SiteICO vs A2 Hosting (2026): Speed vs Modern Managed WP

SiteICO vs A2 Hosting: Marketing Speed vs Actual Performance

A2 Hosting markets itself on speed — their "Turbo" plans promise up to 20x faster performance through LiteSpeed web server and server-side caching. SiteICO uses FrankenPHP (a modern PHP runtime built on Caddy) for genuinely fast WordPress execution. Both claim speed; the delivery differs significantly.

A2's Turbo Plans

A2's Turbo plans use LiteSpeed instead of Apache/Nginx for improved performance. These plans start at $6.99/mo (intro) and renew significantly higher. The "20x faster" claim is a marketing comparison against A2's own base shared hosting — not against modern managed platforms.

FrankenPHP Advantage

FrankenPHP introduces worker mode PHP execution, where PHP files stay loaded in memory between requests — eliminating cold start overhead on every request. This architecture is fundamentally more efficient than traditional PHP-FPM or LiteSpeed, resulting in measurably lower TTFB on dynamic WordPress pages.

Verdict

A2 Hosting is a solid shared hosting option for developers who want server-level control and multiple datacenter options. SiteICO delivers better WordPress performance through FrankenPHP, plus AI content tools that A2 doesn't offer. For managed WordPress specifically, SiteICO provides superior value.
