Deep dive: Sentry
When to choose Sentry
Sentry is the right choice for teams that prioritize error tracking quality and developer experience for crash reporting. Choose it if you're building web apps (React, Vue, Angular) or mobile apps where real-time error visibility is critical to your workflow. The $26/month tier works well for small teams or products with less than 100k events/month, providing excellent signal-to-noise ratio through smart grouping. It becomes the wrong choice for teams with massive scale (100M+ events/month) where volume pricing becomes prohibitive and cost per event balloons. Also wrong if you only need basic uptime monitoring without session replay or performance profiling—Better Stack would be significantly cheaper. Skip Sentry if you're bootstrapped and performance monitoring is nice-to-have rather than essential. Teams running multiple services often find Sentry most useful for their customer-facing applications rather than internal tools, where error rates are lower and issues impact revenue directly.
Real-world use case
A 3-person startup building a React SaaS app used Sentry's free tier for 6 months, capturing approximately 5k errors/month across their user base. When they hit 50k errors/month following a product launch, they upgraded to the $29/month Growth plan. They achieved 95% error capture through Sentry's smart grouping algorithm, reducing alert fatigue by 60%. Their on-call rotation improved dramatically from 15 wake-up alerts per week (mostly noise) to 3-4 actionable alerts weekly after fine-tuning their alert rules and ignoring known third-party issues. At $348/year investment, the ROI became immediately clear when one prevented production incident saved them $5k in lost revenue. They specifically avoided Datadog because its event pricing ($15 minimum monthly) would have cost 3x more at their volume. Within 18 months, Sentry's early detection caught a memory leak that would have forced an emergency rewrite.
Hidden gotchas
Event quotas reset monthly on a fixed calendar schedule, not dynamically—if you hit your limit on day 15, events are dropped for the remaining 15 days with no visibility. Upgrades don't retroactively apply to the current billing cycle, creating painful gaps mid-month. Session replay is charged separately as a completely different product tier, and can spike bills unexpectedly; 100 replays at 1MB each adds $5 to your monthly bill. Native SDK integration in React Native requires manual breadcrumbing for business logic visibility; auto-capture is extremely limited. The free tier's 5k events/month sounds generous until you add Webpack sourcemaps or integrate verbose logging libraries—one misconfigured logger can burn the entire quota in a week. Sentry's per-event pricing model means a DDoS attack or misconfigured application sending 10M junk events will bill aggressively; there's no hard rate limiter on free accounts. Performance monitoring and custom metrics consume separate quota pools, creating surprise overages.
Pricing breakdown
Sentry's free Developer plan covers 5,000 errors and 10,000 performance transactions per month — enough for a side project. The Team plan starts at $26/mo for 50,000 errors and 100,000 transactions. Business starts at $80/mo with more advanced features like custom dashboards and data forwarding. The real cost trap is volume: a single buggy deployment can burn through your monthly quota in hours. Sentry charges $0.000290 per error event and $0.000090 per transaction beyond your plan's included volume. For a mid-size SaaS (500k MAU), expect $200-600/mo on the Business plan.
Should You Use Rollbar or Sentry?
For most teams, Rollbar is the better default: it offers strong deploy correlation and is freemium (from $31/mo). Choose Sentry instead if best error tracking dx matters more than ui dated compared to sentry. There is no universal winner — the right pick depends on your budget, team size, and whether you value strong deploy correlation or best error tracking dx more.
Choose Rollbar if…
- •Strong deploy correlation
- •RQL for custom queries
- •Good free tier (5,000 events/mo)
Choose Sentry if…
- •Best error tracking DX
- •Great free tier
- •SDK for every language
