Axe DevTools vs Wappalyzer
Side-by-side comparison of features, pricing, ratings, and alternatives.
Axe DevTools is Deque Systems' accessibility testing product line, built on top of axe-core, the open-source accessibility testing engine that Deque also maintains. The free browser extension lets developers run automated, page-by-page accessibility scans directly in Chrome, while the Linter and CI integrations catch issues earlier in the development process. Paid tiers add Intelligent Guided Tests that combine automation with structured human review to catch issues automated scanners miss, component-level testing, Jira integration for tracking fixes, and an MCP server plus API for wiring accessibility checks into custom workflows. The tools integrate with common web and mobile test frameworks including Cypress, Selenium, Puppeteer, Jest, Appium, XCUITest, and Espresso.
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.
