The most common build question in Pakistan, answered honestly.
WordPress wins when - Non-technical people must edit content (posts, products, pages) - You need plugins: forms, SEO tools, multilingual, bookings - The site is content-heavy: blogs, news, catalogues - Speed of assembly matters: theme + plugins beats weeks of coding
Costs: free software, PKR 5,000–20,000 premium themes (or PKR 0 with a lean free theme), plugin subscriptions occasionally.
Custom PHP wins when - The site is a fixed shape: a 5-page business site, a landing page, a portfolio - Speed and slimness matter most: no plugin weight, pages in milliseconds - Security surface is minimal: no third-party plugin supply chain - It is a learning project or you enjoy the control
Costs: your time (or a developer's), hosting only — no licences.
