Tenon vs TPGi: Which Web Accessibility Solution Offers More?

Tenon vs TPGi — a concise comparison for teams choosing web accessibility tooling or services. This article compares each vendor’s positioning, testing scope, integrations, pricing approach, support and best-fit buyers so you can decide which to evaluate further.

Short answer

Tenon and TPGi serve different buyer needs. Tenon is typically selected by development teams that want an API-driven or developer-friendly automated testing workflow plus remediation guidance. TPGi is typically chosen by organisations seeking enterprise accessibility programmes: consultancy-led audits, training, manual testing and governance support. Neither vendor (nor any tool) can guarantee “full WCAG compliance”; both are parts of a programme that also needs manual review and policy work.

Quick comparison snapshot

Best for	Dev teams embedding automated checks in builds	Organisations building or maturing an accessibility programme with expert support

What is Tenon?

Tenon is a product positioned for teams that need automated accessibility testing they can run inside development workflows. It is commonly used where teams want an API, CI/CD integration and issue-level results developers can action. Tenon-focused evaluations should verify the tool’s coverage of specific WCAG success criteria you care about, how it flags false positives, and what manual or consulting services the vendor offers if you need expert audits.

What is TPGi?

TPGi (The Paciello Group International) is known for accessibility consultancy, audits, training and programme services aimed at enterprise customers. Organisations that need accessibility strategy, manual testing by experts, training for content and engineering teams, or governance and remediation programmes often evaluate TPGi. If you want an independent audit, remediation project management or tailored training, a consultancy-led vendor is usually the right starting point.

Feature comparison

Testing scope

Automated testing tools catch a share of programmatic failures (missing ARIA roles, colour contrast, missing alt attributes, etc.), but they cannot check many content and interaction issues that require human judgment. When evaluating Tenon and TPGi, treat automated results as triage: they uncover repeatable code-level problems, while manual expert review finds issues such as meaningful link text, complex keyboard flows, and cognitive accessibility concerns.

WCAG coverage and standards

Both vendors position themselves to help organisations meet WCAG-related obligations; however, automated checks cover only a subset of WCAG success criteria across A, AA and AAA levels. Confirm with each vendor which WCAG versions and levels their tooling or audits specifically map to, and whether they provide a VPAT or accessibility conformance report for your product.

Integrations and developer workflow

Teams that prioritise continuous integration and rapid feedback should prioritise an accessibility solution that offers an API, CI plugins, and clear issue payloads for ticketing systems. Likewise, enterprise programme owners should prioritise reporting exports, executive dashboards and evidence packages for legal or procurement audits. Check each vendor’s documentation for CI/CD examples and supported integrations.

Reporting, governance and remediation support

Compare the level of remediation guidance included in reports: some vendors provide code-level fixes and examples for developers; consultancies often include remediation roadmaps, prioritisation frameworks and project management support. If you require long-term governance (accessibility policy, procurement checks, training schedules), look for vendors that offer those services as part of a programme, not just one-off audits.

Pricing comparison

Pricing models in the accessibility market vary: automated tools commonly use subscription or consumption-based pricing, while consultancies price audits, training and remediation as projects or retainers. Public pricing details change and are not always published in full; request quotes from each vendor and compare what’s included (number of pages/scans, audit depth, remediation support, training days and licence seats).

Ratings and user feedback

Marketplaces such as G2, Capterra and TrustRadius often contain user reviews for accessibility vendors. Review counts and scores change; use those sites to read recent reviews and look for patterns in praise and complaints (accuracy of automated checks, quality of manual audits, client support responsiveness, and ease of remediation). For a fair comparison, compare reviews from the same time period and pay attention to the review date.

Ease of use and support

Developer-focused tools are generally easier to adopt for engineering teams if they offer clear APIs, example code and plugins for common CI systems. Consultancy vendors are measured by their ability to onboard organisations, run effective audits, and transfer knowledge through training. When evaluating support, ask each vendor about service-level agreements (SLAs), incident response processes, and how they handle follow-up audits after remediation.

Which one is right for you?

• Choose Tenon (or similar API-driven tools) if your priority is embedding automated checks into developer workflows, catching repeatable code errors early, and giving engineers machine-readable results they can act on.
• Choose TPGi (or a consultancy partner) if you need expert manual audits, bespoke training, governance and a remediation programme led by accessibility specialists for enterprise-scale compliance and policy.
• Consider both if you want automated scanning for day-to-day checks plus periodic expert audits and training to cover the gaps automation misses.

Verdict

The right choice depends on your goals: pick an API-first automated tool when you need developer integration and continuous checks; pick a consultancy when you need programme-level strategy, manual audits and training. For most mature accessibility programmes, a combination of automated tooling and specialist consultancy work delivers the best coverage and governance. Always verify current product capabilities, WCAG mappings and pricing directly with the vendors before purchasing.

FAQs

Can an automated tool (like Tenon) make our site fully WCAG compliant?

No. Automated tools detect many technical issues but cannot assess all WCAG success criteria. Manual testing and human judgement are required for full conformance.

Does TPGi provide automated tooling as well as consultancy?

TPGi is primarily known for consultancy, audits and training; some consultancies also offer or license tooling. Check the vendor’s current product and services pages to confirm what’s included.

Which approach is cheaper: automated testing or consultancy?

Automated testing is typically less expensive to run at scale, but it covers fewer types of issues. Consultancy costs depend on scope, depth and duration. Total cost of ownership should include remediation effort, not just licence or project fees.

How should we evaluate accuracy of automated accessibility reports?

Look for clear mappings to WCAG criteria, low false-positive rates in your codebase, code-level remediation guidance and the ability to silence or triage known issues. Pilot the tool on representative pages before committing.

Do either vendor guarantee legal compliance with accessibility laws?

No reputable vendor can guarantee legal compliance; they can help you reduce risk through testing, remediation and policy. Ask vendors about deliverables that help demonstrate due diligence.
