The key design decision is not a special AI API: it is deciding which listings are public, who can submit or edit them, and how moderators approve changes.
This guide walks through a practical implementation sequence, from scaffolding through database policies, search, security, and deployment. The exact schema, moderation rules, and search approach are product choices—not requirements imposed by Next.js or Supabase.

1. Define the directory workflow and listing data
Before creating tables, map how a tool moves through your directory. A straightforward workflow is: a visitor browses published listings, a signed-in user submits a tool, and an administrator reviews it before publication. Decide whether submitters may edit a listing after submission and how updates to an already-published tool are reviewed.
Choose the fields readers need
A useful starting listing can include a name, unique slug, short summary, category, tags, pricing label, canonical website URL, and publication status. Add fields only when they support a reader task or an operational need. For example, a submission may also need an owner user ID and timestamps for creation and review.
#1 Best Overall
Keep public-facing listing data conceptually separate from moderation notes or other private information. That separation makes it easier to grant public access to the catalog without exposing draft content or internal fields.
Set the roles before setting permissions
- Public visitors: read published listings.
- Submitters: create submissions and, if your workflow allows it, edit their own entries.
- Moderators or administrators: review submissions, publish or reject them, and correct listings.
These roles are an implementation model, not a framework-mandated schema. Your database policies should match the workflow you actually intend to operate.
2. Scaffold Next.js and Supabase
Supabase’s official Next.js quickstart currently offers a preconfigured template. Create the project with:

npx create-next-app@latest my-app -e with-supabaseThe template is described as including cookie-based authentication, TypeScript, and Tailwind CSS. It installs @supabase/supabase-js and @supabase/ssr, with separate utilities for browser and server clients. Follow the setup instructions in Supabase’s Next.js quickstart to configure the project URL and publishable key through environment variables; do not commit secrets or credentials to source control.
The App Router organizes application routes and uses React features such as Server Components and Client Components. Consult the Next.js App Router documentation for the routing model and current conventions.
3. Model listings in Postgres and protect them with RLS
Use database permissions and row-level security (RLS) to enforce which records each role can access. The Supabase quickstart demonstrates granting the anon role only select access to a sample table, enabling RLS, and defining a public-read policy. For a directory, adapt that pattern so anonymous readers can select published listings—not every row in a submissions table.

Match each operation to a role
| Operation | Intended access | Policy design goal |
|---|---|---|
| Read published listings | Public visitors | Allow reads only for records whose publication state is public. |
| Create a submission | Signed-in submitter | Allow the required insert, and derive ownership from the authenticated user rather than a client-supplied owner ID. |
| Edit a submission | Submitter, if supported | Limit changes to records owned by that user and prevent unauthorized changes to review or publication fields. |
| Review or publish | Moderator or administrator | Restrict status changes and moderation actions to an authorized role. |
The table describes policy goals, not ready-to-run SQL: exact expressions depend on your schema and how you represent roles and ownership. Supabase explicitly cautions that its sample policies are illustrative, not production policies for real user data. See the quickstart’s SQL and RLS guidance before adapting policies.

4. Query pages with the right Supabase client
Use the server Supabase client in Server Components, Server Actions, and Route Handlers. Use the browser client in Client Components that need browser-side access. The SSR guide separates these contexts because authentication state is stored in cookies; use its current setup rather than sharing one client utility everywhere. See Supabase’s SSR client guide for Next.js.
Server Components cannot write cookies. Supabase’s current integration guidance uses a Proxy to refresh expired auth tokens; it specifies proxy.ts for Next.js 16 and middleware.ts for Next.js 15 and earlier. Check the version actually installed in your project before choosing the file convention, since framework integrations can change.
Build the directory around server-rendered data
A practical first version can render the listing index and individual detail pages from server-side queries, passing only the data each component needs. Keep interactive controls—such as filter controls or a submission form—in Client Components only where browser interaction requires them. This is an architectural choice for the app, not a claim that the stack requires one rendering strategy.
5. Add search and discovery that fit the catalog
Start with filters your schema can support directly: category, pricing label, tags, or use case. Make the selected filters part of the page’s query state so readers can navigate to or share a filtered view. Add a text search over fields such as name and summary if that addresses the basic discovery need.
There is no single directory search or AI-ranking implementation prescribed by Next.js or Supabase in the cited guides. Choose more advanced search only when catalog size and user needs justify it; do not add AI ranking merely because the listings are AI tools. If you later rank results, document the signals, make sponsored or editorial placement distinctions clear, and ensure the ordering does not silently override useful filters.
6. Secure every submission and moderation mutation
Server Actions can power forms for submitting, editing, and moderating listings. But they are network-reachable mutation entry points: Next.js documents that Server Functions are invoked through network requests and that Server Actions can be called by direct POST requests, not only through the visible interface. A hidden button or protected-looking page is not an authorization boundary.
Next.js states: “Treat Server Actions with the same security considerations as public-facing API endpoints, and verify if the user is allowed to perform a mutation.” Apply that rule to every action and Route Handler. The relevant guidance is in Mutating Data and Authentication.
Validate, authorize, then change data
- Validate input on the server. Check required fields and bounds; validate slugs, URLs, tags, and descriptions rather than trusting browser controls.
- Authenticate the caller. Establish who is making the request using the server-side auth context.
- Authorize the exact operation. Check that the caller may submit, edit that record, or perform the relevant moderation action.
- Verify ownership and protected fields. Do not trust a client-provided owner ID or role. Prevent submitters from granting themselves moderator status or publishing their own entry if that is not part of the policy.
- Return only necessary data. Avoid sending internal moderation fields or other private data back to the browser.
Keep data access and authorization logic in an isolated server-side layer so pages, actions, and handlers use consistent checks. Next.js details these principles in its Data Security guide.

Deployment depends on whether the directory needs dynamic server rendering, Server Actions, Route Handlers, authentication refresh, or other runtime features. In the Next.js deployment documentation, last updated August 6, 2026, Node.js server and Docker deployments support all Next.js features; static export has limited feature support, and adapter support varies. Vercel is listed among verified adapters, which is compatibility information rather than a price or performance recommendation.
| Deployment approach | Documented feature support | What to assess |
|---|---|---|
| Node.js server | All Next.js features | Operate a server runtime and configure the app’s environment. |
| Docker | All Next.js features | Build and operate a containerized runtime. |
| Static export | Limited feature support | Use only if the app’s required features can run without unsupported server behavior. |
| Platform adapter | Varies by adapter | Verify support for the specific features your app uses; the docs list Vercel as a verified adapter. |
Do not choose static export on the assumption that all App Router features will work without a server. Check the official deployment matrix against your actual use of rendering, actions, handlers, and caching, then configure Supabase values in the deployment environment rather than in committed files.
Quick Recap
8. A practical build order
- Write down the visitor, submitter, and moderator workflows, including what happens to edits after publication.
- Define the listing fields and decide which information is public versus internal.
- Scaffold with the Supabase template and configure environment variables.
- Create tables, grants, and RLS policies that implement the workflow’s least-privilege rules.
- Build server-rendered listing and detail pages, then add the browser interactions the interface needs.
- Add filters and basic text search; evaluate more advanced search only against actual discovery requirements.
- Implement submission and moderation actions with server-side validation, authentication, authorization, and ownership checks.
- Select a deployment mode after verifying support for every runtime feature the app uses.
