カスタムWordPressテーマの再開発

MicrocosmWorks recommends WordPress theme redevelopment when the client has significant existing content, trained staff, and plugin integrations that would be costly to migrate. A custom theme built on modern block editor (Gutenberg) APIs and optimized PHP delivers Core Web Vitals performance comparable to headless setups while preserving the client's existing editorial workflow.

MicrocosmWorks follows a performance-first development approach that includes critical CSS inlining, lazy-loaded images with WebP/AVIF format delivery, minimal JavaScript with deferred loading, and server-side caching through object cache and page cache layers. The result is typically LCP under 1.5 seconds and CLS under 0.05 on mobile devices.

Yes, MicrocosmWorks audits all existing plugins during the discovery phase and designs the theme to maintain compatibility with essential plugins like WooCommerce, Yoast SEO, ACF, and Gravity Forms. The theme uses WordPress hooks and filters correctly so plugin functionality continues working without requiring plugin modifications or replacements.

MicrocosmWorks typically delivers a complete WordPress theme redevelopment in 6-10 weeks depending on the number of unique page templates and custom block types required. The process includes a 1-week discovery phase, 2-3 weeks of design in Figma, 3-5 weeks of development, and 1 week of QA and content migration support.

MicrocosmWorks develops custom WordPress themes at rates of $15-$35/hr, with a full theme redevelopment including custom Gutenberg blocks, WooCommerce integration, and performance optimization typically requiring 200-400 development hours. This is significantly more cost-effective than agencies charging $15,000-$50,000 for comparable scope.
