PromptTools is an open-source Python library for testing, experimenting with, and evaluating prompts, LLMs (OpenAI, Anthropic, LLaMA, etc.), and vector databases (Chroma, Weaviate, LanceDB). It supports evaluation via code, Jupyter notebooks, and a local Streamlit playground.

Use cases

• compare prompt outputs across multiple LLM models
• evaluate retrieval accuracy of a vector database
• A/B test prompt templates and model parameters like temperature
• run LLM experiments in a Jupyter notebook
• self-host a playground for prompt experimentation
• evaluate responses from OpenAI, Anthropic, or LLaMA models

When to choose

• you need to systematically test and compare prompts or LLM parameters
• you want to benchmark vector database retrieval quality
• you prefer notebook-based or self-hosted evaluation workflows
• you want a free, open-source alternative to hosted prompt evaluation tools

When to avoid

• you need production LLM observability and tracing in live applications
• you want a fully managed cloud evaluation service
• you need CI-integrated LLM testing pipelines with team dashboards
