Iterate over your agents 10x faster. AI engineers use PySpur to iterate over AI agents visually without reinventing the wheel.

# 🕸️ Why PySpur?

## Problem: It takes a 1,000 tiny paper cuts to make AI reliable

AI engineers today face three problems of building agents:

* **Prompt Hell**: Hours of prompt tweaking and trial-and-error frustration.
* **Workflow Blindspots**: Lack of visibility into step interactions causing hidden failures and confusion.
* **Terminal Testing Nightmare** Squinting at raw outputs and manually parsing JSON.

We've been there ourselves, too. We launched a graphic design agent early 2024 and quickly reached thousands of users, yet, struggled with the lack of its reliability and existing debugging tools.

## Solution: A playground for agents that saves time

### Step 1: Define Test Cases

https://github.com/user-attachments/assets/ed9ca45f-7346-463f-b8a4-205bf2c4588f
 
### Step 2: Build the agent in Python code or via UI

### Step 3: Iterate obsessively

### Step 4: Deploy

# ⚡ Quick start

This is the quickest way to get started. Python 3.11 or higher is required.

1. **Install PySpur:**
    ```sh
    pip install pyspur
    ```

2. **Initialize a new project:**
    ```sh
    pyspur init my-project
    cd my-project
    ```
    This will create a new directory with a `.env` file.

3. **Start the server:**
    ```sh
    pyspur serve --sqlite
    ```
    By default, this will start PySpur app at `http://localhost:6080` using a sqlite database.
    We recommend you configure a postgres instance URL in the `.env` file to get a more stable experience.

4. **[Optional] Configure Your Environment and Add API Keys:**
    - **App UI**: Navigate to API Keys tab to add provider keys (OpenAI, Anthropic, etc.)
    - **Manual**: Edit `.env` file (recommended: configure postgres) and restart with `pyspur serve`

# 😎 Feature Reel

## Human-in-the-loop breakpoints:

These breakpoints pause the workflow when reached and resume whenever a human approves it.
They enable human oversight for workflows that require quality assurance: verify critical outputs before the workflow proceeds.

# 🛠️ PySpur Development Setup
#### [ Instructions for development on Unix-like systems. Development on Windows/PC not supported ]

We recommend using Cursor/VS Code with our dev container (`.devcontainer/devcontainer.json`) for:
- Consistent development environment with pre-configured tools and extensions
- Optimized settings for Python and TypeScript development
- Automatic hot-reloading and port forwarding

**Option 1: Cursor/VS Code Dev Container (Recommended)**
1. Install [Cursor](https://www.cursor.com/)/[VS Code](https://code.visualstudio.com/) and the [Dev Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers)
2. Clone and open the repository
3. Click "Reopen in Container" when prompted

**Option 2: Manual Setup**
1. **Clone the repository:**
    ```sh
    git clone https://github.com/PySpur-com/pyspur.git
    cd pyspur
    ```

2. **Launch using docker-compose.dev.yml:**
    ```sh
    docker compose -f docker-compose.dev.yml up --build -d
    ```

3. **Customize your setup:**
    Edit `.env` to configure your environment (e.g., PostgreSQL settings).

Note: Manual setup requires additional configuration and may not include all dev container features.
