Building “Product Fetcher”: A Solopreneur’s Dive into Scraping, AI, and Automation

Hi devs and indie hackers! 👋

I recently launched Product Fetcher, an API that uses AI to extract product information (like price, description, ratings, etc.) from any web page. No coding, no setup — it just works.

As someone who’s spent hours (maybe days?) struggling with scraping quirks, I wanted to share the tech behind it and what I learned while building this as a solo dev.

Why Build This? 🧐

Web scraping is powerful but messy. Writing custom scripts for each website gets old fast, and dealing with captchas, dynamic JavaScript, and constantly changing layouts is a nightmare.

The goal of Product Fetcher is simple:

Adaptability: The API can handle almost any product page.
Automation: No need for manual configurations or updates.
Ease of Use: Even non-developers can use it via a simple API call.

I wanted to build something that feels like magic — where you send a URL, and the API does the rest.

The Tech Stack 🛠️

Here’s the technical breakdown:

Backend:

Built with Next.js, integrating Puppeteer and Playwright for scraping.

Dynamic Challenges:

Proxy rotation to bypass IP blocks.
JavaScript rendering for dynamic pages.
Captcha solving for protected sites.
Rate limiting to stay efficient and polite.

AI Layers:

A preprocessing layer that transforms and cleans the raw data.
A second layer that extracts clean data, using contextual hints (like related metadata) to make parsing more accurate.

The result? An API that adapts to different layouts, handles edge cases, and keeps improving with every iteration.

Lessons from Building a V0 🚀

This is very much a V0. There’s so much more I want to add: better error handling, more AI optimizations, and maybe even custom scraping templates for specific use cases. But starting small has taught me a lot about balancing features with usability.

For now, I’m focused on improving adaptability and making it even more seamless. Building this solo has been a challenge, but seeing it work on real-world pages has made it worth every late night.

The Indie Maker Journey 🛤️

This isn’t just a tech project for me — it’s a journey. From choosing the stack to debugging weird bugs at 2 a.m., being a solopreneur means wearing all the hats, from developer to marketer to customer support.

Sharing the process with the community has been incredible. If you’re on a similar path, I’d love to hear your story!
