Add to Calendar Button vs NetterTech Events

Make your events get saved. This WordPress plugin lets you create beautiful buttons with calendar links, where people can add events to their calendars. All of this with just a few clicks and highly customizable, using the popular Add to Calendar Button script. Check out the official website for a comprehensive demo and overview. 🛠️ INTEGRATED IN SECONDS You can either use the shortcode [add-to-calendar-button] or the Gutenberg Block. With the PRO version, it only takes the ID to make it fly. In the no-PRO case, you simply place the necessary attributes directly in the shortcode, or at the Gutenberg Block settings. (Mind that you cannot use ‘[‘ and ‘]’ characters, when going for the shortcode option! For content formatting, you can use {‘{‘}xxx{‘}’} instead of [xxx] there.) 🚀 GO PRO Go even further with the PRO version… → Manage all details and styling via a convenient web app. → Use the same button to let people RSVP to your events – fully managed. → Get auto-generated landing pages and shareable links for your events. → Have better guidance for your users, when they add events to their calendars and things don’t go as expected. 👉 Learn more at add-to-calendar-pro.com. ✨ SUPPORTED CALENDARS Google Calendar. Yahoo Calender. Microsoft 365, Outlook, and Teams. Automatically generated iCal/ics files (for all other calendars, like Apple). 📆 SUPPORTED EVENT TYPES Timed and all-day events. One-time, multi-date, recurring. Most robust time zone and daylight saving management. Dynamic dates (like “today + 3”). 🎨 ADJUST THE LOOK The button comes with multiple themes as well as a dark and light mode. You can easily adjust almost every element by setting the respective simple attributes. In case you want to go all-in, you can also manipulate all kinds of colors and further styling. 🖖 EXPERT ACCESSIBILITY Optimized and adjustable UX (for desktop and mobile). Dynamic dropdown positioning. Taking care of all those edge cases, where some scenarios do not support specific setups (like WebView blocking downloads); utilizing beautiful user guidance workarounds. Auto-generated Schema.org rich (structured) data for better SEO. Full support for mouse, touch, or keyboard input (W3C WAI compliant). Aside from the WordPress editor, the button itself supports 20+ languages, incl. RTL text for Arabic; but also offers the option to customize all labels and text blocks. 📄 ABOUT THE LICENSE Mind that the script to actually generate the Add to Calendar Button uses the Elastic License 2.0 (ELv2)! This usually comes with no restrictions for you, but it forbids you to rework the core script and provide the product (generating an add-to-calendar-button) to others as a managed service. In almost every case, this will not affect you. If you are not sure, because you are building some kind of SaaS, where you are using the plugin, simply contact us.

NetterTech Events stores your events in dedicated database tables rather than WordPress post meta. That architectural choice means calendar queries stay fast whether you have 50 events or 5,000, and it means recurring event schedules are pre-computed rather than recalculated on every page load. Recurring events that handle real schedules: Full RFC 5545 recurrence rule support covers patterns like “every second Tuesday” and “last Friday of the month.” Change a rule, and occurrences regenerate automatically. Ticketing without per-ticket fees: Sell tickets through WooCommerce with automatic capacity tracking per occurrence. Series passes let attendees buy once for an entire recurring event run. No external ticketing service means no percentage taken on each sale. Free event registration: RSVP forms work without WooCommerce for events that don’t require payment. Attendees register, receive confirmations, and can be tracked through the same admin interface. Check-in built in: Manual attendee check-in by name or email search works from any device. QR code and volunteer check-in workflows can be added with the separate NetterTech Events Pro plugin. Spaces and locations management: Define bookable spaces and physical locations through a dedicated admin interface. Assign spaces to events via the event editor metabox to track which room or area each event occupies. Display options for any layout: Month, week, and day calendar views. Carousel slider for featured events. Filterable grid with live search. Weekly regulars table for recurring events. All three calendar views are available as Gutenberg blocks and Beaver Builder modules. Reminder emails that send themselves: Configure pre-event reminders at any interval you choose. Emails go out automatically via WordPress cron – no third-party service required. SEO handled at the source: Schema.org Event structured data integrates with Yoast SEO and Rank Math’s JSON-LD output rather than generating a second duplicate block. Custom sitemap entries cover recurring occurrence URLs individually. Custom SEO title variables (%%nettertech_events_event_date%%, %%nettertech_events_event_venue%%, %%nettertech_events_event_organizer%%) let you build dynamic titles per-occurrence. Breadcrumb trail follows the full event hierarchy. Works without either SEO plugin using built-in Schema.org and Open Graph output. Accessibility throughout: Designed to WCAG 2.2 AA standards with ARIA labels, full keyboard navigation, focus management, and reduced motion support across every public-facing view. Your data stays yours: All attendee, ticket, and event data is stored in your WordPress database. No data is sent to external services. GDPR tools let site administrators export or erase attendee records on request.

WooCommerce Integration (Optional) When WooCommerce is installed and activated, this plugin integrates with it to provide paid ticketing functionality. WooCommerce is a separate plugin that handles payment processing through payment gateways you configure. WooCommerce is developed by Automattic WooCommerce Terms of Service WooCommerce Privacy Policy No data is sent to WooCommerce servers by this plugin. All ticket and order data remains in your WordPress database. QR Code Generation QR codes are generated entirely on your server using the bundled PHP QR Code library. No external API calls are made. Bundled Third-Party Libraries NetterTech Events is licensed under GPL-2.0-or-later. The plugin bundles the following GPL-compatible third-party libraries via Composer. The authoritative dependency list and resolved versions live in composer.json and composer.lock (both shipped with the plugin so reviewers can verify vendor contents). chillerlan/php-qrcode 6.0.1 — MIT (selected from the upstream dual MIT / Apache-2.0 license). Used for QR code rendering on tickets and check-in flows. Source: https://github.com/chillerlan/php-qrcode chillerlan/php-settings-container 3.3.0 — MIT. Transitive dependency of php-qrcode. Source: https://github.com/chillerlan/php-settings-container symfony/polyfill-mbstring 1.33.0 — MIT. UTF-8 string-function polyfill (transitive). Source: https://github.com/symfony/polyfill-mbstring The MIT license is selected for the dual-licensed chillerlan/php-qrcode because Apache-2.0’s patent-retaliation clause is GPL-3.0+ compatible but not GPL-2.0 compatible. MIT keeps the bundled code consistent with the plugin’s GPL-2.0+ choice.
