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.
On capability breadth, New Relic pulls ahead here: it uniquely offers Synthetic Monitoring, Real User Monitoring, AI-Powered, and Uptime Monitoring, among others. Choose New Relic if those matter to your workflow; Selenium (Free and open source) remains a solid option if Open Source and On-Premise / Self-Host is what you need.

New Relic is observability platform for every engineer, while Selenium is the battle-tested open-source browser automation framework. New Relic adds Synthetic Monitoring, Real User Monitoring, and AI-Powered on top of the shared feature set. Selenium brings Open Source and On-Premise / Self-Host that New Relic does not.
New Relic pricing: Usage-based limits: Free (500 checks/mo), Standard (10k checks), Pro (1M checks). Selenium pricing: Free and open source. Evaluate against your check volume and team size; entry pricing rarely reflects total cost at scale.
New Relic is designed with Developers, DevOps Teams, and SREs in mind, whereas Selenium targets QA Engineers, SDETs, and Enterprise Teams. If your team matches the former profile, New Relic is usually the closer fit.
ObserveOne combines synthetic monitoring with AI browser checks that adapt as your UI changes. It offers a free tier, so you can benchmark it against New Relic and Selenium directly.
ObserveOne combines AI browser checks with uptime, API, and SSL monitoring on per-run pricing. The free tier is enough to benchmark it against New Relic and Selenium directly.
Each tool has its own alternatives page too, not just this matchup.
