# Webchat v2: Supported Browsers

> View the browsers supported by Cognigy Webchat v2, including Chrome, Firefox, Edge, and Safari, with the minimum required version for each browser.

<Warning>
  As of Cognigy.AI 4.83.0, Webchat v2 is deprecated. Webchat v2 will be retired in February 2026. During this time, only important security updates will be provided for v2, with no further feature additions.
  Before support for Webchat v2 ends, [migrate](https://docs.cognigy.com/webchat/migration/) to Webchat v3.
</Warning>

Cognigy Webchat v2 is compatible with the browsers listed in the table.

| Browser         | Version                                  |
| --------------- | ---------------------------------------- |
| Google Chrome   | 66 or higher                             |
| Mozilla Firefox | 57 or higher                             |
| Microsoft Edge  | 16 or higher                             |
| Safari          | 11.1 or higher<sup>[1](#footnote1)</sup> |

Note that some browsers may not support certain Webchat features.
For example, the **Enable speech-to-text** feature, which adds a microphone button to the Webchat interface, is unavailable in Mozilla Firefox as voice input is not yet implemented in that browser.

***

<sup id="footnote1">1</sup>: Cognigy only supports Websockets on Safari, which means that the fallback to long-polling is not allowed.
