Can SortSite scan PDFs and Office documents?

Yes — SortSite's ability to scan PDFs, Word documents, and PowerPoint files for accessibility issues is one of its distinctive features. This is valuable for organizations that publish document-heavy content (government agencies, legal firms, educational institutions). Silktide focuses primarily on web page accessibility and content quality, with less emphasis on document-format scanning. If document accessibility is a significant part of your compliance program, SortSite's document scanning capability is a meaningful differentiator.

Silktide vs SortSite 2026: Enterprise Governance vs Desktop Scanner

Q: Is Silktide better than SortSite for accessibility testing?

Silktide and SortSite are fundamentally different tools targeting different buyers. Silktide is a cloud-based enterprise web governance platform priced at $500–$10,000+ per month, designed for large organizations managing hundreds or thousands of pages with ongoing compliance monitoring, content quality scoring, and team workflow features. SortSite is a desktop application priced at $299–$995 per year that performs on-demand WCAG, Section 508, and SEO scans. If you're a large enterprise or government body needing continuous monitoring with team management features, Silktide is more appropriate. If you need a straightforward, affordable desktop scanner for periodic audits, SortSite is the better fit.

Q: How much does Silktide cost compared to SortSite?

There is a large pricing gap between these tools. Silktide is estimated at $500–$10,000+ per month depending on the number of pages monitored and features required — it's an enterprise platform with enterprise pricing. SortSite is $299/year for the Standard tier (5 simultaneous pages) up to $995/year for the Professional tier (100 pages). For budget-conscious teams, SortSite is dramatically more affordable. Silktide's premium pricing reflects its continuous cloud monitoring, team collaboration features, and broader web governance capabilities beyond accessibility alone.

Q: Does SortSite work on Mac?

Yes, SortSite is available for both Windows and Mac. The desktop application runs natively on macOS as well as Windows, which gives it a broader reach than some legacy accessibility tools that are Windows-only. Silktide, being a cloud SaaS platform, is browser-accessible from any operating system and doesn't require a desktop install.

What Are Silktide and SortSite?

Silktide is a UK-based web governance and accessibility monitoring platform that has evolved from its origins in accessibility scanning into a broader content quality, SEO, and compliance management suite. It's widely used by UK government bodies, universities, and large enterprises that need centralized visibility across hundreds or thousands of web pages. Silktide provides continuous monitoring, team task management, content scoring, and regulatory compliance tracking — making it much more than a simple WCAG scanner.

SortSite is a desktop accessibility and web quality scanner developed by PowerMapper Software. It runs on Windows and Mac, performs WCAG 2.1/2.2, Section 508, and SEO checks on websites, and notably extends its scanning to documents — including PDFs, Word files, and PowerPoint presentations. SortSite has been available since the mid-2000s and remains a go-to tool for accessibility consultants, smaller agencies, and organizations that need affordable, periodic auditing without a cloud subscription commitment.

The comparison between Silktide and SortSite is really a comparison between two accessibility program philosophies: continuous enterprise governance versus affordable on-demand scanning. Understanding which philosophy your organization needs is more important than any feature-by-feature analysis.

Pricing: A Wide Gap

Silktide Pricing

Starting price: ~$500+/month for small deployments
Mid-tier: $2,000–$5,000/month for larger page counts
Enterprise: $10,000+/month for enterprise-wide deployments
Pricing model: Number of pages monitored + feature tier
Free trial: Available — contact sales

SortSite Pricing

Standard: $299/year (up to 5 simultaneous pages)
Professional: $499/year (up to 50 pages, more rules)
Professional+: $995/year (up to 100 pages)
Pricing model: Annual desktop license per machine
Free trial: 30-day trial available for download

The pricing gap is stark. A mid-tier Silktide deployment costs roughly 24–60x more annually than a SortSite Professional license. For many organizations, this alone drives the decision: enterprises with budget and compliance mandates choose Silktide; cost-conscious teams and solo practitioners choose SortSite.

It's worth noting that Silktide's pricing reflects its scope — continuous monitoring, team workflow, content management integrations, and web governance beyond accessibility. You're not just paying for WCAG scanning; you're paying for a compliance management platform. SortSite delivers focused accessibility scanning at a fraction of the cost but provides none of the continuous monitoring, team management, or governance workflow features that Silktide includes.

Feature Comparison

Where Silktide Excels

Continuous monitoring: Silktide crawls your site on a schedule and surfaces new accessibility regressions as they appear — no manual scans required.
Team workflow: Issues can be assigned to team members, tracked to resolution, and rolled up into compliance dashboards — critical for enterprise programs.
Content quality scoring: Beyond WCAG, Silktide scores readability, broken links, SEO signals, and overall content health — making it a holistic web governance tool.
Multi-site management: Organizations managing multiple websites or sub-sites can view consolidated compliance scores across their entire web estate.
UK government adoption: Silktide has significant penetration in UK public sector, which has mandatory PSBAR accessibility compliance requirements.

Where SortSite Excels

Document scanning: SortSite scans PDFs, Word, and PowerPoint files for accessibility issues — a differentiator for document-heavy organizations.
Offline / air-gapped scanning: As a desktop tool, SortSite can scan local servers, staging environments, and intranet sites that cloud tools can't reach.
Low cost of entry: At $299/year, SortSite is accessible to small nonprofits, independent consultants, and small agencies without enterprise budgets.
No subscription lock-in: Annual desktop licensing is straightforward with no per-user seat fees or page-count overages.
Section 508 / PDF coverage: Strong coverage for government and federal contractor compliance requirements including Section 508 and PDF/UA.

WCAG Coverage and Scanning Depth

Both Silktide and SortSite cover WCAG 2.1 AA and WCAG 2.2 AA automated rules. Neither claims to be a manual testing replacement — and neither should be treated as one. The industry consensus is that automated accessibility testing catches 30–40% of real WCAG violations; the remainder require human testing with assistive technologies.

Silktide's scanning engine is cloud-based and continuously re-crawls your site, meaning it catches regressions as content is published without any manual trigger. This is a genuine advantage for large editorial teams where accessibility regressions can be introduced by content editors who aren't accessibility-trained.

SortSite performs full-site crawls on demand. For a typical site under 500 pages, a SortSite scan runs in minutes. The results are presented in a desktop application with clickable issue listings, detailed WCAG references, and page-by-page breakdowns. The scan depth is comparable to most cloud tools for static and server-rendered sites — but it cannot monitor for regressions between scans.

Key Limitation: On-Demand vs Continuous

SortSite's biggest practical gap versus Silktide is monitoring frequency. If your organization publishes new content regularly, SortSite only shows you the state of your site at the moment you scan. Accessibility regressions introduced between scans go undetected until the next manual audit. Silktide's continuous monitoring closes this gap — at a significantly higher cost.

Document Scanning: SortSite's Unique Advantage

One of SortSite's genuine differentiators is its ability to scan PDFs, Word documents, and PowerPoint presentations for accessibility issues alongside web pages. Government agencies, legal organizations, healthcare providers, and educational institutions that publish large volumes of documents alongside their web content benefit significantly from this capability.

SortSite checks PDFs against PDF/UA standards and WCAG requirements — tagging, reading order, alt text for images, form field labels, and document language. For a government agency managing hundreds of published PDFs alongside its web content, this document-level coverage can be the deciding factor in choosing SortSite over web-only tools.

Silktide focuses predominantly on web page accessibility and content quality. Its document accessibility coverage is more limited, and organizations with heavy document publishing requirements would likely need a supplementary tool regardless of which platform they choose.

Frequently Asked Questions

Is Silktide better than SortSite for accessibility testing?

Silktide is a more powerful tool for enterprise continuous monitoring, team workflow, and multi-site governance — but it costs dramatically more ($500–$10,000+/month vs SortSite's $299–$995/year). SortSite is better for smaller organizations, consultants doing periodic audits, and anyone who needs document scanning (PDFs, Word, PowerPoint). The right choice depends on your organization's size, budget, and whether you need continuous monitoring or periodic scanning.

How much does Silktide cost compared to SortSite?

Silktide is estimated at $500–$10,000+/month depending on page count and features. SortSite ranges from $299 to $995 per year as a desktop license. At the low end, Silktide can cost 20x more annually than SortSite; at the high end, the gap is even larger. Silktide's price reflects its continuous monitoring, team management, and broader web governance scope. SortSite's lower price reflects its focused, on-demand scanning use case.

Does SortSite work on Mac?

Yes. SortSite is available for both Windows and Mac as a native desktop application. This makes it accessible to teams on either platform without compatibility issues. Silktide is a cloud SaaS platform accessible from any browser, with no desktop installation required.

Can SortSite scan PDF and Word documents for accessibility?

Yes — document scanning is one of SortSite's key differentiators. It scans PDFs against PDF/UA and WCAG standards, and checks Word and PowerPoint files for accessibility issues. This is especially valuable for government agencies, legal firms, and educational institutions that publish significant volumes of documents. Silktide focuses primarily on web pages and has more limited document accessibility coverage.

Which tool is better for UK government PSBAR compliance?

Silktide has significant adoption among UK public sector organizations and is built with PSBAR (Public Sector Bodies Accessibility Regulations) compliance in mind. It supports the monitoring, reporting, and remediation workflow that large public sector web estates require. SortSite can perform WCAG scans relevant to PSBAR but lacks the continuous monitoring and team governance features that large government web teams typically need.
