Released themes

Compare real page previews, intended use, compatibility, setup, and what editors can change.

Beta

Almanac Theme

The calendar is the site: a living month grid where every day is a page, the past weathers like paper, and the future takes bookings.

Beta

Bistro Theme

A cinematic restaurant theme with a scroll-driven 2.5D story stage, editorial menus, dish rails, chef storytelling, and a resilient reservation path.

Beta

Broadsheet Theme

A premium, layout-native theme for dense data boards, sortable standings, price reports, sparklines, and numbers-first publishing.

Released

Business Theme

Business is a conversion-led theme for quote-driven trades and local-service businesses: state-driven emergency-availability urgency, before/after proof, and a clear path to a quote.

Beta

Concierge Theme

A guided-intake theme that asks one useful question at a time, branches by answer, and hands structured context to the right service path.

Released

Events Theme

Poster-bold surfaces for conferences and live events: agenda grids, speaker walls, ticket tiers, countdown FOMO, sponsor walls, and past-editions archives. Renders through the shared layout-builder container pipeline.

Beta

Folio: Bound Editions Theme

A premium, layout-native theme that turns finite publications into server-numbered, progressively enhanced bound editions.

Released

Foundation Theme

The base theme every Capell site and child theme builds on: shared Blade layouts, a runtime design-token system (colours, spacing, radius), the Tailwind asset pipeline, an SVG sanitiser, and the section/area contracts that vertical themes override.

Beta

Grounds Theme

An illustrated spatial-map theme for organisations with a real place and six to ten nameable landmarks. Desktop visitors can pan and zoom into ordinary page sections; mobile and no-JavaScript visitors receive a district-by-district guide.

Released

Knowledge Base Theme

A search-first documentation theme with structured navigation, API references, changelogs, and reader feedback paths.

Released

Liquid Glass Theme

Theme Liquid Glass gives Capell sites a free modern glass interface with translucent panels, crisp typography, and warm accent actions. Three presets cover bright product launches, editorial glass pages, and darker graphite surfaces while staying fully driven by Theme Studio tokens. It renders through the shared layout-builder container pipeline, keeps public output cache-safe and editor-free, and adds a polished alternative to the Foundation and Corporate free lanes.

Beta

Paperdesk Theme

A tactile premium theme for craft studios, with a deterministic object desk, accessible flip controls, stationery-led sections, and direct enquiry paths.

Beta

Switchboard Theme

A keyboard-first developer-tools theme with a permanent command-bar header, man-page heroes, ruled reference surfaces, and a complete link fallback.

Beta extensions

Beta

Optional Capell Membership extensions that may change or require upgrade work before their Released milestone. Check the risk before enabling one.

Beta

Address

Share one site-scoped address book across Capell packages — countries, structured postal addresses, and admin-managed fields so location data is not remodelled per feature.

A unified, logged-in customer hub for Capell sites — payments, documents, event registrations, gated content and support requests in one secure dashboard.

Included with Capell Membership View Capell Membership access

Demo Kit

The demo engine for Capell: deterministic, multi-site, multi-language sample content and media. Generates a curated showcase site, fans out to each installed package's own demo command, and ships a health doctor so every demo, screenshot, and QA run starts from known data.

Beta

Email Studio

Email Studio is Capell's transactional-email engine and template authoring surface: package-registered static defaults, safe {{ variable }} rendering, editable site and locale overrides, auth email replacements, branded themes, preview/test-send, delivery profiles, suppressions, and a queued audit trail.
