# Limits & fair use

These limits come from the product plans — not separate SLAs.

## Credits

|         | Free                | Pro               |
| ------- | ------------------- | ----------------- |
| Build   | 5/day (up to 30/mo) | 100/mo + 5/day    |
| Runtime | 20/mo               | 20/mo             |
| Top-ups | —                   | \$15 / 50 credits |

When build credits run out, the agent pauses. When **runtime** runs out on Free, published apps hard-pause. Details: [Credits](/billing/credits), [Hosting limits](/publish/hosting-limits).

## Live publishes

* Free: up to **10** live apps (also gated by runtime credits)
* Pro: up to **50** live apps (also gated by runtime credits)

## Sandbox idle

* Free: \~**5 minutes** idle then pause
* Pro: \~**30 minutes** idle then pause

Files remain; resume when you return (credits permitting).

## Attachments

Up to **5** files per message, **10 MB** each (logged-in).

Do not use Mythex to abuse infrastructure, spam, or violate the law. See the site legal pages (Terms / AUP) on [mythex.ai](https://mythex.ai). Report abuse of published apps via the product’s report paths when available.
