# Plans and credits (/get-started/plans-and-credits)

Every account starts on the Free plan. Pro and Ultimate give you more credits, more projects and more time each day. The [pricing page](https://paddlewheel.dev/pricing) always has the current plans.

## Credits [#credits]

A credit is one message to the agents. Each plan gets a number of credits every day, and a day's credits don't carry over to the next.

Sandbox time is how long your projects' machines can run each day. It resets at midnight UTC.

> **Custom domains need Pro or Ultimate**: Every project keeps its free `site.paddlewheel.dev` address on any plan, so moving to Free never takes an app offline.

## Plans belong to an organisation [#plans-belong-to-an-organisation]

A paid plan is billed to an organisation, and everyone in it shares the plan. To upgrade, open the menu with your name in the app and choose **Upgrade plan**.
