About this editor

Write SQL, run against Postgres, read results below.

Exercise SELECTs, JOINs, CTEs, window functions, and CREATE TABLE on real Postgres—not SQLite pretending to be PG. Use it to sanity-check migrations, interview SQL questions, and EXPLAIN plans before you run against staging. Sandbox sessions may reset; save titled snippets for queries you teach or reuse.

Key features

Actual PostgreSQL

Commands run against a sandbox PostgreSQL instance.

Results below the editor

Run a query and read the output in the panel underneath.

Skip local setup

No Docker image, no cloud account, no PostgreSQL install on your machine.

Practice queries

Try CRUD, joins, or shell syntax before an interview or a prod change.

Save examples

Bookmark a useful query by saving it with a title.

Sandbox only

Data can reset between sessions. Not for production workloads.

    Keep a permalink for queries you reuse.

Common questions

Is this PostgreSQL compiler free?

Yes. No payment and no account required for a quick run. Sign in if you want saves tied to your profile.

Do I need to install anything?

No. Code runs on Codeground servers in a sandbox. Just open the page.

What PostgreSQL version runs here?

Postgres in a sandbox.

Can I share my code?

Save with a title to get a permalink, or share the playground URL as-is.

Works for interviews?

Yes. Share a ground link, or use interview mode for a live shared editor.

Multiple files?

This page is for single-file snippets. Use a cloud workspace for full projects.

Will my code still be here tomorrow?

Anonymous sessions can reset. Save with a title (and sign in) for a stable link.

Why use this instead of installing locally?

Good for quick tests, learning, and sharing a snippet. For large offline work, a local IDE still wins.

Is this an online PostgreSQL IDE or playground?

A browser playground with syntax highlighting and one-click Run — run PostgreSQL online without a full local install. Cloud workspaces cover multi-file projects.

Data forever?

Sessions can reset. Not production storage.

Is there a free PostgreSQL playground?

Yes. Run Postgres SQL online for free—no local psql client or Docker required for practice.

Is this a PostgreSQL online IDE?

SQL editor playground with Run and result grids—enough for queries and DDL drills, not pgAdmin replacement.

Can I use PostgreSQL online without installing Postgres?

Yes. Queries hit a sandbox on our servers. Open the page in a browser—no postgres.app or apt install.
