SigNoz is an OpenTelemetry-native observability platform for APM, logs, traces, metrics, exceptions and alerts. Its listed starting price is $49, with a free plan; teams can also self-host it. Developers weighing a replacement should compare telemetry compatibility, costs as usage grows, and who operates the monitoring stack. The alternatives below range from free, self-managed metrics monitoring to hosted observability platforms. Before migrating, check each vendor’s current SDK support, ingestion options, pricing units and data-export paths.
01Why people leave SigNoz
SSO may require a paid plan
A self-hosting Reddit commenter said SSO/OIDC was behind a price wall in the version they discussed; verify current edition limits.
Long-term pricing is a concern
A Reddit thread questioned how SigNoz’s business model could affect customers over time; compare current rates and usage controls.
Self-hosting means operating the stack
Teams that want less infrastructure work may prefer a hosted service; SigNoz offers both cloud and self-hosting options.
02The alternatives, ranked by fit
- OpenTelemetry and Prometheus
GrafanaGrafanaGrafana Cloud is a fit for teams already using OpenTelemetry or Prometheus, and its listed entry point is $19 with a free plan. The pricing summary warns that costs rise with telemetry usage, so model expected ingest before moving data. Confirm the current SDKs, ingestion interfaces and export path for your services before planning a migration.
Trade-off: Telemetry costs can rise with usage; check current rates before committing.

$19/mofree plan - Self-managed metrics
PrometheusPrometheusPrometheus is a free option for teams running their own monitoring, with PromQL-based metrics and alerting. It can suit developers who want control over the metrics stack rather than a hosted observability bill. The change is operational: you run and scale the servers yourself. Check how your existing traces, logs and alert workflows will be handled before replacing SigNoz.
Trade-off: You operate and scale the servers; the listed fit is metrics and alerting.

Freefree plan - Hosted OpenTelemetry
New RelicNew RelicNew Relic targets teams consolidating observability signals and using OpenTelemetry-first instrumentation. Its listed starting price is $10 with a free plan, but ingest and seat costs need close tracking. Developers can compare those charges against SigNoz’s usage-based pricing, then verify SDK coverage, ingestion options and data export for their workloads before switching.
Trade-off: Ingest and seat charges need monitoring as usage and team size grow.

$10/mofree plan - Self-hosted infrastructure monitoring
ZabbixZabbixZabbix is worth considering if avoiding per-device license fees and self-hosting matter more than a managed service. It has a free plan and is aimed at infrastructure monitoring, but setup and tuning take hands-on work. Before replacing SigNoz, map which telemetry signals your team needs and confirm the current integrations and export options for them.
Trade-off: Setup and tuning are your responsibility; confirm coverage for your telemetry.

Freefree plan - Broad hosted coverage
DatadogDatadogDatadog covers monitoring and security, and may suit organizations consolidating tools across cloud infrastructure. Its listed starting price is $500, so compare the applicable pricing units with your expected usage before moving. The published summary calls for checking pricing and integration details; verify SDK support, ingest paths and data export against your current SigNoz setup.
Trade-off: The listed starting price is $500; verify pricing and integration details.
6.2/10from
$500/mo - Code-level APM
Scout APMScout APMScout APM focuses on code-level traces and production context, making it a narrower alternative for teams prioritizing application performance over a broad observability stack. It is listed from $19 with a free plan and supports specific language stacks. Check that your languages are supported and confirm the available SDKs and migration path before replacing SigNoz.
Trade-off: Its focus is APM; verify language support and the signals you need.

Questions people ask
Which SigNoz alternative is closest for OpenTelemetry users?
Grafana is listed for OpenTelemetry and Prometheus users, while New Relic is positioned for OpenTelemetry-first instrumentation. Compare their current SDKs and ingestion options with your services, then check costs at your expected telemetry volume. The published pricing summaries list free plans for both, but do not establish your eventual bill.
Can I replace SigNoz with a free, self-hosted tool?
Prometheus is listed as free and intended for teams running their own monitoring; Zabbix has a free plan and is self-hosted. Their stated trade-offs differ: Prometheus requires you to run and scale servers, while Zabbix requires setup and tuning. Check signal coverage before treating either as a full replacement.
Does SigNoz put SSO behind a paywall?
A commenter in a self-hosting Reddit thread reported that SSO/OIDC was behind a price wall in the version they discussed. That report does not establish the current plan boundary. Check SigNoz’s current edition and pricing details, and confirm whether the authentication method your team requires is included before choosing a replacement.
