Internet Intelligence

Optimizers.IO can detect more than 1600 technologies that websites and web platforms are built with.

Founded in 2018, Optimizers.IO curated an extensive list of patterns used by many technologies.
Using those patterns we try to detect the technologies and solutions used to build an online web presence.

Our distributed crawlers are running for years to classify websites in specific categories, collect useful data for business owners to serve the following purposes :

  • Market and Competition research
  • Lead generation
  • Detecting Security threats
  • SEO analysis
  • Enhancing performance


We are maintaining an intelligence database of 47 millions websites and platforms updated on daily basis.

Currently, only our technologies scanner is publicly available, in the next few weeks we will release the following tools :

  • SEO scanner
  • SSL checker with recommendations
  • High authority domains to be expired soon
  • Agent-less Monitoring platform

How our scans work

We process each day more than 100,000 scans from a distributed network of workers.

We built over the last years a database of more than 260 millions domain name sharded and categorized by TLD, country, and some by business type .

Each day we queue more than a 100,000 domains for scans over many factors. Our workers are backed by Amazon lambda functions and the different regions to perform the appropriate scan by loading the whole domain page as a real visitor, then studying the DOM elements, DNS, Finding any possible vulnerability and without linking it to the domain name for safety reasons.

We love Open source, and Optimizers.IO stack was never gonna be possible without the following tools :

  • OpenResty
  • Wappalyzer
  • Puppeteer
  • Chromium
  • Google's Lighthouse
