Plugin Review
AI-ResearchedWhat is Prevent Browser Caching?
Prevent Browser Caching is a focused utility plugin that gives frontend developers direct control over how WordPress serves CSS and JavaScript files. Created by developer kostyatereshchuk, this tool has been actively maintained for 9 years. It currently holds 10K+ active installs and a 4.9/5 rating from 29 reviews. An impressive 97% of those ratings are five-star, with 0% one-star reviews. The plugin solves a common pain point: you want to clear browser cache WordPress users have stored, so they see your latest frontend changes immediately. Instead of asking clients to manually refresh or clear their cache, this plugin handles it automatically.
Version 3.2.1 was last updated on May 2, 2026. The plugin works by appending a unique timestamp number to the ver query parameter in asset URLs. For example, style.css?ver=4.9.6 becomes style.css?ver=4.9.6.1526905286. This forces browsers to treat the file as new and download the updated version. The approach uses standard WordPress functions like wp_enqueue_style and wp_enqueue_script, so it integrates cleanly with any theme or plugin.

- For advanced users, the plugin provides a programmatic API via the `prevent_browser_caching()` function, allowing custom version strings to be set in `functions.php`.
