Overview

The package covers both staff operations and member interactions: members can check their personal data and fee status, RSVP to events, and view progress charts. Staff get membership and payment administration alongside a public website with training groups, a weekly schedule, and editorial pages managed in the backend. That breadth can spare a small club from assembling separate tools, though clubs seeking a hosted service should look elsewhere.

Gym141 is open source under the MIT license. It requires a web host running PHP 8.1 or newer and SQLite. A browser installer configures the database and admin area, while one-click updates include backups and protected files. The maker says installation needs no Composer or build step; that simplifies deployment, but the club still needs to provide the compatible host.

Key features

Member records support search, filters, and exports. Fee plans can define billing periods, send reminders, pause membership, and retain payment history; membership freezes and flexible billing frequency help accommodate temporary absences and different payment schedules. The cash book organizes transactions by category and payment method, records fixed costs, and produces reports with forecasts. Fee payments post automatically, reducing the need to enter them again in the accounts.

The public website combines training groups and a clickable weekly schedule with backend-managed editorial pages. The member portal adds self-service access to personal data and fee status, event RSVPs, and progress charts. AI form scanning can extract registration details from photos or PDFs and prefill member records, but it requires the club’s own Anthropic API key, so it is not a turnkey feature for operators without one.

Pricing

The Free plan costs €0 forever and includes the full feature set, MIT-licensed self-hosting, and updates from the site, capped at 25 active members. That is a credible starting point for a small club, but the cap means a growing membership requires a paid plan. Pro costs €14.90 per month for unlimited members and a license key, with cancellation allowed anytime. It is the natural step up for clubs that have outgrown the free limit without needing the extra support and multi-location capabilities of Ultra.

Ultra costs €29.90 per month and adds priority support and multi-location support to Pro. It fits operators managing more than one location or those who value priority assistance. Priority support is also sold separately for €9.90/month, making the add-on a cheaper option for a Pro customer who needs support but not multi-location features. Your own app costs €999 one-time and provides a branded member app for Android, iOS, and Windows; it is available by request only, so it is a separate investment rather than a standard subscription tier.

Pro and all add-ons have a 30-day free trial, once per account, with no payment details required. Prices include VAT and are billed via Stripe in the DevWorld customer portal. DevWorld also identifies itself as a US-based company with an address in Sheridan, Wyoming.

Platforms

Gym141 is self-hosted and web-based, with Android, iOS, and Windows also named as platforms. The branded app is a separate €999 one-time purchase by request. For the core system, PHP 8.1 or newer and SQLite are concrete hosting prerequisites, so it is best for clubs comfortable choosing and maintaining a compatible web host.

Who it's for

Gym141 is a strong fit for small clubs that want administration, member access, accounting, scheduling, and a public site in one MIT-licensed system, especially if they can host it themselves. The free plan makes it accessible up to 25 active members, and Pro removes that membership cap for a monthly fee. Clubs that do not want to arrange hosting, or that want a larger free allowance, should compare alternatives before committing.

Pros and cons

Pros: The full feature set is available on a free, MIT-licensed plan, making it possible to start without a subscription while keeping the option to self-host.
Pros: Member administration, fee handling, accounting, a public site, and a member portal sit in one package, which can reduce the need for separate systems.
Pros: Pro offers unlimited members for €14.90 per month and can be cancelled anytime, a clear path beyond the free plan’s 25-member cap.
Cons: Hosting requires PHP 8.1 or newer and SQLite; clubs wanting a hosted service must choose another option.
Cons: AI form scanning depends on the customer’s Anthropic API key, which adds a separate setup requirement.
Cons: The branded app costs €999 one-time and is by request only, making it a substantial additional purchase.

Alternatives

Gym membership billing software is a useful place to compare other options in the category. Choose Clubworx if you want a free plan capped at 20 active members that also includes a website, online booking, payments, email and SMS, and a self-check-in kiosk. Fitnito is worth considering if a free starter plan with one location, one program, one pass type, up to five staff, and two weekly recurring sessions is a closer match to your operating limits.

Sport School Manager may suit a school operation better: its School Plan is $89 USD/month for unlimited students, priority support, dedicated onboarding, and a 90-day free trial. FightKit is another option to compare. Gymdesk is a paid alternative with a plan priced at $75.00 USD per month for up to 50 members. GymMaster starts with a Foundation plan at $89.00 USD per month for 100 current members, with prices excluding tax and a 10% subscription discount for yearly payment.

BoxBoard is a more limited free option for a very small garage gym: its Basic Garage Gym plan is free forever for up to five members and includes workout scheduling and tracking tools. ManageYourGym is another alternative to consider.

Verdict

Choose Gym141 if you want a broad, open-source club management system, can supply PHP-and-SQLite hosting, and value having member administration, accounting, scheduling, and a public site in one place. Its full-featured free plan is attractive for clubs with no more than 25 active members, and Pro offers an uncapped membership at €14.90 per month. Look elsewhere if self-hosting is a deal-breaker or you need a larger free allowance.
