Five Sentry Alternatives That Go Beyond Basic Error Tracking
Sentry excels at errors, but you need more for full observability. Compare Datadog, New Relic, Bugsnag and more on monitoring scope, pricing and integration depth.
At MG Software we recommend Datadog for teams that want to consolidate their full observability stack. We choose New Relic for cost-effective monitoring thanks to the generous free tier. We suggest Highlight.io for teams that require open-source and self-hosting as a hard requirement. We help you choose the right monitoring platform and configure it for your stack.
Why do people look for alternatives to Sentry is the most widely used open-source error tracking platform, founded in 2012. It captures exceptions, errors and crashes across more than 100 programming languages and frameworks including JavaScript, Python, React, Next.js, Java and Go. Sentry provides stack traces, breadcrumbs, release tracking, performance monitoring and session replay. The Developer plan is free for 5,000 errors per month, Team costs $26 per month for 50,000 events and Business runs at $80 per month for 100,000 events. Sentry integrates with GitHub, GitLab, Slack, Jira and PagerDuty for a seamless workflow from error detection to resolution.?
Teams look for Sentry alternatives because the platform focuses primarily on error tracking and performance monitoring, while many organisations need a broader observability platform. Sentry does not offer log management, infrastructure monitoring or APM dashboards. Costs climb quickly at high event volumes: 100,000 events per month on Business already costs $80, and enterprise pricing is not published. Session replay is limited to web applications and adds latency to page load times. Teams that want to consolidate their entire observability stack need to run a separate tool for logs and metrics alongside Sentry.
Best alternatives
Datadog
Datadog is a full observability platform combining infrastructure monitoring, APM, log management, error tracking, real user monitoring and security monitoring in a single dashboard. The platform supports more than 750 integrations and offers AI-powered anomaly detection. Infrastructure monitoring starts at $15 per host per month, APM at $31 per host per month. Error tracking is available as part of the APM or RUM licence. Datadog is the market leader in enterprise observability.
Pros
- +All-in-one platform: infrastructure, APM, logs, errors, RUM and security in a single unified dashboard
- +More than 750 ready-made integrations for cloud providers, databases, frameworks and CI/CD tools
- +AI-powered anomaly detection and Watchdog alerts that surface problems before they become critical
- +Powerful query language and dashboards for correlating metrics, traces and logs in real time
Cons
- -Significantly more expensive than Sentry: combined licences for APM, logs and RUM add up to hundreds per month
- -Complex pricing structure with separate costs per host, per GB of logs and per session for each product
- -Steep learning curve for fully utilising all features and building effective monitoring dashboards
New Relic
New Relic is an observability platform offering APM, error tracking, infrastructure monitoring, log management, browser monitoring and synthetic monitoring. It stands out with a generous free tier of 100 GB data ingest per month across all products. The Standard plan costs $0.30 per GB above the free limit, Pro runs at $0.50 per GB. New Relic provides NRQL as its query language, alerting, dashboards and AI assistance via New Relic AI. The platform supports Java, .NET, Node.js, Python, Ruby, Go and PHP.
Pros
- +Generous free tier of 100 GB per month spanning all products without per-host limitations whatsoever
- +NRQL query language provides powerful analysis of every metric, trace, log and event in your stack
- +No per-host pricing model: you pay only for data ingest above the free limit measured in GB
- +Complete observability suite including APM, errors, logs, browser monitoring and synthetic checks
Cons
- -The user interface is more complex and less intuitive than Sentry for pure error tracking workflows
- -Data retention on the free plan is limited to 8 days, which may be insufficient for trend analysis
- -Costs become hard to predict with highly variable data volumes under the per-GB pricing model
Bugsnag
Bugsnag is a specialised error monitoring platform focused on application stability. It offers automatic error grouping, stability scores per release, breadcrumbs, feature flag integration and strong support for mobile apps alongside web. The free plan supports 7,500 events per month, Team costs $59 per month for 25,000 events and Business runs at $249 per month for 100,000 events. Bugsnag is owned by SmartBear and integrates with their broader testing platform.
Pros
- +Superior automatic error grouping that clusters related errors for faster and more accurate triage
- +Stability scores per release provide immediate insight into how each deploy affects application reliability
- +Strong mobile platform support: native SDKs for iOS, Android, React Native and Flutter development
- +Feature flag integration shows which flags were active when an error occurred for easier debugging
Cons
- -No performance monitoring, log management or infrastructure monitoring: purely focused on error tracking
- -More expensive than Sentry at comparable event volumes: Business costs $249 for 100,000 events versus $80
- -Smaller community and fewer open-source contributions than Sentry for framework-specific integrations
LogRocket
LogRocket combines session replay with error tracking and performance monitoring in a platform focused on understanding the user experience. It records sessions as video-like reconstructions of what users see and do, including DOM snapshots, network requests, console logs and Redux state. The free plan supports 1,000 sessions per month, Team costs $99 per month and Professional $249 per month. LogRocket is particularly valuable for reproducing bugs that are difficult to replicate locally.
Pros
- +Session replay shows exactly what the user did and saw when an error occurred for instant reproduction
- +Combines error tracking with UX analysis: identify bugs that cause the most user frustration
- +Redux, Vuex and NgRx state tracking reveals the exact application state at the moment of each error
- +Rage click and dead click detection helps identify UX issues that are not technical errors at all
Cons
- -No backend error tracking: LogRocket focuses on the frontend and completely lacks server-side monitoring
- -Session recordings increase the payload per page, potentially adding 50 to 100 ms to load times
- -Privacy-sensitive: session replay requires careful configuration to mask personal data properly
Highlight.io
Highlight.io is an open-source observability platform combining session replay, error monitoring, log management and tracing. It is designed as an all-in-one alternative to the combination of Sentry plus LogRocket plus a logging tool. Highlight offers a free tier for self-hosting, Cloud Free for 500 sessions per month and Pro from $150 per month. The platform is fully open-source under the Apache 2.0 licence and can be deployed on your own infrastructure.
Pros
- +Open-source and self-hostable: full control over data without dependency on external service providers
- +Combines session replay, errors, logs and traces in a single platform without separate tool subscriptions
- +Modern UI with fast search functionality and intuitive navigation between errors, sessions and logs
- +Transparent pricing without per-host costs or hidden overage charges on any plan tier
Cons
- -Younger platform with a smaller community and fewer integrations than Sentry or Datadog currently
- -Self-hosted version requires significant infrastructure: ClickHouse, Kafka and object storage needed
- -Less extensive language support than Sentry: focus is on JavaScript/TypeScript, Go and Python primarily
