About Bugsnag

BugSnag provides mobile and web app monitoring software. The product monitors crashes, performance bottlenecks, and traces requests across an application stack. A stability score indicates when to debug or build features. It includes an error inbox that shows bugs by severity and user impact. SmartBear's MCP server brings error data into an IDE and provides fix suggestions.

Used for

Monitoring crashes and slowdowns across customer moments such as purchases, streaming videos, or booking hotels.
Prioritizing bugs by severity to determine what to fix immediately.
Setting custom alerts and routing them to code owners.
Correlating crashes and traces to identify the microservice that caused a failure.
Viewing code used to build a version and changes from the previous version via source control integrations.

Who it is for

Development teams use the product to find and fix bugs.
Solo users running passion projects.
Smaller teams starting to monitor their apps.

How to evaluate APM & Distributed Tracing

This is how the CIOPages Research Team evaluates this category. It is not an assessment of Bugsnag. It comes from our Observability & APM Platforms buyer guide.

22%

Telemetry Coverage & Correlation

Unified metrics, traces, logs, real-user monitoring, synthetics, and continuous profiling; automatic correlation across signals; service maps and topology; Kubernetes, container, serverless, and cloud-provider auto-discovery; breadth and quality of the integration catalog

22%

Cost Control, Cardinality & Data Governance

Pricing-unit transparency and overage terms; high-cardinality handling without runaway cost; ingest-time filtering, sampling, aggregation, and tiered retention; a native or compatible telemetry pipeline; per-team budgets, quotas, and chargeback visibility so spend is governable, not just observable

20%

Distributed Tracing & APM Depth

End-to-end trace correlation across services and async boundaries, tail-based and adaptive sampling, code-level and method-level profiling, error tracking and exception grouping, database and dependency visibility, and frictionless OpenTelemetry trace ingestion alongside any native agent

16%

AIOps, Anomaly Detection & Root Cause

Quality of automated anomaly detection and alert noise reduction, causal versus correlative root-cause analysis, forecasting and capacity signals, and emerging agentic remediation — judged on accuracy during a real incident, not on the marketing name of the AI engine

12%

OpenTelemetry & Openness

Depth of native OTel support (traces, metrics, logs) versus a proprietary agent; whether collection is genuinely vendor-neutral or quietly locks you in; query-language portability; export and data-egress freedom; and how much re-instrumentation a future migration would actually require

Scale, Reliability & Operability

Proven performance at your peak event and series volumes, multi-region availability and platform SLA, data-retention options, RBAC and SSO, and — if self-hosted — the operational burden of running and upgrading the backend at high cardinality
