How I Built a Smart Shopping Tracker That Saves Users Money

Why i created Salespy: Solving the Smart Shopping Problem
Programming is awesome, but I’ve always wanted to go all the way – from an idea to a working product that actually brings value. That’s how Salespy was born – a service for tracking discounts on Amazon, Walmart, Target, and The Home Depot.

At first, I thought one marketplace would be enough, but it turned out users needed more powerful features to enhance their shopping experience. The workload grew a bit more than I expected – no killer features, no way forward.

Competitor analysis: How Salespy stands out
There are already several well-known price tracking tools on the market, but each comes with significant drawbacks:

Keepa – A powerful tool with a massive price history database, but its interface is outdated and difficult to navigate. Plus, it only supports Amazon and is not available in all countries.
CamelCamelCamel – Similar to Keepa, but some users report price history manipulation, which raises trust issues.
Honey – Primarily focuses on coupon savings rather than full-scale price tracking.

What problems did i want to solve?

Modern and user-friendly interface – No clutter, only the features you actually need.
Multi-marketplace support – Tracks discounts across Amazon, Walmart, Target, and The Home Depot.
Global availability – Works in all countries where these marketplaces operate.
Browser extensions & mobile apps – Seamless tracking, anytime, anywhere.
Advanced features for more accurate and efficient price tracking.

Salespy isn't just another price tracker - it's a smarter, faster, and easier way to save money!

How Salespy works: Tech stack and architecture
To start, I chose:

Next.js (it was a SPA at first, but SEO let me down)
TypeScript
NestJS – in my opinion, the best framework
Redis + BullMQ + MySQL
Nginx

And in the future, I’ll need:

Python
Dart + Flutter

At the beginning, I made a mistake. I decided to go with SPA + Helmet, thinking it would be fine for the early stages, but SEO was terrible. I had to quickly rewrite the public pages in Next.js, and that really helped.

First mistakes and promotion

There were more tasks than I could handle on my own, and as a result, I lost 7 registrations due to a poorly tested release.
It’s hard to attract users without a trial period. Had to add that.
Marketing takes more time than coding. It's something new and a challenge.

I’m still actively working on the project.

Upcoming Features: What’s Next for Salespy?

New marketplaces
A new price update mechanism – faster, more accurate, and scalable
Plugins, mobile app

Real savings: One of the users saved $226.03 just by receiving a timely notification from Salespy.

Why I Started Developing Salespy and What’s New in the Latest Update

Oleksii Khamutinnikov — Thu, 06 Feb 2025 14:13:06 +0000

When my wife and I often shop on Amazon, we’ve noticed that we sometimes miss out on great deals. There are several reasons for this: we forget about sales, we don’t receive notifications about discounts, and we also encounter situations where sellers raise prices before sales and then offer them as discounts. This is not only frustrating but also time-consuming.

We all have a lot going on, and we can’t spend our time constantly checking prices on products. We want to spend more time with family, travel, pursue hobbies, and simply enjoy life. But monitoring prices and looking for discounts is clearly not at the top of our list of priorities.

That’s why I decided to create Salespy. There are various services that try to solve this problem, but many of them didn’t work for me. Some have limited features, others have outdated designs, and some don’t have mobile apps or the features I need. One advantage of similar services is the accumulated price history over a long period, but personally, I don’t think this is crucial — tracking changes over a shorter time is enough.

Salespy is my vision of a modern service for price tracking that will save not only money but also time. We offer a simple, user-friendly interface, price change notifications, and the ability to track products from Amazon in different countries — now you can track products not only from Amazon US but also from other countries where Amazon operates. This is an important update that makes the service even more versatile.

We continue to improve the service and plan to add even more features to help you save both time and money. Salespy is just taking its first steps, but we’re already ready to offer users a convenient tool for tracking discounts and prices.

We’re here to help you save so you can have more time for the things that truly matter!

If you have any questions or suggestions, let's discuss them in the comments or on social media. We are always happy to hear your feedback and ideas!

Salespy: The Future of Smart Shopping Needs Your Support!

Oleksii Khamutinnikov — Thu, 30 Jan 2025 18:07:46 +0000

Are you tired of spending endless hours searching for discounts, tracking prices manually, and switching between multiple marketplaces? Salespy is here to revolutionize the way you shop, and we need your help to take it to the next level!

What’s Next for Salespy?

Salespy is already helping smart shoppers track prices and save money by monitoring Amazon, with plans to expand to Walmart, Target, and The Home Depot. But we don’t want to stop there! Here’s what we’re working on next:

AI Shopping Assistant: Imagine having a personal shopping consultant who helps you find the best deals, recommends the right size, and answers all your product-related questions.
Faster Price Updates: Currently, we update prices once per day. With additional funding, we can improve our infrastructure to track prices more frequently, ensuring you never miss a short-lived discount.
More Notification Options: Right now, users receive email alerts, but we’re planning to add notifications via SMS, browser push, and mobile apps.
Mobile App & Browser Extensions: Our website is just the beginning! We want to make price tracking even more convenient by bringing Salespy directly to your smartphone and browser.
Price Comparison Across Marketplaces: Why settle for one store when you can compare prices across multiple retailers and always get the best deal?

The Challenges & How You Can Help

Building and scaling a project like Salespy is no small feat. As a solo developer with limited resources, I’ve brought the platform to life, but I need the support of the community to truly make it great. Here are the biggest challenges:

Infrastructure Scaling: More users and frequent price updates require additional servers and a more efficient data-fetching mechanism. Your support will help cover server costs and speed up price tracking.
No Free Trial Yet: Right now, Salespy doesn’t offer a free trial due to financial constraints. With funding, we can implement a trial period so users can experience the full benefits before subscribing.
Feature Development: There are so many great ideas for improving the platform, but development takes time. Support will allow for faster implementation of critical features like AI assistance and price comparison.
Marketing & Outreach: The best tools are useless if people don’t know about them! A portion of the funds will go towards spreading the word and reaching more users who could benefit from Salespy.
