ScoutAPM is a lightweight, developer-focused application performance monitoring tool designed specifically for teams using Ruby, Python, Elixir, and PHP. It delivers fast, automatic tracing, intuitive N+1 query detection, and memory bloat alerts with minimal setup.

However, ScoutAPM lacks certain features, such as RUM and synthetic testing. Plus, if logs exceed 1GB per month and 5,000 errors per month, respectively, you will need to take logs and error monitoring add-ons, which cost extra. It’s a SaaS-based platform with no self-hosting or on-premise deployment, which could be a concern for compliance-focused businesses.

CubeAPM stands out as the best ScoutAPM alternative with built-in RUM and synthetic monitoring and full self-hosting to help businesses meet compliance requirements. Its capabilities include smart sampling, intelligent alerting, intuitive dashboards, etc., all under a simple pricing of $0.15/GB with no extra charges for logs, error monitoring, data retention, or egress.

In this article, we explore 7 top ScoutAPM alternatives, based on features, pricing, deployment options, and more.

Why People Are Looking for ScoutAPM Alternatives

Missing Features

Scout APM excels at identifying application-level performance bottlenecks like N+1 queries, memory bloat, and slow database calls. However, features such as synthetic testing and real user monitoring (RUM) are not yet supported by Scout APM, according to their documentation. Teams requiring those functions may have to use other tools, which adds complexity and cost.

absence of OpenTelemetry support and lack of self-hosting options further restrict Scout’s suitability for cloud-native or enterprise-grade environments.

Extra Charges

Scout APM offers a free plan with 300k transactions/month, while paid plans cost $19-$299/month with fixed monthly transaction quotas (e.g., 600k/month-9M/month) with unlimited users. However, if you need additional log management and error monitoring, you will need to purchase add-ons. The log monitoring add‑on is priced at $40/month for 30 GB storage. But users consuming more telemetry incur overages at $0.46/GB. Similarly, the error monitoring add-on is priced at $19/month for 50,000 errors. Since no synthetics and RUM are available, you will require different tools if you need these functionalities.

No Self-Hosting

Scout APM is a SaaS platform, with no mention of self-hosting or on-premise deployment on their website at the time of writing this article. Although they mention that users can opt for a custom plan, the details are not mentioned. Since the platform is SaaS, the data goes through their servers, which might not be suitable for organizations with strict data sovereignty needs.

Criteria for Selecting ScoutAPM Alternatives

1. OpenTelemetry-Native Support

The alternative should fully support OpenTelemetry (OTEL) as a first-class citizen, enabling standardized telemetry collection and seamless migration across tools. Native OTLP ingestion eliminates vendor lock-in and supports scalable instrumentation across languages and frameworks.

2. Full MELT Coverage (Metrics, Events, Logs, Traces)

Modern observability requires unified insights, not just traces. Ideal platforms should offer integrated metrics dashboards, log search, distributed traces, event timelines, and anomaly detection in one UI for holistic debugging and analysis.

3. Smart or Tail-Based Sampling

Alternatives must include advanced sampling techniques like tail-based or context-aware sampling. These reduce noise and retain only high-value traces (e.g., error-prone, slow spans), helping teams optimize visibility without incurring high data volume costs.

4. Transparent, Scalable Pricing

Clear and predictable pricing—preferably based on data volume rather than transactions or host count—is key. Platforms like CubeAPM offer flat per-GB pricing with no hidden user or retention fees, unlike ScoutAPM’s overage-based billing model.

5. Long-Term Retention Options

Retaining data for 30, 60, or 90 days (or longer) should be possible without expensive upgrades. This is essential for postmortem analysis, SLA audits, performance benchmarking, and tracking regressions across releases.

6. Support for RUM and Synthetic Monitoring

Alternatives should provide built-in Real User Monitoring (RUM) to capture frontend performance and Synthetic Monitoring to simulate user journeys. These capabilities help measure user experience and uptime, which Scout lacks entirely.

7. Self-Hosting or Hybrid Deployment Options

Compliance-focused teams need flexibility to deploy observability tools on-prem or in private clouds. A strong alternative should offer both SaaS and self-hosting options to meet data residency, privacy, or air-gapped environment needs.

8. Responsive and Reliable Support

Enterprise-ready platforms should offer fast support through Slack or live chat, not just slow ticketing systems. Real-time help during outages or onboarding accelerates adoption and reduces MTTR during incidents.

9. Ease of Migration from ScoutAPM

Seamless onboarding, agent compatibility (e.g., OTEL, Prometheus, New Relic formats), and import tools help reduce friction while switching. Platforms with built-in agent support or no-code setups allow teams to transition within hours.

Sumo Logic vs ScoutAPM

Sumo Logic offers a more holistic observability and security platform compared to ScoutAPM, which focuses mainly on application tracing. While Scout is better suited for simple backend debugging, Sumo Logic excels in high-scale, log-heavy environments that require compliance dashboards and security insights. However, its tracing capabilities and OTEL support lag behind modern standards, making it less appealing for teams needing deep service-level observability.

Conclusion: Choosing the Right ScoutAPM Alternative

While Scout is excellent for small teams and backend performance debugging, it lacks certain functionalities, such as synthetic testing and RUM. It charges extra for add-ons for log management and error tracking beyond 1 GB and 5,000 errors, respectively. In addition, it lacks an on-premise or self-hosting option, which may not be suitable for orgnizations with strict data compliance requirements.

CubeAPM stands out as the best ScoutAPM alternative with a full-stack observability platform, including RUM and synthetics. It’s simple $0.15/GB pricing is uniform for logs, traces, metrics and events, with nothing charged extra. It’s smart sampling filters low-value data to further reduce costs. It also offers a self-hosting option on your on-premise systems or cloud infrastructure to help you meet data sovereignty needs.
