Beyond error tracking. Full-stack observability in one platform.
Bugsnag excels at capturing and grouping exceptions. Atatus gives you the full context alongside every error: the backend trace, the slow query, the infrastructure state, and the real user session, correlated in one platform.
Monitoring capabilities in one platform — error tracking, APM, logs, infra, RUM
Technologies and cloud services supported for APM and infrastructure monitoring
G2 and Capterra rating across 90+ verified customer reviews
Human support on every paid plan — including during active production incidents
Bugsnag shows you the exception. Not what caused it.
Bugsnag tracks errors. Here is where its scope becomes a constraint for engineering teams that need more.
No Trace Correlation
Errors without the distributed trace that caused them
Bugsnag gives you the stack trace, breadcrumbs, and device state at the time of the exception. It has no link to the backend APM trace. You cannot see which service added latency, which database query was executing, or which external dependency failed in the same request. Atatus attaches the full distributed trace to every error — per-service spans, query execution time, and external call results — accessible directly from the error detail without switching tools.
No Infrastructure Visibility
Error spikes with no server-side context to explain them
Bugsnag has no visibility into host CPU, memory, pod health, or container restarts. When an error rate climbs, there is no way to tell from within Bugsnag whether the cause is a code regression, an OOMKilled pod, or a node under resource pressure. Atatus correlates error trends with host and Kubernetes metrics on the same timeline, so infrastructure-caused error spikes are identifiable without a separate tool.
No Log Ingestion
Application logs are not part of Bugsnag
Bugsnag captures structured breadcrumbs, not raw application logs. The database error message, the upstream response body, the failed config lookup — none of that is searchable inside Bugsnag. Engineers export to a separate log tool and query by timestamp, which adds steps to every investigation. Atatus ingests structured and unstructured logs natively and correlates them to errors by request ID, so relevant log lines appear in the error view automatically.
Know exactly when Atatus fits your team.
Bugsnag is purpose-built for error tracking. Here is when that scope becomes the constraint.
You need errors linked to the backend trace that caused them
Atatus connects every captured exception to the distributed trace that generated it — including per-service latency, database query duration, and external API calls. You see what the server was doing at the exact moment the error was thrown, without switching tools.
Database-level issues are surfacing as application errors
Slow queries, connection pool exhaustion, and N+1 patterns frequently manifest as application exceptions — a timeout, an unhandled null, a retry that eventually fails. Atatus profiles queries at the runtime level so you see the database cause, not just the application symptom.
Your error rate correlates with infrastructure events you can't see in Bugsnag
Pod restarts, node evictions, OOMKills, and CPU saturation all produce application errors — but Bugsnag has no awareness of the infrastructure layer. Atatus monitors Kubernetes and host-level metrics in the same platform, so error spikes can be traced to their infrastructure cause directly.
Your team spends time cross-referencing Bugsnag errors against logs in a separate tool
If every non-trivial error investigation ends in a separate log search tool, that's friction on every triage cycle. Atatus ingests logs natively and surfaces the relevant lines alongside the error — filtered by request ID, not by timestamp guesswork.
You need Core Web Vitals and session context alongside frontend errors
Atatus captures LCP, CLS, INP, FCP, and TTFB from real user sessions — not just error counts. Session replay shows exactly what the user was doing when the JavaScript exception fired, including the network request timeline and console output at that moment.
You want uptime monitoring and error tracking under one data model
When a Bugsnag error group spikes, you don't know if an endpoint is fully down or just degraded. Atatus runs uptime and synthetic checks alongside error tracking — so you can tell whether the error rate is a code regression or an availability event from a single dashboard.
Atatus vs Bugsnag
What Bugsnag does well, where it ends, and what Atatus covers in a single platform.
Atatus
Error grouping by root cause — stack trace fingerprinting to collapse duplicate errors into actionable groups, with volume and user-impact ranking
Error linked to the full APM trace — the distributed trace that triggered the exception is accessible directly from the error detail view
Release tracking — error rates per deployment version, with regression detection when a new release introduces a previously unseen error group
Custom metadata and user context — attach arbitrary key-value pairs to errors for segmentation by plan, region, tenant, or any business dimension
Bugsnag
Intelligent error grouping with configurable grouping rules to reduce duplicate noise
Errors are not linked to backend APM traces — stack trace and breadcrumbs are the extent of server-side context available at error time
Release health dashboard — stability score per release, crash rate trend, and promotion or rollback recommendations
Custom metadata support — attach user data and custom diagnostics to error events for filtering and prioritization
Bugsnag was good at grouping errors and showing us the stack trace. But every time an error spike hit, we spent 20 minutes correlating it across three tools: the APM dashboard for trace data, a log tool for the actual error message, and the infra console to rule out a resource issue. Moving to Atatus put all of that on one screen. The error, the trace, the logs, the host metrics, same view, same timestamp.

What teams ask before switching from Bugsnag.
Honest answers to the questions engineering teams ask before making the switch.
Atatus captures and groups errors by root cause using stack trace fingerprinting, with volume and user-impact ranking. Release-level error regression tracking is also included. The key difference is context: each Atatus error group links directly to the APM trace and log output, so you debug from the error detail rather than switching tools.
Atatus supports error tracking across Node.js, Python, Java, Ruby, PHP, .NET, Go, iOS, Android, and React Native, covering the primary production stacks most teams run. Bugsnag's SDK breadth across less common platforms and game engines (Unreal Engine, Unity) is a genuine advantage if your stack sits outside the mainstream. If you're on a standard web or mobile stack, Atatus coverage is complete. Verify your specific runtime during the trial.
It's a workflow problem that compounds with incident frequency. When an error group spikes, the investigation starts in Bugsnag, continues in the APM tool, filtered to the same time window, and then moves to the log tool to find the upstream error message or the config state at runtime. Each step requires re-establishing context. Atatus keeps all three in one data model, so the error detail page includes the trace and the relevant log lines correlated by request ID. There's no time window to set and no second tab to open.
Insight Hub represents Bugsnag's move toward broader observability, adding basic performance monitoring and OTel compatibility. The fundamental architecture is still error-centric: performance and infrastructure remain separate from the error workflow. Atatus was built from the start with a unified data model: errors, traces, logs, infrastructure metrics, and RUM are all first-class citizens of the same platform, correlated at ingest time, not bolted together at the UI layer.
Bugsnag pricing scales by event volume: the number of error and session events ingested per month. During traffic spikes or incident periods when error rates climb sharply, event usage can spike unpredictably. Atatus pricing is based on infrastructure footprint and data volume, which scales more predictably with your fleet size than with error rate variance. Additionally, Bugsnag's event model covers only error tracking. APM, log management, and infrastructure monitoring each require separate tools with their own pricing.
Replacing the Bugsnag SDK with the Atatus agent for supported languages (Node.js, Python, Java, Ruby, PHP, .NET) typically takes less than a day per service. The recommended path is a parallel run: Atatus running alongside Bugsnag for one to two weeks to validate error capture parity and alert thresholds before cutting over. Migration support is included on every paid Atatus plan at no additional cost.
