• Modern Stack: Next.js 16 + React 19, FastAPI, Flutter 3.38, TailwindCSS v4
• Type Safety: Full type support with TypeScript, Pydantic, and Dart
• Authentication: OAuth with better-auth (Google, GitHub, Facebook)
• Internationalization: next-intl (web), Flutter ARB (mobile), shared i18n package
• Auto-generated API Clients: Orval (web), swagger_parser (mobile)
• Infrastructure as Code: Terraform + GCP (Cloud Run, Cloud SQL, Cloud Storage)
• CI/CD: GitHub Actions + Workload Identity Federation (keyless deployment)
• AI Agent Support: Guidelines for AI coding agents (Gemini, Claude, etc.)
• mise Monorepo: mise-based task management and unified tool versions

| Agent | Role |

|-------|------|

| PM Agent | Analyzes requirements, defines API contracts, creates prioritized task breakdown |

| Domain Agents | Frontend, Backend, Mobile, Infra agents execute tasks in parallel by priority |

| QA Agent | Reviews security (OWASP), performance, accessibility (WCAG 2.1 AA) |

Choose one of the following methods to start with this template:

```bash

# Create from CLI

bun create fullstack-starter my-app

# or

npm create fullstack-starter my-app

```

Or use GitHub:

1. Click [Use this template](https://github.com/first-fluke/fullstack-starter/generate) to create a new repository
2. Or [Fork](https://github.com/first-fluke/fullstack-starter/fork) this repository

Prerequisites

Required for all platforms:

• [mise](https://mise.jdx.dev/) - Runtime version manager
• [Docker](https://www.docker.com/) or [Podman Desktop](https://podman-desktop.io/downloads) - Local infrastructure

For mobile development (iOS/Android):

• [Xcode](https://apps.apple.com/app/xcode/id497799835) - Includes iOS Simulator (macOS only)
• [Android Studio](https://developer.android.com/studio) - Includes Android SDK and emulator

Optional:

• [Terraform](https://www.terraform.io/) - Cloud infrastructure

1. Install Runtimes

```bash

# Install mise (if not installed)

curl https://mise.run | sh

# Install all runtimes (Node 24, Python 3.12, Flutter 3, bun, uv, Terraform)

mise install

```

2. Install Dependencies

```bash

# Install all dependencies at once

mise run install

```

3. Start Local Infrastructure

```bash

mise infra:up

```

This starts:

• PostgreSQL (5432)
• Redis (6379)
• MinIO (9000, 9001)

4. Run Database Migrations

```bash

mise db:migrate

```

5. Start Development Servers

```bash

# Start API and Web services (recommended for web development)

mise dev:web

# Start API and Mobile services (recommended for mobile development)

mise dev:mobile

# Or start all services

mise dev

```

```
