Both of these are platform purchases, so the useful question is which signal each was designed around. New Relic, founded 2008, grew out of application performance monitoring: instrument the app, then get traces, real user monitoring and native synthetic checks from multiple locations in the same product. Splunk, five years older, grew out of log search at scale and added observability later, which is why its own synthetic monitoring reads as bolted on rather than native. The cost models differ too. New Relic meters usage, with a free tier and check allowances that step up through Standard and Pro. Splunk prices Observability Cloud per host across three tiers, from $15/host/mo up to $75/host/mo for the tier that adds browser checks.
Take New Relic if you want application instrumentation and synthetic monitoring from one vendor without an enterprise procurement cycle, and if predictable usage-based billing matters more than raw log firepower. Take Splunk if log volume is the actual constraint, or if security operations and compliance reporting have to share a platform with engineering. Neither is comfortable. New Relic's interface is a lot to take in, costs climb with data volume, and users report alert fatigue. Splunk is expensive at any meaningful scale, needs a dedicated team to set up and tune, and SPL is a language your on-call engineers have to learn before the platform starts paying for itself.

New Relic ships synthetic monitoring in a 100GB/month free tier. Splunk folds SIEM and compliance auditing into the same platform. Pricing inside.
New Relic pricing: 100 GB/mo free data ingest, $0.40/GB beyond. Standard from $10/mo/user, Pro from $349/user/mo. Splunk pricing: Observability Cloud starts at $15/host/mo (Infrastructure tier), rising to $75/host/mo for the End-to-End tier with browser checks. 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 Splunk targets Enterprise SRE, Security Operations, and Platform Engineering. 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 Splunk 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 Splunk directly.
Each tool has its own alternatives page too, not just this matchup.
