Free Tennis Court Booking Software: What $0 Gets You
Free tennis court booking software exists, and for a one- or two-court club or a volunteer ladder it is often the right choice. Free rarely means unlimited, though: the cost usually moves to a court cap, a per-booking fee charged to players, card processing, or your own time if the system is open source and self-hosted. The useful question is which of those you are paying, and when it starts costing more than a paid plan.
This guide covers what a free tennis booking system has to do, the four places free usually hides a cost, what open source really involves, the free and low-cost plans published in October 2026, and the signs a club has outgrown them.
What a free tennis booking system still has to do
Tennis has fewer moving parts than a multi-sport club, but the basics have to work every time: members see open courts, reserve without double-booking, cancel without emailing anyone, and get a confirmation they trust.
- Real-time availability so two people cannot book the same court
- Self-service booking, cancelling and rescheduling
- A member list, even an informal one
- Recurring holds for a weekly ladder or clinic
- Confirmations and reminders
The four places free usually hides a cost
A free tool is a business too, so the money comes from somewhere. Knowing where tells you what you are signing up for, and it is worth checking before you commit a season's bookings, because switching mid-season is harder than choosing carefully.
- Per-booking or convenience fees charged to players at checkout
- Caps on courts, members or bookings that force an upgrade mid-season
- Ads or upgrade prompts shown to your members
- Support limited to help articles when a Saturday booking goes wrong
Open-source tennis court booking systems: the real cost
Open-source and self-hosted booking systems have no licence fee, which is why they draw a lot of searches. The software is free; running it is not. Someone has to host it, keep it updated and patched, back up member data, connect a payment processor and make sure card data is handled to PCI standards, and fix it when it breaks on a busy morning.
For a club with a volunteer who builds software for a living, that can be a sensible trade. For most clubs, the hours spent on hosting and payment integration cost more than a paid plan within the first season. Before choosing a self-hosted system, write down who maintains it, what happens when that person leaves, and how members will pay.
Free and low-cost plans published in 2026
As of 28 October 2026, Courtlines Free is $0 with no time limit for up to 2 courts at 1 location. YourCourts, which lists tennis among its sports, offers a 30-day free trial, then Lite at $25 a month ($225 a year) for up to 2 courts and Standard at $44 a month for up to 4. CourtReserve's cheapest published plan is $199 a month with 8 courts included. Card processing is extra in every case.
When free genuinely works
A new club with one or two courts, a volunteer-run ladder with no paid staff, or a group organising informal round robins can run on a free tool and never feel the limits. If nobody collects dues, nobody runs a pro shop and the person managing bookings does it on the side, free is the right level of tool.
When a tennis club has outgrown free
The trigger is operational pain, not ambition. If any of these happen most weeks, free is costing more than it saves.
- You collect dues or court fees and track them in a payment app thread
- You run three or more courts and resolve conflicts by hand
- Clinics fill and nobody backfills cancellations from a waitlist
- Lessons, stringing or a pro shop have added a second and third system
- Someone spends real hours each week reconciling bookings and payments
What Courtlines Free includes, limits included
Courtlines Free is $0 a month with no time limit and no platform fee for up to 2 courts at 1 location. It includes real-time court booking, membership basics, point of sale with payments at Stripe's standard rates, and a weekly AI advisor summary. The limits are the court cap, one location and a weekly rather than nightly advisor; the $99-a-month Club plan removes the court cap and adds the nightly advisor and AI campaign composer. Upgrading keeps your existing members, bookings and data.
Questions worth asking
Is there free tennis court booking software?+
Yes. Courtlines Free is $0 with no time limit for up to 2 courts at 1 location. YourCourts offers a 30-day free trial and starts at $25 a month for up to 2 courts. Card processing is extra in both.
Is open-source tennis booking software really free?+
The licence is free; hosting, updates, backups, payment integration and support are not. Unless a volunteer can maintain it reliably, those costs usually exceed a paid plan within a season.
Do free tennis booking apps charge per booking?+
Some charge players a per-booking or convenience fee even when the club pays nothing. Look for the words 'booking fee' or 'transaction fee' on the pricing page and ask in writing.
Can a tennis ladder run on free software?+
Yes. A volunteer ladder needs court scheduling, a player list and results, none of which require membership billing or paid automation.
What happens when a club grows past 2 courts on Courtlines Free?+
It moves to the Club plan at $99 a month per location, which removes the court cap and adds the nightly AI advisor and AI campaign composer. Members, bookings and data carry over.
