What's Included
Source code, All related data, All related design work
Yes, I’m including: Documentation: Instructions for setup, deployment, and usage (e.g., how to configure 2Captcha API, Google Sheets API, and MongoDB). API Credentials: I can provide temporary access to 2Captcha and Google Sheets API credentials for testing (to be replaced by the buyer after purchase). Beta User Feedback: Feedback from 10 beta users to help the buyer understand user needs and improve the product.
Reason for Selling
I built LinkSentry as a side project to solve a problem I faced with manual link checking, and I’m proud of the working MVP I’ve created. However, as a solo developer, I lack the time to focus on marketing, user acquisition, and scaling the project to its full potential. I’m selling to find a buyer who can dedicate the resources to grow LinkSentry into a leading tool in the SEO and marketing automation space.

Development Context & Timeline
Project Development Timeline
This project was created on April 16, 2025 and last updated on September 10, 2026. The project has been in development for approximately 17.2 months, representing 515.20597429931 days of development time.
Technical Implementation Effort
Implementation Complexity: High - The project uses 16 different technologies (JS React,Framer Motion,Chart.js,Tailwind CSS,Node.js,Express,MongoDb,Mongoose,Puppeteer,2Captcha,Google Sheets API,Axios,Cheerio,JWT,bcrypt,dotenv), requiring extensive integration work and cross-technology expertise.
Next Development Phase: <p>The buyer can take LinkSentry to the next level by deploying it to a cloud platform (e.g., AWS, Heroku, or Vercel) and launching it publicly to attract SEO professionals, marketers, and website owners. With a $10k marketing budget, the buyer could target SEO communities (e.g., Reddit, IndieHackers, SEO forums) and acquire 1000 users in a year, generating $240k in annual revenue ($20/month per Basic plan). Adding features like advanced analytics (e.g., backlink quality scoring), integrations with other tools (e.g., Zapier, Ahrefs API), and support for more CAPTCHAs would make LinkSentry even more competitive. The buyer could also explore partnerships with SEO agencies or offer a white-label solution for marketing teams. The SEO and marketing automation market is growing rapidly (valued at billions), and LinkSentry’s unique combination of Google Sheets integration and CAPTCHA solving positions it to capture a niche in this space.</p>
