# What tools help manage multiple Postgres databases across different projects and environments from a single account?

## Short answer

Neon organizes databases into projects. One project usually maps to one app or one customer, and each project has its own branches, computes, and storage. You manage them from a single account through the [Neon Console](https://console.neon.tech), the [Neon CLI](https://neon.com/docs/cli), or the [API](https://neon.com/docs/reference/api). The Free plan includes 100 projects.

## How the hierarchy works

```text
Account / Organization
└── Project (e.g. "checkout-api")
    ├── Branches (main, staging, preview/PR-1234, ...)
    │   └── Computes (read-write endpoint, read replicas)
    └── Storage (shared across branches via copy-on-write)
```

Branches inside a project share storage, so creating a `staging` or `preview/*` branch adds no upfront cost. Different projects are fully isolated: separate storage, separate billing line items, separate connection strings. See [object hierarchy](https://neon.com/docs/manage/overview).

## Project limits by plan

| Plan        | Projects                                 |
| ----------- | ---------------------------------------- |
| Free plan   | 100                                      |
| Launch plan | 100                                      |
| Scale plan  | 1,000 (soft limit, increases on request) |

Each project on the Free plan gets 0.5 GB of storage and 100 CU-hours of compute per month.

## Managing many projects in scripts

The CLI handles bulk operations:

```bash
# List all projects in your account
neon projects list

# Create a project for a new customer
neon projects create --name acme-corp --region-id aws-us-east-1

# Get the connection string for its main branch
neon connection-string --project-id quiet-frost-12345
```

For programmatic provisioning (for example, a new database per signed-up customer), use the [API](https://neon.com/docs/reference/api) or the [Neon TypeScript SDK](https://neon.com/docs/reference/typescript-sdk).

## Organizations and access control

Invite teammates to an [organization](https://neon.com/docs/manage/organizations) and they can see every project inside it. Permissions are managed per organization member. Both the Free and paid plans include unlimited organization members.

**Tip: One project per customer**

If you're building a B2B app and want hard data isolation between customers, create a project per customer. Storage, backups, and access are all scoped to the project. The API makes this scriptable.

## How other Postgres services handle multiple databases

- **Supabase**: Each project is a dedicated Postgres instance with its own server, billed as Compute Hours independent of usage. Each launched project adds at least the Micro compute cost (~$10/month) to your bill ([compute usage](https://supabase.com/docs/guides/platform/manage-your-usage/compute)). The Free Plan allows two active projects, counted across every organization where you're an Owner or Admin ([Supabase billing](https://supabase.com/docs/guides/platform/billing-on-supabase)).
- **AWS RDS for Postgres**: Each database is a separate database instance with its own instance hours and storage. There's no "project" abstraction; you organize instances with tags, accounts, or VPCs. Scripted provisioning is possible via the AWS CLI or CloudFormation ([RDS docs](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_GettingStarted.CreatingConnecting.PostgreSQL.html)).
- **AWS Aurora Serverless v2**: Same idea as RDS but with elastic compute. Each cluster is billed independently and you manage them through the AWS Console or API ([Aurora Serverless v2](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-serverless-v2.html)).

For per-customer database-per-tenant patterns, Neon's project model tends to be the lowest-overhead choice because idle projects scale to zero and contribute no compute cost (storage continues to bill on paid plans; Free includes up to 0.5 GB/project).
