Five scan modules. One system-wide analysis.

  • Accessibility

    Scan your site for WCAG 2.2 accessibility issues. Find problems that affect how real people use your site—like missing labels, poor contrast, and unclear structure—along with clear guidance on how to fix them.

  • SEO & AI Optimization

    Review your site's structure, metadata, broken links, and content clarity to improve how it's understood by search engines and AI tools like ChatGPT, Claude, and Perplexity.

  • Performance

    Measure Core Web Vitals and real-world speed using Lighthouse, with clear page-level results and improvement tips.

  • Spell Check

    Find typos and repeated content errors across your site, with context and support for custom dictionaries.

  • HTML Validation

    Check your site against HTML standards. This module is optional, and most issues are already covered in Accessibility and SEO—but it can be useful for deeper technical review.

Find.
Learn.
Fix.

BetaSweep helps you understand every issue through clear explanations, practical guidance, and technical detail when needed, giving you the knowledge to fix today’s issues and prevent tomorrow’s. Finding an issue is only the first step—understanding why it matters and knowing how to fix it is what creates meaningful improvement. No vanity scores. Just actionable results. Performance gets a score because speed exists on a spectrum. Everything else is simple: pass, recommended, or fix it—because a website that’s “98% accessible” can still create barriers for real people.

Why You’ll Love BetaSweep

  • Five Tools in One

    Run one scan that checks accessibility, SEO, AI readability, performance, spelling, and HTML issues in a single report. No need to piece together results from different tools.

  • Full-Site Scanning

    Scan your entire website in both desktop and mobile views in a single pass. Find issues across all pages and templates so you can see how problems repeat and connect across your site.

  • Scan when you want. Pay when it matters.

    Most websites don’t change much from week to week, and many issues only need to be fixed once. BetaSweep lets you scan any website for free and choose the reporting option that fits your needs—from a single detailed report to ongoing access when it makes sense.

  • SEO & AI Findability in One

    See how your site is understood by search engines and AI tools like ChatGPT, Claude, and Perplexity. Improve structure and clarity so more people can find your site.

  • Trusted Scanning Engines

    Powered by trusted tools like Lighthouse (performance), axe-core (accessibility), and HTML standards validation—so results are accurate, consistent, and grounded in widely used web standards.

  • Rescan and Track Progress

    Run scans anytime and compare results over time. See what improved, what changed, and what still needs attention.

  • Built for One or a Whole Team

    Share reports with clients, coworkers, or contractors. Export as PDF for presentations, Excel for tracking, or CSV for tools like Jira or Linear.

  • Runs on Your Computer

    All scans run locally for speed and privacy, keeping your website data on your machine instead of external servers. Available for macOS and Windows.

  • Easy and Powerful

    A WCAG 2.2 and Core Web Vitals scanner clear enough for business owners, with the technical depth developers and accessibility pros need.

Detailed.
Shareable.

  • PDFClean, formatted reports ready to share with clients or teammates
  • ExcelStructured data with separate sheets for each scan module
  • CSVSimple data you can import into tools like Jira, Trello, or Linear

Estimate Your Scan Time

Scan times depend on the website, selected scan modules, number of pages, and your computer’s performance. BetaSweep runs in the background, so you can keep working while your scan completes.

Need a Faster Scan?

By choosing the Select Pages option in BetaSweep’s scan settings, you can reduce scan times by focusing on key page types or templates instead of your entire site. This is especially useful for larger sites.

BetaSweep takes a different approach to website auditing. Instead of treating accessibility, SEO & AI, performance, HTML validation, and website structure as separate concerns, BetaSweep analyzes your website as a complete system. Because these areas influence one another, viewing them together provides a more complete picture of your website’s overall health.

BetaSweep is also designed to make website audits easier to understand. Every issue includes clear explanations, practical recommendations, and educational resources so you can understand what the issue means, why it matters, and how to fix it—whether you’re a developer, marketer, or business owner.

Finally, BetaSweep puts you in control. Scan any website for free, choose exactly what you want to scan, and only pay when you need the detailed results. Most websites don’t change dramatically from week to week, so there’s little value in paying for the same report over and over. With BetaSweep, you decide when it’s time to scan again and when it’s worth unlocking a report.

BetaSweep was developed in collaboration with the team behind Flavor Plate, a platform that serves restaurant websites across the United States and internationally. Through years of designing, building, and maintaining websites, we saw the same issues appear again and again—from accessibility barriers and SEO problems to performance bottlenecks and structural issues.

While there were already plenty of auditing tools available, many were either too technical, too expensive, or built around recurring subscriptions that didn’t always match how websites are actually maintained. We wanted to create a tool that was easier to understand, more practical to use, and accessible to organizations of every size.

Today, BetaSweep can scan websites with up to 5,000 pages while remaining especially focused on helping small businesses improve accessibility, visibility, usability, and overall website quality. Feedback is always welcome at support@betasweep.com.

Anyone responsible for keeping a website healthy. Business owners running their own sites who want to know what's working and what isn't. Website managers and content teams handling day-to-day quality. Designers checking that their work meets accessibility standards. Developers wanting a baseline before launch or after a deploy. The interface is built to be readable without a technical background, but the data underneath is detailed enough for engineers and accessibility specialists to act on directly.

No. The interface is designed for non-technical users to understand what's wrong and how to prioritize fixes. Each issue includes a plain-language explanation of why it matters and, in most cases, how to fix it. Developers and specialists still get the technical details—code snippets, ancestry trees, exact rule references—without those getting in the way for everyone else.

Every scan includes a free overview — a high-level look at how your site performed in each module you ran, with issue counts by severity. It tells you whether your site is healthy and where problems are concentrated. If everything looks good, you're done. If you want the details, unlock the full report.

A detailed report shows every issue found: the affected pages, the exact code involved, severity levels, and fix recommendations written in plain language. You can filter by severity or page, add your own notes, and export the whole thing as PDF or Excel.

Scans are always free. Every scan includes a free overview of your website’s health. You only pay if you want to unlock the detailed report.

BetaSweep offers three ways to unlock detailed reports:

  • Pay Per Report starts at $5 and includes your first page. Each additional page is $0.50, up to a maximum of $39 per report. This means you only pay for the pages you scan, making it a great option for smaller websites and one-time audits.
  • Single Site Unlimited is $39/month and includes unlimited detailed reports for one website.
  • Unlimited is $59/month and includes unlimited detailed reports for unlimited websites.

Current pricing is at betasweep.com/pricing. Payments are processed securely through Stripe.

BetaSweep runs locally on your computer for speed, reliability, and privacy. Scanning large websites requires a lot of processing, and running locally avoids delays and server queues. Your website data stays on your machine instead of being sent to external servers.

Single-page scans only show part of the picture. Most websites have many pages built from shared templates, and issues often repeat across them. BetaSweep scans your entire site so you can see patterns, not just isolated problems. You can also narrow the scan to specific pages or sections when needed.

BetaSweep can scan sites with up to 5,000 pages in a single scan. For most modules—Accessibility, SEO & AI, Spell Check, and HTML Validation—scan time scales with page count, and a typical 50-page site finishes in a few minutes. Performance is the most time-intensive module because it runs a full Lighthouse audit on each page. Because of this, you don't need to run Performance on every page for large sites. Pages built from the same template tend to perform similarly, so you can instead scan a representative set of URLs to get accurate overall insights.

Yes. You can browse, write, and work in other apps while BetaSweep scans. One note: the Performance module measures real loading speed on your machine, so heavy tasks — video calls, large exports, gaming — can affect those scores. For the most accurate performance numbers, let the scan run without heavy work in the background.

Yes. Large scans can take an hour or more, and overnight is a great time to run them. BetaSweep keeps your computer from sleeping while a scan runs, so you can step away — or close the lid, on supported machines — and come back to finished results.

BetaSweep runs on macOS and Windows. Both versions are signed and notarized for security, and both update automatically when a new version is released.

Yes, for most things. You need a connection to scan sites on the web, sign in, and unlock reports. If you go offline, BetaSweep lets you know and pauses actions that need connectivity until you're back online.

Yes. Scans run on your computer, and your scan data stays there, encrypted at rest. Nothing about your website is sent to our servers during a scan. The only data we collect is what's needed to run your account, process payments, and reply to feedback you send us.

We're fully aware of the irony here. The honest answer: not yet. It's really close—but like we say, even 90% compliant isn't compliant. We're holding ourselves to the same bar we hold your sites to, and we'll get there.

No. BetaSweep's scanning engine uses industry-standard libraries like axe-core and Lighthouse as a foundation, but the whole-site scanning, cross-page analysis, result aggregation, rule enrichment, and reporting are built specifically for BetaSweep. Every page is scanned in a single automated pass, and results are consolidated across your entire site so you can see patterns and prioritize what matters most.

Scan results are deterministic—the same page will produce the same results every time. There's no AI generating or interpreting your results.

The "AI" in the SEO & AI module refers to what it checks for, not how it works. It evaluates whether your site is structured in a way that AI tools like ChatGPT, Claude, and Google's AI Overviews can understand and accurately represent—things like structured data, meta tags, and llms.txt.

Yes. Cancel anytime from your dashboard — no phone calls, no hoops. You keep access through the end of your current billing period, and you won't be charged again.

See how fast your site really feels. The Performance module uses Google's Lighthouse engine to measure Core Web Vitals and other speed metrics on every page, on both desktop and mobile. You'll get clear scores and know exactly where things are slowing you down.

  • Powered by Lighthouse—Google's open-source engine behind PageSpeed Insights and Chrome DevTools
  • Measures all six Core Web Vitals:
    • LCP (Largest Contentful Paint)—how long the biggest visible element takes to load
    • FCP (First Contentful Paint)—how long until the page stops feeling blank
    • TTI (Time to Interactive)—how long until buttons, links, and forms actually work
    • TBT (Total Blocking Time)—how long the page looks loaded but feels frozen
    • CLS (Cumulative Layout Shift)—how much the page jumps around as it loads
    • Speed Index—how quickly the visible area fills in
  • Tests desktop and mobile separately
  • Network throttling: no throttle, simulated 4G, or simulated slow 3G
  • Scores each page Poor, Needs Work, or Good on a 0–100 scale
  • Runs each page in an isolated process, so one slow page doesn't drag down the rest
  • Works on password-protected and firewall-protected sites

Catch typos before your visitors do. The Spell Check module scans every page for misspelled words across body text, headings, links, alt text, and meta tags. Add your own brand names and technical terms to skip—so you only see what actually needs a second look.

  • US English dictionary with a modern supplementary word list (~172 extra terms)
  • Scans visible text, headings, link text, alt text, and meta content
  • Results are called "flagged words"—never assumed to be errors
  • Custom exclude list for brand names, technical terms, and intentional spellings
  • All results use moderate severity—no false alarms ranked as critical

Keep your code clean. The HTML Validation module checks your pages for broken markup—unclosed tags, invalid nesting, deprecated elements, and other issues that can cause rendering bugs or break assistive tech. Most of what it catches is already covered by the Accessibility and SEO & AI modules, so it's off by default. One toggle and it's on.

  • ~30 validation rules across 4 severity levels
  • Catches unclosed tags, invalid nesting, deprecated elements, and malformed attributes
  • Detects missing doctypes, duplicate IDs, empty elements, and void element misuse
  • ARIA and accessibility-related HTML issues are routed to the Accessibility module for better accuracy
  • 30 rules with extra guidance explaining what's wrong and how to fix it
