@yougotnet If you are looking for something premium - you might not need any plugins for this because they would provide a bunch of javascript code - at most 10-15 lines that you can add within the head or body tags of your site depending with chat provider - pricing ranges from a low of $9 a month onwards.
If you are looking for something totally open source - a couple of options exists - but are standalone live chat solutions. One such solution you can check out is https://github.com/LiveHelperChat/livehelperchat
The latter would imply separate hosting and installation on your server alongside your laravel app setup or a subfolder within your application.
