As answered by people managing SEMRush and ADDCAL.
ADDCAL's answer:
Laravel on Laravel Vapor (AWS Lambda), a Vue.js front end, Cloudflare, PostgreSQL on PlanetScale, and Stripe for billing.
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.
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.
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.
ADDCAL's answer:
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.
