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, Webflow, and thousands of other technologies.
The platform provides practical filtering tools that allow users to narrow results by country, TLD, industry, or specific technology combinations. This makes it useful for building targeted lead lists, researching competitors, discovering niche markets, or identifying companies using certain software stacks for outreach and partnerships.
StackScan also supports bulk data downloads, keyword-based website discovery, and structured reporting to simplify large-scale research workflows. With continuously refreshed datasets and scalable search capabilities, it enables marketers, agencies, analysts, and growth teams to access actionable web intelligence quickly and efficiently.

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.
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.
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.

There is also https://github.com/ml-explore/mlx-swift-lm which is what https://jan.ai uses. - Source: Hacker News / 30 days ago
Jan is the most polished open-source AI client available. Built with Tauri, it's lighter than Electron apps and has a genuinely clean, minimal design โ the kind where you notice the absence of clutter rather than the presence of features. It runs local models through llama.cpp and MLX, has native MCP support, an extension system, and an OpenAI-compatible API server at localhost:1337 so you can point other tools at... - Source: dev.to / 2 months ago
Jan takes a different approach, prioritizing user privacy and simplicity over advanced features with a 100% offline design that includes no telemetry and no cloud dependencies. - Source: dev.to / 9 months ago
I really like Jan, especially the organization's principles: https://jan.ai/ Main deal breaker for me when I tried it was I couldn't talk to multiple models at once, even if they were remote models on OpenRouter. If I ask a question in one chat, then switch to another chat and ask a question, it will block until the first one is done. Also Tauri apps feel pretty clunky on Linux for me. - Source: Hacker News / about 1 year ago
I believe there's a couple of similar apps like https://msty.app and https://jan.ai that do the same and allow you to plug in your own API keys. - Source: Hacker News / about 1 year ago
