Sentry vs Sumo Logic vs CubeAPM: Feature-by-Feature Breakdown

Known for

CubeAPM: Known for OpenTelemetry-native, end-to-end observability with customer-controlled deployment. It unifies metrics, logs, traces, error tracking, and user experience data in a single platform, offering unlimited retention and predictable pricing as telemetry volume scales. Teams commonly choose CubeAPM to reduce tool sprawl, control data residency, and manage observability costs long term.

Sentry: Known for developer-focused full-stack monitoring with strong in-code error tracking and application performance visibility. It is widely used to identify exceptions, performance bottlenecks, and release-level issues across backend, frontend, and mobile applications.

Sumo Logic: Known for unified observability with a strong emphasis on log analytics. It is commonly adopted for centralized log management, operational insights, and security monitoring in SaaS-first environments.

Multi-Agent Support

CubeAPM: Supports multiple telemetry agents and vendor formats out of the box. It is OpenTelemetry-native and can ingest data from OpenTelemetry collectors as well as existing vendor agents from New Relic, Datadog, and Elastic. This makes CubeAPM practical for teams migrating from commercial APM tools or running mixed agent setups without re-instrumenting everything.

Sentry: Supports OpenTelemetry through its SDKs and OpenTelemetry integrations. eams can use OpenTelemetry to generate traces and performance data and send that telemetry directly into Sentry as part of their application monitoring setup.

Sumo Logic: Supports OpenTelemetry and Prometheus for ingesting metrics, logs, and traces. Telemetry is typically collected via OpenTelemetry Collectors or Prometheus exporters and forwarded into the Sumo Logic SaaS platform, making it suitable for standardized, agent-based data collection in cloud and Kubernetes environments.

MELT Support (Metrics, Events, Logs, Traces)

CubeAPM: Provides native MELT support across metrics, events, logs, and traces in a single backend. Built on OpenTelemetry, all telemetry types are ingested, correlated, and queried together without separate storage engines or add-ons. This allows teams to move from a symptom in metrics to root-cause traces and logs in one workflow, which is especially effective for microservices and Kubernetes environments.

Sentry: Supports metrics, traces, and errors as part of its full-stack monitoring capabilities, with log support focused on contextual debugging. MELT coverage is strongest at the application layer, where traces, spans, and error events are tightly correlated with releases and code changes.

Sumo Logic: Supports MELT by ingesting logs, metrics, traces, and events into its SaaS platform. Its strongest capability is log analytics, with metrics and traces typically added to enrich log-driven investigations. Full correlation across MELT is available.

Deployment Model

CubeAPM: Supports self-hosted and BYOC deployments, running entirely inside the customer’s cloud or VPC. The platform is vendor-managed, so teams do not need to handle tuning, scaling, upgrades, or operational maintenance. This model is designed for organizations that want full control over data location and access while avoiding the overhead of operating an observability stack themselves.

Sentry: Primarily delivered as a SaaS platform, optimized for fast onboarding and minimal setup. A self-hosted option is available, but it requires teams to manage infrastructure, storage, scaling, and upgrades on their own. In practice, self-hosting adds operational overhead.

Sumo Logic: Offered exclusively as a fully managed SaaS platform. Telemetry data is collected from the customer’s environment and processed in Sumo Logic–managed infrastructure, which simplifies operations and scaling. However, because data is exported out of the customer’s cloud, teams may incur cloud provider data-egress costs as log and trace volumes increase.

Pricing: Approximate Cost for Small, Mid-Sized & Large Teams

*All pricing comparisons are calculated using standardized Small/Medium/Large team profiles defined in our internal benchmarking sheet, based on fixed log, metrics, trace, and retention assumptions. Actual pricing may vary by usage, region, and plan structure. Please confirm current pricing with each vendor.

*An APM host is a host that is actively generating trace data, and an Infra host is any physical or virtual OS instance that you monitor with any observability tool.

Below is a cost comparison for small, mid-sized, and large teams.

Approx. Cost for Teams	Small (~30 APM Hosts)	Mid-sized (~125 APM Hosts)	Large (~250 APM Hosts)
CubeAPM	$2,080	$7,200	$15,200
Sentry	$3,560	$12,100	$32,400
Sumo Logic	$4,641	$16,065	$33,915

Teams typically start noticing these cost differences once telemetry volume increases beyond early-stage usage, especially in environments with sustained traffic, high-cardinality logs, or multiple microservices. At this stage, observability spend often shifts from a fixed tooling cost to a variable expense that requires closer monitoring and forecasting.

For mid-sized teams, CubeAPM is approximately 40% more cost-effective than Sentry and over 55% cheaper than Sumo Logic, based on estimated costs for environments with around 125 APM hosts.

CubeAPM: Cost for Small, Medium, and Large Teams

CubeAPM prices observability based on the amount of telemetry processed, rather than user counts or host limits. The same pricing approach applies to logs, metrics, traces, and events, with long-term data storage included by default.

