Best Error Tracking Tools in 2026
Error tracking tools catch, group, and surface application exceptions before users file bug reports — turning chaotic crash logs into actionable, assignable issues. The market ranges from pure-play error trackers like Sentry and Rollbar to full observability platforms like Datadog and New Relic that include error monitoring as one capability among many.
We evaluated six tools across pricing structure, SDK quality, error grouping intelligence, alerting, and developer experience. The right choice depends on whether you need best-in-class error context or a unified platform that also covers metrics, logs, and APM in a single pane of glass.
The best developer tools tools in 2026 are Sentry ($0–$80/month), Datadog ($0–$41/host/month), and New Relic ($0–$418.8/GB/month). Sentry is the best error tracking tool in 2026 for most teams. Its free Developer tier covers 5,000 errors/month, the Team plan starts at $26/month for unlimited users, and its SDK ecosystem (100+ languages and frameworks) is the deepest in the category. Teams that need unified APM plus errors should consider Datadog, while solo developers on a tight budget will find Rollbar's free tier (5,000 occurrences, unlimited users) or Bugsnag's free plan (50,000 events) compelling alternatives.

Our Rankings
Sentry
Sentry is the category default for a reason: it ships the deepest SDK ecosystem in error monitoring, with official SDKs for over 100 languages, frameworks, and platforms — Python, JavaScript, React, iOS, Android, Go, Ruby, and more. Its free Developer tier provides 5,000 errors/month for a single user; the Team plan at $26/month covers unlimited users and 50,000 errors with 14-day retention; and Business at $80/month adds 100,000 errors, 90-day retention, and SSO. Error grouping with configurable fingerprinting is best-in-class, and Sentry's breadcrumb trail (showing every network request, console log, and user action leading up to an error) gives developers the context to debug without reproducing the issue. It also supports performance monitoring and session replays at the same tiers, making it the logical starting point for any team that hasn't yet committed to a full observability platform.
- Free Developer tier: 5,000 errors/month — usable for production side projects
- Team plan at $26/month covers unlimited users (not per-seat pricing) with 50k errors
- 100+ official SDKs across languages, frameworks, mobile, and edge runtimes
- Best-in-class error grouping with custom fingerprinting rules to suppress noise
- Breadcrumb timeline shows network requests, console logs, and UI interactions leading to crash
- Session replay and performance monitoring included at same tiers — no separate product
- Free tier capped at 1 user — team collaboration requires a paid plan
- Self-hosted option exists but requires significant DevOps effort to maintain
- Costs scale with event volume; high-traffic apps can outgrow $26/month quickly
Datadog
Datadog's error tracking is not a standalone product — it's a feature inside its APM and Log Management suite. For teams already paying for Datadog APM ($31/host/month) or Infrastructure Pro ($18/host/month), error tracking adds zero marginal cost and integrates directly into distributed traces, making it trivial to jump from a JavaScript exception to the backend span that caused it. The free tier covers 5 hosts with 1-day retention, which is not suitable for production. Datadog's error tracking lags Sentry's grouping quality and SDK depth, but wins on cross-signal correlation: an error shows up in the same UI as the metric spike and the slow query that preceded it. Teams committed to Datadog's platform shouldn't pay separately for Sentry.
- Error traces link directly to distributed APM spans — no context switching between tools
- 1,000+ integrations including AWS, GCP, Kubernetes, and most CI/CD pipelines
- Log correlation: jump from an exception to the surrounding log lines in one click
- Anomaly detection and SLO monitoring built into the same platform
- Free tier available for evaluation (5 hosts, 1-day retention)
- Pricing is complex and per-host: $18-$41/host/month adds up fast for large fleets
- Error tracking is not best-in-class standalone — Sentry wins on grouping and SDK coverage
- Free tier retention is only 1 day, making it impractical for production debugging
New Relic
New Relic's pricing model is unlike any other platform here: the free tier includes 100GB of data ingest per month and 1 full platform user with access to all 50+ capabilities — including error tracking, APM, browser monitoring, and log management. Beyond 100GB, data costs $0.40/GB, and additional full platform users run $99-$418/month each depending on commitment. For a solo developer or a small team of one, New Relic's free tier is the most generous all-in-one observability bundle available, covering errors, traces, and logs without a paid plan. The limitation is user pricing: a 5-person team hitting $418/user/month on monthly pay-as-you-go makes New Relic significantly more expensive than Sentry at $80/month flat.
