CareersHUB – Job Application Tracking System SaaS
CareersHUB – Job Application Tracking System SaaS is a complete, production-ready web application that enables job seekers to efficiently track and organize their job applications. Built with Next.js 14 and TypeScript, this application provides a comprehensive job search management system with AI-powered features to help users land their dream jobs faster. The platform features a modern, responsive design and includes everything needed to run a job search assistant service, from user authentication to payment processing and AI-powered resume analysis.
This application integrates with several third-party services that charge fees based on usage:
- OpenAI – Charges per AI request for resume reviews, job matching, and cover letter generation. Costs vary based on the AI model selected (GPT-3.5-turbo or GPT-4o-mini) and the complexity of the request. You pay directly to OpenAI for each AI feature used.
- Stripe – Charges a transaction fee of 2.9% plus $0.30 per successful payment transaction when users purchase subscription plans.
- MongoDB Atlas – Free tier available for development, but production use requires a paid plan based on storage and usage.
- NextAuth (Auth.js) – Open-source authentication solution with no direct costs, but requires hosting infrastructure.
You are responsible for all costs associated with these external services. The purchase price of this application includes only the source code and does not include any API credits, service subscriptions, or usage fees. Before deploying this application, please review the pricing pages of all required services to understand the costs you will incur based on your expected usage volume.
While many services offer free tiers suitable for development and testing, production use will require paid plans. Ensure you have budgeted for ongoing API costs based on your expected user base and usage patterns.
