You have three deployment options for Verba:
- Install via pip
pip install goldenverba
- Build from Source
git clone https://github.com/weaviate/Verba
pip install -e .
- Use Docker for Deployment
Prerequisites: If you're not using Docker, ensure that you have Python >=3.10.0 installed on your system.
git clone https://github.com/weaviate/Verba
docker compose --env-file <your-env-file> up -d --build
If you're unfamiliar with Python and Virtual Environments, please read the python tutorial guidelines.
You can set all API keys in the Verba frontend, but to make your life easier, we can also prepare a .env file in which Verba will automatically look for the keys. Create a .env in the same directory you want to start Verba in. You can find an .env.example file in the goldenverba directory.
Make sure to only set environment variables you intend to use, environment variables with missing or incorrect values may lead to errors.
Below is a comprehensive list of the API keys and variables you may require:
| Environment Variable | Value | Description |

Verba provides flexibility in connecting to Weaviate instances based on your needs. You have three options:
- Local Deployment: Use Weaviate Embedded which runs locally on your device (except Windows, choose the Docker/Cloud Deployment)
- Docker Deployment: Choose this option when you're running Verba's Dockerfile.
- Cloud Deployment: Use an existing Weaviate instance hosted on WCD to run Verba
🌩️ Weaviate Cloud Deployment (WCD)
If you prefer a cloud-based solution, Weaviate Cloud (WCD) offers a scalable, managed environment. Learn how to set up a cloud cluster and get the API keys by following the Weaviate Cluster Setup Guide.
🐳 Docker Deployment Another local alternative is deploying Weaviate using Docker. For more details, follow the How to install Verba with Docker section.
Verba supports Ollama models. Download and Install Ollama on your device (https://ollama.com/download). Make sure to install your preferred LLM using ollama run <model>.
Tested with llama3, llama3:70b and mistral. The bigger models generally perform better, but need more computational power.
Make sure Ollama Server runs in the background and that you don't ingest documents with different ollama models since their vector dimension can vary that will lead to errors
You can verify that by running the following command
ollama run llama3
Verba supports importing documents through Unstructured IO (e.g plain text, .pdf, .csv, and more). To use them you need the UNSTRUCTURED_API_KEY and UNSTRUCTURED_API_URL environment variable. You can get it from Unstructured
UNSTRUCTURED_API_URL is set to
https://api.unstructuredapp.io/general/v0/generalby default
Verba supports importing documents through AssemblyAI (audio files or audio from video files). To use them you need the ASSEMBLYAI_API_KEY environment variable. You can get it from AssemblyAI
Verba supports OpenAI Models such as Ada, GPT3, and GPT4. To use them, you need to specify the OPENAI_API_KEY environment variable. You can get it from OpenAI
You can also add a OPENAI_BASE_URL to use proxies such as LiteLLM (https://github.com/BerriAI/litellm)
OPENAI_BASE_URL=YOUR-OPENAI_BASE_URL
If you want to use the HuggingFace Features, make sure to install the correct Verba package. It will install required packages to use the local embedding models. Please note that on startup, Verba will automatically download and install embedding models when used.
pip install goldenverba[huggingface]
or
pip install `.[huggingface]`If you're using Docker, modify the Dockerfile accordingly
To use Groq LPUs as generation engine, you need to get an API key from Groq.
Although you can provide it in the graphical interface when Verba is up, it is recommended to specify it as
GROQ_API_KEYenvironment variable before you launch the application.
It will allow you to choose the generation model in an up-to-date available models list.
Python >=3.10.0
- (Very Important) Initialize a new Python Environment
python3 -m virtualenv venv
- Install Verba
pip install goldenverba
- Launch Verba
verba start
You can specify the --port and --host via flags
- Access Verba
Visit localhost:8000
- (Optional)Create .env file and add environment variables
- Clone the Verba repos
git clone https://github.com/weaviate/Verba.git
- Initialize a new Python Environment
python3 -m virtualenv venv
- Install Verba
pip install -e .
- Launch Verba
verba start
You can specify the --port and --host via flags
- Access Verba
Visit localhost:8000
- (Optional) Create .env file and add environment variables
Docker is a set of platform-as-a-service products that use OS-level virtualization to deliver software in packages called containers. To get started with deploying Verba using Docker, follow the steps below. If you need more detailed instructions on Docker usage, check out the Docker Curriculum.
- Clone the Verba repos Ensure you have Git installed on your system. Then, open a terminal or command prompt and run the following command to clone the Verba repository:
git clone https://github.com/weaviate/Verba.git
-
Set necessary environment variables Make sure to set your required environment variables in the
.envfile. You can read more about how to set them up in the API Keys Section -
Adjust the docker-compose file You can use the
docker-compose.ymlto add required environment variables under theverbaservice and can also adjust the Weaviate Docker settings to enable Authentification or change other settings of your database instance. You can read more about the Weaviate configuration in our docker-compose documentation
Please make sure to only add environment variables that you really need.
- Deploy using Docker With Docker installed and the Verba repository cloned, navigate to the directory containing the Docker Compose file in your terminal or command prompt. Run the following command to start the Verba application in detached mode, which allows it to run in the background:
docker compose up -d
docker compose --env-file goldenverba/.env up -d --build
This command will download the necessary Docker images, create containers, and start Verba. Remember, Docker must be installed on your system to use this method. For installation instructions and more details about Docker, visit the official Docker documentation.
- Access Verba
-
You can access your local Weaviate instance at
localhost:8080 -
You can access the Verba frontend at
localhost:8000
If you want your Docker Instance to install a specific version of Verba you can edit the Dockerfile and change the installation line.
RUN pip install -e '.'
The first screen you'll see is the deployment screen. Here you can select between Local, Docker, Weaviate Cloud, or Custom deployment. The Local deployment is using Weaviate Embedded under the hood, which initializes a Weaviate instance behind the scenes. The Docker deployment is using a separate Weaviate instance that is running inside the same Docker network. The Weaviate Cloud deployment is using a Weaviate instance that is hosted on Weaviate Cloud Services (WCS). The Custom deployment allows you to specify your own Weaviate instance URL, PORT, and API key.
First thing you need to do is to add your data. You can do this by clicking on Import Data and selecting either Add Files, Add Directory, or Add URL tab. Here you can add all your files that you want to ingest.
You can then configure every file individually by selecting the file and clicking on Overview or Configure tab.
With Data imported, you can use the Chat page to ask any related questions. You will receive relevant chunks that are semantically relevant to your question and an answer generated by your choosen model. You can configure the RAG pipeline under the Config tab.
Your contributions are always welcome! Feel free to contribute ideas, feedback, or create issues and bug reports if you find any! Before contributing, please read the Contribution Guide. Visit our Weaviate Community Forum if you need any help!
You can learn more about Verba's architecture and implementation in its technical documentation and frontend documentation. It's recommended to have a look at them before making any contributions.
- Weaviate Embeeded currently not working on Windows yet
- Will be fixed in future versions, until then please use the Docker or WCS Deployment

Is Verba Multi-Lingual?
- This depends on your choosen Embedding and Generation Model whether they support multi-lingual data.

Can I use my Ollama Server with the Verba Docker?
- Yes, you can! Make sure the URL is set to:
OLLAMA_URL=http://host.docker.internal:11434 - If you're running on Linux, you might need to get the IP Gateway of the Ollama server:
OLLAMA_URL="http://YOUR-IP-OF-OLLAMA:11434"
- Yes, you can! Make sure the URL is set to:
