How do Silktide and Tenon compare on pricing?

Silktide is priced at approximately $500–$10,000+ per month depending on page count and features, targeting enterprise buyers. Tenon offers a limited free tier for evaluation, with commercial plans for production use — exact pricing is contact-sales but is generally more accessible than Silktide for smaller teams. Both tools require budgeted spend for serious use, but they're priced for very different buyer segments: Silktide for enterprise governance programs, Tenon for developer teams needing an accessibility testing API.

Silktide vs Tenon 2026: Web Governance vs API-First Testing

Q: Is Silktide better than Tenon for accessibility testing?

Silktide and Tenon serve fundamentally different audiences. Silktide is a cloud-based enterprise web governance platform designed for large organizations — government, higher education, enterprise — that need continuous monitoring, team workflow, and compliance dashboards across their web estate. Tenon is an API-first accessibility testing platform built for developers who need programmatic WCAG testing integrated into CI/CD pipelines. If you're an enterprise with a non-technical compliance team managing a large site, Silktide is the better fit. If you're an engineering team that wants to catch accessibility regressions in your build pipeline, Tenon is more appropriate.

Q: Does Silktide have an API like Tenon?

Silktide provides some API access for enterprise customers to export data and integrate with other systems, but its core product is a SaaS governance platform — not a developer-facing testing API. Tenon is built API-first: the core product is a REST API that accepts URLs or HTML payloads and returns structured JSON with WCAG violation data. For developers who want to embed accessibility testing directly into their code, CI pipeline, or custom tooling, Tenon's API-first design is a clearer fit than Silktide's platform-centric model.

Q: Can I use Silktide and Tenon together?

Yes — they don't overlap in the problems they solve. Tenon in a CI/CD pipeline catches code-level accessibility regressions before deployment. Silktide provides continuous monitoring of the production site, content quality tracking, and team remediation workflow after deployment. Organizations that have both a developer pipeline and a large editorial content team sometimes run complementary tools addressing both layers. That said, the combined cost of enterprise Silktide plus Tenon's commercial API would be significant — evaluate whether you actually need both layers or whether one covers enough of your requirements.

What Are Silktide and Tenon?

Silktide is a UK-based web governance platform that has expanded from accessibility scanning into a comprehensive web quality management suite. It provides continuous monitoring of accessibility compliance, content quality, readability, SEO signals, and broken links across large web estates. Its primary buyers are government bodies (especially UK public sector), universities, and large enterprises that need centralized oversight, team workflow for remediation, and compliance dashboards for leadership reporting.

Tenon (tenon.io) is a commercial accessibility testing platform built by Karl Groves, a well-known accessibility researcher and practitioner. Tenon's philosophy is that accessibility testing should be programmatic, measurable, and integrated into the development workflow — not a periodic manual checklist. The core product is a REST API: send a URL or HTML payload, receive a JSON report of WCAG violations with confidence scores, CSS selectors, and remediation guidance. Tenon integrates into any CI/CD pipeline or custom tooling.

The comparison between these tools is really a comparison between two parts of an accessibility program: Silktide addresses the governance and monitoring layer for non-technical teams; Tenon addresses the development pipeline layer for engineering teams. In large organizations, these layers are complementary rather than competing.

Use Cases: Where Each Tool Belongs

Silktide Use Cases

UK public sector compliance: Silktide is purpose-built for PSBAR (Public Sector Bodies Accessibility Regulations) monitoring and reporting requirements.
Large editorial sites: Organizations where non-technical content editors publish pages benefit from Silktide's continuous monitoring that catches regressions without developer involvement.
Multi-site portfolio management: Enterprise organizations managing multiple brand sites or sub-sites can get consolidated accessibility scores across their web estate.
Executive compliance reporting: Silktide's dashboards present accessibility scores in terms that non-technical stakeholders and leadership can interpret for governance and legal purposes.
Content quality + accessibility combined: Silktide's broader scope (readability, broken links, SEO signals) means it serves as a single platform for overall web quality governance.

Tenon Use Cases

CI/CD pipeline gating: Tenon's REST API can be called from any build system (GitHub Actions, Jenkins, CircleCI) to fail builds when accessibility violations exceed a defined threshold.
Programmatic bulk URL testing: Submit hundreds of URLs programmatically, receive structured JSON, and automate ticket creation or reporting workflows.
Server-side rendering testing: Tenon can accept raw HTML payloads, allowing teams to test server-rendered pages before deployment without requiring a live URL.
Confidence-scored violation filtering: Tenon's confidence scores enable teams to filter out low-certainty issues and focus remediation on high-confidence WCAG violations first.
Custom accessibility tooling: Engineering teams building internal accessibility dashboards, reporting tools, or automated audit workflows use Tenon as a backend testing engine.

