Deep dive: Better Stack
When to choose Better Stack
Choose Better Stack if you want one unified platform for uptime monitoring, alerting, and log management without paying enterprise-grade prices. It's ideal for teams under 50 people running 5-20 services that need operational visibility without overwhelming complexity. The $0 entry point and genuinely generous free tier make it perfect for bootstrapped startups, side projects, and small teams. It's the wrong choice if you need advanced observability features like distributed tracing across microservices, complex custom metrics, or strict compliance certifications—while SOC2 is available, it's less mature than competitors. Also wrong for teams already standardized on ELK Stack or Prometheus where switching costs outweigh the UX improvements. Better Stack lacks the depth of Datadog for large organizations running hundreds of services. Skip it if you need Kubernetes-native monitoring with automatic service discovery, as Better Stack requires manual setup.
Real-world use case
A 2-founder SaaS company built on Rails used Better Stack's free tier for the first 6 months to monitor 3 critical API endpoints and ship Kubernetes cluster logs. Their total hosting cost: $0. When they reached $500/month revenue, they upgraded to the $99/month Professional plan to add on-call escalation, SMS alerts, and longer log retention. They specifically avoided the alternative of paying Datadog ($15+ per monitored host) and PagerDuty ($99+ per team member). With Better Stack's unified dashboard, their DevOps overhead dropped from 4 hours/week (managing separate Uptime Robot, Slack integration, and CloudWatch separately) to just 1 hour/week. SQL-based log queries saved approximately 30 minutes on each incident investigation. Real annual cost: $1,188 versus $300+ for equivalent Datadog + PagerDuty combination. By month 12, they had resolved 40 incidents 50% faster.
Hidden gotchas
Log retention on the free tier is only 7 days; paid plans offer 30-90 days but never unlimited. No automatic log sampling or compression, so high-volume applications (1M logs/day) hit storage limits unexpectedly fast. Webhook delivery for alerts is reliable but has no built-in retry backoff mechanism; failed deliveries silently drop without notification. The platform doesn't auto-detect Kubernetes metrics like Datadog does with their integration—you must manually ship kubelet data or set up Prometheus exporters. Alert routing is intentionally simple (single linear escalation chain) compared to PagerDuty's sophisticated on-call schedules and geo-routing. Custom metrics aren't supported; you're limited entirely to pre-built dashboards and pre-defined alert types. The mobile app is basic and doesn't support alert acknowledgment directly in-app, forcing you back to email. API documentation is sparse with limited code examples, making custom automation and integrations difficult.
Pricing breakdown
Better Stack (formerly Logtail) starts free for uptime monitoring (up to 5 monitors, 3-minute checks). The Plus plan at $24/mo adds 1-minute checks, 25 monitors, and status pages. For logging, the free tier includes 1 GB/mo of log data with 3-day retention. The Pro logging plan starts at $30/mo for 30 GB with 30-day retention. The real value is bundling: monitoring + logging + incident management in one platform costs roughly 40-60% less than running separate Datadog + PagerDuty + StatusPage subscriptions. Watch the log volume — each additional GB beyond your plan is $1-2/mo.
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 Better Stack or Sentry?
