Curated themes

Active Admin Claude Theme

A warm, editorial theme inspired by Claude and Anthropic aesthetics. It recolors ActiveAdmin 4 through Tailwind v4 theme tokens and CSS variables, while preserving the built-in dark-mode toggle, mobile drawer, and Flowbite hooks.

Field	Details
Project	paladini/activeadmin-claude-theme
License	MIT
ActiveAdmin	4.0.0.beta22+
Styling	Tailwind CSS v4
Rails integration	Rails Engine gem with an install generator
Status	AA4 verified

Install

Add the gem to your Rails application's Gemfile:

gem "activeadmin-claude-theme"

Then install the gem and run its generator:

bundle install
rails generate activeadmin_claude_theme:install
npm run build:css

Your application must already use ActiveAdmin 4 with Tailwind v4 assets. See the theme installation guide for the required ActiveAdmin, cssbundling-rails, and importmap-rails setup.

Known limitations

• The theme requires ActiveAdmin 4.0.0.beta22 or newer.
• It is not a drop-in replacement for legacy Sprockets or SCSS themes.
• Anthropic and Claude are referenced for design inspiration only; the project is not affiliated with or endorsed by Anthropic.

What counts as ActiveAdmin 4 support?

A project qualifies for the curated list when its documentation or tests provide enough evidence that it works with the ActiveAdmin 4 architecture:

• It names an ActiveAdmin 4 version or range, ideally including the latest beta.
• Its installation instructions use the ActiveAdmin 4 asset pipeline and styling model, rather than only active_admin/base SCSS imports.
• Its screenshots or demo show the theme running in an ActiveAdmin 4 app.
• Its license and source repository are publicly available.

ActiveAdmin 4 is still released as a beta series. The latest version checked for this list is 4.0.0.beta22. Confirm the upstream compatibility range before installing a theme in production.

Excluded and pending projects

The following projects were found during the initial survey but are not listed as ActiveAdmin 4 themes because their current documentation does not verify compatibility with the AA4 Tailwind architecture:

• Arctic Admin — SCSS-based integration documented for the classic asset pipeline.
• ActiveAdminTheme — legacy SCSS theme with ActiveAdmin 3-era installation instructions.
• Light Admin — classic SCSS theme; AA4 compatibility is not documented.
• ActiveAdmin Blaze Theme — Blaze CSS and legacy ActiveAdmin asset integration.
• ActiveAdmin AAA Theme — modern visual design, but its current documentation targets ActiveAdmin 3+ and SCSS rather than verified AA4 support.
• ActiveAdmin Prism — promising candidate that declares ActiveAdmin >= 3.0, but still needs an AA4/Tailwind compatibility demonstration.

These projects may become eligible when their maintainers document and verify ActiveAdmin 4 support. They are not quality judgments.
