Which scales better, Laravel or WordPress?

Both can scale to high traffic with proper architecture, but they scale differently. WordPress scales horizontally through caching (Varnish, full page cache, object cache), CDN offload, and database read replicas, but hits architectural limits when significant custom application logic enters the request path. Laravel scales through the framework itself (Octane plus Horizon plus Redis) with no plugin overhead in the request path, which is why it powers products like 9GAG at hundreds of millions of monthly users. For pure content sites WordPress scales well with caching; for application heavy products Laravel typically scales further per dollar of infrastructure.
