Tech stack for an internal admin tool (2026)

Support team admin panel, designed by StackPrism from one sentence: 6 components, a reason for each, and the live checks that watch them.

The stack

  • Next.js
  • Node.js
  • Clerk
  • PostgreSQL
  • Stripe
  • Sentry

The idea someone typed
“An internal admin tool for our support team: look up customers, refund orders and edit accounts in our existing Postgres database, with Google Workspace sign-in, role-based permissions and a log of every change.”

Make it yours. Open this stack in the editor to check its health, harden it and hand it to your coding agent. No sign-up, nothing to generate.

Select a component to see what it does and what it connects to, or pick one above to see what breaks if it goes down. Pinch or use the buttons to zoom.

Why this stack

Support staff sign in through Clerk with their company Google Workspace accounts and land in a Next.js admin dashboard on Vercel. Every action goes through a small Node.js API rather than straight from the browser to the database: the API checks the person’s role, reads and edits customers in the existing PostgreSQL database and issues refunds through Stripe. Keeping every write in one API also gives one place to record who changed what. Sentry reports errors.

Why each piece

All 6 components on the diagram: what each one does, what it talks to, and what stops if it goes down.

  1. Next.js Admin Dashboard

    In Vercel

    Support admin UI. Calls Node.js API and Sentry (errors). Called by Clerk (sign in).

    If it goes down, 1 of 5 components stops working.

  2. Node.js API

    In Vercel

    Admin policy API. Calls PostgreSQL (queries), Stripe (refunds) and Sentry (errors). Called by Next.js Admin Dashboard.

    If it goes down, 2 of 5 components stop working.

  3. Clerk

    SSO and sessions. Calls Next.js Admin Dashboard (sign in).

    Nothing else on the diagram depends on it.

  4. PostgreSQL

    System of record. Called by Node.js API (queries).

    If it goes down, 3 of 5 components stop working.

  5. Stripe

    In External Services

    Refund processor. Called by Node.js API (refunds).

    If it goes down, 1 of 5 components degrades.

  6. Sentry

    In External Services

    Error tracking. Called by Next.js Admin Dashboard (errors) and Node.js API (errors).

    If it goes down, 2 of 5 components degrade.

When this stack fits

  • You already have the database, and the tool only reads and edits it.
  • People need different powers, such as looking up versus refunding, so permissions live in an API, not in the browser.
  • A small group of internal users who already have company Google accounts.

When to pick something else

  • You need it this week and the screens are standard tables and forms: an internal-tool builder such as Retool connects to the same PostgreSQL with less code.
  • Support also needs data from other systems, such as email or a CRM: those connections aren’t on this diagram.

What you need to build this

6 components across 6 areas of the stack.
