Questions & Answers

As answered by people managing PixellPeep and WebDiff.

What makes your product unique?

WebDiff's answer:

WebDiff checks a website on five layers in a single report: visual (desktop and mobile), SEO, links, source code and network requests. Most tools look at screenshots only. WebDiff also catches a changed title or H1, a broken link or a missing script, even when the page looks the same.

It is also a desktop app that runs entirely on your computer:

  • No code, no CI pipeline, no test scripts: just paste your URLs or import a sitemap
  • Works with localhost, staging servers, VPNs and HTTP-authenticated sites
  • No data sent to external servers

Why should a person choose your product over its competitors?

WebDiff's answer:

Tools like Percy, Applitools or Chromatic are built for development teams with automated test pipelines. WebDiff is built for people who update and maintain websites day to day and need a fast, reliable check without writing tests.

  • Ready in minutes: create a comparison, analyze Version 1, update the site, analyze Version 2
  • Unlimited sites, pages and comparisons, with no usage quotas
  • One-time payment, no subscription
  • Client-ready reports: export to PDF to show clients exactly what changed (or that nothing broke)
  • Privacy by design: everything runs locally
  • A responsive team that ships user feedback quickly, with new features released almost every month

How would you describe the primary audience of your product?

WebDiff's answer:

  • Freelance web developers who maintain many client websites
  • Web agencies that need a standard, repeatable QA process for site updates
  • WordPress managers and site administrators dealing with frequent core, theme and plugin updates

WebDiff is also used by SEO specialists (to make sure updates don't affect titles, meta tags, H1s and links), QA testers, and developers during site migrations (to compare the old and new site).

What's the story behind your product?

WebDiff's answer:

WebDiff was born at TangoDev, a small software agency in Italy, out of a problem we faced every week. You update a client's WordPress site, with core, plugins and theme, check a few pages, and everything looks fine. An hour later the client calls: some buttons have disappeared and the contact form no longer works.

Checking every page by hand with screenshots was slow and unreliable, so we built a tool for ourselves that compares the site before and after the update and shows exactly what changed. It worked so well that we released it publicly in December 2024. Since then, many releases have been shaped directly by user feedback, from the AppSumo community to Product Hunt.

Who are some of the biggest customers of your product?

WebDiff's answer:

WebDiff is used by hundreds of freelancers and web agencies around the world, many of whom joined through our AppSumo campaign. They range from solo developers maintaining a handful of client sites to agencies updating dozens of websites every month.

Which are the primary technologies used for building your product?

WebDiff's answer:

WebDiff is a cross-platform desktop app for macOS and Windows, built with modern web technologies. At its core is a proprietary analysis engine we built in-house to maximize reliability and performance: it loads each page in a real browser environment, captures visual snapshots (desktop and mobile), source code, SEO data, links and network requests, then compares the two versions and highlights every difference.

Everything runs locally on your computer: no cloud processing, no external servers.
