Monthly price on annual billing, selected plans (USD)
Source: the two pricing pages, read 2026-11-02. SiteGround intro prices are prepaid for 12 months; Kinsta figures are the annual-billing monthly rates.
Plans and limits
Kinsta's WP 2 to WP 40 plans list 2, 5, 10, 20 and 40 WordPress installs with 20GB to 60GB of storage; extra sites are listed at $30 USD a month each and extra disk at $20 USD per 20GB. SiteGround's StartUp covers one website with 10 GB, while GrowBig (50 GB) and GoGeek (100 GB) list unlimited websites with unlimited traffic. The count is not capacity: storage is the cap on SiteGround, and the install count is the cap on Kinsta.
Performance and architecture
Neither page read gives a measured uptime or speed figure HostingDive can restate. SiteGround markets its own before-and-after speed comparison, and Kinsta lists an up to 99.99% SLA on Enterprise, but both are vendor statements. For measured response data use the Speed Index and the test method.
Managed features
SiteGround lists free SSL, CDN and backups, free site migrations, managed auto-updates, WP-CLI and SSH on every plan, with on-demand backups and staging from GrowBig and staging with Git, private DNS and white-label access on GoGeek. Kinsta lists enterprise DDoS protection, a CDN, advanced caching, automatic daily backups, unlimited migrations with no downtime, uptime monitoring and APM across plans; premium staging environments are a paid add-on.
Support
SiteGround lists real 24/7 human support, with priority support on GoGeek. Kinsta lists 24/7 human support in 8 languages.
