Tenon vs SortSite 2026: API-First Testing vs Desktop Scanner

What Are Tenon and SortSite?

Tenon (tenon.io) is a commercial accessibility testing platform founded by Karl Groves, a recognized accessibility practitioner. Tenon is built API-first: send a URL or HTML payload to its REST API, and receive a structured JSON report of WCAG violations with confidence scores, CSS selectors, HTML snippets, and remediation guidance. The tool is designed to be embedded into CI/CD pipelines, automated reporting workflows, or any custom accessibility tooling.

SortSite is a desktop accessibility and web quality scanner from PowerMapper Software. It's been available since the mid-2000s and runs as a native application on Windows and Mac. Beyond WCAG scanning, SortSite checks for SEO issues, broken links, Section 508 compliance, and — uniquely — document accessibility for PDFs, Word files, and PowerPoint presentations. SortSite is a favorite among accessibility consultants, agencies, and smaller organizations that need reliable periodic auditing without cloud subscription commitments.

The core difference: Tenon is infrastructure for developers who want to automate accessibility testing at the code level. SortSite is a tool for auditors and compliance teams who need point-in-time accessibility scans across web and document content. Choosing between them comes down to whether your primary need is pipeline integration or periodic manual auditing.

CI/CD Integration: Tenon Is Built for It; SortSite Isn't

Tenon's REST API is its core strength for development teams. It accepts either a public URL (for scanning deployed environments) or a raw HTML payload (for testing server-rendered pages before they're deployed), making it flexible for different CI/CD architectures. Results come back as structured JSON — suitable for automated pass/fail gating, issue creation in Jira or GitHub, or feeding into custom compliance dashboards.

SortSite has no CI/CD integration path. It's a desktop GUI application — you open it, configure a scan, run it, and review results in the desktop interface. There's no command-line mode, no API, and no way to trigger a SortSite scan from a build system. If automated pipeline testing is a requirement, SortSite is not the right tool regardless of other factors.

Document Scanning: SortSite's Clear Differentiator

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

Tenon's API focuses exclusively on web page testing — it accepts URLs or HTML payloads and has no capability for document-format accessibility scanning. For organizations where PDF or Office document compliance is a meaningful part of their accessibility program, SortSite covers a scope that Tenon simply doesn't.

WCAG Coverage and Scan Quality

Both Tenon and SortSite cover the WCAG 2.1 AA and WCAG 2.2 AA automated rule sets for web pages. Tenon's API returns confidence scores for each violation, which is useful for filtering out low-certainty detections and prioritizing high-confidence issues. SortSite categorizes issues by severity and provides WCAG success criterion references with each finding.

A key difference in how each tool surfaces results: Tenon's JSON output is designed for programmatic consumption — developers parse the results to build workflows. SortSite's desktop interface presents a visual report with page-by-page issue listings, severity breakdowns, and WCAG references that auditors can review directly without custom tooling.

Neither tool — like all automated accessibility scanners — detects more than approximately 30–40% of real WCAG violations. Keyboard interaction testing, screen reader compatibility, focus management in JavaScript-heavy applications, and qualitative alt text evaluation all require human testing with assistive technologies.

Pricing

SortSite's pricing is transparent and modest — a straightforward annual desktop license with no per-user seat fees or page-count overages beyond the tier limits. Tenon's commercial pricing is opaque until you have a sales conversation, which can be a friction point for teams trying to compare costs. For budget planning, SortSite is easier to evaluate financially.

Who Should Use Tenon vs SortSite

Alternatives to Consider

If Tenon's appeal is CI/CD accessibility testing, axe-core (Deque, open source) is the most direct free alternative — it integrates with Playwright, Cypress, Jest, and Selenium, and is widely used in production CI/CD pipelines without any cost. WAVE API (WebAIM) is another programmatic option with different rule emphasis.

If SortSite's on-demand scanning is appealing but you also want continuous monitoring, RatedWithAI ($29/month) and Pope Tech provide automated WCAG monitoring. For larger organizations needing enterprise governance alongside scanning, Silktide and Siteimprove cover that ground with higher price tags.
