Find and fix the problems hiding in your app.
AppScan checks websites and apps for bugs, slow pages, security gaps, accessibility barriers and SEO problems. Start with the free automated scan below. Full audits are performed by Joel Owhe, founder of Yonda Solutions, with vetted specialist partners on larger engagements.
Scan your site in seconds, free
Enter a URL for an instant preliminary check across security, SEO, accessibility, best practices and performance. No signup required.
We run a safe, read-only check of the public page you enter, plus Google Lighthouse. Code, API and hands-on testing are part of a full audit.
Preliminary health score
This is a quick automated surface scan. A full audit adds hands-on review, code and security testing, cross-browser and mobile checks, and fixes if you want them (quoted separately).
Not sure about a link? Check it before you click.
Paste a suspicious link from an email, a text or a message and see what it really points at. Your browser never opens the link, so checking it is safe.
Your browser never opens the link. The structure is analysed on your device; our server then looks up only the domain’s registration date and Google Safe Browsing status (and, for short links, where the redirect points). Checks are not saved.
The rule that beats every phishing page: never sign in to an account from a link someone sent you. If a message says there's an invitation, parcel, document, or security alert waiting, open the site yourself in a new tab or use its app. If it's genuine, it will be there.
Worried you already clicked something?
Our free security guide explains exactly how to secure a compromised email account — and why changing your password first doesn't work. Free to share with anyone who needs it.
We send the guide once. No mailing list, no follow-up sequence.
Got a suspicious email? Paste it in.
Copy the whole email and paste it below. We check every link it contains, compare what each link says with where it actually goes, and flag the pressure tactics phishing relies on.
Whatever this says, the safe move is the same: never sign in from a link in an email. If it claims there's an invitation, parcel, document, or security alert waiting, open the site yourself in a new tab or use its app. If it's genuine, it will be there.
Already replied or signed in somewhere?
Our free security guide walks through securing a compromised email account in the order that actually works — sessions first, password last. Free to forward to anyone who was caught by the same message.

Everything we check
A full audit looks at the whole application, from the code your users never see to the experience they have every day.
Functional bugs & regressions
Broken flows, edge cases, and features that quietly stopped working after a release.
Performance & load speed
Slow pages, heavy bundles, memory leaks and bottlenecks, measured against realistic budgets.
Security & vulnerabilities
Injection, auth flaws, exposed secrets and vulnerable dependencies, mapped to OWASP risk categories.
Accessibility (WCAG)
Contrast, keyboard navigation, ARIA and screen-reader support, checked against WCAG 2.2.
Code quality & tech debt
Complexity hotspots, dead code and anti-patterns that make changes slow and risky.
UX & usability
Confusing flows, friction points and drop-offs that cost you conversions.
SEO & metadata
Crawlability, structured data, meta tags and Core Web Vitals that affect search ranking.
Cross-browser & mobile
Rendering and behaviour checked across the browsers, devices and screen sizes your users have.
APIs & integrations
Flaky endpoints, error handling, rate limits and third-party integrations.
