The short answer

Both sides assessed

Cronofy 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 around $139 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 $139 a month 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 around $139 per month for the entry API plan (free plan available)	$0 (Free Forever), then $6.99 per seat per month on annual billing (free plan available)
Pricing model	Two separate products. The developer API is priced in tiers by synced accounts, Smart Invites, and Embedded Scheduler seats, 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. Live usage requires a paid plan.	Free Forever includes unlimited booking pages, unlimited bookings, two calendar syncs (Google, Outlook, iCloud), video conferencing links, website embedding, 40-plus languages, and automatic timezone detection.
Free trial	A free developer account allows building and testing against the APIs before any payment	The Free Forever plan is the evaluation path; Pro is also available on monthly billing so you can cancel at the end of any month
Best for	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.	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.
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 around $139 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: $139 to $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 published SOC 2 report or enterprise security package, which will stop it in any procurement process that requires one.

Pricing compared

Cronofy

Two separate products. The developer API is priced in tiers by synced accounts, Smart Invites, and Embedded Scheduler seats, 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
Starter (API)About $139
Emerging (API)About $819
Growth (API)About $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. Starter at around $139 a month is less than a week of that engineer's time per year. 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 $139 to $819 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, 40-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 around $139 a month for the entry tier is less than a week of engineering. The cautions are the steep tier jumps ($139 to $819 to $2,399, all annual above Starter), 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

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 40-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.
