# ClickHouse playground

[ClickHouse Playground](https://sql.clickhouse.com) allows people to experiment with ClickHouse by running queries instantly, without setting up their server or cluster.
Several example datasets are available in Playground.

You can make queries to Playground using any HTTP client, for example [curl](https://curl.haxx.se) or [wget](https://www.gnu.org/software/wget/), or set up a connection using [JDBC](/integrations/language-clients/java/jdbc) or [ODBC](/concepts/features/interfaces/odbc) drivers. More information about software products that support ClickHouse is available [here](/integrations/home).

  Credentials

| Parameter | Value |
| :- | :- |
| HTTPS endpoint | `https://play.clickhouse.com:443/` |
| Native TCP endpoint | `play.clickhouse.com:9440` |
| User | `explorer` or `play` |
| Password | (empty) |

<h2 id="limitations">
  Limitations
</h2>

The queries are executed as a read-only user, so the following limitations apply:

* DDL queries aren't allowed
* INSERT queries aren't allowed

The service also has quotas on its usage.

To avoid the read-only limitations and experiment with loading your own data, you can sign up for a free [ClickHouse Cloud trial](https://clickhouse.cloud/signUp?loc=docs-get-started-sample-datasets-playground) or [install ClickHouse](/get-started/setup/install) locally.

HTTPS endpoint example with `curl`:

```bash theme={null}
curl "https://play.clickhouse.com/?user=explorer" --data-binary "SELECT 'Play ClickHouse'"
```

TCP endpoint example with [ClickHouse client](/concepts/features/interfaces/client):

```bash theme={null}
clickhouse client --secure --host play.clickhouse.com --user explorer
```
