  • Performance Overhead
    Using a large set of UI components can lead to performance overhead, impacting load times and efficiency, especially in complex applications.
  • End of Updates
    As AngularJS is in Long Term Support (LTS) and will be obsolete soon, Angular UI Bootstrap might not receive significant updates or improvements.

No analysis of ADDCAL yet.

Overall verdict

  • Angular UI Bootstrap was a solid, native AngularJS (1.x) implementation of Bootstrap components that avoided jQuery dependency, making it a good choice historically for AngularJS projects, though it is now largely legacy since it targets AngularJS rather than modern Angular (2+).

Why this product is good

  • Provides native AngularJS directives for Bootstrap components without requiring jQuery or bootstrap.js, resulting in tighter integration with Angular's digest cycle
  • Wide range of ready-made UI components like modals, datepickers, tooltips, accordions, carousels, and pagination that follow Bootstrap 3 styling
  • Highly customizable through Angular templates, allowing developers to override default HTML for each component easily
  • Was widely adopted and battle-tested in many AngularJS 1.x applications, giving it stability and community-vetted code
  • Good documentation with live interactive demos for each component, making it easy to learn and implement
  • Lightweight compared to including full jQuery plus Bootstrap JS, since it only depends on AngularJS core

Recommended for

  • Developers maintaining legacy AngularJS (1.x) applications who need Bootstrap-styled UI components
  • Teams wanting to avoid jQuery dependency in an AngularJS codebase
  • Projects already committed to Bootstrap 3 styling conventions
  • Small to medium AngularJS apps needing quick implementation of common UI widgets like modals and datepickers
  • Not recommended for new projects using modern Angular (Angular 2+), where alternatives like ng-bootstrap or PrimeNG are more appropriate

Questions & Answers

As answered by people managing ADDCAL and Angular UI Bootstrap.

Which are the primary technologies used for building your product?

ADDCAL's answer

Laravel on Laravel Vapor (AWS Lambda), a Vue.js front end, Cloudflare, PostgreSQL on PlanetScale, and Stripe for billing.

What makes your product unique?

ADDCAL's answer

AddCal combines add-to-calendar links, live subscription calendars and RSVPs in one tool, so organisers don't need separate products for each. One link works across Google, Apple, Outlook, Office 365 and Yahoo. Subscription calendars push updates and cancellations to subscribers automatically. Smart Links let developers generate events on the fly from URL parameters, webhooks or Zapier. There's also an MCP server, so AI assistants can create and manage events directly.

Why should a person choose your product over its competitors?

ADDCAL's answer

The free plan includes unlimited calendar adds and subscription calendars, and paid plans are simple monthly or annual tiers with no per-event fees. Every link comes with analytics. Moving from AddEvent takes one click. AddCal is independently built and run, so support comes straight from the people who build the product.

How would you describe the primary audience of your product?

ADDCAL's answer

Anyone who needs people to actually save and attend their events: webinar and SaaS marketers, schools and school districts, universities, local councils, sports clubs, community and faith groups, and event organisers. It's also for developers who add calendar links to apps, emails and booking flows.

Who are some of the biggest customers of your product?

ADDCAL's answer

  • MIT
  • Accenture
  • Deloitte
  • ServiceNow
  • Workday
  • Snowflake
  • Merck

What's the story behind your product?

ADDCAL's answer

In 2020, a webinar invite that worked in Gmail broke in Outlook, and half the attendees couldn't add the event to their calendars. That frustration led to Calndr.link, a weekend hack that offered one add-to-calendar link that worked in every calendar app. Organisers wanted more, so Calndr.link grew into AddCal, which added RSVPs, subscription calendars, embeddable widgets, automation and analytics. Every Calndr.link URL still works. Today AddCal is used by more than 15,000 people and teams in over 120 countries, with more than 25 million calendar adds.