- Free tier: 100GB ingest/month + 1 full platform user — includes APM, errors, and logs
- Usage-based pricing beyond free tier: $0.40/GB is predictable for data-intensive apps
- 50+ capabilities under one platform login — no separate products for traces vs errors
- AI-assisted anomaly detection and error pattern analysis in higher tiers
- Generous free tier makes it practical for individual developers in production
- Full platform users cost $99-$418/month each — expensive for teams of 3+
- Data ingest model requires monitoring GB usage to avoid surprise bills
- Error grouping and SDK quality don't match Sentry's dedicated focus
Rollbar
Rollbar is a pure-play error tracker that doesn't try to be an APM platform. Its free tier is unusually developer-friendly: 5,000 occurrences/month, 1,000 sessions, unlimited projects, unlimited users, and 30-day retention — all without requiring a credit card. The Essentials plan at $15/month and Advanced at $32/month are flat-rate (not per-seat), keeping costs predictable. Rollbar's standout features are deploy tracking — linking every error to the specific deploy that introduced it — and RQL (Rollbar Query Language), which lets developers write SQL-like queries against their error data in the Advanced plan. It supports 30+ SDKs, fewer than Sentry but adequate for most stacks. The main limitation is the lack of session replay, performance monitoring, and the breadcrumb depth that Sentry provides.
- Free tier: 5,000 occurrences/month, unlimited users and projects — no credit card required
- Flat pricing at $15-$32/month (not per-seat) — predictable for any team size
- Deploy tracking links errors to specific releases, narrowing root cause investigation
- RQL query language (Advanced plan) for custom error data analysis
- REST API and Terraform provider included in all tiers
- No session replay or performance monitoring — error-only scope
- 30 SDK languages versus Sentry's 100+ — gaps in niche runtimes
- 5,000 free occurrences is low for busy production apps; paid plans start at 50k
Bugsnag
Bugsnag (now Insight Hub under SmartBear) has historically been strongest for mobile crash reporting on iOS and Android, where its SDK quality and diagnostic context — including device metadata, battery state, orientation, and memory pressure — exceeds what Sentry provides out of the box. Its free tier includes 50,000 monthly events (10x Sentry's free tier) covering solo users and passion projects. The Select plan at $20/month handles 150,000 events and the Preferred plan at $33/month covers 300,000 events, with performance monitoring added at that tier. The main drawback is that Bugsnag has narrowed its SDK breadth after the SmartBear acquisition, and its web and backend tracking trails Sentry and Rollbar for server-side use cases.
- Free tier: 50,000 events/month — the most generous free cap in the category
- Excellent mobile SDK quality for iOS and Android with rich device-context capture
- Flat pricing: $20-$33/month (not per-seat) for predictable team costs
- Stability scores and release health dashboards built into all paid tiers
- Performance monitoring added at the $33/month Preferred tier
- SDK breadth has narrowed post-SmartBear acquisition — fewer niche runtime SDKs
- Backend and server-side tracking is weaker than Sentry or Rollbar
- UI and alerting configurability lags behind Sentry's feature velocity
Grafana
Grafana does not have native error tracking in the Sentry/Rollbar sense — it is an observability platform (dashboards, Loki for logs, Tempo for traces, Mimir for metrics) that teams use to build their own error monitoring pipelines. Grafana OSS is free to self-host with zero feature limits; Grafana Cloud's free tier includes 50GB log ingestion and 10,000 Prometheus metric series, with the Pro plan starting at $19/month base plus usage-based costs. If your stack already sends errors to structured logs (Loki) or spans (Tempo), Grafana can surface them through dashboards and alerts without paying for a separate error tracking product. The trade-off is significant setup and maintenance work — Grafana does not give you SDK instrumentation, automatic error grouping, or breadcrumbs out of the box.
