling them. That bundle is the product, and no comparison table row changes it. If Supabase Auth is working for you, the migration math almost never favors leaving.
• Pick Neon if you want plain Postgres with the best branching story in the category and a bill that goes to nearly nothing when you are idle. It is a better database product; Supabase is a better backend product.
• Pick neither if what is actually bothering you is that you are about to need a second kind of database.

That last case is the one this comparison cannot resolve, because Neon and Supabase agree on the constraint that causes it.

The third option, and what it is not

I build Layerbase Cloud, so weigh this accordingly. It is not a better Neon or a cheaper Supabase. It is a different shape: 18 database engines behind one account and one flat bill, so the Postgres, the cache, the vector store, and the search index stop being four vendors. Free is $0 for 2 databases and 5 GB with no card, Solo is $5/month, Pro is $15/month, and there is no meter on queries, connections, or egress on any plan. Branching runs on 9 of the engines rather than only Postgres, the HTTP query API covers 17 of them, mTLS with a per-database CA is available on Pro, and the IP allowlist is per database on every plan including Free.

Where the honest losses are, since a comparison post that wins every row is an ad:

• Neon's Postgres branching is better than ours at Postgres specifically. Copy-on-write at the storage layer beats a full copy on space and speed, and if per-PR branching of one large Postgres is your central workflow, that is a real reason to stay.
• We do not replace the Supabase bundle. No hosted auth service, no object storage, no realtime subscriptions, no edge functions. We manage a database and give you a console over it; the login flow stays in your app.
• No auto-generated REST layer. PostgREST turning a schema into an API is a genuinely nice trick. Our HTTP query API is a query endpoint, not a generated resource API.
• Single region. If you need geo-distributed reads, look elsewhere.
• Free databases sleep. An hour idle hibernates and wakes on the next connection in about one to five seconds. Fourteen idle days archives, and restoring is an explicit click. The difference from a paused Supabase project is that nothing else in your stack goes down with it, because there is no Auth API attached.

If you are weighing a move off either one, I wrote the Supabase side in more depth in Supabase alternatives, including what you lose leaving Supabase Auth, and the Neon ownership question in Neon is now a Databricks product. The mechanics live at layerbase.com/migrate/neon and layerbase.com/migrate/supabase, both of which copy the database across for you.

And if the answer is that your current vendor is fine, that is a completely legitimate outcome of reading a comparison post. The bad outcome is migrating for a row you do not actually use.
