Identifying which InfluxDB product and version you’re using is essential for accessing the correct documentation, troubleshooting issues, and planning upgrades.

#### Identify your InfluxDB version

If you are unsure which InfluxDB product you are using, use our interactive version detector to help identify it:

[Detect my InfluxDB version](#)

## Quick detection methods

### InfluxDB 3 version detection

Check the version using the `influxdb3` command:

```bash
influxdb3 --version
```

Send a `GET` request to the `/ping` endpoint to examine HTTP response headers–for example:

```bash
curl -i http://localhost:8181/ping
```

The response includes version information in the **headers** and **body**:

* **Headers**:

  * `x-influxdb-version`: Version number (for example, 3.9.3)
  * `x-influxdb-build`: `Core`

* **JSON body**: Contains `version`, `revision`, and `process_id`

Example response:

```
HTTP/1.1 200 OK
x-influxdb-build: Core

x-influxdb-version: 3.9.3

{"version":"3.9.3","revision":"abc123def","process_id":"..."}
```

#### SQL version() function

The SQL `version()` function returns the[DataFusion](https://datafusion.apache.org/) query engine version, not the
InfluxDB product version. Use the methods above to identify your InfluxDB
version.

## Understanding InfluxDB products

For a complete comparison of InfluxDB versions and deployment options, see the [InfluxDB platform overview](/platform/).

## Troubleshooting

### Can’t access your InfluxDB instance?

If you can’t directly access your InfluxDB instance:

1. Use the [interactive version detector](#identify-your-influxdb-version) above or [Ask InfluxData AI](#)
2. Answer questions about your setup:
   * License type (paid or free)
   * Hosting model (cloud or self-hosted)
   * Server age
   * Query language preferences

3. Get product recommendations based on your answers

### Still not sure?

If you’re still uncertain, see the [Support and feedback](#bug-reports-and-feedback) options.
