How to Install and Use Supabase CLI for Local Development

August 5, 2025 by Jing

The Supabase CLI revolutionizes local development by providing a powerful toolkit for managing PostgreSQL databases, authentication, and edge functions. Unlike traditional database management tools like MySQL Workbench or DBeaver, it offers seamless integration with your development workflow through terminal commands and local emulation. When paired with Chat2DB (opens in a new tab), an AI-powered database management tool, developers gain an intelligent interface for visualizing schemas, generating SQL with natural language, and optimizing queries—making database interactions faster and more intuitive.

Why Supabase CLI Transforms Local Development

The Supabase CLI eliminates the need for manual database setup by automating local environment configuration. Unlike DataGrip or pgAdmin, which focus solely on query execution, Supabase CLI integrates database management with authentication (via GoTrue), real-time subscriptions, and PostgreSQL extensions. Key advantages include:

• Instant Local Stack Emulation: Run Supabase locally with supabase start, including PostgreSQL, Studio, and Auth.
• Type-Safe Development: Auto-generate TypeScript types with supabase gen types.
• Schema Migrations: Version-controlled migrations via supabase migration.

For example, initializing a project is as simple as:

supabase init
supabase start

Prerequisites for Installing Supabase CLI

Before installation, ensure your system meets these requirements:

Install Node.js and npm:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash
nvm install 16

Step-by-Step Supabase CLI Installation

Install the CLI globally via npm:

npm install -g supabase

Verify the installation:

supabase --version

Common troubleshooting:

• Docker not running: Ensure Docker Desktop is active.
• Permission errors: Use sudo or fix npm permissions.

Configuring Your First Local Supabase Project

Initialize a project and link it to your Supabase dashboard:

supabase init
supabase login
supabase link --project-ref your-project-id

Connect Chat2DB (opens in a new tab) to visualize tables. Its AI can generate complex queries from natural language, like:

"Show users who signed up last month and their subscription status"

-- AI-generated query example
SELECT users.id, users.email, subscriptions.status 
FROM users 
JOIN subscriptions ON users.id = subscriptions.user_id 
WHERE users.created_at >= NOW() - INTERVAL '1 month';

Essential Supabase CLI Commands

• Start/stop the local stack:

  supabase start
  supabase stop
• Create and apply migrations:

  supabase migration new create_users_table
  supabase db reset

Advanced Workflows: RLS and Edge Functions

Test Row-Level Security (RLS) policies locally:

-- Enable RLS on a table
ALTER TABLE profiles ENABLE ROW LEVEL SECURITY;
CREATE POLICY "User can edit own profile" ON profiles
  USING (auth.uid() = user_id);

Deploy an edge function:

supabase functions deploy hello-world

Boosting Productivity with Chat2DB

Chat2DB (opens in a new tab) enhances Supabase CLI by:

• AI-Powered SQL Generation: Convert plain English to optimized queries.
• Visual Schema Designer: Drag-and-drop table relationships.
• Cross-Platform Support: Windows, macOS, and Linux.

For example, ask Chat2DB:

"Optimize this query for performance"

-- Before optimization
SELECT * FROM orders WHERE created_at > '2023-01-01';
 
-- After AI optimization
SELECT id, total FROM orders WHERE created_at > '2023-01-01' ORDER BY created_at DESC LIMIT 100;

Debugging and Optimization Tips

• Monitor logs:

  supabase logs
• Tune PostgreSQL:

  ALTER SYSTEM SET shared_buffers = '4GB';

FAQ

1. Can I use Supabase CLI without Docker?
   No, Docker is required for local PostgreSQL emulation.

2. How does Chat2DB compare to DBeaver?
   Chat2DB uses AI for query generation and optimization, unlike manual tools.

3. Is Supabase CLI compatible with Windows?
   Yes, but WSL2 is recommended for best performance.

4. How to sync local schema with production?
   Use supabase db pull to fetch remote schema changes.

5. Does Chat2DB support real-time collaboration?
   Not yet, but its AI features streamline solo development.
