Free PostgreSQL Playground

The PostgreSQL Playground is a free online PostgreSQL database that runs directly in your browser. There's nothing to install, no account to create, and no server to provision - open the page, paste in SQL, and start running queries against a real PostgreSQL instance within seconds.

Because the Playground runs in your browser, every session is private and isolated. Your queries, tables, and data exist only in your local browser memory and disappear when you close the tab. That makes it safe to experiment with PostgreSQL features, test SQL snippets before running them against production, learn PostgreSQL hands-on, reproduce bugs in a reproducible environment, or share self-contained examples with colleagues without needing shared infrastructure.

The Playground is useful for developers, data analysts, students, technical writers building tutorials, and anyone who needs a quick, throwaway PostgreSQL environment.

Data in the Postgres Playground is temporary. It is stored only in your browser’s memory and will disappear when you close or refresh the browser. It is not saved to disk or stored in browser local storage.

To save your work, copy your SQL into a local file or version control before closing the tab. If you need a persistent PostgreSQL instance, you can spin one up on Aiven's free Developer Tier.

Yes. The PostgreSQL Playground runs PostgreSQL directly in your browser using WebAssembly, so your queries and data never leave your device. We don't store your SQL code, query results, or any datasets you create.

Your privacy is our priority. We collect minimal, anonymized data to enhance the tool’s performance and user experience. This data includes:

• The length of your SQL query.
• Whether the query executed successfully.
• Internal error messages (only in rare cases for troubleshooting).

These internal error logs do not include your original SQL code or syntax errors you see in the tool. Additionally, this data is not shared with third parties.

You can run almost any standard PostgreSQL command in the Playground: create tables, insert data, run SELECT queries, define views, build indexes, write CTEs and window functions, test PL/pgSQL functions, and experiment with PostgreSQL-specific features like JSONB, arrays, and full-text search. It's ideal for learning, testing snippets, reproducing bugs, or sharing reproducible examples with colleagues.

The Playground runs a recent stable version of PostgreSQL. Most features from modern PostgreSQL releases are supported, but some advanced extensions or features that require server-level configuration may not be available.

Yes. Because the Playground runs in your browser, it has a smaller memory footprint than a production database and isn't suited for large datasets or long-running workloads. Some extensions, replication features, server configuration changes, and external integrations aren't available. For full PostgreSQL functionality, use a managed instance such as Aiven for PostgreSQL.

Yes. You can paste any SQL script - including CREATE TABLE statements and INSERT data - directly into the editor and run it to set up your schema. For larger datasets, consider seeding only a representative sample rather than full production data.

Yes, the Playground is completely free and requires no signup. Use it as often as you'd like for learning, testing, or sharing examples.

The Playground doesn't currently support shareable session links. To share your work, copy your SQL code into a message, gist, or document. Others can paste it into their own Playground to reproduce your results.

Alongside the PostgreSQL Playground, Aiven offers a SQL Syntax Checker, SQL Optimizer, SQL Formatter, a SQL Compare tool, and a Text-to-SQL AI Converter. All are free and require no signup.

Once you've experimented in the Playground, check out the rest of Aiven's free developer tools to validate, format, and optimize your queries.

Run the SQL command SELECT * FROM pg_available_extensions; in the Playground and it will report what extensions are included.

At the moment, this includes pgvector (the vector extension) and the PL/pgSQL procedural language (plpgsql). You can enable them with CREATE EXTENSION IF NOT EXISTS vector; (for pgvector) and CREATE EXTENSION IF NOT EXISTS plpgsql; (for PL/pgSQL).
