DevToys vs Wappalyzer
Side-by-side comparison of features, pricing, ratings, and alternatives.
DevToys is a free, open-source desktop app that bundles dozens of everyday developer utilities, such as JSON/YAML converters, Base64 and JWT decoders, hash and UUID generators, and text/JSON diff tools, into a single offline application. It automatically detects clipboard content and suggests the most relevant tool, so you rarely need to hunt through a menu. Everything runs locally rather than through third-party websites, which matters for teams handling sensitive tokens or data. DevToys is cross-platform on Windows, macOS, and Linux, offers a command-line mode for CI use, and can be extended with community-built tools distributed through NuGet.
Wappalyzer is a technology profiling tool that scans websites and reports the frameworks, CMSs, analytics tools, payment processors, and other software they run on, using a browser extension, a web-based lookup, and an API. Developers use it to research how a competitor's site is built, while sales and marketing teams use the same underlying data to build lead lists filtered by technology, geography, and traffic. The platform also offers CRM enrichment, email verification, and website alerts that notify a team when a prospect or competitor changes their tech stack. A free tier allows a limited number of lookups per month, with paid plans scaling lookup, list, and API credit volumes for larger teams.
