# athina-evals vs langkit

*GraphCanon updated Sep 20, 2026*

## Verdict

Pick athina-evals if athina-evals is a Python SDK developed for facilitating the evaluation of outputs from large language models through predefined metrics and frameworks; pick langkit if langKit is an open-source toolkit for monitoring Large Language Models (LLMs), offering features such as text quality, relevance metrics, and sentiment analysis to ensure safety and security.

[athina-evals](https://docs.athina.ai) reports 301 GitHub stars, 22 forks, and 4 open issues, last pushed Jun 6, 2025. [langkit](https://whylabs.ai) has 997 stars, 74 forks, and 37 open issues, last pushed Nov 22, 2024. Figures are from public GitHub metadata via [athina-evals's repository](https://github.com/athina-ai/athina-evals) and [langkit's repository](https://github.com/whylabs/langkit).

## Decision facts: athina-evals

- **Adopt for:** athina-evals is a Python SDK developed for facilitating the evaluation of outputs from large language models through predefined metrics and frameworks.

## Decision facts: langkit

- **Adopt for:** LangKit is an open-source toolkit for monitoring Large Language Models (LLMs), offering features such as text quality, relevance metrics, and sentiment analysis to ensure safety and security.

## Choose when

### Choose athina-evals if…

- athina-evals is primarily Python; langkit is Jupyter Notebook.
- Tags unique to athina-evals: evaluation, evaluation-framework, evaluation-metrics, llm-eval.
- When comprehensive evaluation of LLM responses is required, leveraging athina's specific tools and metrics

### Choose langkit if…

- langkit is primarily Jupyter Notebook; athina-evals is Python.
- Tags unique to langkit: large-language-models, machine-learning, nlg, nlp.
- Use LangKit when you need a comprehensive toolkit for monitoring LLMs that includes text quality and relevance metrics, as well as sentiment analysis.

## When NOT to use athina-evals

- If open-source alternatives with transparent customization options are preferred over athina-evals' approach
- In scenarios where API access requirements limit the ability to perform evaluations offline or in private environments

## When NOT to use langkit

- Avoid LangKit if you are looking for a tool that supports languages other than Python, as it is specifically designed for use with Jupyter Notebooks.
- Do not use LangKit if your project requires proprietary licensing, as it is released under the open-source Apache-2.0 license.
