This module implement forms using entities. For some inexplicable reason its developer seemed to think its Drupal 8 version needed different name (eform) from its Drupal 7 version (it didn't). Having two different names for D7 and D8 is only a source of confusion that requires a notice on the project page. The Drupal 7 version of Entity Form has a significant number of deployments.
There are multiple competing forms solutions for Drupal 8. The most well developed Drupal 8 forms module is the webform module, which has nearly 500,000 deployments, supports a massive number of features, and is supported by a youtube channel of many detailed tutorial videos by its developer about how to use it.
The Drupal 8 implementation of entity forms has the appearance of an abandoned project, given that its developer has published even a development version of the module since 2016.
