# Free tier

Solo's free tier lets you use every part of the app without a paid license, with limits on projects and managed processes.

## Limits

| Resource | Free limit |
|----------|------------|
| Primary projects | 4 |
| Processes | 20 |

"Processes" means commands, [agents](../agents/what-are-agents.md), and terminals managed by Solo.
Linked checkout/worktree projects do not count toward the four-primary-project quota.

## What happens at the limit

- If you are at 4 primary projects, adding another primary project opens the license prompt. Linked checkout/worktree projects do not count toward this limit.
- If you are at 20 processes, adding another process opens the license prompt.
- If you are unlicensed and already over either limit, Solo blocks process starts until you activate a license or reduce usage.
- If you [deactivate a license](./moving-license.md) while over the free limits, Solo returns to the free tier locally and stops running managed processes.

## Upgrade path

Activate a license from **Settings > Account** or the title bar prompt to remove free-tier limits. By default, `Cmd/Ctrl+,` opens Settings; you can change this shortcut in **Settings > Hotkeys**. See [Activating a License](./activating-license.md) for the steps.
