# Why Athina Evals

***Why should I use Athina's Eval framework instead of writing my own evals?[](#why-should-i-use-athinas-eval-framework-instead-of-writing-my-own-evals)***

You could build your own eval system from scratch, but here's why [Athina ](https://github.com/athina-ai/athina-evals) might be better for you.

* Athina provides you with 40+ plug-and-play [preset evals](/evals/preset-evals) that have been well-tested
* Athina allows you to write [custom evals](/evals/custom-evals) that have been well-tested
* Athina evals can run in development, CI / CD, and production, giving you consistent metrics for evaluating model accuracy and safety.
* Athina removes the need for your team to write boilerplate loaders, implement LLMs, normalize data formats, etc
* Athina offers a modular, extensible framework for writing and running evals
* Athina gives you a UI to compare datasets, run evaluations, and keep track of every run.
* Athina calculate analytics like pass rate and flakiness, and segments them so you can compare across different prompts, models, topics, environments and customers.
