Tech Stack Detector SaaS

A web-based tool that analyzes websites to identify their underlying technology stack (frameworks, libraries, CMS, hosting, analytics tools). Useful for competitive analysis, sales intelligence, and developer research. Expand the browser extension into a SaaS platform with API access and reporting.

Wappalyzer has dominated this space for years and was acquired by a data broker in 2022, leaving developers frustrated with paywalled APIs and degraded free tiers — that gap is real and actively discussed in developer communities. The timing is further supported by the explosion in go-to-market tooling, where sales and RevOps teams are hungry for technographic data to fuel outbound sequences, making B2B data enrichment a credible upsell path beyond the developer audience. The $2k–$10k/mo revenue band is honest for a bootstrapped operation — API access and seat-based pricing can get you there without massive scale, though it caps out quickly unless you push into enterprise data licensing. The biggest risk is commoditization: BuiltWith, Wappalyzer, and even free browser extensions already cover 80% of use cases, so without a meaningfully fresher dataset or tighter integration into a specific workflow (say, clay.com or Apollo), you're building a slightly better version of something people already have a free workaround for.
