# Rate limits

Source: https://www.pingtower.com/docs/reference/limits/

Per-plan rates on the ingest and data planes, and fixed limits on the routes that take a password.

| Plane | Free | Pro |
| --- | ---: | ---: |
| Ingest, per tenant | 20 req/s, burst 40 | 200 req/s, burst 400 |
| Data and account, per tenant | 10 req/s, burst 20 | 100 req/s, burst 200 |

Enterprise limits are set per tenant. Over a limit the response is `429` with `Retry-After` in whole seconds.

## Unauthenticated routes

Sign-up and login are limited per submitted email: a burst of five attempts, refilling at one per minute, so a drained burst is back in about five minutes. Account deletion and password-reset requests are limited the same way.

## Sizes

| --- | --- |
| Ingest `message` | 64 KiB |
| Ingest `keys` | 128 entries |
| Ingest `tags` | 64 entries |
| Rule `template_contains` | 500 characters |
| Escalation levels per rule | 10 |
| Action `body` | 8 KiB |
| Action `headers` | 32 |
| Report `description` | 4096 characters |
| Log tail `limit` | 200 |
