ARCHITECTURE

Go vs PHP: A Fundamental Difference

The choice of backend language affects everything from memory usage to response times

Panelica (Go 1.24)

  • ✓ Compiled binary -- no interpreter overhead
  • ✓ ~50MB base memory footprint
  • ✓ Built-in concurrency with goroutines
  • ✓ Single binary deployment
  • ✓ Type-safe codebase (~215K lines)
  • ✓ Built-in WebSocket support

Plesk (PHP)

  • - Interpreted -- requires PHP runtime
  • - ~300MB+ base memory with extensions
  • - Process-based concurrency (PHP-FPM)
  • - Multi-file deployment with dependencies
  • - Dynamically typed
  • - WebSocket requires additional libraries
KEY DIFFERENCES

Where Panelica Stands Out Against Plesk

Isolation Architecture

Plesk provides basic per-subscription resource limits. Panelica goes further with 5 distinct isolation layers: Cgroups v2 for CPU/RAM/IO limits, kernel namespaces for process and mount isolation, SSH chroot for shell access control, per-user per-version PHP-FPM pools, and strict Unix permission separation. Each layer works independently, providing defense in depth.

Docker Support

Plesk offers a basic Docker extension that allows running containers. Panelica provides a full Docker management interface with 160+ pre-built application templates, RBAC integration (users only see their own containers), Cgroups v2 resource tracking per container, and one-click deployment of complex applications like OpenVPN, development stacks, and monitoring tools.

WordPress Performance

Plesk includes WP Toolkit for WordPress management, which handles staging, cloning, and security scanning. Panelica also provides WordPress management but adds a custom Panelica WP Boost acceleration layer: both Object Cache and Full-Page Cache are built directly into the panel. Cached pages can be served in approximately 2ms with Panelica WP Boost, without requiring any WordPress plugins.

Cost Structure

Plesk starts at $11.95/month for the Web Admin tier (up to 10 domains) and goes up to $58.95/month for the Obsidian tier. Many useful features require paid extensions on top of the base license. Panelica starts at $0/month with a free tier and includes all features in every license -- no paid extensions or add-ons needed.

FAQ

Frequently Asked Questions

Yes. Panelica is a full-featured server management platform that covers the same use cases as Plesk: domain management, email, databases, DNS, SSL, backups, WordPress management, and security. It is built with Go and React, providing a lighter resource footprint and modern architecture compared to Plesk's PHP-based stack.

Yes. Panelica includes a built-in migration engine with a dedicated Plesk adapter. It connects to your Plesk server, discovers all subscriptions, and transfers domains, files, databases, email accounts, and SSL certificates automatically. The migration runs with real-time progress tracking and supports automatic rollback.

Both platforms offer WordPress management capabilities like installation, staging, and security scanning. Panelica adds a custom Panelica WP Boost acceleration layer that provides both Object Cache and Full-Page Cache directly from the panel, without requiring WordPress plugins. This can serve cached pages in approximately 2ms with Panelica WP Boost.

Panelica has its own architecture and does not support Plesk extensions. However, most features that require paid extensions in Plesk -- such as monitoring (Grafana), malware scanning (ClamAV), Docker management, and WAF -- are already built into Panelica at no additional cost.

Yes. Panelica's Go backend compiles to a single binary that uses approximately 50MB of RAM at baseline. Plesk's PHP-based stack, with its various services and extensions, typically uses 300MB or more. This difference matters especially on smaller VPS instances where every megabyte counts.
