FAQ
General
Section titled “General”How does LLStack compare to other panels?
Section titled “How does LLStack compare to other panels?”LLStack is purpose-built for performance. It uses LiteHttpd (enhanced OpenLiteSpeed) instead of Apache or Nginx, delivering 2.5x Apache’s static file performance while maintaining full .htaccess compatibility. Unlike BT Panel or CyberPanel, LLStack includes a complete WordPress Toolkit comparable to Plesk’s, with Smart Update, security scanning, and Redis Object Cache integration. See the homepage for a detailed feature comparison.
What operating systems are supported?
Section titled “What operating systems are supported?”LLStack supports EL9 and EL10 distributions:
- Rocky Linux 9.x / 10.x
- AlmaLinux 9.x / 10.x
- CentOS Stream 9 / 10
- Oracle Linux 9 / 10
- RHEL 9 / 10
Ubuntu and Debian are not currently supported.
Is LLStack free?
Section titled “Is LLStack free?”LLStack is open-source software. The core panel is free to use. Some advanced features may be available as optional paid add-ons in the future, but the open-source edition covers all essential server management needs.
LiteHttpd
Section titled “LiteHttpd”What is the difference between LiteHttpd and OpenLiteSpeed?
Section titled “What is the difference between LiteHttpd and OpenLiteSpeed?”LiteHttpd is built on top of OpenLiteSpeed and adds four key enhancements:
- Full .htaccess module — supports 80+ Apache directives (stock OLS has limited .htaccess support)
- Kernel patches — optimized connection handling and I/O for EL9/EL10
- Config converter —
litehttpd-confconvtool for migrating Apache configurations - Performance tuning — pre-configured for optimal performance out of the box
See the LiteHttpd Engine page for benchmarks and details.
Does LiteHttpd support .htaccess?
Section titled “Does LiteHttpd support .htaccess?”Yes. LiteHttpd supports 80+ Apache .htaccess directives, including mod_rewrite, mod_headers, mod_expires, mod_auth_basic, and mod_deflate. WordPress plugins that rely on .htaccess (Yoast SEO, W3 Total Cache, security plugins) work without modifications.
Which PHP versions are supported?
Section titled “Which PHP versions are supported?”LLStack supports PHP 7.4, 8.0, 8.1, 8.2, 8.3, and 8.4 via the REMI repository. Multiple versions can be installed simultaneously, and each site can use a different PHP version.
All PHP versions use the php-litespeed SAPI (LSAPI protocol) for optimal performance with LiteHttpd.
Can I use php-fpm instead of LSAPI?
Section titled “Can I use php-fpm instead of LSAPI?”LLStack uses PHP-LiteSpeed SAPI (LSAPI) exclusively. LSAPI provides 30% fewer context switches than php-fpm and is natively managed by LiteHttpd. There is no need to configure separate php-fpm pools.
Migration
Section titled “Migration”How do I migrate from another panel?
Section titled “How do I migrate from another panel?”LLStack provides migration guides for:
- BT Panel (宝塔) — export/import via tar + mysqldump
- CyberPanel — similar workflow, with OLS rewrite rule migration
- cPanel/WHM — use cPanel’s built-in backup, then import
- Apache — use
litehttpd-confconvfor automatic config conversion
See the Migration Guide for step-by-step instructions.
Will my WordPress .htaccess rules work?
Section titled “Will my WordPress .htaccess rules work?”Yes. LiteHttpd’s .htaccess support covers all standard WordPress rewrite rules, permalink structures, and plugin-generated rules. No modifications are needed.
Data & Storage

Section titled “Does LLStack support Docker?”LLStack is designed to run directly on the host OS, not inside Docker. The panel manages system-level services (LiteHttpd, PHP, MariaDB, Redis) that require direct access to the host. Running inside a container is not officially supported.

| CPU | 1 core | 2+ cores |
| RAM | 1 GB | 2+ GB |
| Disk | 5 GB | 20+ GB |
| OS | EL9 | EL9 or EL10 |
| Network | Public IP | Public IP + domain |
WordPress
Section titled “WordPress”Is LLStack compatible with all WordPress plugins?
Section titled “Is LLStack compatible with all WordPress plugins?”LLStack is fully compatible with WordPress.
