Testing Tools
Free website checkers typically test SEO, page speed, and meta tags — things that matter to search engines. They don't test whether your site works for users: whether forms submit, whether checkout completes, whether login succeeds. This guide covers what a complete free website check looks like and what
Testing Tools
Most "check my website" guides point you at SEO scores, Lighthouse audits, and uptime monitors. These tools are useful but they cannot tell you whether your site actually works for users. This guide is the practical checklist for checking what matters: can users complete the tasks your site
Testing Tools
Most website security testing tools check for malware, SSL certificates, and known vulnerabilities. They do not check whether your access controls actually work — whether a logged-out user can reach an admin page, whether a standard user can access another user's data, or whether your role permissions are enforced
Testing Tools
A website that is "mobile-friendly" passes a responsive design check — the layout adapts to smaller screens. That is not the same as a website that works on mobile. Mobile functional testing verifies that users on phones and tablets can complete the same flows as desktop users: checkout, login,
Testing Tools
Speed testing measures how quickly pages load. Functional testing measures whether the loaded page actually works. These are independent — a fast site can have broken features, and a slow site can have fully functional features. Both matter, but they matter for different reasons and require different tools. This guide covers
Testing Tools

Testing Tools
Broken link checkers find links that return 4xx or 5xx HTTP responses. They do not check whether the links that return 200 actually go to the right place. A navigation link that sends users to a competitor's site returns 200 OK. A checkout button that redirects to the
Testing Tools
Website audit tools typically evaluate SEO health, performance metrics, and technical crawlability. None of them verify whether your website's actual features work. A functional audit checks what SEO audits cannot: whether forms submit, flows complete, checkout processes, and users can accomplish their goals. This guide covers both types
Testing Tools
Most website scanners check for malware, SEO issues, or broken links. None of them check whether your checkout button works. Functional website scanning — verifying that user flows complete successfully — is the category of scanning that actually affects revenue. This guide covers how to do it. Key Takeaways Scanners that check
Testing Tools
Testing a website does not require coding skills. What it requires is a systematic approach to verifying that every important user action actually works — forms submit, logins complete, checkouts process, navigation leads where it should. This guide covers how to do that manually, and how to automate it so you

Canary is an AI QA tool for engineering teams that want to connect their source code and generate tests from PR diffs. If you need a Canary alternative — because you can't share source code access, need non-engineers to write tests, want 24/7 monitoring, or need predictable flat

Mabl is a capable AI test automation platform, but its custom enterprise pricing, slow performance at scale (users report 40-minute runs that used to finish in 12), and the friction of a sales process make it a poor fit for many teams. The best mabl alternatives in 2026 depend on
