Overview
Description

Polypane is a browser built specifically for web development, showing multiple synchronized viewports side by side so developers and designers can see how a page behaves across phone, tablet, and desktop breakpoints at the same time, instead of resizing one window repeatedly. Every pane reloads together as code changes, and interactions like scrolling or clicking can be mirrored across panes. Beyond responsive previews, Polypane bundles accessibility auditing (contrast checks, focus order, ARIA warnings), SEO and social-preview inspection, and other developer tools that would otherwise require a handful of separate browser extensions. It has been independently built and bootstrapped since 2019.

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.

  • Fast way to research how a specific site is built
  • Same data serves both developers and sales/marketing teams
  • Free tier available for occasional lookups
  • Browser extension makes ad hoc lookups effortless
Cons

  • No permanent free tier, only a 14-day trial
  • Another browser window to maintain alongside your daily driver
  • Paid plans are priced for business/sales use cases, not casual developer use
  • Pro and Business tiers are expensive relative to typical developer tools
  • Detection can miss custom or heavily obfuscated tech stacks
