SoldSignal
About

Built by one engineer and a weekly pipeline

SoldSignal exists because resale prices online are mostly asking prices, single-market, or behind a paywall. This site puts real sales from several marketplaces side by side, for free.

How it runs

Every week a pipeline runs public web-data collectors (Apify Actors written by me), cleans and matches the results, computes the statistics and rebuilds this site. The whole run costs less than a cup of coffee per month. The same collectors are public on the Apify Store, and a sample dataset is on Hugging Face and GitHub.

Who built it

I'm Malek Oweis, an AI automation engineer. I build data pipelines, scrapers, MCP servers and AI-agent workflows that run on their own.
