CrossFit Booking System Builder: Capped Classes, Waitlists and Packs

A CrossFit booking system lets members claim a spot in a capped WOD, joins them to a waitlist when it is full, and checks their plan before confirming. Mythex builds one from a description of your timetable, caps and membership rules, with a coach view of who is on the floor today.

Who it's for

Box owners whose class caps are policed in a WhatsApp group, whose waitlist is a coach's memory, and whose drop-ins sign a paper waiver on the bench by the door.

What you can build

A weekly timetable of WODs, open gym, on-ramp and Olympic lifting, each with its own cap
A waitlist that moves the next member in when someone cancels
A late-cancel cut-off with no-show counts per member
Class packs that drop by one per booking, and weekly limits on capped plans
Drop-in booking for visiting athletes, gated on an accepted waiver
A check-in list for the coach, so attendance is recorded as people arrive

What a CrossFit booking system must do

A box books people into classes, not appointments. Each class has a cap set by floor space and coach-to-athlete ratio, and members book against the plan they pay for. The system has to know that a ten-pack member has three classes left, that a three-a-week member already booked Monday, Tuesday and Thursday, and that a visiting athlete from another box needs to sign your waiver first. It also needs to know which coach runs each class, so cover is visible when someone is away.

Waitlists and late cancels

Popular slots fill days ahead, and members who book just in case leave empty spots that waitlisted athletes could have used. Set a cut-off, often one or two hours before class, after which a cancel counts as late. Move the first waitlisted member in automatically when a spot opens and tell them. Track no-shows, and decide early whether repeat offenders lose a pack credit or simply get a word from a coach. A clear rule makes it fair, and members stop gaming the timetable.

Mistakes to avoid

Don't put every class type on one cap; open gym and a barbell club have different limits. Don't let packs live forever unless you mean it, because a forgotten 2023 pack will be redeemed in the middle of the Open. And don't let new members into regular WODs before they finish on-ramp; make on-ramp completion a booking requirement.

What to set up first

Enter the timetable and caps, then the plans and their rules, then the waiver text. Import your member list from a spreadsheet and assign each person a plan. Run the new booking page alongside the group chat for one week, then switch the chat to announcements only.

A prompt to start from

Build a booking system for my CrossFit box. The timetable has WODs at 6am, 7am, 12pm, 5:30pm and 6:30pm capped at 16, plus open gym capped at 10. Members on unlimited, 3-per-week or 10-class packs book against their plan, full classes have a waitlist that auto-fills, cancels inside 2 hours count as late, and drop-ins must accept a waiver first. Add a coach check-in screen for each class.

Questions

Can members book from their phones?

Yes. The booking page works in any phone browser and can be added to the home screen. On Pro, Mythex can also wrap your published app as Android and iPhone apps.

Can it handle class packs as well as memberships?

Yes. Describe each plan and Mythex builds the rules: packs lose one class per booking, weekly-limit plans stop at their limit, and members over it are offered a drop-in.

Does the waitlist fill spots automatically?

It can. When a member cancels, the first person on the waitlist is moved in and notified. You can also choose to have coaches confirm waitlist moves by hand.

Can I block holidays and competition days?

Yes. Mark closures or cancelled classes and they stop appearing. For an in-house throwdown you can replace the normal timetable for that day.

Do I need to know how to code?

No. You describe the timetable and rules in plain language and Mythex writes the app, shows a live preview and takes changes by chat.

How much does it cost?

The Free plan has daily credits and no card, enough to build and publish a first version. Pro is $25 a month for code editing, export, a custom domain and more credits.
