How I Built a Full-Stack Bus Reservation SaaS in 3 Months (React + FastAPI)

Hey DEV community! 👋

For the past few months, I've been heads-down building a production-ready Bus Reservation SaaS. I wanted to build something beyond a generic "to-do list" app—something with real-world complexity like concurrent bookings, robust admin analytics, and live seat tracking.

Here is a breakdown of what I built and the tech stack I used.

🛠️ The Tech Stack

Frontend: React (Vite) + Tailwind CSS (for that glassmorphism, premium feel)
Backend: FastAPI (Python) - Chose this for massive async performance
Database: MongoDB Atlas
Real-time: WebSockets for live seat locking

✨ Key Features Built

Interactive Seat Selection: Users can see which seats are available, already booked, or currently being held by someone else in real-time.
Dynamic Admin Dashboard: A comprehensive pane tracking total revenue, upcoming bookings, and a massive inventory of routes (over 280,000 seeded!).
QR Generation: Auto-generating QR code tickets via Python upon a successful booking.

📂 Grab the Full Source Code

If you are a developer looking for a template to build a SaaS, or an agency looking to flip this to a travel client, I have packaged the entire source code (Frontend + Backend + Handover Docs).

Since it's my first launch here, I'm doing a huge 40% OFF discount for the first 5 buyers using the code FIRST5.

I built a Real-time Bus Reservation System with React & FastAPI 🚍

Hey DEV community! 👋

"Quick Note: If you want to grab the full source code (React & FastAPI) of this system, you can find it here on [Gumroad ($29)]"

For the past few weeks, I wanted to build something that solves a complex real-world problem. So, I built a complete "SaaS-in-a-box" Bus Reservation platform called Ani Travels.

My main challenge was handling concurrency—making sure two people looking at the same open seat cannot book it simultaneously.

🛠 The Tech Stack

Frontend: React (Vite) + Tailwind CSS + Framer Motion (Added smooth page transitions and interactive seat mapping).
Backend: Python FastAPI (I fell in love with how fast and easy the asynchronous execution is).
Database: MongoDB.
Real-time Locking: WebSockets! As soon as a user selects a seat, an event is fired and the seat is locked across all active sessions instantly.

🌟 Features Implemented

Search bus routes and see results dynamically.
Interactive visual UI for Seat Selection (like MakeMyTrip/Redbus).
Checkout forms and backend payment processing flow.
A fully functional Admin Dashboard to add complete routes, assign buses, and monitor all platform bookings.

You can play around with the Live Demo here:

(Since the backend is on Render free tier, please excuse the initial 50-second cold start!)

I am selling the Complete Source Code along with detailed setup instructions if any entrepreneur or dev wants to skip 100+ hours of coding and launch their own startup/project immediately. It comes with seed scripts to populate DB instantly.

Would love to hear constructive feedback! How do you handle complex booking architectures in your apps?
