This is a tool to understand your rewrite rules (“Pretty Permalinks”). It is indispensable if you are adding or modifying rules and want to understand how they work (or why they don’t work).
It is only an analyzer, it does not change any rules for you. It parses the rules down to their components and shows the connection with the resulting query variables. It allows you to try out different URLs to see which rules will match and what the value of the different query variables will be (see screenshots).
This plugin was written as a tool to help answering questions about rewrite rules on <a href="http://wordpress.stackexchange.com/" rel="nofollow ugc">the WordPress Stack Exchange</a>.

Throws a warning if WP_DEBUG is on, other than that still a very handy tool to check your rewrite rules.

Very useful

Helped me sort some issues with the rewrite rules when developing a plugin. Works fine with WordPress 5.2 and does what you need it too.

Custom Post Archives bridges the gap between creating Custom Post Types in WordPress 3, and actually displaying those posts. With this plugin, you have 
the option of displaying a completely seperate blog-like section for each post type, complete with all the features you expect to see with WordPress.
For each custom post type, if you click “active” and enter a slug-name, this plugin will let you display post-type specific:
<ul>
<li>Archives</li>
<li>Date archives</li>
<li>Author archives</li>
<li>Category archives</li>
<li>RSS Feeds</li>
</ul>
This plug-in also provides many additional features to fully integrate your custom post types, including:
<ul>
<li>Adds a menu option to the new menu section created in WordPress 3 (for themes that support it)</li>
<li>Combined archives (http://www.mysite.com/type1+type2/)</li>
<li>Option to add post types to default blog</li>
<li>Option to add post types to default RSS feed</li>
<li>Adds post type support to wp_get_archives function</li>
<li>Adds multiple global functions and filters for working with custom post types (see Functions and Filters or Plugin Help for details)</li>
<li>Automatically displays the associated post type on custom taxonomy archives</li>
<li>Extends upon the WordPress templating, allowing for flexibility by theme authors (see FAQ or Plugin Help for details)</li>
<li>Automatically flushes the rewrite cache after modifications are detected</li>
<li>Automatically adds a “blog-{post_type}” type class to the body of the created archives (for themes that implement body_class())</li>
</ul>
