FAQ
WordPress is the right choice when content editors need a familiar, powerful interface; you need a wide plugin ecosystem; or you are building a content-heavy site like a blog, news site, or marketing site with frequent page creation. For complex web apps, a custom CMS or headless approach is usually better.
Yes. We build custom block themes from scratch using the Full Site Editor - not pre-built themes with excessive CSS overrides. Our themes are lean, accessible, and aligned with your design system from day one.
Headless WordPress uses WordPress purely as a content management backend while serving the frontend through a separate framework like Next.js. Editors enjoy the familiar WordPress UI, but visitors get a blazing-fast, fully custom frontend with complete design freedom.
Yes. Advanced Custom Fields Pro is our tool of choice for structured content - field groups, repeaters, flexible content layouts, and relationship fields. We combine ACF with custom post types to model content accurately for your site architecture.
We implement Redis object caching, full-page caching (WP Rocket or custom Nginx rules), serve images through Cloudinary or a CDN, defer non-critical scripts, and eliminate render-blocking CSS. Properly optimized WordPress sites regularly score 90+ on PageSpeed.
We harden wp-config.php, move wp-login.php, disable XML-RPC, enforce strong passwords with 2FA, audit plugin permissions, apply least-privilege user roles, keep core and plugins updated, and run a web application firewall (Cloudflare or Wordfence).
Yes. Kultrix migrates sites from Wix, Squarespace, Webflow, Drupal, and custom platforms to WordPress. We migrate content, redirect old URLs to preserve SEO, and validate the migration before cutting over DNS.
Yes. We build WooCommerce stores with custom product types, checkout customizations, payment gateway integrations, and performance optimization. For high-volume stores, we often recommend a headless WooCommerce setup with a Next.js storefront.
WordPress Multisite is ideal for managing multiple sites from a single WordPress installation - franchise networks, multi-brand publishers, or agency white-label setups. Kultrix configures Multisite with shared plugins, per-site themes, and proper subdomain or subdirectory routing.
Yes. We build custom Gutenberg blocks using React - fully aligned with your design system, with intuitive inspector controls for editors and clean HTML output for SEO. Custom blocks replace the plugin-soup approach most WordPress sites accumulate.
Yes. Kultrix offers monthly maintenance plans covering core and plugin updates, uptime monitoring, daily backups, security scanning, and a bank of development hours for content updates or small feature requests.
A custom WordPress site takes 4-8 weeks. A headless WordPress + Next.js project takes 8-14 weeks. Plugin development timelines vary by complexity. Kultrix provides a detailed timeline with clear milestones after scoping.
