The short answer
Both sides assessedCronofy compared with Koalendar
Not competitors in any real sense, and worth stating plainly to avoid a bad purchase. Koalendar is a $6.99 per seat booking link for a person who wants others to book time. Cronofy starts at $819 a month for a developer API. If you are choosing between them, you have misdiagnosed your problem: one of the two is obviously right and it is almost always Koalendar.
Koalendar compared with Cronofy
Different purchases entirely. Cronofy sells calendar and scheduling infrastructure to developers embedding availability inside their own product, from $819 a month billed annually for the API, plus a Scheduler product at around £12 per seat. Koalendar sells a finished booking page to a person. If you are building scheduling into software you ship, Koalendar is not a candidate; if you just need people to book time with you, Cronofy is absurd overkill.
Choose Cronofy if
Software companies embedding scheduling inside their own product (recruiting platforms, field service software, telehealth, marketplaces, sales tools) who need reliable multi-provider calendar sync and real-time availability without building and maintaining it themselves.
Choose Koalendar if
Freelancers, consultants, coaches, recruiters, and small teams who want a straightforward booking link, need more than one meeting type without paying, and would rather spend $6.99 a seat than $16 for round-robin.

| Starting price | Free developer account, then $819 per month billed annually ($899 monthly) for the Emerging API plan | $0 (Free Forever), then $6.99 per seat per month on annual billing |
| Pricing model | Two separate products. The developer API is priced in tiers by synced accounts, Smart Invites, and Application Calendars, with published per-unit overages and unlimited API calls. The Scheduler team product is priced per dynamically assigned seat, with Scheduler API access only from a much higher tier. | Freemium per-seat subscription with a single published paid tier. A seat can be a person or a bookable resource. Teams of ten or more are quoted rather than published. |
| Free plan | A free developer account for building and testing, rather than a free production tier.

| Setup time | Hours to first API call with a free developer account, days to weeks for a production integration. The variable is how much scheduling logic your own product needs to express, not how hard Cronofy is to call. | Ten minutes. Connect a calendar, set your hours, create a booking page, share the link. Payments add a processor connection and perhaps another ten minutes. |
| Learning curve | Moderate for a developer, impossible for a non-developer. The API concepts (synced accounts, availability rules, participants, Smart Invites, application calendars) are clean once understood, but they are calendar-domain concepts and there is real domain complexity underneath. | Minimal. The product is deliberately narrow and the interface reflects that; anyone who has used Calendly will be productive immediately, and anyone who has not will be productive in an afternoon. |

