Common questions

Is this DuckDB 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 DuckDB version runs here?

DuckDB CLI in a sandbox for each run.

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 DuckDB IDE or playground?

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

DuckDB vs ClickHouse?

DuckDB is embedded/analytical for local-style SQL. ClickHouse is a server OLAP engine. Both are available as grounds.
