Unapp

Unapp is a lightweight WordPress block theme for app, SaaS and startup landing pages by Colorlib. Version 2.0 is a ground-up rewrite for the Site Editor: no page-builder framework, no jQuery, no icon fonts — just core blocks, theme.json and patterns.

Highlights

• Complete landing page on activation – a real "Home" page (editable page content, Page (No Title) template) and a "Blog" page are created and assigned in Settings → Reading; existing front pages are never overridden (a one-click notice is shown instead). Gradient hero with product screenshot, services grid, image & text, features around a phone, animated stats, screenshot gallery (core lightbox), pricing table, team, latest posts, call to action and contact cards.
• 14 patterns + 3 page starters (Home, About, Pricing) — every section is reusable on any page.
• Section styles for Group blocks: Card, Soft background, Dark, Gradient. Block styles: Checklist (List), Device frame (Image).
• Color variations: default, Emerald, Sunset, Midnight (dark).
• Performance: self-hosted Poppins/Nunito (woff2, latin + latin-ext subsets, ~160 KB total), AVIF images, fluid type, one 2 KB script loaded only where the Stats pattern is used, per-block CSS loaded on demand.
• Security: all pattern output escaped, no direct file access, no external requests.

Requirements

• WordPress 6.6+ (theme.json v3, section styles) — tested up to 7.0
• PHP 7.4+

Customising

• Colors / fonts / spacing – Appearance → Editor → Styles, or edit theme.json. Add a palette variation by dropping a JSON file into styles/.
• Header / footer – Appearance → Editor → Patterns → Template Parts, or edit patterns/header.php / patterns/footer.php (the parts only reference these patterns).
• New section – add patterns/my-section.php with a Slug: unapp/my-section header and the unapp category; escape every string with esc_html_e() / esc_attr() / esc_url().
• Section look – select any Group and pick Card / Soft background / Dark / Gradient under Styles. Add more by creating styles/section-*.json with "blockTypes".

Front page behaviour

There is deliberately no front-page.html. On activation inc/front-page-setup.php creates a Home page whose content is the fully expanded "Home landing page" pattern (template Page (No Title)) plus a Blog page, and sets show_on_front, page_on_front, page_for_posts. It only does this automatically when the site has no static front page; otherwise an admin notice offers a one-click setup. The run is recorded in the unapp_front_page_setup option and never repeated. Disable with add_filter( 'unapp_auto_setup_front_page', '__return_false' ).

Development

There is no build step. Edit files directly; PHP patterns are lint-able with php -l, JSON with any validator.

Regenerate the translation template with WP-CLI:
