## 🚀 Quick Start

> [!TIP]
> **Prefer a visual configurator?** Use the [Web Configurator](https://oss.vstorm.co/projects/full-stack-ai-agent-template/configurator/) to configure your project in the browser and download a ZIP — no CLI installation needed.

### Installation

```bash
# pip
pip install fastapi-fullstack

# uv (recommended)
uv tool install fastapi-fullstack

# pipx
pipx install fastapi-fullstack
```

### Create Your Project

```bash
# Interactive wizard (recommended — runs by default)
fastapi-fullstack

# Quick mode with options
fastapi-fullstack create my_ai_app \
  --database postgresql \
  --frontend nextjs

# Use presets for common setups
fastapi-fullstack create my_ai_app --preset production   # Full production setup
fastapi-fullstack create my_ai_app --preset ai-agent     # AI agent with streaming

# Minimal project (no extras)
fastapi-fullstack create my_ai_app --minimal
```

### Start Development (Docker — recommended)

The fastest way to get running — 2 commands:

```bash
cd my_ai_app
make docker-up       # Start backend + database + migrations + admin user
make docker-frontend # Start frontend
```

**Access:**

- API: <http://localhost:8000>
- Docs: <http://localhost:8000/docs>
- Admin Panel: <http://localhost:8000/admin>
- Frontend: <http://localhost:3000>

> [!TIP]
> That's it. Docker handles database setup, migrations, and admin user creation automatically.

<details>
<summary><b>Manual setup (without Docker)</b></summary>

#### 1. Install dependencies

```bash
cd my_ai_app
make install
```

> [!NOTE]
> **Windows Users:** The `make` command requires GNU Make which is not available by default on Windows.
> Install via [Chocolatey](https://chocolatey.org/) (`choco install make`), use WSL, or run raw commands manually.
> Each generated project includes a "Manual Commands Reference" section in its README with all commands.

#### 2. Start the database

```bash
# PostgreSQL (with Docker)
make docker-db
```

#### 3. Create and apply database migrations

> [!WARNING]
> Both commands are required! `db-migrate` creates the migration file, `db-upgrade` applies it to the database.

```bash
# Create initial migration (REQUIRED first time)
make db-migrate
# Enter message: "Initial migration"

# Apply migrations to create tables
make db-upgrade
```

#### 4. Create admin user

```bash
make create-admin
# Enter email and password when prompted
```

#### 5. Start the backend

```bash
make run
```

#### 6. Start the frontend (new terminal)

```bash
cd frontend
bun install
bun dev
```

**Access:**

- API: <http://localhost:8000>
- Docs: <http://localhost:8000/docs>
- Admin Panel: <http://localhost:8000/admin> (login with admin user)
- Frontend: <http://localhost:3000>

</details>

### Using the Project CLI

Each generated project has a CLI named after your `project_slug`. For example, if you created `my_ai_app`:

```bash
cd backend

# The CLI command is: uv run <project_slug> <command>
uv run my_ai_app server run --reload     # Start dev server
uv run my_ai_app db migrate -m "message" # Create migration
uv run my_ai_app db upgrade              # Apply migrations
uv run my_ai_app user create-admin       # Create admin user
```

Use `make help` to see all available Makefile shortcuts.

```bash
# PydanticAI with OpenAI (default)
fastapi-fullstack create my_app --ai-framework pydantic_ai

# LangGraph with Anthropic
fastapi-fullstack create my_app --ai-framework langgraph --llm-provider anthropic

# CrewAI with Google Gemini
fastapi-fullstack create my_app --ai-framework crewai --llm-provider google

# DeepAgents with OpenAI
fastapi-fullstack create my_app --ai-framework deepagents

# With RAG enabled
fastapi-fullstack create my_app --rag --database postgresql --task-queue celery
```

### Supported Combinations

| Framework | OpenAI | Anthropic | Gemini | OpenRouter |
|-----------|:------:|:---------:|:------:|:----------:|
| **PydanticAI** | ✓ | ✓ | ✓ | ✓ |
| **PydanticDeep** | ✓ | ✓ | ✓ | - |
| **LangChain** | ✓ | ✓ | ✓ | - |
| **LangGraph** | ✓ | ✓ | ✓ | - |
| **CrewAI** | ✓ | ✓ | ✓ | - |
| **DeepAgents** | ✓ | ✓ | ✓ | - |

### PydanticAI Integration

Type-safe agents with full dependency injection:

```python
# app/agents/assistant.py
from pydantic_ai import Agent, RunContext

@dataclass
class Deps:
    user_id: str | None = None
    db: AsyncSession | None = None

agent = Agent[Deps, str](
    model="openai:gpt-4o-mini",
    system_prompt="You are a helpful assistant.",
)

@agent.tool
async def search_database(ctx: RunContext[Deps], query: str) -> list[dict]:
    """Search the database for relevant information."""
    # Access user context and database via ctx.deps
    ...
```

### LangChain Integration

Flexible agents with LangGraph:

```python
# app/agents/langchain_assistant.py
from langchain.tools import tool
from langgraph.prebuilt import create_react_agent

@tool
def search_database(query: str) -> list[dict]:
    """Search the database for relevant information."""
    ...

agent = create_react_agent(
    model=ChatOpenAI(model="gpt-4o-mini"),
    tools=[search_database],
    prompt="You are a helpful assistant.",
)
```

### WebSocket Streaming

Both frameworks use the same WebSocket endpoint with real-time streaming:

```python
@router.websocket("/ws")
async def agent_ws(websocket: WebSocket):
    await websocket.accept()

    # Works with both PydanticAI and LangChain
    async for event in agent.stream(user_input):
        await websocket.send_json({
            "type": "text_delta",
            "content": event.content
        })
```

### Observability

Each framework has its own observability solution:

| Framework | Observability | Dashboard |
|-----------|--------------|-----------|
| **PydanticAI** | [Logfire](https://logfire.pydantic.dev) | Agent runs, tool calls, token usage |
| **LangChain** | [LangSmith](https://smith.langchain.com) | Traces, feedback, datasets |

See [AI Agent Documentation](https://github.com/vstorm-co/full-stack-ai-agent-template/blob/main/docs/ai-agent.md) for more.

## 📊 Observability

### Logfire (for PydanticAI)

[Logfire](https://logfire.pydantic.dev) provides complete observability for your application - from AI agents to database queries. Built by the Pydantic team, it offers first-class support for the entire Python ecosystem.

```mermaid
graph LR
    subgraph Your App
        API[FastAPI]
        Agent[PydanticAI]
        DB[(Database)]
        Cache[(Redis)]
        Queue[Celery/Taskiq]
        HTTP[HTTPX]
    end

    subgraph Logfire
        Traces[Traces]
        Metrics[Metrics]
        Logs[Logs]
    end

    API --> Traces
    Agent --> Traces
    DB --> Traces
    Cache --> Traces
    Queue --> Traces
    HTTP --> Traces
```

| Component | What You See |
|-----------|-------------|
| **PydanticAI** | Agent runs, tool calls, LLM requests, token usage, streaming events |
| **FastAPI** | Request/response traces, latency, status codes, route performance |
| **PostgreSQL/MongoDB** | Query execution time, slow queries, connection pool stats |
| **Redis** | Cache hits/misses, command latency, key patterns |
| **Celery/Taskiq** | Task execution, queue depth, worker performance |
| **HTTPX** | External API calls, response times, error rates |

### LangSmith (for LangChain)

[LangSmith](https://smith.langchain.com) provides observability specifically designed for LangChain applications:

| Feature | Description |
|---------|-------------|
| **Traces** | Full execution traces for agent runs and chains |
| **Feedback** | Collect user feedback on agent responses |
| **Datasets** | Build evaluation datasets from production data |
| **Monitoring** | Track latency, errors, and token usage |

LangSmith is automatically configured when you choose LangChain:

```bash
# .env
LANGCHAIN_TRACING_V2=true
LANGCHAIN_API_KEY=your-api-key
LANGCHAIN_PROJECT=my_project
```

### Configuration

Enable Logfire and select which components to instrument:

```bash
fastapi-fullstack new
# ✓ Enable Logfire observability
#   ✓ Instrument FastAPI
#   ✓ Instrument Database
#   ✓ Instrument Redis
#   ✓ Instrument Celery
#   ✓ Instrument HTTPX
```

