Short answer: you'll get a warning at 80% of your monthly event cap, a final notice at 100%, and then one of two things happens depending on your plan settings — either tracking pauses, or events overflow into pay-as-you-go billing.
The two modes
Every paid plan has a setting for what happens when you hit your monthly cap.
Mode 1: Pause tracking (default on Free, optional on paid plans)
When you hit 100% of your monthly cap:
- New events are dropped at the edge — they never enter your database, so they don't count, but they also don't appear in any report.
- Existing data stays accessible — historical events, dashboards, exports all keep working.
- The dashboard shows a banner explaining the cap and linking to upgrade options.
- The cap resets at the start of your next billing cycle (the 1st of the month for Free, your subscription anniversary for paid plans).
This mode is the default on the Free plan and you cannot opt out — Free has no overage billing.
Mode 2: Pay-as-you-go overage (Pro and Scale)
When you hit 100% of your monthly cap and you've enabled overage billing:
- New events keep being collected — nothing is lost.
- Each block of additional events is billed at the published per-block price (see pay-as-you-go pricing for the exact rate per plan).
- You get a notification the first time overage kicks in, and a daily summary if it continues.
- You can cap the overage spend — set a hard ceiling in Settings → Billing → Overage limits. Once you hit the ceiling, mode automatically switches to "pause tracking" until the next cycle.

What to do if you keep hitting the cap
- Upgrade — usually cheaper than the overage charges if you consistently exceed the cap.
- Trim what you track — disable outbound-link tracking or heartbeats if you don't analyze them.
- Add filters at the tracker — use
