A full-stack app in one file

A Postgres-compatible database, an API, and a website behind a firewall:

import * as anvil from '@anvil-cloud/sdk';

export default new anvil.App({
  run(ctx) {
    const db = new anvil.aws.DSQL('db', {
      schemas: [{
        name: 'shop',
        roles: [{ name: 'app_role', grants: ['SELECT', 'INSERT', 'UPDATE'] }],
        tables: [{
          name: 'orders',
          columns: [
            { name: 'id', type: 'uuid', notNull: true },
            { name: 'total', type: 'numeric', precision: 10, scale: 2 },
          ],
          primaryKey: ['id'],
        }],
      }],
    });

    const handler = new anvil.aws.Lambda('orders', {
      runtime: 'nodejs22.x',
      entry: 'functions/orders.ts',
      handler: 'handler',
      environment: { DSQL_ENDPOINT: db.endpoint },
    });
    db.grantConnect(handler, { schemas: [{ schema: 'shop', roleName: 'app_role' }] });

    const api = new anvil.aws.HttpApi('api', {
      routes: [{ method: 'GET', path: '/orders', consumer: { lambda: { arn: handler.arn } } }],
    });

    const waf = new anvil.aws.Waf('edge');
    new anvil.aws.SvelteKitSite('web', {
      path: 'web',
      runtimeEnvironment: { API_URL: api.url },
      waf: { arn: waf.arn },
    });
  },
});

What anvil deploy gives you without being asked:

• 🗄️ Database: schema, tables, and roles created from code. The Lambda connects as app_role with a short-lived IAM token, so there are no passwords and no admin credentials in your pipeline.
• 🔐 Permissions: least-privilege IAM written for you. The Lambda can connect to this cluster and nothing else.
• 🚦 API: rate limiting on every route, access logs kept for a year, and CORS off until you configure it (* is rejected).
• 🛡️ Website: CloudFront with AWS managed WAF rules, a server Lambda reachable only through CloudFront, and HSTS, nosniff, and frame-protection headers on every response.
• 🏷️ Tagging: every resource tagged with its project and stage, plus any tags you add, so costs are traceable from day one.

Each default is a starting point. You can opt out of or override any of them, which beats starting from nothing and hoping you remembered everything. The defaults are aligned to SOC 2 and ISO 27001 controls: that isn't a certification, but it does the heavy lifting when you're working toward one.

Comparing Anvil

The same image upload stack, built five ways.

Framework	Infra lines	Components	Manual permissions	Deploys with
Anvil	58	4	1	Pulumi engine
CDK	74 (1.3×)	7 (1.8×)	1 (1.0×)	CloudFormation
CloudFormation	134 (2.3×)	12 (3.0×)	4 (4.0×)	CloudFormation
Pulumi	150 (2.6×)	17 (4.3×)	6 (6.0×)	Pulumi engine
Terraform	194 (3.3×)	17 (4.3×)	7 (7.0×)	Terraform engine

See all five implementations side by side at anvilcloud.dev.

Permissions without writing IAM

Resources grant each other access. Anvil writes the least-privilege IAM policy, scoped to the actions and paths you ask for:

run(ctx) {
  const uploads = new anvil.aws.Bucket('uploads');

  const resize = new anvil.aws.Lambda('resize', {
    runtime: 'nodejs22.x',
    entry: 'functions/resize/index.ts',
    handler: 'handler',
  });

  // Read-only, and objects only under incoming/
  uploads.grantRead(resize, ['incoming/*']);
},

The policy Anvil attaches to resize

{
  "Effect": "Allow",
  "Action": ["s3:GetObject", "s3:ListBucket"],
  "Resource": [
    "arn:aws:s3:::uploads-…",
    "arn:aws:s3:::uploads-…/incoming/*"
  ]
}

No ARNs to wire, no s3:* policies left over from debugging.

Compliance scanning built in

Add one block to your app and Anvil scans what you deployed against the frameworks you're working toward, using Prowler:

export default new anvil.App({
  compliance: {
    frameworks: ['soc2', 'iso27001', 'cis'],
    schedule: 'daily',
    scanOnDeploy: true,
  },
  run(ctx) {
    // ...
  },
});

anvil compliance scan        # scan this app's resources now
anvil compliance status      # latest results
anvil compliance dashboard   # open a local dashboard of findings

Supported frameworks include SOC 2, ISO 27001, CIS, NIST 800-53, PCI DSS, HIPAA, GDPR, NIS2, DORA, FedRAMP, and the ASD Essential Eight. Results stay in your own AWS account.

Install Anvil

macOS / Linux

curl -fsSL https://raw.githubusercontent.com/anvil-cloud/anvil/master/install.sh | sh

Windows (PowerShell)

irm https://raw.githubusercontent.com/anvil-cloud/anvil/master/install.ps1 | iex

Installs anvil and the provider to /usr/local/bin. Works on Apple Silicon and Intel.

Quickstart

anvil init --name my-app --lang ts
cd my-app
npm install

Declare a bucket in anvil.config.ts:

import * as anvil from '@anvil-cloud/sdk';

export default new anvil.App({
  defaults: {
    tags: {
      project: 'my-app',
      costCenter: 'platform-eng',
    },
  },
  run(ctx) {
    const uploads = new anvil.aws.Bucket('uploads');

    ctx.export('bucketName', uploads.bucketName);
  },
});

The bucket is private and encrypted without any extra arguments. Preview, deploy, and tear down:

anvil preview
anvil deploy
anvil destroy --stage <stage>

Every deploy goes to a stage. Without --stage it's your active stage (anvil stage set <name>), or your username if none is set, so each developer gets their own copy. destroy always needs --stage spelled out, so you can't tear down the wrong one by accident.

destroy keeps protected resources that hold data (DSQL clusters, DynamoDB tables, Cognito user pools). Add --force to delete them too.

See the Quickstart for Python and Go.

Three SDKs, one engine

Every component behaves identically across all three SDKs.

Python	pip install anvil-cloud	Python 3.9+
Go	go get github.com/anvil-cloud/anvil/sdk/go/anvil	Go 1.25+
