PrestaShop support is a useful compatibility signal, not a capacity plan. A production store needs current PHP, a suitable database, HTTPS, recoverable backups and enough memory for modules, images, index work and administration. Review those operational limits before selecting a plan based on a low introductory price.
A small shop can start on shared hosting. Stores with large catalogues, active integrations or busy checkout flows need predictable process and cache capacity; a Linux VPS is often the clearer next step. Keep the hosting choice tied to measured workload, not to the number of products advertised by a generic plan.
Straight answers about ranking methodology, pricing and choosing the right plan.
Not for every store. A small, well-cached shop can use shared hosting. A large catalogue, many modules or heavy integrations can outgrow shared process and memory limits quickly.
Check current PHP, database support, memory limits, image and file policies, SSL, backups and cron. These features affect updates and checkout reliability more than a generic CMS label.
