New Relic vs Selenium

A side-by-side comparison of features, pricing, and use cases to help you choose the right tool.

New Relic and Selenium are often evaluated together by teams building out their reliability stack. New Relic (observability platform for every engineer, founded 2008) is typically a fit for Developers, DevOps Teams, and SREs, while Selenium (the battle-tested open-source browser automation framework, founded 2004) leans toward QA Engineers, SDETs, and Enterprise Teams. Both cover 3 of the same core capabilities, so the decision usually comes down to where they diverge.
