# Tags

Tags are key-value pairs that help you organize and categorize your Spice projects. Use tags to label projects by environment, team, purpose, or any other dimension meaningful to your org.

## Managing Tags

1. Select your project.
2. Navigate to **Settings** and select **Tags**.
3. Enter a **Key** and **Value** for the new tag, then click **Save Tags** and confirm the change.

Tags are immediately associated with the project and visible to all org members.

> **Note**
>
> A small set of tag keys is reserved and managed by the platform. Reserved keys are hidden from the tags editor and cannot be added or removed there.

### Tag Limits

Tags are available on every plan, with no limit on the number of tags per project.

### Use Cases

Tags are useful for:

- **Environment labeling**: e.g. `env: production`, `env: staging`
- **Team ownership**: e.g. `team: data-engineering`
- **Cost tracking**: e.g. `cost-center: analytics`
- **Filtering and searching**: Quickly find projects by tag in the portal.
