# ClickHouse Playground {#clickhouse-playground}

[ClickHouse Playground](https://play.clickhouse.tech?file=welcome) allows people to experiment with ClickHouse by running queries instantly, without setting up their own server or cluster.
Several example datasets are available in Playground as well as sample queries that show ClickHouse features.

The queries are executed as read-only user. This implies some limitations:

-   DDL queries are not allowed
-   INSERT queries are not allowed

The following settings are also enforced:
- [`max_result_bytes=10485760`](../operations/settings/query_complexity/#max-result-bytes)
- [`max_result_rows=2000`](../operations/settings/query_complexity/#setting-max_result_rows)
- [`result_overflow_mode=break`](../operations/settings/query_complexity/#result-overflow-mode)
- [`max_execution_time=60000`](../operations/settings/query_complexity/#max-execution-time)
