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.

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 or move up a plan.