Strengths and limitations
Cronofy
Strengths
- Solves a genuinely hard engineering problem: multi-provider calendar sync and real-time availability across Google, Microsoft 365, Exchange, Apple, and CalDAV behind one API.
- A free developer account with full API access for building and testing before paying, which is the correct evaluation path for infrastructure and not universal.
- Unlimited API calls on every tier, so the cost model tracks customers rather than traffic and chatty implementations are not punished.
- Published per-unit overage pricing rather than negotiated terms, so growth beyond an allowance can be forecast rather than discovered.
Limitations
- It is developer infrastructure, so nothing works until someone writes code. There is no path from signup to a working booking page in an afternoon.
- Entry pricing at $819 a month makes it categorically unsuitable for anyone who just wants a scheduling link, where sub-$10 products do the same visible job.
- The tier jumps are steep: $819 to $2,399 on the API, and £12 per seat to £589 a month for Scheduler API access, with the higher tiers billed annually.
- The Scheduler product is a separate purchase from the API, which makes the overall pricing story more confusing than it needs to be.
Koalendar
Strengths
- The free plan allows unlimited booking pages and two calendar connections, which is materially more generous than Calendly, HubSpot Meetings, or most rivals at the same price of nothing.
- Round-robin and collective scheduling sit on the $6.99 tier rather than a $16 team plan, which halves the cost of the most common team upgrade in this category.
- Payment collection is broad (150-plus currencies, 20-plus methods, tax and receipts) and Koalendar takes no percentage of its own on top of the processor.
- Seats can be resources as well as people, so meeting rooms and equipment are covered without a second product.
Limitations
- No inbound routing forms or lead qualification, so a sales team that needs to disqualify and route by answer needs Calendly Teams, OnceHub, or Chili Piper instead.
- No native CRM integrations of consequence; HubSpot and Salesforce logging goes through Zapier rather than a first-party connector with field mapping.
- The integration catalogue is small in absolute terms, and Zapier or Make carries most of the load.
- No SSO or enterprise identity tier on the published plans, which will stop it in procurement processes that require one; SOC 2 Type 2 is stated but HIPAA support is a paid add-on.
Pricing compared
Cronofy
Two separate products. The developer API is priced in tiers by synced accounts, Smart Invites, and Application Calendars, with published per-unit overages and unlimited API calls. The Scheduler team product is priced per dynamically assigned seat, with Scheduler API access only from a much higher tier.
- Developer account$0
- Emerging (API)$819
- Growth (API)$2,399
- Scheduler (team product)About £12
Judged against building it yourself, Cronofy is straightforwardly cheap. A competent engineer will spend months getting Exchange, Google, and Microsoft 365 availability correct, and will then spend years maintaining it as providers change behaviour. Emerging at about $9,800 a year is a few weeks of that engineer's time. Judged against other products in this category, it is expensive by a factor of twenty, because it is not competing with them: nobody chooses between Cronofy and Koalendar. The honest caution is the shape of the curve. The jump from $819 to $2,399 is steep, the Scheduler API jump from £12 per seat to £589 a month is steeper, and a startup should model synced-account growth carefully before committing annually. Get the free developer account, build the integration, and let real usage tell you which tier you belong on.
Koalendar
Freemium per-seat subscription with a single published paid tier. A seat can be a person or a bookable resource. Teams of ten or more are quoted rather than published.
- Free Forever$0
- Pro$6.99
- TeamsCustom
Koalendar is the best-value personal booking link for anyone who needs more than one meeting type. The free plan is genuinely usable long term (unlimited pages, unlimited bookings, two calendars, embedding, 30-plus languages) which makes it the correct recommendation for most solo users who would otherwise pay Calendly $10 for the privilege of a second event type. Pro at $6.99 a seat buys round-robin and collective scheduling that Calendly charges $16 for, plus payments with no vendor cut. What you give up is enterprise credentials, a deep integration catalogue, CRM logging, and the brand recognition that makes a Calendly link feel unremarkable to a stranger. For a small team, that is a very good trade.
Editorial verdict on each
Cronofy
Cronofy is the only product in this category that is not competing with the others, and buying it by mistake would be an expensive error. It is calendar and scheduling infrastructure for software companies: one API across Google, Microsoft 365, on-premise Exchange, Apple, and CalDAV, with real-time availability, multi-participant and sequenced scheduling, and Smart Invites, backed by a free developer account and published per-unit overages. If you ship a product where two parties need to find a time, that is a genuinely hard problem you should not solve yourself, and $819 a month for the entry tier is a few weeks of engineering a year. The cautions are the steep tier jumps ($819 to $2,399 on annual billing, $899 to $2,669 monthly), the confusing separation between the API and the Scheduler product, and the fact that a Google-only product does not need any of it yet. Build against the free developer account first. And if what you actually wanted was a link people could click to book a call, close this page and read the Koalendar or SimplyMeet.me profile instead.

Koalendar is the right recommendation for anyone whose objection to Calendly is the price of a second event type. The free plan is genuinely complete for a solo user, with unlimited booking pages, unlimited bookings, two calendar connections, embedding, and 30-plus languages, and Pro at $6.99 a seat delivers round-robin and collective scheduling that Calendly charges $16 for, plus payments with no vendor cut. What you are giving up is real but narrow: no routing forms, no first-party CRM connectors, no SOC 2, no API, and none of Calendly's brand familiarity when a stranger clicks the link. If you are a freelancer, a coach, or a team of three or four fielding inbound calls, buy this and spend the difference elsewhere. If your scheduling has to log into Salesforce, qualify leads, or survive a security review, it is the wrong tool and you should stop reading here.
