Self-Hosted Datadog, New Relic Alternatives
6 open-source replacements you can run on your own server — compared on what they are actually good at, not just what they claim.
Updated 2026-10-02
Why people look for a Datadog, New Relic alternative
Datadog and New Relic are superb observability platforms, and they price accordingly — per host, per GB of logs, per custom metric. That model works when the bill is someone else's problem. For a solo developer or a small team, costs scale faster than usage because the pricing is built around enterprise budgets.
6 options, compared
Netdata
Per-second system metrics with zero configuration
Grafana
Dashboards and visualisation for every metric you collect
Prometheus
Metrics collection and alerting built for dynamic infrastructure
SigNoz
Open-source observability platform
Grafana Loki
Log aggregation that indexes labels instead of content
Dozzle
Live Docker container logs in a browser
Which one should you pick?
SigNoz is the strongest open-source equivalent here: traces, metrics and logs in one interface with OpenTelemetry at its core, so instrumenting your apps is vendor-neutral from day one. Budget for the storage — observability data grows quickly, and the reason SaaS pricing feels steep is that the data really is large.
Before you migrate
Self-hosting means you are the one who gets paged when something breaks at 11pm. Before committing, be honest about three things:
- Where will it run? A €4/month VPS handles most of these comfortably. A NAS or spare mini PC is even cheaper if you already own one.
- Who backs it up? A self-hosted service with no backup is worse than a cloud service, because at least the cloud service had someone else's redundancy. Set up automated backups before you migrate real data into it.
- How will you reach it remotely? Most people start with a WireGuard or Tailscale tunnel rather than exposing ports directly. That is the right instinct.
Migrating your data
Nearly every Datadog, New Relic competitor listed above ships an import path — CSV, JSON, or a documented export format. The practical move is to migrate one project or one folder first, run both systems side by side for a week, and only then cut over. Export formats are rarely as clean as the marketing suggests, and it is much easier to notice a broken import on a test set than on five years of records.