CI/CD Integration: Tenon Wins Clearly

For engineering teams that want accessibility regression testing in their build pipeline, Tenon is the more appropriate tool. Tenon's REST API is language-agnostic — it can be called from Python, Node.js, Ruby, Go, or any other language, or directly via curl from a shell script in any CI system.

Tenon CI/CD Integration Pattern

POST to Tenon API with URL or HTML payload + API key from build environment secrets

Receive JSON: array of issues with WCAG criterion, severity, certainty score, CSS selector, HTML snippet

Filter by certainty ≥ 60 (or chosen threshold) to reduce false positives

Fail CI build if violations exceed threshold, or create Jira/GitHub Issues from the structured output

Silktide does not offer this kind of developer-facing API integration. Its scanning is platform-driven — Silktide crawls your site on its own schedule, and results surface in the Silktide dashboard. There's no mechanism to trigger a Silktide scan from a CI/CD job and have it gate a deployment. For development teams, this is a meaningful gap.

Governance and Team Workflow: Silktide Wins Clearly

Silktide's team workflow and governance features have no equivalent in Tenon. Organizations managing web teams where multiple people own different sections of a website benefit from Silktide's ability to assign accessibility issues to specific team members, track remediation progress, set compliance targets, and report on progress over time.

For a university managing a web estate where each department controls its own section, or a government body with multiple agency websites, Silktide's centralized visibility and assignment workflow is genuinely valuable. Tenon returns JSON — useful for developers, but not usable by content editors or accessibility managers without custom tooling built on top of the API.

The Governance vs Pipeline Gap

Neither Silktide nor Tenon does the other's primary job well. Silktide can't be called from a CI pipeline to gate deployments. Tenon can't provide non-technical team members with an actionable dashboard showing what to fix and who's responsible. This is why large organizations sometimes run both — different tools for different layers of the accessibility program.

Pricing Comparison

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 driver: Number of pages monitored + feature tier

Tenon Pricing

Free tier: Very limited API calls — evaluation only
Commercial plans: Usage-based pricing; contact sales
Enterprise: Custom contracts with SLAs available
Pricing driver: API call volume + support tier

Silktide's pricing is clearly in the enterprise tier. Tenon's commercial pricing is more opaque — the free tier is too limited for production use, and the commercial tier requires a sales conversation. For developer teams evaluating Tenon specifically for CI/CD WCAG testing, it's worth noting that axe-core (open source, Deque Systems) provides comparable programmatic accessibility testing for free, with native integrations for Playwright, Cypress, Jest, and Selenium. This is often the first alternative teams evaluate before committing to Tenon's commercial API.

Frequently Asked Questions

Is Silktide better than Tenon for accessibility testing?

It depends entirely on who's using it and what for. Silktide is better for governance programs — enterprises, governments, and universities that need continuous monitoring, team workflow, and compliance dashboards without developer involvement. Tenon is better for development teams that need programmatic WCAG testing in CI/CD pipelines via REST API. They're not direct competitors; they address different layers of an accessibility program.

Does Silktide have an API like Tenon?

Silktide offers some API access for enterprise data export, but it's not designed as a developer-facing testing API the way Tenon is. Tenon's core product is its REST API — you send it a URL or HTML payload and receive structured JSON with WCAG violation data. Silktide's core is its SaaS governance platform. If you need a testing API to integrate with your own code or CI/CD system, Tenon is the right tool; Silktide is not built for that use case.

What is a free alternative to Tenon for CI/CD?

axe-core (Deque Systems, open source/MIT) is the most widely used free alternative for CI/CD accessibility testing. It integrates natively with Playwright, Cypress, Jest, and Selenium, and powers Google Lighthouse. For teams evaluating Tenon specifically for pipeline integration, axe-core achieves most of the same outcomes at no cost. Tenon's differentiators over axe-core include confidence scoring, a managed API with SLA options, and HTML payload testing.

Can I use Silktide and Tenon together?

Yes — they don't compete for the same function. Tenon in your CI/CD pipeline catches code-level regressions before deployment. Silktide on the production site provides continuous monitoring, content quality tracking, and team remediation workflow. Large organizations with both a development pipeline and large editorial web teams sometimes run complementary tools at both layers. The combined cost is significant, so evaluate carefully whether you need both layers or whether one tool covers enough of your requirements.

Which tool is better for UK government accessibility compliance?

Silktide is better suited for UK government PSBAR compliance. It has significant adoption in the UK public sector and is built with the monitoring, reporting, and workflow features that large government web estates require. Tenon can perform WCAG scanning, but its API-first design doesn't provide the governance dashboards or compliance reporting that UK public bodies need for PSBAR obligations.
