The short answer

Both create booking links that show your free time and let people pick a slot. Calendly is the familiar default for sales and client-facing teams, with routing, CRM sync and AI extras, but its free plan allows one event type. Cal.com is open source, can be self-hosted or embedded, and its free plan includes unlimited event types and calendars. Pick Cal.com for value and control, Calendly for familiarity.

Cal.com or Calendly: our take

Calendly made the booking link mainstream, and that familiarity is part of its value: invitees already know how it works. Teams get round-robin and collective meetings, routing forms that qualify leads before booking, Salesforce and HubSpot connections and more than 150 integrations. Recent additions include an AI notetaker, an email assistant called Callie that proposes times in threads, and payment collection. Cal.com started as an open-source answer to Calendly and now covers most of the same ground, including Stripe or PayPal payments and two-way Salesforce and HubSpot sync, plus an API and embeddable components for building scheduling into your own product.

Pricing is where they separate. Calendly's free plan has one event type and one calendar connection, so regular users usually pay: Standard is $10 per seat/month and Teams is $16 per seat/month, both billed yearly, and Enterprise starts from $15k per year with a 50-seat minimum. Cal.com's free plan gives one user unlimited event types. Its Teams plan is $12 per user/month and Organizations is $28 per user/month, billed yearly, with a 14-day trial on paid plans; team features such as round-robin need one of these.

Cal.com's source code is public and it can be self-hosted with Docker, which matters for teams with data residency or customisation needs, though you then maintain the database, cron jobs and upgrades yourself. Its settings area is also busier than Calendly's. Both run in the browser with mobile apps and a browser extension.

Choose Calendly if you run a sales or recruiting team that wants the most recognised booking experience and polished routing. Choose Cal.com if you are an individual who wants a capable free plan, or a team that wants to self-host, embed scheduling or avoid lock-in.

What is Cal.com?

Cal.com started as an open-source answer to Calendly and has grown into a full scheduling platform. Individuals get booking pages with unlimited event types and calendar connections for free, including payments through Stripe or PayPal and two-way sync with Salesforce and HubSpot. Paid team plans add round-robin and collective events, routing forms, managed event types and the option to remove Cal.com branding, while the Organizations tier adds sub-teams, SAML SSO and compliance features such as HIPAA. Developers can embed booking components, use the public API, or run the whole stack themselves from the source code with Docker. The hosted service is priced per user per month with a 14-day trial for paid plans. It works in the browser, with mobile apps and a browser extension. The trade-off for the flexibility is a busier settings area than simpler tools, and self-hosting means you maintain the database, cron jobs and upgrades yourself.

What is Calendly?

Calendly made the booking link mainstream. You connect a calendar, define event types such as a 30-minute intro call, and share a link; invitees see only your free slots and book without any email back-and-forth. Teams get round-robin and collective meetings, routing forms that qualify leads before they book, and CRM connections to Salesforce and HubSpot. Recent additions push it beyond scheduling: an AI notetaker that writes meeting recaps, an email assistant called Callie that proposes times in threads, and payment collection for paid sessions. The free plan is real but narrow, with one event type and one calendar connection, so most regular users end up on a per-seat paid plan; enterprise contracts are sold annually. It runs in the browser with iOS and Android apps and a browser extension. It is the safe default for sales, recruiting and customer-facing teams, though cheaper and open-source tools now match most of its core booking features.
