Powerful plugin

Posted on 21 September 2015

Pretty straight forward plugin and I am really thankful for the developer for saving my time.

Ease of use

Its really easy to use but only think I found frustrating is using Firefox for inspect, even though its not a big of a deal.


No need for support, it works out of the box


No need for Documentation, it works out of the box

I used this to: Web development

Great and useful plugin!

There is nothing special to say about the functionality. It just does a great job in compiling LESS on the fly!

Ease of use

The plugin is easy to use.


I found a bug which Andreas fixed over night! Support is top notch!


The plugin is self-explanatory!

I used this to: I use this plugin mostly after deployment and the client wants some changes to be made! It's a lot of hassle to make a backup, restore, fix the issue and then upload to the site again. This plugin makes it easy to make the changes directly online and keep my sources tight!


Works great, minimal control gets the job done with nice extra features for minify and force compiling.

Ease of use

Way easy, turn on, config path, go!

I used this to: Everyday project building and client site maintenance. Because it runs on the site there is no need for me to make sure I am at a computer with my dev tools. Client calls, I can be anywhere, make a change on the go and the plugin takes care of the rest.

This little helper ...

is just another reason to stick with the Joomla CMS. Especially the functionality with "Fire-LESS" Client Side compiling makes working with LESS mcuh more easy, understandable! and just more fun!

Hope you haven't stopped development because the project is still considered as beta?!

Owner's reply: First, thank you (and of course all other reviewers) very much for the positive feedback.

Regarding Beta:
The plugin seems to run very stable - back when I published it I just did not wan't to release a stable version without broader testing. Therefore I will do a stable release with the next maintenance release.

Further Development:
I changed my development workflow a bit and compile all Less/Sass files locally and deploy them afterwards. I still use the plugin for some projects though. Depends on need and contributions to add new functionality.

This is brilliant little plugin and I tested it and it does work - saves me loads of time.

Absolutly essential

While it's not yet in the core, this extension is absolutly essential to work with less files.

While customising your template, you need this. This plugin catch the less file you point in the configuration, from your template less folder, and compile it to a css file in your template css folder.

Thanks to the authors to shared their work !

It works!

Simple to use, and it works.

So, good I forked it! ;)

Wondered about these JavaScript LESS compiler includers forcing guests to activate JS. Started to plan my own plugin based on PHP but foundh this extension for Joomla! 3 early enoug.


Does what it says

This is a necessity when making templates with LESS in 3. Great plugin and easy to use.
