  • Custom Domains & Branding
    Serve links from your own domain and remove AddCal branding
  • Developer-focused positioning
    The .dev domain and branding suggest a tool built for developers and technical teams, so its workflows are likely to fit engineering needs better than a generic product. I could not browse the site, so this is inferred from its positioning rather than confirmed.
  • Graph-based approach
    The name 'Digraph' (directed graph) suggests it models information as connected nodes and relationships. That kind of structure can make dependencies, ideas, or decisions easier to see than flat lists or documents. Confirm how the product actually uses this.
  • Modern, minimal presentation
    Newer developer tools tend to have lean interfaces and a focused feature set, which can mean a short learning curve and less clutter. I could not verify this for Digraph, so check it with a trial.
  • Potential for better organization and clarity
    If the tool works as the name suggests, visualizing relationships between items can improve shared understanding across a team. The benefit depends on how well the product is executed.
  • Early-stage responsiveness
    Smaller or newer products often respond quickly to user feedback and let users influence the roadmap. This is a general tendency and has not been verified for Digraph.

Questions & Answers

As answered by people managing ADDCAL and Digraph.dev.

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.
