Overview

Gym141 combines staff administration with a public website and member portal. Members can check personal data and fee status, RSVP to events, and view progress charts; staff manage member records, fees, schedules, and editorial pages. That breadth can spare a club from coordinating separate tools, though clubs without a compatible host should look to a hosted service instead.

The software is released under the MIT license. Installation requires PHP 8.1 or newer and SQLite. A browser-based installer configures the database and admin area, and one-click updates include backups and protected files. The maker says no Composer or build step is needed, which keeps the deployment process more direct, but the club still needs to provide the web host.

Key features

Member records support search, filters, and exports, with fee plans that handle billing periods, reminders, pauses, and history. Membership freezes and flexible billing frequency help clubs accommodate temporary absences or different payment schedules. Fee payments post automatically to the cash book, reducing duplicate bookkeeping; reports and forecasts add a view of finances beyond the payment record.

The cash book supports categories, payment methods, and fixed costs. The public website includes training groups, a clickable weekly schedule, and editorial pages managed in the backend, making Gym141 more than a staff-only database. AI form scanning can extract registration details from photos or PDFs and pre-fill member records, but it requires the customer’s own Anthropic API key, so it is not a turnkey inclusion for clubs without one.

Pricing

The Free plan costs €0 forever and includes the full feature set for up to 25 active members, with self-hosting, an MIT license, and updates from the site. This is a credible option for a small club that can manage hosting; the member cap, rather than feature access, is the main reason to move up.

Pro costs €14.90 per month and adds unlimited members and a license key, with cancellation allowed anytime. It is the practical step for a club that has outgrown the free cap. Ultra costs €29.90 per month and adds priority support and multi-location support to Pro, fitting operators with more than one site or a need for prioritized help. Both paid plans can be tried free for 30 days once per account, without payment details; prices include VAT and are billed through Stripe in the DevWorld customer portal.

Priority support is also sold separately for €9.90/month. The “Your own app” option costs €999 one-time and provides a branded member app for Android, iOS, and Windows by request only. That is a separate, substantial purchase rather than part of the monthly plans.

Platforms

Gym141 supports Android, iOS, web, and Windows, and is self-hosted. The software’s hosting requirements—PHP 8.1 or newer and SQLite—matter more to deployment than the platform list: clubs need a compatible web host even if members use mobile devices.

Who it's for

Gym141 is best for clubs that want member administration, accounting, a public site, and a member portal in one open-source system, and have the capacity to run a compatible host. Small clubs can start without a software charge; growing clubs can keep the same feature set while removing the active-member cap with Pro. It is a poor fit for operators who want a hosted service with no hosting responsibility.

Pros and cons

Pro: The free plan includes the full feature set, so a club with 25 or fewer active members need not trade away functionality to avoid a subscription.
Pro: Member fees, automatic payment posting, cash-book reporting, public schedule, and member portal cover both club administration and member communication in one system.
Pro: The MIT license and self-hosted model give clubs an open-source option rather than a hosted-only product.
Con: The free plan stops at 25 active members, so a club that grows past that point needs Pro for unlimited members.
Con: PHP 8.1 or newer and SQLite are required, making Gym141 unsuitable for clubs unwilling or unable to manage a compatible host.
Con: AI form scanning depends on the club’s Anthropic API key, adding a separate setup requirement for that feature.

Alternatives

For a broader comparison, see Gym Membership Billing Software. Clubworx is worth considering for a hosted web and mobile option with a free plan capped at 20 active members; its free tier also includes a website, online booking, payment acceptance, messaging, and a self check-in kiosk. Fitnito may suit a smaller program that can work within its free Starter limits of one location, one program, one pass type, five staff members, and two weekly recurring sessions.

Sport School Manager is an alternative for schools that value a paid School Plan at $89 USD/month with unlimited students, priority support, dedicated onboarding, and a 90-day free trial. Gymdesk is a paid alternative with a free trial and a plan at $75 USD per month for up to 50 members. Revel is another self-hosted, MIT-licensed option: its free self-hosted plan has no platform fees or monthly costs, though infrastructure and Stripe processing are paid separately.

BoxBoard is another alternative. FightKit may be a better fit for a martial-arts club seeking a paid option with a free trial; its Starter plan is £19.00 per month. MyStudio is a paid alternative whose Essentials plan is $79.00 USD /mo and includes unlimited students, a website and member app, rank and belt tracking, online sales and payments, and class scheduling.

Verdict

Choose Gym141 if your club wants open-source member, fee, accounting, and public-facing tools together and can handle self-hosting; the full-featured free plan makes it especially compelling below 26 active members. Look elsewhere if hosting is a burden or you need a hosted service, and plan for Pro once the club exceeds the free member limit.
