Splunk RUM Agent supports all the modern browsers. The support is available for the following browser families that embed support for ES6 and ResourceTiming API:
| Browser family | Versions supported | Comments |
|---|---|---|
| Chrome & Chrome Android | 51+ | |
| Safari & Safari iOS | 10.1+ | Initial page load spans are not linked with server-side spans, as Safari does not support server-timing header. In addition, Safari 10.1 is missing resourceFetch spans. |
| Firefox | 36+ | |
| Edge | 12+ | |
| Internet Explorer | 11 | Requires a different build of the Browser Agent, available under release assets as splunk-otel-web-legacy.js. Due to the extra size (+40Kb) required, the IE support is not distributed in the standard bundle |
