## Choose when

### Choose promptfoo if…

- promptfoo is primarily TypeScript; Promptify is Python.
- License: promptfoo is MIT, Promptify is Apache-2.0.
- Both Promptify and promptfoo deal with evaluating prompts in the context of LLM applications, but they approach it differently. While Promptify emphasizes structured outputs and task-based NLP, promptfoo focuses on CLI evaluation and red-teaming.
- Tags unique to promptfoo: ci-cd, evaluation, prompt-testing, ci.
- promptfoo ships Docker support for self-hosted deployment.
- When you need to evaluate the performance of different LLMs such as OpenAI, Anthropic, Azure, Bedrock, Ollama, etc., within a single interface.

### Choose Promptify if…

- Promptify is primarily Python; promptfoo is TypeScript.
- License: Promptify is Apache-2.0, promptfoo is MIT.
- Requirements: Requires Python 3.9 or higher; Can be installed via pip or directly from GitHub.
- Both Promptify and promptfoo deal with evaluating prompts in the context of LLM applications, but they approach it differently. While Promptify emphasizes structured outputs and task-based NLP, promptfoo focuses on CLI evaluation and red-teaming.
- Tags unique to Promptify: gpt-3, nlp, machine-learning, gpt-4.
- Also covers LLM Frameworks.
- When your application requires structured NLP outputs with clear schemas defined using Pydantic

## When NOT to use promptfoo

- When your environment does not support Node.js, as this is a requirement for Promptfoo's functionalities.
- If you are looking for a tool that only focuses on model training or fine-tuning without the emphasis on evaluation and red-teaming aspects of language models.

## When NOT to use Promptify

- When your project does not require structured outputs or if Pydantic schemas are not suitable for your use case
- If you do not need built-in evaluation metrics for prompt performance and prefer more customization in the evaluation process
- In situations where integration with only a few specific LLMs is required, as Promptify's advantage lies in its flexibility across various providers
