Slug-Free Permalinks lets you switch selected post types and taxonomies to simple ID based permalink formats.
You can choose between:
<ul>
<li><code>/post/123/</code></li>
<li><code>/post-123/</code></li>
</ul>
The plugin only affects the post types and taxonomies you enable in the settings screen.
Features:
<ul>
<li>Select individual public post types</li>
<li>Select individual public taxonomies</li>
<li>Choose slash or hyphen based ID permalink format</li>
<li>Optionally redirect legacy slug URLs to the current ID based permalink when WordPress can resolve the request</li>
<li>Preserve prefixed permalink bases such as <code>/en/</code> when another plugin adds them</li>
<li>Flush rewrite rules automatically when settings change</li>
</ul>
This plugin is focused on permalink structure only. It does not add content features or front-end UI.

Development repository: https://github.com/1008k/slug-free-permalinks
This plugin is best suited to new sites, sites still defining their permalink policy, or structured-content use cases where slug management is unnecessary.
If your site already has a large number of published posts and established slug based URLs, review the impact carefully before enabling it. Check existing inbound links, search traffic, social shares, and editorial workflow assumptions.
Known limitations:
<ul>
<li>If a post type slug and taxonomy slug are identical, their ID based rewrite patterns can conflict.</li>
</ul>

Slug-Free Permalinks – Simple ID-Based URLs

Why Use This Plugin?
When sharing links with titles in non-English languages (e.g. Hebrew, Korean, Japanese, Hindi, Arabic, Chinese, or Russian) on platforms like Facebook or WhatsApp, the URLs often turn into a confusing string of codes. This makes your links look unprofessional, reduces click-through rates, and can harm your SEO.
The Automatic Slug Translator fixes this issue by seamlessly translating slugs into concise English. Not only does this make your links visually appealing and user-friendly, but it also enhances your website’s search engine performance with clear, descriptive URLs.
Key Benefits: 
– Improves Sharing: Makes links cleaner and more attractive on social platforms. 
– Boosts SEO: Search engines favor clear, readable URLs. 
– Simplifies Titles: Long, complex titles are automatically shortened into elegant slugs.
Example: 
– Original Title (Hebrew): איך להשתמש בממיר אוטומטי לסלאג באנגלית 
– Default Slug: /איך-להשתמש-בממיר-אוטומטי-לסלאג-באנגלית 
– Broken URL: /%D7%90%D7%99%D7%9A-%D7%9C%D7%94%D7%A9%D7%AA%D7%9E%D7%A9…

This small adjustment can have a big impact on how your content is shared and discovered.
