Limit Post Revisions
Keeps only the five most recent revisions of each post, which stops the database from growing with old copies.
Snippet Library
Performance snippets for WordPress
Snippets that make WordPress lighter and faster: remove emoji scripts and embeds, control the Heartbeat API, limit revisions and load scripts only where they are needed. For developers and site owners chasing better Core Web Vitals.
Old Revisions Cleanup Tool
Adds Tools > Clean Up Revisions, which shows how many post revisions your database holds and deletes revisions older than a chosen number of days after you confirm, always keeping the newest few per post.
Revision Limits per Post Type
Keeps a different number of revisions for each content type, for example many for posts and none for products.
Turn Off Autosave for Chosen Post Types
Stops the editor from autosaving the post types you list (for example products or custom data types edited by many people), which removes frequent background requests and extra autosave revisions.
