The best add to calendar generators, ranked.
We scored every major tool on seven weighted criteria: calendar coverage, features, ease of use, API, analytics, privacy and price.
Quick verdict
Every conclusion on this site comes from our own independent research. We tested each tool hands-on and cross-checked the results against multiple sources: official vendor documentation, published pricing pages, changelogs, source code for the open-source options and public user reviews. No tool pays for a ranking position. Read the full methodology.
Ranking
Best overall
CalendarLink
The most complete add to calendar link generator.
CalendarLink is built around one idea: a single link that works everywhere. Paste it in a newsletter, on a landing page or in a social post and recipients can save the event to Google Calendar, Apple Calendar, Outlook, Office 365 or Yahoo in one click. On top of the links you get hosted event landing pages, subscribable calendars for recurring series, and per-calendar analytics that show exactly how many people added your event and where. The editor is the fastest we tested: a working link takes under a minute. The API lets developers generate links programmatically for booking confirmations, webinars and ticketing flows. For email marketers the plain hosted links are a decisive advantage: no JavaScript, so they work in every email client.
9.6Read reviewBest for larger event programmes
AddEvent
Established add to calendar platform with RSVP features.
AddEvent is one of the longest-running players in this space and it shows in the breadth of the product: add-to-calendar buttons and links, embeddable calendar widgets, subscription calendars and a built-in RSVP system that collects attendee responses alongside the calendar add. That makes it a sensible choice for organisations running large event programmes that need registration and calendar adds in one tool. The trade-offs are cost and flow: pricing scales with usage and climbs quickly at higher volumes, and the editor takes more steps than newer competitors to reach a finished link. Analytics and an API are included on paid plans, and the links are email-safe.
8.9Read reviewBest for website buttons
Add to Calendar PRO
Hosted version of the popular open-source button.
Add to Calendar PRO is the hosted, commercial sibling of the popular open-source add-to-calendar-button. It keeps the polished, highly customisable button that made the open-source project a developer favourite, and wraps it in a no-code editor, hosted event pages and managed delivery, so marketing teams can use it without touching code. The product is EU-based and puts privacy front and centre, which matters for GDPR-conscious organisations. Its focus is clearly the on-site button experience: it covers all major calendar apps and offers email-safe links, but analytics and automation options are thinner than with CalendarLink or AddEvent. If your main use case is a beautiful button on your website, this is a strong pick.
8.7Read reviewBest for events with RSVP and reminders
CalGet
Modern add to calendar links with RSVP and reminders.
CalGet positions itself as more than a link generator: alongside add-to-calendar links for Google, Apple, Outlook, Office 365 and Yahoo, it offers RSVP forms, attendee management and automated email reminders, so it doubles as a light event-registration tool. The editor is modern and quick, and the generated links are email-safe. Where it falls short of the top of this ranking is depth: analytics are more basic, the API and integration options are narrower, and calendar subscription features are less developed than with CalendarLink or AddEvent. For organisers who want RSVP and reminders in the same flow as the calendar add, it is a strong, good-value choice.
8.4Read reviewBest for simple shareable event links
AddCal.co
Straightforward add to calendar link generator.
AddCal.co focuses on the core job: turn an event into a shareable add-to-calendar link that works across Google, Apple, Outlook and Yahoo, with a simple hosted event page around it. The flow is fast and friendly, the links work in email clients, and pricing is accessible for small teams and creators. The simplicity is also the limit: there is no subscribable calendar feature, analytics are minimal, and there is no meaningful API for generating links programmatically at scale. If you need a clean link for a webinar, meetup or launch without a learning curve, AddCal.co delivers; teams needing tracking and automation should look higher up this list.
7.6Read reviewBest free option for developers
add-to-calendar-button (open source)
Free JavaScript web component for developers.
The add-to-calendar-button project is a free, open-source JavaScript web component maintained on GitHub. You drop it into your own site, configure the event in JSON, and visitors get a clean dropdown covering Google, Apple, Outlook, Yahoo and more. Because everything runs client-side there is no account, no tracking of your visitors and no recurring cost, a big plus for privacy. The limitations follow from the same design: it is a button, not a link service, so it cannot be used in email campaigns, and there are no hosted landing pages, no analytics dashboard and no REST API for generating links at scale. It is the right choice when you have development capacity and only need on-site buttons.
7.2Read reviewBest for a quick one-off link
Calndr
Simple free link generator.
Calndr is the lightweight option in this list: a simple web form where you enter a title, date, time and location, and get back add-to-calendar links for the major calendar apps. For a single one-off event, a webinar invite or a save-the-date, it does the job in seconds and costs nothing. What you give up is everything around the link: there is no event management dashboard, no subscribable calendars, no meaningful analytics and only a limited API, so updating an event means generating and redistributing new links. Teams that send calendar invites regularly will outgrow it quickly, but as a free quick-fix tool it is hard to fault.
7.2Read reviewBest if you want zero tools
Manual ICS file + Google link
Do-it-yourself with an .ics file and a Google Calendar URL.
The do-it-yourself route needs no tool at all: Google Calendar has a documented template URL format, and every other calendar app opens a standard .ics file (RFC 5545). Hand-build one of each, host the .ics on your own server, and you have full control with zero third parties and zero cost. In practice this approach is fragile: time zones and daylight-saving transitions are easy to get wrong, special characters need careful URL encoding, and you must maintain a separate link per calendar app instead of one universal link. There is also no way to update the event after sending, and no analytics of any kind. Reasonable for a single internal event; risky for anything customer-facing.
