What are the server requirements?
A writable PHP hosting directory and a modern browser are enough for the core.
Modern line
The maintained line targets PHP 8. The downloaded lil.php must be executable by the web server, and its directory must be writable during first-run extraction.
Optional capabilities
Individual modules may use ZipArchive, OpenSSL, cURL, IMAP, EXIF, mysqli or other PHP extensions. Missing optional extensions do not invalidate the whole terminal; only the related feature is unavailable.
Legacy line
A frozen PHP 7.4 build remains available for older hosting. It receives compatibility and critical security work, not the full stream of new features.
