This comprehensive guide aims to elucidate the process of installing Devika AI on your system, ensuring you can seamlessly leverage its capabilities for your software development needs.

Prerequisites for Installing Devika AI

Before diving into the installation process, ensure your system meets the following prerequisites:

1. Git Installation: Devika's code is hosted on GitHub, necessitating Git for cloning the repository. Installation instructions for Git are available on its official website.
2. Python Installation: As Devika is built on Python, your system requires Python version 3.6 or later. The Python official website offers the necessary download options.

Step-by-Step Installation Guide

Follow these detailed steps to install Devika AI:

Step 1: Clone the Repository

Open a terminal window and navigate to the directory where you wish to install Devika. Clone the Devika repository from GitHub using the command:

git clone https://github.com/stitionai/devika.git        

Step 2: Navigate to the Cloned Directory

Change to the cloned Devika directory with:

cd devika        

Step 3: Install Dependencies

Inside the Devika directory, install the required dependencies by executing:

pip install -r requirements.txt
playwright install --with-deps # Installs browsers in Playwright (and their dependencies) if required        

Step 4: Set up API Keys (Optional)

Devika can enhance its functionality using various APIs. If you plan to use such features, you must obtain the necessary API keys and configure them in the 'config.toml' file. Refer to the Devika documentation for detailed instructions on API key setup.

Step 5: Start the Devika Server

Launch the Devika server with the following command:

python devika.py        

This command initiates the backend server responsible for processing tasks.

Step 6: Run the UI

Devika features a user interface (UI) as a separate application. Navigate to the 'ui' folder within the Devika directory:

cd ui        

Start the UI server using the command:

bun run dev        

This will launch the UI in your web browser, typically accessible at https://localhost:3000/. You are now ready to interact with Devika through its chat interface.
