# Limits

This page lists the limits you can run into in EvoHub. Each product page explains its own in context; the link in each row goes there.

## Rate limits

| What | Limit |
| --- | --- |
| API requests | Counted per API key (or, without a key, per IP address) over a 10-second window: about 100 requests per second. Over it, the answer is **429** `RATE_LIMITED` with `Retry-After: 10`. See [Rate limits](https://docs.evohub.io/api-overview.md#rate-limits). |
| Alert ingest and heartbeat pings | Not rate limited, so a burst of alerts during an outage is never dropped for being too many. |
| Failed sign-ins | After 5 wrong passwords, the account is locked for 15 minutes. See [Sign in](https://docs.evohub.io/create-your-account.md#sign-in). |
| Changelog GitHub release imports | 10 imports an hour per changelog. See [Import GitHub releases](https://docs.evohub.io/writing-entries.md#import-github-releases). |
