/ The reality

WordPress can't carry your product anymore. Upgrade.

If your web app is held together with WordPress plugins, jQuery and a freelancer who left the country, every new feature is a risk. Codev Digital builds modern, type-safe Next.js applications engineered for speed, accessibility, SEO and uptime. The stack used by Linear, Notion, Cal.com and Vercel, assembled by senior operators who ship for a living.

Brittle stacks

WordPress + 12 plugins isn't a product, it's a security incident waiting to happen.

Slow loads, lost revenue

Every 100ms of load time costs you 1% in conversion. Your app is bleeding money quietly.

Mobile is broken

Built for desktop in 2019, jammed onto phones in 2023. Users bounce. Google penalises you.

No real engineers in the loop

When something breaks, the only person who understands the codebase is unreachable.

/ Deliverables

What goes into the build
Engineering, not assembly.

Every Codev web app is engineered for performance, SEO, accessibility and long-term maintainability, not stitched together from page builders.

/ Web App Development FAQ

Honest answers to every question we get.

Still unsure? Book a 30-minute strategy call. No pressure, no pitch deck, just a conversation about your idea.

We don't build production web apps on page builders. We use Next.js, React and Node, the same modern stack used by the top product teams in the world. For static marketing sites we can integrate a headless CMS (Sanity, Contentful) so your team can still edit content.
