Liglis is free open-source PHP solution for hosting Lightpath scripts. It's completely open, has no registration or other cumbersome features.
You can download the sources and extract them into your public directory or a subfolder. After tweaking CSS styles and HTML templates it will just work.
No database or anything else is required except for PHP 5.3 itself. Just make sure to give write permissions for cache/ and data/ directories.
If you want to make it private then use your web server's capabilities to enable HTTP Authentication — for example, via AuthType Basic for Apache or auth_basic for nginx.
If you have questions feel free to drop by our forum.
☼ May you follow the light path ☼
