How we got here

It's 2020. Someone shares a webinar link that works in Gmail but breaks in Outlook. Half the attendees can't add it to their calendars. That frustration sparked what became Calndr.link — and eventually, AddCal.

The problem

Calendar links break across platforms. Timezones get mangled. Half your audience never adds the event. You're left guessing who's actually coming.

Calndr.link

A weekend hack that proved universal calendar compatibility wasn't just possible — it was necessary. One link, every calendar app. Thousands of users agreed.

AddCal

Calndr.link grew up. Same rock-solid core, now with RSVPs, subscription calendars, embeddable widgets, automation, and analytics. Every Calndr.link URL still works.

What we promise

We're not here to "disrupt" anything. We just want to make sharing events dead simple.

Free forever (really)

Unlimited calendar links and adds on every plan, including free. We make money from teams who want premium features — not from individuals sharing events.

We actually listen

That feature you suggested in a random email? We probably built it. We read every piece of feedback because you use this thing more than we do.

Human support

No chatbots, ever. When you need help, you talk to someone who can actually fix your problem — and probably relate to it.

Built for reliability

Your events are too important for "oops, the server went down."

99.9% uptime

Runs on AWS serverless infrastructure. Zero unplanned downtime in 18 months. Your links work when your audience clicks them.

Every link still works

We've never broken a link since day one. Even old Calndr.link URLs still resolve perfectly.

Transparent pricing

No hidden limits. No surprise caps mid-campaign. What you see on the pricing page is what you get.

Trusted by enterprises

IBM, Cisco, Stanford, MIT, Deloitte, SAP, and thousands of teams rely on AddCal daily.

What Our Users Say

Trusted by event organizers worldwide

Rachel Kim
Rated 5 out of 5 stars

Our attendance rate for our funnel events was about 35%. Replaced the ICS download in our confirmation page and emails with an AddCal link and we're above 60% now. Took maybe 10 minutes to set up.

Rated 5 out of 5 stars

Parents kept missing school events because nobody checks the website. We connected our School Management Platform to AddCal and now there's a public page they can subscribe to.

Rated 5 out of 5 stars

We do a weekly tech webinar and used to have a whole separate tool just for RSVPs. AddCal handles that plus the calendar link so it's one less thing to maintain.