### Usage

```python
# Automatic instrumentation in app/main.py
import logfire

logfire.configure()
logfire.instrument_fastapi(app)
logfire.instrument_asyncpg()
logfire.instrument_redis()
logfire.instrument_httpx()
```

```python
# Manual spans for custom logic
with logfire.span("process_order", order_id=order.id):
    await validate_order(order)
    await charge_payment(order)
    await send_confirmation(order)
```

For more details, see [Logfire Documentation](https://logfire.pydantic.dev/docs/integrations/).

## 🛠️ Django-style CLI

Each generated project includes a powerful CLI inspired by Django's management commands:

### Built-in Commands

```bash
# Server
my_app server run --reload
my_app server routes

# Database (Alembic wrapper)
my_app db init
my_app db migrate -m "Add users"
my_app db upgrade

# Users
my_app user create --email admin@example.com --superuser
my_app user list
```

### Custom Commands

Create your own commands with auto-discovery:

```python
# app/commands/seed.py
from app.commands import command, success, error
import click

@command("seed", help="Seed database with test data")
@click.option("--count", "-c", default=10, type=int)
@click.option("--dry-run", is_flag=True)
def seed_database(count: int, dry_run: bool):
    """Seed the database with sample data."""
    if dry_run:
        info(f"[DRY RUN] Would create {count} records")
        return

    # Your logic here
    success(f"Created {count} records!")
```

Commands are **automatically discovered** from `app/commands/` - just create a file and use the `@command` decorator.

```bash
my_app cmd seed --count 100
my_app cmd seed --dry-run
```

## 🔄 Comparison

### vs. Manual Setup

Setting up a production AI agent stack manually means wiring together 10+ tools yourself:

```bash
# Without this template, you'd need to manually:
# 1. Set up FastAPI project structure
# 2. Configure SQLAlchemy + Alembic migrations
# 3. Implement JWT auth with refresh tokens
# 4. Build WebSocket streaming for AI responses
# 5. Integrate PydanticAI/LangChain with tool calling
# 6. Set up RAG pipeline (parsing, chunking, embedding, vector store)
# 7. Configure Celery + Redis for background tasks
# 8. Build Next.js frontend with auth and chat UI
# 9. Write Docker Compose for all services
# 10. Add observability, rate limiting, admin panel...

# With this template:
pip install fastapi-fullstack
fastapi-fullstack
# Done. All of the above, configured and working.
```

## ❓ FAQ

<details>
<summary><b>How is this different from full-stack-fastapi-template?</b></summary>

[full-stack-fastapi-template](https://github.com/fastapi/full-stack-fastapi-template) by @tiangolo is a great starting point for FastAPI projects, but it focuses on traditional web apps. This template is purpose-built for **AI/LLM applications** — it adds AI agents (5 frameworks), RAG with 4 vector stores, WebSocket streaming, conversation persistence, LLM observability, and a Next.js chat UI out of the box.

</details>

<details>
<summary><b>Can I use this without AI/LLM features?</b></summary>

Yes. The AI agent and RAG modules are optional. You can use this as a pure FastAPI + Next.js template with auth, admin panel, background tasks, and all other infrastructure — just skip the AI framework selection during setup.

</details>

<details>
<summary><b>What Python and Node.js versions are required?</b></summary>

Python 3.11+ and Node.js 18+ (for the Next.js frontend). We recommend using [uv](https://docs.astral.sh/uv/) for Python and [bun](https://bun.sh) for the frontend.

</details>

<details>
<summary><b>Can I add integrations after project generation?</b></summary>

The generated project is plain code — no lock-in or runtime dependency on the generator. You can add, remove, or modify any integration manually. The template just gives you a well-structured starting point.

</details>

<details>
<summary><b>Can I use a different LLM provider than the one I selected?</b></summary>

Yes. The LLM provider is configured via environment variables (`AI_MODEL`, `OPENAI_API_KEY`, etc.). You can switch providers by changing the `.env` file and the model name — no code changes needed for PydanticAI (which supports all providers natively).

</details>
