Webflow Cloud lets you store and manage structured data using SQLite, a lightweight, serverless database engine. This managed solution gives you familiar SQL syntax, secure access at the edge, and seamless integration with modern frameworks, without the need to manage servers or credentials.

Webflow Cloud handles database provisioning, security, and scaling, so you can focus on building features, not infrastructure.

Key benefits

• Familiar SQL syntax - Use standard SQL for queries and data manipulation.
• Automatic authentication - No credential management, secure by default.
• Flexible multi-database architecture - Create thousands of small, isolated databases per account, ideal for multi-tenant SaaS or per-user data isolation.
• ORM and driver compatibility - Works with popular tools like Prisma and Drizzle for type-safe queries and schema management.
• Data security - All data is encrypted at rest and in transit.
• Automatic daily backups - Webflow Cloud manages backups for you.

Add SQLite to your app

Create a SQLite database by declaring bindings in your wrangler.json file in the root of your app. When it is deployed, Webflow Cloud automatically connects your app to a managed SQLite instance.

{
2
"d1_databases": [
3
    {
4
    "binding": "DB",
5
    "database_name": "MY_DATABASE",
6
    "database_id": "1234567890", // Replace after deployment
7
    "migrations_dir": "./migrations" // Specify the directory for your migrations
8
    }

Work with a SQLite database

Access the binding

Webflow Cloud exposes your SQLite database to your app as an environment variable, known as a binding. This lets you interact with your database directly from your application code.

Always access the environment variable in your app’s runtime environment. This variable exposes methods from the Cloudflare Workers Bindings API, allowing you to run SQL statements directly from your code.

For full details on available methods and advanced usage, see the Cloudflare D1 Bindings API documentation.

1
import type { APIRoute } from "astro";
2
import type { D1Database } from "@cloudflare/workers-types";
3
4
// 👀 GET request to create users table and insert users
5
export const GET: APIRoute = async ({ request, locals }) => {
6
7
  // Access the runtime environment and get the database binding
8
  const env = (locals as any).runtime.env;
9
  const db = env.DB as D1Database;
10
11
  // Query users using the binding
12
  const { results } = await DB.prepare("SELECT * FROM users_table;").all();
13
14
  // Return the results
15
  return new Response(JSON.stringify(results), {
16
    headers: { "Content-Type": "application/json" },
17
    });
18
};

Manage schema and migrations

Webflow Cloud uses migrations to manage changes to your SQLite database schema over time. Migrations are versioned .sql files that describe how your database structure should evolve as your app changes.

When you declare your SQLite binding in wrangler.json, use the migrations_dir property to specify the directory containing your migration files. Webflow Cloud will automatically apply those migrations to your database when you deploy your app.

Additionally, Webflow Cloud supports popular ORM libraries like Drizzle ORM and Prisma-Edge for type-safe queries and schema management. See more on using an ORM with Webflow Cloud.

Key concepts

• Migration files: Place .sql files in the migrations directory you defined in wrangler.json. Each file should contain SQL statements that create or modify tables, indexes, or other schema elements.
• Automatic application: When you deploy your app, Webflow Cloud automatically applies any new migration files to your database. This keeps your schema up to date with your codebase.
• Additive changes only: Migrations must be additive. You can’t “undo” a migration by editing or deleting a migration file in your directory. To change your schema, always add a new migration file with the required SQL.

Example migration file:

1
CREATE TABLE IF NOT EXISTS users_table (
2
  id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,
3
  name TEXT NOT NULL,
4
  age INTEGER NOT NULL,
5
  email TEXT NOT NULL
6
);

Best practices

• Use clear, sequential filenames (for example, 001_init.sql, 002_add_email_index.sql).
• Never edit or remove existing migration files after they’ve been deployed.
• Test migrations locally before deploying to production.

ORM support for SQLite

Webflow Cloud’s SQLite databases support edge-compatible ORM libraries, letting you write type-safe queries and manage schema changes with familiar tools. Drizzle ORM and Prisma-Edge are popular choices for seamless integration with Webflow Cloud.

When using an ORM, you’ll typically add a dedicated folder (such as /migrations or /drizzle) to your app to store migration files and schema definitions. Be sure to specify this directory in your wrangler.json using the migrations_dir property for your SQLite binding.

1
{
2
  "d1_databases": [
3
      {
4
          "binding": "DB",
5
          "database_name": "MY_DATABASE",
6
          "database_id": "1234567890",
7
          "migrations_dir": "drizzle"
8
      }
9
  ]
10
}

Local development with SQLite

You can use Cloudflare’s Wrangler CLI to develop and test your SQLite database locally before deploying to Webflow Cloud.

When you run your app locally, Wrangler creates a SQLite database in your .wrangler directory. This local database lets you test SQL statements and migrations in a safe environment. Use Wrangler CLI commands, either directly in your terminal or as scripts in package.json to run your app and execute SQL statements or files on your local database.

You can use Cloudflare’s Wrangler CLI to:

• Run your app locally
  

  AstroNext.js

  $
  npx wrangler dev

  This command starts your app locally, simulating the Workers runtime with your declared bindings, and creates a local SQLite database in your .wrangler directory.

• Apply migrations to your local database:

  $
  wrangler d1 migrations apply <DATABASE_NAME> --local

  Updates your local SQLite schema with any new migration files in the migrations directory defined in your wrangler.json file. Replace <DATABASE_NAME> with the name of your binding.

• Execute SQL statements or files on your local database:

  $
  wrangler d1 execute <DATABASE_NAME> --local --command "<SQL_STATEMENT>"
  $
  wrangler d1 execute <DATABASE_NAME> --local --file ./migrations/001_init.sql

  Run ad-hoc queries or apply SQL files directly to your local database.

  These commands won’t affect your remote database.
