Sentry vs GlitchTip vs Self-Hosted Sentry: Error Tracking for a Small Team When the Event Quota Keeps Running Out

Description and use

For small teams, Sentry can quickly exhaust its event quota due to noisy errors. Adding client‑side deduplication via beforeSend, ignoreErrors, and sampleRate reduces event volume and prevents overage.

Problem

Small teams run out of event quota on hosted Sentry due to noisy incidents, making error tracking costly.

Outcome

Implementing client‑side deduplication and sampling reduces event volume by an order of magnitude, keeping hosted Sentry within quota and avoiding overage costs.

Workflow

• 1. Identify noisy incidents that generate repeated errors.
• 2. Add ignoreErrors for known network noise (e.g., ECONNRESET, AbortError).
• 3. Implement a beforeSend limiter that tracks error fingerprints and drops events exceeding a per‑window threshold.
• 4. Configure sampleRate for high‑volume noise if needed.
• 5. Verify that events are dropped before reaching the Sentry server.
• 6. Optionally enable server‑side spike protection or inbound filters for additional safety.

Evidence

Drop repeats at the source. The Sentry JavaScript/Node SDK exposes beforeSend, ignoreErrors and sampleRate

Source

A ten‑line beforeSend limiter removes the failure mode that makes every error‑tracking plan look too small.
