Accessibility statement

Our commitment

Denpex is a diagnosis tool for distributed GPU training failures. The people who use it are on call at three in the morning trying to work out why a run died. That job should not additionally require a mouse, a steady hand, or the ability to distinguish red from green.

We are committed to making denpex.com and the Denpex console usable by everyone, including people who navigate by keyboard alone, use a screen reader or other assistive technology, rely on browser zoom or increased text size, or need reduced motion.

Conformance status

The Web Content Accessibility Guidelines (WCAG) define requirements for making web content more accessible to people with disabilities. It has three levels: A, AA and AAA.

Denpex is partially conformant with WCAG 2.1 Level AA. “Partially conformant” means that most of the standard is met, but some content does not yet fully conform. We describe what we know does not conform under “Known limitations” below, rather than leaving you to discover it.

What we have done

In August 2026 we audited the entire front-end codebase against the four POUR principles and remediated every defect the audit confirmed. Specifically:

  • Colour and contrast. Body text, labels, and interactive controls meet the 4.5:1 minimum against their background; large text and control boundaries meet 3:1. Our brand orange did not pass as text at small sizes, so it is now used as a fill and a lighter variant carries text. Status is never signalled by colour alone — every coloured indicator is accompanied by text or an icon.
  • Keyboard operation. Every interactive element, form, and navigation menu can be reached and operated with a keyboard alone. Dialogs trap focus while open, close on Escape, and return focus to the control that opened them. Focus indicators are visible on every focusable element.
  • Assistive technology. Pages use semantic HTML with a single main landmark and a sequential heading outline. Custom controls expose the correct ARIA role and state. Results that appear asynchronously — a diagnosis, a copied value, a validation error — are announced rather than appearing silently.
  • Forms. Every input has a programmatically associated label. Errors are tied to their field, announced, and say how to correct the input rather than only that it is wrong.
  • Motion.Animated demonstrations honour the operating system's “reduce motion” setting, and animations that would otherwise run indefinitely can be paused.

How we assessed it

Denpex self-evaluated the platform. The assessment combined a manual review of all front-end components with an automated suite that loads each public page in a real browser and measures the rendered result — contrast is computed from composited pixels rather than inferred from stylesheets, and keyboard behaviour is exercised by actually pressing Tab and Escape.

That suite runs against production on every release, so a regression is caught rather than discovered by a customer. It last passed in full on August 13, 2026.

We have not yet commissioned an independent third-party accessibility audit, and we do not claim one. Nor have we tested with a formal panel of assistive-technology users. Both are on our roadmap, and neither is something we will assert here before it has actually happened.

Known limitations

We would rather tell you these than have you find them:

  • Failure Encyclopedia pages. Roughly 2,760 pages are generated from a shared template. The template is assessed and conforms; individual entries are not each reviewed by hand, so an entry whose source content is unusual may present a heading or wording issue the template cannot correct.
  • Cluster topology and causation diagrams. These convey relationships between GPUs, ranks and network links. They carry a text alternative describing the finding, but a complex fabric diagram is inherently harder to consume non-visually than the summary we provide alongside it. If you need the underlying data in another form, ask us and we will send it.
  • Third-party content. Checkout is handled by Stripe and some documentation embeds external content. We do not control the accessibility of those surfaces, though we do choose vendors with that in mind.

Tell us about a barrier

If you hit something on Denpex you cannot use, we want to know — and we will treat it as a defect, not a feature request.

Please tell us the page, what you were trying to do, and the assistive technology and browser you were using, if you know them. Any detail helps; none is required.

We aim to respond within one business day and to agree a fix or a workaround with you from there. If a fix will take longer than that, we will tell you what we are doing and when to expect it, rather than going quiet.

If we do not resolve it

If you are not satisfied with our response, say so directly in the same thread and it will be escalated. You retain any rights you have under applicable accessibility law in your jurisdiction — including, in the United States, the Americans with Disabilities Act, and in the European Union, the European Accessibility Act — and nothing on this page limits them.

Technical details

Accessibility of Denpex relies on HTML, WAI-ARIA, CSS and JavaScript. The platform is tested against current versions of Chrome, Firefox, Safari and Edge on desktop and mobile.

A note on accessibility overlay widgets: we do not use one. Overlays that promise to make a site conformant automatically do not reliably do so, and we would rather fix the underlying markup — which is what this statement describes.
