Top Recommended Replacements
SigNoz
FREEBest All-in-One Alternative
Why we like it
The leading open-source alternative to New Relic/Datadog; natively built on OpenTelemetry (OTel); combines Metrics, Traces, and Logs in one beautiful UI; runs on your own cloud (AWS/GCP) so you pay only for storage, not 'ingest markups'.
Keep in mind
Requires self-hosting (ClickHouse backend) unless you pay for their Cloud tier.
Netdata
FREEBest for Real-Time
Why we like it
Unmatched granularity; monitors 2,000+ metrics per server *per second* with zero configuration; instantly detects anomalies; the 'Cloud' dashboard aggregates all your servers for free (freemium model).
Keep in mind
Great for 'Infrastructure' (CPU/RAM) but less powerful than SigNoz for 'Application Tracing' (code-level debugging).
Prometheus + Grafana
FREEBest Industry Standard
Why we like it
The standard cloud-native stack; completely free; massive community support; Grafana allows you to build dashboards that look exactly like New Relic's; no per-user fees ever.
Keep in mind
High maintenance burden; you have to manage the storage and retention yourself.
VictoriaMetrics
FREEBest High Scale
Why we like it
A drop-in replacement for Prometheus that uses 10x less RAM and storage; perfect if you have huge amounts of data that would cost a fortune on New Relic.
Keep in mind
It is a database engine; needs to be paired with Grafana for the UI.
Zabbix
FREEBest for Traditional IT
Why we like it
The 'Old Guard' of monitoring; enterprise-grade and completely free; excellent for monitoring physical hardware (routers, switches, IoT) where New Relic struggles.
Keep in mind
UI feels dated compared to modern tools like SigNoz.
OpenTelemetry (OTel)
FREEBest Strategy
Why we like it
Not a tool, but a standard; by instrumenting your app with OTel instead of the 'New Relic Agent', you can send your data to *any* backend (SigNoz, Honeycomb, Jaeger) instantly, breaking the vendor lock-in forever.
Keep in mind
Requires code changes to implement.
