Every free tier limits something. Here is what each one limits, from their own pricing pages.

|---|---|---|---|---|---|
| *DockHosting | 500 MB | Never pauses | Never | From $4/mo (Hobby) | Yes, same platform |
| Neon | 1 GB per project | Compute suspends after 5 min idle | Never | Yes | No |
| Supabase | 500 MB | Project pauses after 1 week idle | No (pauses instead) | Yes | No |
| Render | 1 GB | Always on | 30 days, then 14-day grace | Yes | Yes |
Free tiers as published on 1 November 2026: Neon pricing · Supabase pricing · Render free tier docs. Limits change often, so check before you choose. Neon and Supabase are standalone databases; DockHosting and Render also run the app that uses it.
Is it for you
Updated 1 November 2026
The free database is built for one job: give the app you deploy on DockHosting a real PostgreSQL that is always there. Your app reaches it over a private network, so there is no public port to secure and no cold start on the first query of the day.
If you only want a database and your app runs somewhere else, a standalone service like Neon or Supabase fits better on a free plan, because ours only accepts connections from your apps here. From Hobby at $4/mo you can open it to the internet, with daily backups and 2 GB of storage.
Need more than 500 MB, backups or an admin panel? See managed PostgreSQL hosting for every plan's limits.
How to
Create a free account
No credit card. You get 2 projects and 1 database.
Deploy your app
From GitHub or with dock deploy. Node, Python, Go, PHP, Ruby, Java or Docker.
Link a PostgreSQL database
In your project, open Database and press Link a database. Pick PostgreSQL 16, 15 or 14.
Read DATABASE_URL
It's set on your app for you, pointing at the database over the private network.
Connect
Every standard PostgreSQL driver reads a connection URL. Use DATABASE_URL and the same code works locally and here.
Node.js (pg)
import pg from "pg";
const pool = new pg.Pool({ connectionString: process.env.DATABASE_URL });
const { rows } = await pool.query("select now()");Python (psycopg)
import os, psycopg
with psycopg.connect(os.environ["DATABASE_URL"]) as conn:
print(conn.execute("select now()").fetchone())Go (pgx)
conn, err := pgx.Connect(ctx, os.Getenv("DATABASE_URL"))
if err != nil {
log.Fatal(err)
}
defer conn.Close(ctx)Prisma
// schema.prisma
datasource db {
provider = "postgresql"
url = env("DATABASE_URL")
}What the free PostgreSQL database includes, and what it doesn't.
Yes. The Free plan includes one PostgreSQL database with 500 MB of storage. It doesn't pause when idle and doesn't expire, and you don't need a credit card.
