"Multi-site" means two different things

Be aware of the ambiguity. "WordPress Multisite" is a specific feature in WordPress core that lets one install host many sites under sub-domains or sub-paths. "Multiple WordPress installs" is just running, say, five separate WordPress sites on one hosting plan. Hosts treat these differently — some support both, some only one. Our shortlist covers both cases.

Three hosts that genuinely handle multi-site

20i — unlimited WordPress installs on one plan

20i is the obvious value pick. The Managed Hosting plan supports unlimited WordPress installs on a single plan — not "unlimited" with hidden caps, but practically unlimited up to the resource ceiling of the underlying StackCP container. We've personally run 10+ comparison sites on a single 20i plan without trouble.

Cloudways — server-based, scales vertically

Cloudways isn't unlimited but the economics work the same way: you pay for a server, you put as many WordPress installs on it as the box can handle. Vertical scaling lets you bump the server when one site gets busy without affecting the others. Strong fit for the "I have one busy site and several quiet ones" pattern.

HostPresto — multi-site plans with real management

HostPresto's plans scale from 1 to 10 sites with the same fully-managed engineering support across all of them. The economics are less favourable than 20i on pure per-site cost, but you get hands-on plugin help included — which matters when the support call is about one specific site of 10.

Common multi-site gotchas

WordPress Multisite plugin compatibility: A meaningful subset of plugins don't work properly on Multisite. Check before committing — particularly e-commerce, membership and translation plugins.
Database bloat: Multisite installs share one database with prefixed tables. With 50+ sub-sites the database can grow large enough to need its own server.
Update timing: Multisite updates apply network-wide. Test on staging — a buggy plugin update affects every sub-site simultaneously.
Backup granularity: Not every host can restore a single sub-site from a Multisite backup. Confirm before disaster.

Questions

Common questions

Yes, on the Managed Hosting plan. The cap is practical resource limits on the underlying StackCP container, not a hard install count.

No. WordPress Multisite is a single install hosting many sites under sub-domains or sub-paths. Multiple WordPress installs means separate installations sharing one hosting plan. Different trade-offs.

20i is the obvious value pick. Cloudways works well if you need server-level isolation. HostPresto for management quality across all 10.

No — there's a meaningful subset that doesn't test against Multisite. Check the WordPress.org plugin page for Multisite compatibility before installing.
