SiteLasso — Is your website actually working?

Check if your website is actually working. Find broken links, dead forms, and missing images — in plain English.

Right now, someone is leaving your website because something is broken. You just don't know it yet. That contact form they filled out? It submits to nowhere. That product link they clicked? 404. That image that should show your work? A blank box. Every broken element is a silent "goodbye" from a potential customer who will never tell you what went wrong. They just leave. And you keep wondering why traffic doesn't convert. SiteLasso finds what's broken in 30 seconds — not 30 hours of clicking through your own site. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 𝗪𝗛𝗔𝗧 𝗜𝗧 𝗖𝗛𝗘𝗖𝗞𝗦 → Broken links Every link on your page, verified. Internal pages, external resources, social media links — if it returns an error, you'll know which one and where it is. → Dead forms Your contact form looks fine. But does it actually work? SiteLasso checks form structure — missing submit buttons, inputs without names, nested forms that browsers silently break, and insecure HTTP submissions on HTTPS pages. It tests whether the submission endpoint actually responds. It even understands modern JavaScript frameworks, so forms handled by React, Vue, or HTMX won't trigger false alarms. If your form is broken, you'll know why — not just that something's wrong. → Missing & broken images Broken image icons make your site look abandoned. Missing alt text makes it invisible to search engines. Both get caught. → SSL & mixed content You paid for HTTPS. But one insecure image or script loaded over HTTP triggers the browser warning that makes visitors hit "Back" immediately. SiteLasso finds every mixed content resource. → Mobile issues No viewport meta tag? Unscalable content? These kill your mobile experience — and mobile is where most of your visitors are. → JavaScript errors Console errors that crash functionality. Your visitors can't see them. Neither can you — unless you open DevTools on every page. SiteLasso surfaces them automatically. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 𝗛𝗢𝗪 𝗜𝗧 𝗪𝗢𝗥𝗞𝗦 1. Open any page on your site 2. Click the SiteLasso icon 3. Get a full health report graded A through F Broken elements are highlighted directly on your page — not just listed in a sidebar, but shown exactly where they are. Single page scan takes seconds. Full site crawl covers up to 50 pages automatically — it follows your internal links, so it checks what your visitors actually navigate to. No configuration. No setup wizard. No "connect your domain." Just click and know. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 𝗧𝗛𝗘 𝗥𝗘𝗣𝗢𝗥𝗧 Every issue is written in plain English. Not HTTP status codes. Not developer jargon. Instead of "404 Not Found on /api/v2/endpoint" you get: "Broken link: About Us page links to a page that doesn't exist." Instead of "Mixed Content: loaded over HTTP": "Insecure resource on a secure page — browsers may block this." Results are graded: • A — Your site is healthy • B — Minor issues, nothing urgent • C — Several problems that need attention • D — Significant issues affecting visitor experience • F — Critical problems losing you business right now Export as PDF to hand to your developer, or plain text to paste into an email. The report does the explaining for you. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 𝗪𝗛𝗢 𝗧𝗛𝗜𝗦 𝗜𝗦 𝗙𝗢𝗥 • Freelancers who hand off sites and want to verify everything works before the client checks • Small business owners who can't afford a broken site but also can't afford a full-time developer • Marketing managers who need to prove to the dev team that yes, something IS broken • Agencies doing quick audits before client calls • Anyone who's ever said "the website looks fine to me" and been wrong ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 𝗪𝗛𝗔𝗧 𝗧𝗛𝗜𝗦 𝗜𝗦 𝗡𝗢𝗧 This is not an SEO tool. Not a performance profiler. Not a security scanner. It does one thing: tells you whether your website is actually working for the people visiting it. The stuff that costs you money when it breaks. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 𝗣𝗥𝗜𝗩𝗔𝗖𝗬 Everything runs locally in your browser. Your pages are not sent to any server. No analytics. No tracking. No account required. No data collection of any kind. The extension needs host permissions to check whether external links and form endpoints are reachable — those are simple HEAD requests to verify URLs respond, not page content scraping. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 𝗧𝗛𝗘 𝗠𝗔𝗧𝗛 𝗧𝗛𝗔𝗧 𝗠𝗔𝗧𝗧𝗘𝗥𝗦 If your site gets 1,000 visitors/month and a broken form loses you even 2% of potential leads — that's 20 people who tried to contact you and couldn't. At any reasonable customer value, a single broken element costs more per month than you'll ever spend on fixing it. The difference is: now you know it's broken. One click. Thirty seconds. Zero excuses.