- Grafana OSS is fully free to self-host with no usage caps or feature gates
- Cloud Free tier: 50GB log ingest/month, 10,000 Prometheus series at zero cost
- Pro plan at $19/month base is the lowest entry price for a hosted observability platform
- Works with any data source that emits logs or traces — no vendor lock-in on instrumentation
- Native dashboarding excellence: best visualization layer in the observability ecosystem
- No native error tracking SDK — requires Loki or another log backend to capture errors
- Significant configuration required vs. drop-in solutions like Sentry or Rollbar
- Cloud Pro pricing is usage-based and can exceed $19/month base for high-volume apps

Frequently Asked Questions
01 What is the best error tracking tool in 2026?
Sentry is the best error tracking tool for most teams in 2026. Its free Developer tier covers 5,000 errors/month for solo developers, and the Team plan at $26/month supports unlimited users with 50,000 errors and 14-day retention. Sentry's SDK ecosystem spans 100+ languages and frameworks, and its error grouping with breadcrumb context — showing every network request and UI interaction leading up to a crash — is the deepest in the category.
02 Is there a free error tracking tool?
Yes — several tools offer genuinely useful free tiers. Sentry's free Developer plan covers 5,000 errors/month (1 user). Rollbar's free tier includes 5,000 occurrences/month with unlimited users and unlimited projects. Bugsnag's free plan is the most generous at 50,000 events/month. New Relic's free tier covers 100GB data ingest/month with 1 full platform user, which includes error tracking alongside APM and logs. Grafana OSS is entirely free to self-host.
03 How much does Sentry cost?
Sentry's Developer plan is free: 5,000 errors/month for 1 user. The Team plan costs $26/month and covers unlimited users with 50,000 errors and 14-day retention. The Business plan is $80/month with 100,000 errors, 90-day retention, and SSO. Enterprise pricing is custom with self-hosting options. All paid plans are flat-rate (not per-seat), so a 20-person team pays the same $26/month as a 2-person team.
04 What's the difference between Sentry and Datadog for error tracking?
Sentry is purpose-built for error tracking with best-in-class SDK coverage, error grouping, and breadcrumb context. Datadog's error tracking is a feature embedded inside its APM and infrastructure monitoring platform. If you're already paying for Datadog APM ($31/host/month), adding error tracking costs nothing extra and gives you direct trace correlation. If you only need error monitoring, Sentry at $26/month is cheaper and more capable. Teams on Datadog shouldn't pay for both.
05 What's the difference between Sentry and New Relic?
New Relic's free tier is more generous than Sentry's for full-stack observability: 100GB data ingest/month and 1 full platform user with access to APM, logs, and errors. But New Relic's per-user pricing ($99-$418/user/month for full platform users) makes it significantly more expensive than Sentry for teams of 3 or more. Sentry at $26/month covers unlimited users. For a solo developer who wants all observability signals in one place, New Relic's free tier wins on breadth.
06 Should I use Sentry or Rollbar?
Both are pure-play error trackers with flat (not per-seat) pricing. Sentry at $26/month supports 50,000 errors, adds session replay and performance monitoring, and has a broader SDK ecosystem (100+ vs 30+). Rollbar at $15/month supports a similar event volume and adds deploy tracking and RQL queries but lacks session replay. Sentry wins on feature depth; Rollbar wins on price if you only need error tracking and deploy correlation.
07 What is Bugsnag best for?
Bugsnag (now part of SmartBear Insight Hub) is strongest for mobile crash reporting on iOS and Android. Its SDKs capture rich device-context metadata — battery state, orientation, memory pressure — that makes mobile crash diagnostics faster than Sentry's mobile SDKs. Its free tier covers 50,000 events/month, the largest free cap in this comparison. For pure-web or server-side error tracking, Sentry and Rollbar offer deeper coverage.
08 Can I use Grafana for error tracking?
Grafana can surface errors if your application already sends them to a log aggregator like Loki or as traces to Tempo, but it does not include native error tracking SDKs, automatic error grouping, or breadcrumb capture. Grafana is an observability visualization and alerting layer, not a drop-in Sentry replacement. Teams self-hosting a Loki + Grafana stack can build custom error dashboards and alert rules, but it requires significant configuration that purpose-built tools handle automatically.
