On-the-fly replacement of any text or HTML in Joomla page output, with regular expression support; the database and site files stay untouched.
ReReplacer by Regular Labs is a component and system plugin that searches the HTML of a page just before it is sent to the visitor and swaps the matching fragment for something else. Rules run on every request, so they are easy to switch off or change. It helps administrators and developers adjust the output of a third-party extension or template without editing its source.
Features
- Search and replace in the final page HTML using plain text or regular expressions.
- Custom shortcode tags, for example
[mytag]text[/mytag], turned into the desired markup. - Changes to core and extension output without modifying their files.
- A bad word filter.
- Temporarily hiding text without deleting it from articles.
- Stripping redundant whitespace from the page code.
- Abbreviations and reusable blocks: a single word such as
[footer]or[stats]expands into text or code maintained in one place for the whole site.
Limitations
Replacements are not permanent: ReReplacer does not change the database or PHP files. For database edits the same developer offers DB Replacer.
Compatibility
- Joomla 4, 5 and 6.
- Current version 16.2.0, last updated in JED on 13 September 2026.
