Sentry Pricing: Event-Based Billing Means a Single Bug Can Blow Through Your Monthly Quota
Updated 30 March 2026
Developer plan is free for 5K events. Team costs $26/month for 50K events. Business costs $80/month for 100K events. The pricing seems simple until a bug affecting 10% of users generates 300,000 events in a day. Here is how to predict your real usage and avoid overages.

Event Volume Pricing Beyond Included Quota
When you exceed your included events, Sentry charges per additional event. The overage rates incentivize fixing bugs: fewer errors mean lower costs.
$0.00025
Per error event (overage)
100K extra errors = $25
$0.000025
Per transaction event (overage)
1M extra transactions = $25
Example: 500K error events/month on Team plan
What Counts as an Event
Error Events
$0.00025/event (overage)Unhandled exceptions and errors you explicitly capture with Sentry.captureException() or Sentry.captureMessage(). These are the highest-cost events. A single unhandled exception in production can generate thousands of error events per hour if it affects many users.
Transaction Events
$0.000025/event (overage)Performance monitoring spans that track request timing, database queries, and API calls. Transaction events are 10x cheaper than error events. At a 20% sample rate, a 100K DAU app generates approximately 1.2M transaction events/month.
Replay Events
Separate quotaSession replays that record user interactions before and after an error. Available on Business plan and above. Replays help reproduce bugs by showing exactly what the user was doing. Replay events have their own quota separate from error and transaction events.
Attachment Events
Separate quotaMinidumps, screenshots, and other binary attachments sent with error events. Used primarily for native applications (iOS, Android, desktop). Attachments have file size limits and their own storage quota.

Sentry recommends 10-20% for production. 100% captures everything but costs more.

Datadog APM Comparison
Datadog APM for similar scale (~2 hosts): approximately $30/month for APM only. Sentry at $26.50/month is cheaper for error tracking. Many teams use both: Sentry for error tracking and Datadog for infrastructure monitoring.
Estimates based on DAU, error rate, and session volume. Actual event volume depends on application error handling, SDK configuration, and usage patterns. Sentry's pricing can change; verify current rates on sentry.io.
Managing Event Volume
Set transaction sample rates to 10-20%
80-90% reduction in transaction eventsInstead of capturing every transaction, sample 10 to 20% in production. This reduces performance monitoring event volume by 80 to 90% while still providing statistically meaningful data. A 20% sample rate on 100K daily transactions gives you 20K representative samples, which is sufficient for identifying slow endpoints and p95 latency issues.
Use inbound data filters
10-30% reduction depending on app typeSentry's server-side inbound data filters drop known irrelevant errors before they count against your quota. Filter out: browser extension errors (common in web apps), localhost/development errors that accidentally reach production, known bot and crawler user agents, and legacy browser errors (IE11, old Safari) that you cannot fix.
Configure rate limiting
Prevents surprise overage chargesSet per-key rate limits to prevent a single bug from consuming your entire monthly quota. For example, limit each SDK key to 1,000 events per hour. If a deployment introduces a bug affecting 50% of users, rate limiting caps the damage to 1,000 events/hour instead of potentially millions. You still see the bug and its frequency, but without the runaway costs.
Use beforeSend hooks
Variable, depends on filtering rulesThe Sentry SDK supports a beforeSend callback that runs before each event is sent to Sentry. Use this to conditionally drop events client-side: filter out known issues you have accepted, drop events from specific user segments (internal testing users), and redact sensitive data before transmission. This reduces both event volume and data privacy risk.
Fix high-frequency bugs quickly
Directly proportional to bug frequencyThe most effective cost management strategy is simply fixing bugs. A single unhandled exception in a hot code path can generate 10,000+ events per day. Fixing it eliminates those events permanently. Sentry's issue grouping shows which bugs produce the most events, making it easy to prioritize fixes by cost impact.