The platform charges:

• $0.15 per GB of telemetry ingested

For environments with similar workloads, the typical monthly spend is estimated as

• Small teams (~30 APM hosts): $2,080
  
• Mid-sized teams (~125 APM hosts): $7,200
  
• Large teams (~250 APM hosts): $15,200

Since costs rise in proportion to data volume, teams can forecast spending more easily as their systems expand.

Sentry: Pricing for Small, Medium, and Large Teams

Sentry’s pricing is structured around plan tiers, with costs influenced by factors such as event volume, performance units, and the number of team members. As observability usage increases, teams often move to higher tiers or incur additional usage charges.

Sentry’s pricing:

• Team: $26/month
• Business: $80/month

Based on comparable workloads and team sizes, estimated monthly costs are:

• Small teams (~30 APM hosts): $3,560
  
• Mid-sized teams (~125 APM hosts): $12,100
  
• Large teams (~250 APM hosts): $32,400

Because pricing is based on plans and data ingestion, spending can increase quickly as application traffic, tracing volume, or team size grows.

Sumo Logic: Cost for Small, Medium, and Large Teams

Sumo Logic pricing is driven primarily by data ingestion and retention tiers, with additional cost factors depending on enabled capabilities such as security analytics or advanced monitoring. As log volume grows, teams typically move into higher usage brackets, which increases overall spend.

Sumo Logic Estimated pricing:

• $3.14 per TB scanned

Using comparable environments and telemetry volumes, estimated monthly costs are:

• Small teams (~30 APM hosts): $3,870
  
• Mid-sized teams (~125 APM hosts): $11,875
  
• Large teams (~250 APM hosts): $26,750
  

Because pricing scales with log volume and retention choices, costs can rise steadily in log-heavy or high-traffic environments, especially as observability and security use cases expand.

Sampling Strategy

CubeAPM: Uses context-aware smart sampling designed to retain high-value telemetry while reducing overall volume. Sampling decisions prioritize error-heavy, high-latency, and anomalous traces, allowing teams to preserve critical signals during incidents while compressing routine traffic. This approach helps control cost without losing diagnostic depth in distributed systems.

Sentry: Supports head-based sampling, where sampling decisions are made at the start of a transaction and propagated downstream. It also offers dynamic sampling, which allows teams to adjust sampling rates based on conditions such as environment, transaction type, or error status. This gives flexibility at the application layer but requires manual tuning to balance data volume and visibility.

Sumo Logic: Supports multiple sampling approaches, including head-based sampling, tail-based sampling, and pattern-based filtering. Sampling rules are typically configured in the trace pipeline to reduce ingestion volume by filtering or shaping data before storage. This provides strong control for high-throughput environments but often involves more upfront configuration.

Data Retention

CubeAPM: Offers unlimited retention on metrics, logs, traces, or events. Because telemetry is stored inside the customer’s own cloud or BYOC environment, retention duration is determined by internal storage policies rather than plan constraints. Teams can retain observability data indefinitely without upgrading tiers or paying retention-based premiums, which supports long-term analysis, audits, and incident investigations.

Sentry: Enforces retention windows that vary by plan and data type. Most core data, including errors, logs, spans, and profiles, is retained for 30 days on lower tiers and up to 90 days on Business plans. Some transaction data may be stored longer in sampled form on higher plans, but full long-term retention typically requires exporting data outside Sentry.

Sumo Logic: Retention depends on the type of data being ingested. Normalized logs are typically retained for around 90 days by default, while security-focused data such as security signals can be retained for up to 2 years on applicable plans. Retention duration is closely tied to subscription level and directly affects overall cost as data volumes increase.

Support Channels and Response Time

CubeAPM: Offers support through email and shared collaboration channels such as Slack, with response times under 10 minutes. Support is geared toward production environments, with direct access to engineers when issues arise. 

Sentry: Provides support primarily via ticket-based and email channels, with access and responsiveness varying. Sentry does not publish fixed response-time SLAs across all plans, so response speed can differ.

Sumo Logic: Supports customers through in-app case submission, email, and Slack on eligible plans. Response-time targets are defined by priority and support tier. For critical issues (P1), initial response targets range from 30 minutes to 1 hour, while lower-priority issues typically receive responses within several hours to one business day, depending on the plan.

How Teams Evaluate These Platforms at Scale

When teams compare Sentry, Sumo Logic, and CubeAPM, the evaluation criteria often shift as systems grow in complexity and telemetry volume increases. Early decisions are usually driven by ease of setup and immediate visibility, while later-stage evaluations focus more on cost behavior, retention requirements, and operational control.

In production environments with sustained traffic and high-cardinality telemetry, teams tend to prioritize how pricing scales with ingestion, whether retention policies can be adjusted without sharp cost increases, and how much ownership they retain over observability pipelines. Platforms built around predictable ingestion-based pricing and flexible deployment models are often favored once observability spend becomes a recurring governance concern rather than a tooling experiment.
