This quickly shows how to connect your Prisma application to Supabase Postgres. If you encounter any problems, reference the [Prisma troubleshooting docs](/docs/guides/database/prisma/prisma-troubleshooting).

<Admonition type="note">

If you plan to solely use Prisma instead of the Supabase Data API (PostgREST), turn it off in the [API Settings](/dashboard/project/_/settings/api).

  <StepHikeCompact.Step step={1}>
    <StepHikeCompact.Details title="Create a custom user for Prisma">
      - In the [SQL Editor](/dashboard/project/_/sql/new), create a Prisma DB user with full privileges on the public schema.
      - This gives you better control over Prisma's access and makes it easier to monitor using Supabase tools like the [Query Performance Dashboard](/dashboard/project/_/advisors/query-performance) and [Log Explorer](/dashboard/project/_/logs/explorer).
      <Admonition type="note" title="password manager">

        For security, consider using a [password generator](https://bitwarden.com/password-generator/) for the Prisma role.

    <Admonition type="note">

      If you're in an [IPv6 environment](https://github.com/orgs/supabase/discussions/27034) or have the IPv4 Add-On, you can use the direct connection string instead of Supavisor in Session mode.

    </Admonition>

    - If you plan on deploying Prisma to a serverless or auto-scaling environment, you'll also need your Supavisor transaction mode string.
    - The string is identical to the session mode string but uses port 6543 at the end.
