Best Tenon.io Alternative After Its Acquisition by Level…

Item: Tenon.io
Author: Editorial Team

Quick Verdict

Tenon.io was a well-regarded API-based accessibility scanner used by developers and agencies. After its acquisition by Level Access, product direction and independent availability became uncertain. A11yProof is an independent alternative that provides programmatic WCAG scanning plus AI-generated code fixes, starting at $29/month with an API included at the Agency tier.

Tenon.io: Acquired by Level Access, future uncertain

Feature	Tenon.io	A11yProof
Monthly cost	Acquired — future uncertain	from $29/month
Setup fee	Varies	$0

A11yProof offers the same core features at from $29/month with zero setup fees — vs. Tenon.io at Acquired — future uncertain.

Tenon.io Was a Good Tool in an Uncertain Position

Tenon.io built a reputation as a developer-first accessibility scanning API. It detected a wide range of WCAG violations, integrated cleanly into CI/CD pipelines, and provided programmatic access at pricing developers could work with. Accessibility specialists and agency developers relied on it for automated scanning workflows.

The acquisition by Level Access changed the picture.

Enterprise acquisitions change product priorities. Level Access is an enterprise accessibility platform. When an enterprise company acquires a developer-focused tool, the product typically moves upmarket — pricing adjusts, standalone availability becomes uncertain, and the roadmap shifts toward what serves the acquirer’s primary enterprise buyers. The independent, affordable API that developers chose Tenon for may not survive the integration intact.

The uncertainty itself is a reason to look around. Teams running Tenon’s API in production workflows don’t want to discover that pricing has changed or the standalone product has been discontinued at renewal time. Evaluating alternatives before that happens is the practical move, not an overreaction.

Tenon had a gap A11yProof fills. Tenon’s API returned violation data. Your developers received a list of WCAG issues and had to figure out the correct code fix for each one. That workflow works for specialized accessibility engineers, but it requires expertise and time. A11yProof returns the same violation data plus production-ready code changes — reducing the developer time between scan findings and committed fixes.

A11yProof as a Tenon.io Alternative

A11yProof is an independent product built for SMBs and agencies. It scans for WCAG 2.1 AA violations, generates code fixes, and produces VPAT compliance reports. Pricing is transparent: $29/month Starter, $79/month Pro, $199/month Agency.

The API is included at the Agency tier. Like Tenon’s API, it supports programmatic scanning for CI/CD integration. Unlike Tenon, it returns code fix output alongside the violation data — so developers get actionable changes, not just a list to work from.

No acquisition risk. No enterprise repositioning in progress. The pricing and product are what’s on the page.

Who Might Still Stay with Tenon.io

If Tenon’s API continues operating at its original terms post-acquisition, teams that have already integrated it may reasonably stay. The scanning quality was solid and existing integrations represent sunk engineering work. The core question is whether you’re comfortable with the roadmap uncertainty and the possibility of pricing or availability changes. If you want a clean evaluation against a stable independent alternative, A11yProof is built for that comparison.

Q&A

What happens to teams using Tenon.io's API after the Level Access acquisition?

Level Access has not publicly committed to maintaining Tenon's independent API product at its original pricing and terms. Enterprise acquisitions often result in products being repositioned upmarket or bundled into larger contracts. Teams using Tenon's API for accessible developer workflows should plan for the possibility that standalone Tenon availability changes and identify alternatives now rather than when a contract renewal creates urgency.

Q&A

Can A11yProof replace Tenon.io's API in a CI/CD pipeline?

A11yProof's API, available on the Agency plan at $199/month, can be integrated into CI/CD workflows to trigger automated scans and retrieve violation data. Unlike Tenon's API which returned scan data only, A11yProof's API returns scan results plus the code fixes for each violation. For teams using Tenon to gate deployments on accessibility violations, A11yProof provides the same capability with fix generation added.

Q&A

What should I look for in a Tenon.io alternative?

Key criteria for a Tenon replacement are: stable independent ownership (not recently acquired), a developer-friendly API at accessible pricing, accurate WCAG 2.1 AA detection, and a clear product roadmap. If fix generation is important to your workflow, that's an additional differentiator. A11yProof meets the first three criteria as an independent product with published pricing, and adds code fix generation that Tenon didn't provide.

PROS & CONS

Tenon.io

Pros

Developer-friendly API that integrated well into CI/CD pipelines
Reliable detection of a wide range of WCAG violations
Trusted by accessibility professionals for automated testing workflows
Lightweight, focused tool without enterprise platform overhead

Cons

Acquired by Level Access — product roadmap and independent pricing are now uncertain
Availability and pricing terms may change as Level Access integrates the product
No code fix generation — returns violation data, fix implementation is on your team
Future as a standalone product is unclear; may be folded into Level Access enterprise offering
Small teams and agencies may lose access to affordable developer API tiers post-acquisition

Is Tenon.io still available after the Level Access acquisition?

At the time of publication, Tenon.io exists as part of Level Access following the acquisition. However, product direction for acquired tools often shifts toward the acquirer's enterprise market. Teams relying on Tenon for accessible, developer-friendly API scanning should evaluate alternatives in case pricing or availability changes as the integration proceeds.

Why did Level Access acquire Tenon.io?

Level Access acquired Tenon.io to add API-based scanning capabilities to its enterprise platform. From Level Access's perspective, this extends their enterprise offering. For the independent developers and agencies who used Tenon as a lightweight scanning API, the acquisition introduces uncertainty about whether the product will remain accessible at the pricing tiers they relied on.

What makes A11yProof a stable Tenon.io alternative?

A11yProof is an independent product built specifically for SMBs and agencies, not an acquisition folded into an enterprise platform. The pricing is transparent, the API is included at the Agency tier ($199/month), and there's no uncertainty about whether the product will be repositioned for enterprise buyers. You can sign up today at published rates without a sales conversation.

Does A11yProof have an API like Tenon.io had?

Yes. A11yProof's API is included in the Agency plan at $199/month. You can trigger scans programmatically and retrieve violation data with code fix output — suitable for integrating into CI/CD pipelines or automated testing workflows. Tenon's API was developer-friendly and similarly positioned; A11yProof's API adds fix generation on top of scan results.

How accurate is A11yProof's scanning compared to Tenon?

Both tools detect WCAG 2.1 violations through automated scanning. A11yProof runs a 3-pass scan against your live site. The meaningful difference beyond scanning is that A11yProof generates production-ready code fixes for each violation found, while Tenon returned violation data for your team to act on. A11yProof reduces the developer time between scan findings and resolved issues.
