# How many projects can I run on one instance?

> Builder includes 5 projects, Pro 15 and Business 30, and you can add more for $3 a month each. What projects share on an instance and how to tell when it's getting full.

Builder includes 5 projects, Pro 15, Business 30 and Enterprise a custom number. Beyond that, each extra project costs $3 a month. During the 7-day free trial you can create up to 3 projects; activating the paid plan early lifts that limit. In practice, how many projects fit depends on how busy they are, because every project on an instance shares the same VM.

## What each project gets

Every project is a full Supabase project: its own Postgres database, Auth users and settings, Storage, Realtime, Edge Functions, API URL (`https://<project>.<instance>.supahost.space`) and keys. Projects can't see each other's data.

## What projects share

| Shared across the instance | Builder | Pro | Business |
|---|---|---|---|
| CPU and memory | 2 shared vCPU, 4 GB | 2 vCPU, 8 GB | 4 vCPU, 16 GB |
| Database storage | 8 GB | 25 GB | 50 GB |
| File storage | 100 GB | 250 GB | 500 GB |
| Egress per month | 250 GB | 500 GB | 1 TB |
| Postgres connections | 400 | 400 | 400 |

Ten quiet side projects use far less than one busy app, so a Builder instance can often run several extra small projects alongside its 5 included ones. The capacity guide for a typical app (about 25,000 monthly active users on Builder, 50,000 on Pro and 100,000 on Business) is for the whole instance, not per project.

## Example: what 20 projects cost

On Pro (15 included, $49 a month): $49 + 5 × $3 = **$64 a month**. The same 20 projects on Business fit inside its 30 included projects for $99 a month.

## Adding a project

Dashboard → **Projects** → **New project**, or with the MCP `create_project` tool from an instance-scoped token (it asks you to confirm when the project goes beyond the plan). Names are 2 to 30 characters: lowercase letters, digits and hyphens, starting and ending with a letter or digit.

```
recipes-prod      ok
recipes-staging   ok
Recipes_Prod      not allowed (uppercase, underscore)
```

## FAQ

### Do branches count as projects?

Yes. A branch is a separate project with its own database, so it counts toward the plan's included projects and toward the 3-project trial limit.

### What happens when I delete a project?

Deleting a project (Settings tab → Danger zone → Delete project) stops it and archives its database.

### How do I know the instance is getting full?

Watch the quota tiles in **Usage & billing**; usage alerts email you at 80%, 90% and 100%. If the instance feels slow under load, see [High CPU usage on your instance](/kb/high-cpu) or move up a plan.
