Overview

Verba is a community-driven, open-source Retrieval-Augmented Generation (RAG) application. It offers an end-to-end, user-friendly interface for building RAG workflows on top of a vector database, demonstrating practical semantic search and retrieval patterns using Weaviate.

Features

• End-to-end RAG application: Provides a complete setup for Retrieval-Augmented Generation workflows.
• Weaviate integration: Built to work on top of a Weaviate vector database, using it for storage, semantic search, and retrieval.
• Semantic search: Implements semantic search capabilities as part of the RAG pipeline.
• Retrieval patterns: Showcases practical retrieval patterns and best practices for building RAG systems.
• User-friendly interface: Frontend included (in the frontend directory) for interacting with the RAG chatbot and workflows.
• Python package: Packaged with setup.py and related packaging files (MANIFEST.in, pypi_commands.sh) to allow installation and use as a Python library or service.
• Docker support: Includes a Dockerfile and docker-compose.yml for containerized deployment and easy local setup.
• Technical documentation: Additional docs such as TECHNICAL.md, FRONTEND.md, and PYTHON_TUTORIAL.md for implementation, extension, and usage guidance.
• Community-focused: Structured as a community edition project with contribution guidelines (CONTRIBUTING.md) and changelog (CHANGELOG.md).
• Open source license: Distributed under an open-source license (see LICENSE file in the repository).

Typical Use Cases

• Building and experimenting with RAG chatbots backed by Weaviate.
• Prototyping semantic search applications using vector databases.
• Learning and demonstrating RAG and retrieval patterns in practical setups.

Pricing

• Open Source / Free: Verba is an open-source project available at no cost under its repository license.
