Datadog Alternatives: Affordable Observability Without Feature Compromise
Datadog is powerful but pricey. Five monitoring platforms compared on cost, data limits and flexibility for teams that want to stop overpaying.
At MG Software we recommend Grafana Cloud for teams that want open-source flexibility with a generous free plan. New Relic fits better for teams that prefer a fully unified platform without per-host pricing. We help you choose the monitoring stack that matches your budget and scaling requirements.
Why do people look for alternatives to Datadog is a cloud-native observability platform combining infrastructure monitoring, application performance monitoring (APM), log management, real user monitoring (RUM), synthetic monitoring and security monitoring in a single SaaS solution. The platform integrates with over 750 technologies through out-of-the-box integrations. Datadog offers powerful dashboards, machine learning anomaly detection, distributed tracing and a correlation engine that links logs, metrics and traces together. Pricing starts at $15 per host per month for Infrastructure monitoring, $31 per host for APM and $0.10 per GB for ingested logs. For teams running dozens of hosts and ingesting terabytes of logs, the monthly bill can quickly reach thousands of dollars.?
Teams look for Datadog alternatives primarily because of cost. The per-host and per-GB pricing model leads to unpredictable bills that grow exponentially as infrastructure scales. Many organisations report their Datadog costs doubling after enabling APM, RUM or log management on top of basic monitoring. Vendor lock-in is significant: migrating dashboards, alerts and queries to another platform takes weeks of engineering effort. Datadog retains historical data for only 15 months by default, which is restrictive for compliance-sensitive industries. Teams also find that the platform complexity increases as they activate more products, slowing down onboarding for new team members.
Best alternatives
Grafana Cloud
Grafana Cloud provides a fully managed observability stack built on open-source technologies: Grafana for visualisation, Prometheus/Mimir for metrics, Loki for logs and Tempo for traces. The free plan offers 10,000 metrics series, 50 GB logs and 50 GB traces per month. Pro plans start at $29 per month. The platform supports OpenTelemetry natively and provides over 120 datasource plugins. Grafana Labs added Incident and OnCall in 2025 for integrated incident management.
Pros
- +Generous free plan with 10,000 metrics, 50 GB logs and 50 GB traces covering many startups entirely
- +Open-source core: no vendor lock-in with full portability of dashboards and queries to self-hosted Grafana
- +Native OpenTelemetry support making instrumentation independent of the observability backend
- +Flexible datasource integration with over 120 plugins for diverse data sources and monitoring systems
Cons
- -Multiple backends (Mimir, Loki, Tempo) require understanding of individual query languages PromQL and LogQL
- -Correlation between metrics, logs and traces is less seamless than in Datadog's unified platform
- -Enterprise features such as SAML SSO and advanced RBAC are only available on the Advanced plan
New Relic
New Relic provides an all-in-one observability platform with APM, infrastructure monitoring, log management, browser monitoring, synthetic monitoring and AIOps. The free plan is exceptionally generous with 100 GB of free data ingest per month and one full platform user. Paid plans charge $0.35 per GB above the free allowance and $49 per full platform user per month. New Relic supports over 580 integrations and offers NRQL, a powerful SQL-like query language for all telemetry data.
Pros
- +Exceptionally generous free plan with 100 GB data ingest per month, sufficient for many mid-size teams
- +Unified platform where APM, logs, infrastructure and browser monitoring share the same query language (NRQL)
- +Integrated AIOps with anomaly detection, related entities and automatic root cause analysis
- +Transparent per-GB pricing model instead of per-host, making costs more predictable with scalable infrastructure
Cons
- -Per full-platform user cost of $49 per month adds up quickly for large teams with dozens of engineers
- -The interface can overwhelm new users due to the breadth of features and configuration options available
- -Data retention on the free plan is limited to 8 days, insufficient for longer-term trend analysis
Sentry
Sentry focuses primarily on error tracking and application performance monitoring. The platform provides real-time error monitoring with stack traces, breadcrumbs, release tracking, session replay and performance tracing. The free Developer plan includes 5,000 errors and 10,000 performance events per month. The Team plan starts at $26 per month and Business at $80 per month. Sentry supports over 100 platforms and frameworks and is also available as a self-hosted option.
Pros
- +Deep error context with stack traces, breadcrumbs, user information and release correlation per event
- +Session replay shows exactly what a user did before an error occurred without separate tooling
- +Open-source self-hosted option for teams that want full control over data and privacy
- +Low barrier to entry: SDK integration typically takes less than five minutes per framework
Cons
- -No infrastructure monitoring: you need a separate platform for server metrics, container monitoring and networking
- -Log management is absent, meaning Sentry cannot function as a standalone observability solution
- -Costs scale quickly for applications with high error volumes due to the event-based pricing model
Prometheus + Grafana (self-hosted)
The combination of Prometheus for metric collection and Grafana for visualization is the de facto standard for open-source monitoring. Prometheus uses a pull-based model with PromQL as its query language and provides built-in alerting through Alertmanager. Grafana visualizes the data with configurable dashboards, template variables and alert rules. Both tools are free and open-source. The community offers thousands of pre-built dashboards and exporters for virtually every service.
Pros
- +Completely free and open-source: zero licensing costs regardless of the number of hosts, metrics or users
- +Industry standard with PromQL as a query language that transfers to any Prometheus-compatible platform
- +Thousands of community exporters and dashboards available for monitoring databases, queues, containers and more
- +Full control over data retention, storage configuration and security policies without third-party dependency
Cons
- -Self-hosting requires significant operational knowledge for scaling, high availability and long-term storage
- -No native log management or distributed tracing: you must set up Loki or Tempo separately
- -Vertical scalability of Prometheus is limited: large volumes require Thanos or Mimir as an additional layer
Uptrace
Uptrace is an open-source APM tool built on ClickHouse that processes OpenTelemetry data for traces, metrics and logs in a single dashboard. The cloud plan starts at $30 per month for 50 GB of data. The self-hosted version is free and open-source. Uptrace offers span grouping, service maps, alerting and SLO monitoring. The platform distinguishes itself through low cost per GB thanks to ClickHouse storage efficiency and native OpenTelemetry support.
Pros
- +Very low cost per GB due to ClickHouse storage that compresses more efficiently than traditional backends
- +Native OpenTelemetry-first design: no proprietary agents needed, only standard OTel SDKs and collectors
- +Traces, metrics and logs in a unified interface with correlation via trace IDs and span attributes
- +Self-hosted option on your own ClickHouse infrastructure for full data ownership and compliance
Cons
- -Smaller ecosystem and fewer integrations than Datadog, Grafana Cloud or New Relic
- -Community and documentation are more limited, making troubleshooting edge cases harder
- -Self-hosted installation requires ClickHouse expertise that not every team possesses
Comparison at a glance
Grafana Cloud offers the most flexibility with open-source backends and a generous free plan. New Relic delivers a fully unified platform with per-GB pricing instead of per-host. Sentry excels at deep error tracking and session replay for application-level insight. Prometheus with Grafana provides maximum control at zero licensing cost. Uptrace reduces costs via ClickHouse storage and native OpenTelemetry support.
What to consider when switching?
- Current monthly Datadog spend versus monitoring budget and expected infrastructure growth trajectory
- Need for unified metrics, logs and traces in one platform versus acceptance of multiple specialised tools
- Preference for managed SaaS versus self-hosted solutions with associated operational overhead
- Investment in OpenTelemetry instrumentation that simplifies migration to any OTel-compatible backend
