Modules for Backdrop CMS

Antibot is an extremely lightweight module designed to eliminate robotic form
submissions on your website in an innovative-fashion. The module works
completely behind the scenes and doesn't require any interaction from the
end-users (no annoying CAPTCHAs!). The only requirement to the end user is

Demo Site is a simple module that allows you to take a snapshot of a Backdrop
demonstration site. It turns a Drupal installation into a sandbox that you can
use for testing modules or publicly demonstrating a module / extension / theme
(you name it). In short: With cron enabled, the Drupal site will be reset to

This module implements the Porter-Stemmer algorithm, version 2, to improve
English-language searching with the Drupal built-in Search module. Information

This simple module allows you to specify some additional attributes for menu
items such as id, name, class, style, and rel.

You should use this module when:

Authored Timezone allows you to specify a custom timezone for the 'Authored on'
field. This is useful when content is written in different timezones. Each piece
of content can display its authored/submitted/created date in the timezone from
which it was written. You can also, optionally, display the author's country in
the 'Submitted' information.

Allows administrators to inject CSS into the page output based on configurable
rules. It's useful for adding simple CSS tweaks without modifying a site's
official theme -- for example, a 'nighttime' color scheme could be added during
certain hours. The CSS is added using Backdrop's standard backdrop_add_css()
function and respects page caching, etc.

The Block Embed module provides a simple UI allowing people to place a single
block in the middle of body copy, a specified number of paragaphs from the top.

Configuration options are included for:

Clears specific Webforms from the database after a selected period
(immediately upon submission or 1,7,30, 60, 90, 365 days).
Any uploaded files associated to the Webform will also be
deleted.

This can happen either never, immediately, or after a selected
period. A default value for the clearing period can be set both site
wide basis, and per Webform.

The Node Reference URL Widget module adds a new widget to the Node Reference
field type. It auto-populates a node reference field with a value from the
URL, and does not allow this value to be changed once set.

Automatically close (set to read-only) comments on content types of your choosing.

It closes the comments when cron runs. Runs once daily, weekly, monthly or annually to close comments more than a week, month or year old.

Port to Backdrop of the UI functionality of Drupal's Entity API.
Provides an administrative interface for managing entities defined in
hook_entity_info().
