# Installation

> Run your own Postbase.

Postbase is a Next.js app backed by Supabase (Postgres + Auth). You can host it
anywhere that runs Next.js — Vercel is the smoothest path.

## Prerequisites

* Node.js 20+
* A [Supabase](https://supabase.com) project (Postgres + Auth)
* Object storage for media (Cloudflare R2 or any S3-compatible bucket)
* OAuth apps for the platforms you want to publish to (X, LinkedIn, etc.)

## Set up

<Steps>
  <Step title="Clone and install">
    ```bash theme={null}
    git clone https://github.com/postbasehq/postbase.git
    cd postbase
    npm install
    ```
  </Step>

  <Step title="Configure environment">
    Copy the example env file and fill in your keys — see
    [configuration](/self-hosting/configuration).

    ```bash theme={null}
    cp .env.example .env.local
    ```
  </Step>

  <Step title="Apply the database schema">
    Run the SQL migrations in `supabase/migrations` against your Supabase
    Postgres database (in order).
  </Step>

  <Step title="Run it">
    ```bash theme={null}
    npm run dev
    ```

    Then open `http://localhost:3000`.
  </Step>
</Steps>

<Note>
  For production, deploy to Vercel (or a Node host) and set the same environment
  variables there. Point `NEXT_PUBLIC_APP_URL` at your public origin — it's the
  OAuth issuer and MCP connector base.
