Error-event quota
The listed monthly quota covers browser and API error events accepted into ErrorNotifier projects for that plan.
Rate limits
Project keys also have per-minute safety limits. Ingestion returns HTTP 429 when a key is temporarily rate limited, so SDKs should back off and retry later.
Replay metadata
Replay storage is metadata-first today. Growth and higher plans reserve replay metadata capacity; ErrorNotifier is not marketed as a session replay product.
