The verdict: can you vibe code Supabase?
Build a simple local single-tenant Postgres wrapper or use the real platform, because orchestrating multi-tenant database clusters, WAL change data capture, and RLS gateways is a full engineering platform team's job.
Attempting to clone Supabase as a solo developer is a Sisyphean undertaking. While you can easily write a Next.js app that talks to a single Postgres database, Supabase's core value is its complex control plane: provisioning isolated Postgres containers, running PostgREST for instant API generation, scaling a distributed Elixir Phoenix cluster for real-time WebSocket change data capture, and mapping JWT contexts securely to database session variables. An AI coding agent can scaffold a crude admin dashboard and a single-tenant wrapper, but it cannot manufacture an enterprise-grade BaaS infrastructure out of thin air.
Estimated effort: 6+ months of full-time work
What you can't replicate
- Automated multi-tenant Postgres provisioning, scaling, and Point-in-Time Recovery
- Production-grade distributed Elixir/Phoenix Realtime WAL streaming engine
- Enterprise compliance (SOC2, HIPAA, ISO 27001) and global edge infrastructure network

Build guide
01Project Scaffolding and Control Plane Monorepo
Initialize the Next.js full-stack application structure with TypeScript, Tailwind CSS, and a Docker-compose local orchestration harness.
Create a new Next.js project configured with the App Router, TypeScript, and Tailwind CSS. Setup a monorepo structure with a 'dashboard' frontend directory and a 'control-plane' backend directory. Create a docker-compose.yml file that provisions a local PostgreSQL database, a Redis instance for session management, and a local PostgREST container. Configure environment variables for database connection pooling. Ensure all configuration files are fully written out with strict TypeScript types and zero placeholder comments.02Authentication & Organization Management
Implement authentication for the control plane dashboard using better-auth with secure session handling.
Implement authentication in the Next.js control plane dashboard using better-auth. Configure email/password login, GitHub OAuth login, and session cookies stored securely in the PostgreSQL database. Create database tables for users, organizations, and project memberships using Drizzle ORM or native SQL migration scripts. Add protected layout routes that redirect unauthenticated users to the sign-in page. Verify user token validation logic matches standard JWT specifications.03Project Provisioning and Database Management
Build backend endpoints that programmatically provision isolated database schemas or remote Neon project instances.
Write backend service routines in Node.js that handle project creation requests from authenticated users. When a project is created, generate unique API keys (anon and service_role JWTs), store project metadata in the control plane database, and execute automated DDL migration templates against a designated schema or provisioned Neon database branch. Build a REST endpoint that returns project connection strings and API credentials safely.04Table Editor and SQL Runner Interface
Construct a web-based dashboard interface allowing users to view tables, insert rows, and execute raw SQL queries.
Build a rich dashboard UI in Next.js featuring a Table Editor view and an interactive SQL Editor. The Table Editor must fetch table schemas dynamically, support pagination, filtering, and inline cell editing. The SQL Editor must include a Monaco code editor component, execute raw queries against the active project database via a secure backend proxy, and render tabular JSON results or error states clearly. Implement robust input sanitization and query timeout guards.05Row-Level Security (RLS) Policy Manager
Create a visual interface for constructing and testing PostgreSQL Row-Level Security policies.
Develop a visual RLS Policy Manager interface within the dashboard. Users should be able to view existing policies on tables, toggle RLS status, and create new policies using a guided form builder that generates SQL statements like 'CREATE POLICY ... FOR SELECT USING (...)'. Implement a testing sandbox widget that lets developers simulate queries under different mock JWT claims (e.g. custom auth.uid() values) to verify policy enforcement rules.06Storage and Edge Function Simulators
Integrate S3-compatible file storage bucket management and a mock runtime interface for edge functions.
Incorporate a Storage management section in the dashboard connecting to an S3-compatible object store (like Cloudflare R2 or local MinIO). Implement bucket creation, file upload/download interfaces, and public URL generation. Additionally, create an Edge Functions management tab that lets users deploy simple TypeScript scripts, view execution logs, and invoke functions via HTTP endpoints with custom headers and request payloads.
