Is 5,000 Events Per Month Enough?
| App Type | Typical DAU | Est. Monthly Errors | 5K Enough? |
|---|---|---|---|
| Personal blog / portfolio | 10-100 | 10-50 | Yes, easily |
| Side project SaaS | 100-500 | 50-500 | Yes, with room |
| Early startup (pre-launch) | 100-1K | 100-2K | Probably yes |
| Growing startup | 1K-5K | 500-10K | Borderline |
| Production SaaS app | 5K-50K | 2K-50K+ | No, need Team ($26/mo) |
| Mobile app (iOS/Android) | 10K+ | 5K-100K+ | No, need Team or Business |
Maximizing Your Free 5K Quota
Disable performance monitoring
Transaction events share the 5K quota with error events. On the free plan, disable performance monitoring entirely (set tracesSampleRate to 0 in your SDK config). Use the full 5K quota for error tracking, which is more valuable for debugging.
Use inbound data filters aggressively
In Sentry's project settings, enable inbound data filters to drop known irrelevant errors. Filter out browser extension errors (they pollute web app error tracking), localhost and development environment errors, known bot/crawler user agents, and legacy browser errors you cannot fix.
Configure beforeSend to drop noise
In your SDK configuration, add a beforeSend callback that filters out low-value errors client-side before they are sent to Sentry. Drop network errors from third-party scripts, CSP violation reports, and errors from specific user agents (bots, old browsers).
Set up a daily rate limit
Sentry allows rate limiting per DSN key. Set a daily limit of ~170 events/day (5,000 / 30 days) to ensure your quota lasts the full month. Without a rate limit, a single bad deploy can consume your entire monthly quota in hours, leaving you blind for the rest of the month.
Fix high-frequency errors immediately
When you see an error generating 50+ events per day, fix it immediately. On the free plan, every event counts. A single recurring error consuming 50 events/day wastes 1,500 events/month, which is 30% of your quota. Sentry's issue grouping shows which errors produce the most events.
