Download

Download from the right side or visit the release page. Expand 【Assets】and choose the version suitable for your platform, supporting Windows, macOS, Linux.

Important Notes:

1. Before using, ensure that the advertised.listeners setting of your Kafka cluster is correctly configured. If not configured or if domain names are used, add corresponding domain name resolution entries in the hosts file of your local machine to avoid connection issues due to unresolved domain names, even when IP addresses are entered in King.
2. If your connection requires SSL, enable TLS and ignore verification unless you have a certificate, in which case enable TLS verification and provide the certificate path.
3. SASL users should enable SASL and select the appropriate SASL protocol (usually plain), then enter the username and password.
4. In case of webview2 runtime errors, download and reinstall the runtime from Microsoft's official website: https://developer.microsoft.com/en-us/microsoft-edge/webview2
