Common questions

Is this ClickHouse 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 ClickHouse version runs here?

ClickHouse sandbox for OLAP practice.

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 ClickHouse IDE or playground?

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

What is ClickHouse for?

Fast analytics on large data — OLAP, aggregations, time-series rollups.
