# Plans and limits

What each plan includes and where the limits sit

Plans apply per organization and bill monthly, with the cycle anchored to your signup date. Every account starts on Free with no payment method required.

### How limits behave

* Unused compute units expire at the end of each cycle. There is no rollover.
* On Free, reaching the monthly CU cap blocks further requests with HTTP 402 until the next cycle. Growth and Pro continue serving and bill the excess as overage.
* Exceeding your throughput limit returns HTTP 429 on the excess requests. See [rate limits and errors](/rpc/rate-limits-and-errors.md).
* All plans include all four chains over HTTPS.

### Enterprise

Enterprise plans add custom limits and rates, dedicated infrastructure and an account manager. Contact <rpc-support@luganodes.com> to discuss requirements.
