We make events people actually show up to
AddCal is a calendar sharing platform used by 15,000+ people and teams at companies like IBM, Stanford, Cisco, and Deloitte. One link, every calendar app, zero friction.
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.
Loved by the people who run events.
“Our attendance rate for funnel events was about 35%. We replaced our confirmation page and emails with AddCal links and we're above 60% now.”
“Parents kept missing school events because nobody checks the website. We switched our calendar to AddCal, now it's a public page they subscribe to. Game changer.”
“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.”
