Mabl and Selenium are often evaluated together by teams building out their reliability stack. Mabl (intelligent test automation platform for qa teams, founded 2017) is typically a fit for QA Engineers, SDET, and QA Managers, while Selenium (the battle-tested open-source browser automation framework, founded 2004) leans toward QA Engineers, SDETs, and Enterprise Teams. Both cover 2 of the same core capabilities, so the decision usually comes down to where they diverge.
