Our verdict on StackDetect
StackDetect is a technographics platform for sales prospecting, agency research, competitor monitoring, ecommerce targeting, market research, and data enrichment teams. It identifies technologies used by websites, organizes technology and company data, and supports domain lookups, searchable research, and technology-filtered lead-list building. The product runs on the web and includes a Chrome extension for browser-based detection, making it suited to teams that need technology intelligence during prospecting and website research.
StackDetect uses a freemium pricing model. The Start free plan includes 50 technology lookups per month and free sample lead lists, giving individual researchers and smaller teams a way to evaluate the core workflow. The published plan highlights also cover filtering by industry, location, traffic, and company size, along with CSV lead-list exports. Email verification and CRM data enrichment extend the value of the prospecting workflow beyond basic technology identification.
Its strongest differentiator is the combination of detection and prospecting infrastructure. Users can look up technologies and domains, create filtered lists, monitor websites with alerts, review technology change history, and connect workflows through REST API access. That breadth makes StackDetect a practical fit for teams that want technographic signals tied to lead generation and enrichment. It is less suitable for buyers seeking a general sales platform or a broader export workflow than the CSV-based process described here. Choose it for focused technology-based research and prospecting, especially when a free starting tier matters.
