StackScan helps businesses find and analyze websites based on the technologies they use or the keywords they target. Instead of manually researching websites one by one, users can instantly search across 100M+ domains and identify sites using platforms like Shopify, WordPress, WooCommerce,...
Most status pages collapse the whole world into one green dot. If you're up in Virginia but down in Frankfurt, that dot is lying to your customers. RealUptime checks from four regions (US East, US West, Europe, Asia Pacific) and shows every region's reading by default, so a partial outage can...

As answered by people managing StackScan and RealUptime.io.
StackScan's answer
StackScan focuses on practical usability, broader stack coverage, advanced filtering, and scalable exports without unnecessary complexity. Users can quickly generate highly targeted datasets using filters like country, TLD, industry, and technology combinations, making research and lead generation faster and more precise.
RealUptime.io's answer:
Two reasons. First, honesty by default: per-region status readings your customers can trust, instead of a single dot that averages problems away. Second, predictable cost: incumbents charge per status-page subscriber or per check, which punishes you for growing. RealUptime is a flat monthly price, the free tier is permanent, and one platform covers status pages, uptime monitoring, and error tracking so you are not stitching three vendors together.
StackScan's answer
StackScan combines technology stack discovery and keyword-intent research in a single platform, allowing users to find websites not only by the tools they use but also by what they are targeting online. With coverage across 50,000+ technologies and 100M+ domains, it provides scalable, filterable, and export-ready web intelligence.
RealUptime.io's answer:
Every check runs from four regions and every region's reading is shown by default, on the public status page, not buried in a dashboard. Most tools collapse the world into one green dot, which means a regional outage can hide behind a healthy average. RealUptime treats "up in Virginia, down in Frankfurt" as information your customers deserve to see. That, and flat pricing: no per-subscriber fees, no per-check metering.
StackScan's answer
StackScan is built for marketers, growth teams, agencies, sales teams, analysts, SaaS companies, and researchers who need structured web intelligence for prospecting, competitor analysis, market research, or technology adoption tracking.
RealUptime.io's answer:
Developers, small software companies, indie founders, and agencies who need to tell their own customers the truth about an outage. Teams big enough to need a status page and monitoring, but not big enough to want enterprise observability pricing.
StackScan's answer
StackScan was created to simplify the process of finding reliable website and technology data at scale. Existing solutions often felt limited, expensive, or difficult to use for targeted workflows, so StackScan was built as a practical and scalable platform that combines technology detection, keyword discovery, and bulk data access into one system.
RealUptime.io's answer:
I spent 8 years managing a T-Mobile retail store before building this. Retail teaches you that customers forgive problems but never forgive being lied to. When I looked at status page tools, the standard design was a single green dot that stays green while a whole region is down. I built RealUptime as the tool I would trust as a customer: every region shown, flat pricing, and a free outage tracker measured by our own probes instead of trusting vendors' own status pages.
StackScan's answer
StackScan is built using modern web technologies, large-scale crawling systems, distributed data processing, and technology fingerprinting engines designed to analyze and structure massive amounts of web data efficiently.
RealUptime.io's answer:
Next.js and TypeScript, PostgreSQL, and a probe fleet deployed across four regions on Fly.io.
StackScan's answer
StackScan is used by agencies, SaaS businesses, growth teams, researchers, and data-driven organizations for lead generation, market intelligence, and competitive analysis across multiple industries.
