FitForge — Gym & Fitness Studio Management Platform

Technology Used

Running a gym is straightforward. Billing is manageable. Attendance is trackable. Classes are schedulable. But building software that handles all of it without breaking when 300 members hit it on Monday morning — that is the hard part. FitForge is that software, and it is ready to ship.

This is a production-grade gym and fitness studio management platform built with a Django REST backend, a Next.js admin dashboard for owners and staff, and a Flutter mobile app for members. It covers the full operational surface of running a gym: memberships, billing via Razorpay, QR-based attendance, class scheduling, diet plans, progress tracking, trainer management, and WhatsApp notifications. You buy it, deploy it, and brand it as your own. Your gym clients use your product.

What This Product Does

For Gym Owners and Staff — Web Dashboard

The admin dashboard is where gym operations actually happen. Owners get full control: create and manage membership plans, oversee member accounts, monitor attendance in real time using QR scanning or manual check-in, assign diet plans, and track renewal alerts for expiring memberships. Trainers get a scoped view — they see their assigned members, manage class schedules, and track individual progress logs. Staff can handle day-to-day operations without touching billing configuration or system settings.

For Members — Flutter Mobile App

Members download the app, log in with their phone or email, and get instant access to their membership status, attendance calendar, class schedule, assigned diet plan, and progress charts. They can book or cancel classes, pay for membership renewals directly through Razorpay, scan or show their QR code at the gym entrance, and log their own body metrics over time. The app is built on Riverpod with a clean Obsidian Gold theme — deep black backgrounds, gold accents — and performs fast on both Android and iOS.

Payments and Billing

Razorpay handles all transactions. Members can renew their subscriptions from the mobile app. Staff can process renewals from the dashboard on behalf of members. The platform supports both live and test mode, plus a full mock mode that works without any gateway credentials — useful for demos and local development before you go live.

Who This Is Built For

Gym and Fitness Studio Owners

If you own a gym, a crossfit box, a yoga studio, or a boutique fitness space and you are tired of managing members in spreadsheets or paying recurring SaaS fees for software you do not fully control — FitForge gives you the full stack. White-label it, deploy it on your server, and stop paying per-member fees forever.

Fitness Tech Startups

Building a fitness management product from scratch takes months. FitForge compresses that to days. You get a working backend, a polished admin panel, and a mobile app, all in one purchase. Customise the branding, extend the feature set, and launch your product without writing boilerplate authentication, billing integration, or attendance logic.

Software Agencies Serving the Fitness Industry

If a gym client comes to you for a management platform, you have two options: quote three months of custom development, or deploy FitForge with their branding in a week. The second option wins deals. CodeAj's product customization and white-labeling service can handle the branding work for you if needed.

SaaS Founders Targeting Gym Chains

FitForge's multi-tenant lite architecture is already scoped per gym. Extending it to a full multi-tenant SaaS — where each gym chain is an isolated tenant — requires extending the existing queryset scoping, not rewriting the platform. The foundation is there.

Real-World Applications and Use Cases

A standalone gym in a metro city replaces their paper attendance register and WhatsApp-based renewal reminders with FitForge. Members check in with QR codes. The owner gets an expiry alert dashboard. Renewal income becomes predictable.

A fitness franchise with five locations deploys one instance per location, each with their own data and admin staff, under a shared parent domain. No per-seat SaaS fees. Total infrastructure cost is one VPS per location.

A fitness tech startup acquires FitForge, rebrands it as their own product, adds a custom workout logging module, and launches to their first hundred gym clients within four weeks of purchase.

An agency building for a yoga chain uses FitForge as the base layer, swaps out the attendance module for a booking-first flow, recolors the dashboard, and ships to the client in two weeks instead of three months.

Why Buy This Instead of Building It

Building what FitForge already has from scratch — authentication, role-based access, billing integration, QR attendance, class scheduling, mobile app, and WhatsApp notifications — takes a senior developer at minimum four to five months. At market rate for a full-stack developer in India, that is roughly ₹4 to ₹6 lakh in development cost before you have written a single line of business logic. You also pay that cost every time you need a new feature or a bug fixed.

FitForge is priced at a fraction of that. You get the complete source code, the documentation, and optional deployment support. The money you save in the first month covers the purchase. Every month after that is pure margin.

If you need changes specific to your business — different billing flows, extra roles, a custom reporting layer — the customization service at CodeAj Startup handles it. You describe what you need, we scope and build it on top of the FitForge codebase you already own.
