LiteSpeed vs OpenLiteSpeed — same engine, different ceilings

OpenLiteSpeed is not a crippled demo — it is the same event-driven engine, open-sourced, with HTTP/3 support and LSCache included. Plenty of quick sites run on it, and for a developer with root access and a stable configuration it costs nothing and gives away little.

But 'same engine' is not 'same product', and the differences are exactly the kind that never appear in a benchmark: how configuration reloads, what control panels can manage it, which security stacks it slots into. This page lays out the real differences so you can tell which build a platform runs — and whether it matters for your site.

Enterprise parses .htaccess on every request, exactly as Apache does. Change a rule, and the next request obeys it. OpenLiteSpeed reads rewrite rules once, at start-up, and holds them in memory: edits sit inert until the server is restarted.

On a hand-managed VPS that is a tolerable discipline. On a real WordPress site it is a trap, because plugins write rules without telling you — security plugins tightening access, cache plugins adding directives, redirect managers doing their job. Under OpenLiteSpeed each of those silent writes needs a restart nobody knows to perform, and the symptom is rules that mysteriously do not apply.

Both builds can present themselves as LiteSpeed in headers, so marketing that says 'LiteSpeed servers' has not yet told you which product is underneath. The honest test is to ask directly — a platform running Enterprise under cPanel will say so without hesitation, because the licence is a cost they chose for a reason.

There is also a behavioural test: change a rewrite rule and see whether it applies without a restart. Our shared platform runs the Enterprise build under cPanel; the per-request .htaccess behaviour and the CloudLinux integration are not optional extras for multi-tenant hosting done properly.
