Building Accessible Applications

Accessible User Interfaces with SAIL

The Appian platform allows designers to build applications that are accessible to all users, including those with disabilities who employ assistive technologies such as screen readers. In order to meet this goal, Appian validates its product features against the requirements of leading accessibility standards:

Since each screen reader is optimized to work best with a particular browser, Appian recommends the following common combinations of browser and screen reader:

Browser Screen Reader
Mozilla Firefox NVDA
Internet Explorer 11 JAWS

Accessibility capabilities within Appian’s SAIL technology features allow users with low vision, limited dexterity, and other concerns to consume the same information and perform the same activities as any other user of an application. Many of these capabilities are automatically enabled when using interfaces, while others are activated by making use of appropriate interface component configuration parameters. Accessibility-related configuration recommendations are described in detail on each interface component documentation page. Example: hidden labels

Interface Components with Accessibility Limitations

A small number of interface components, due to their specialized functionality, may not be accessible to all users.


Charts represent data in a graphical fashion and may not be usable by blind users or those with low vision. In addition, some charts support navigation (drill down) via mouse clicks and this capability is not available to users who rely exclusively on keyboard inputs.

For an accessible alternative, provide the data in a grid instead. See this recipe for an example.

Hierarchy Tree

The hierarchy tree component shows object relationships in a graphical fashion and may not be usable by blind users or those with low vision.

For an accessible alternative, provide the data using a column hierarchy browser instead.

Rich Text

Rich text with positive styling does not meet color contrast requirements and may not be usable by users with low vision.

For an accessible alternative, replace positive styling with normal styling. Positive-style icons can be used in conjunction with normal-style text. This pattern is compliant as WCAG 1.4.3 is a contrast requirement for text only.

Styled rich text items are not interpreted as HTML headings by screen readers. Rich text headers should be used to represent content sections in an accessible way.

Document Extraction Reconciliation Task

The Reconcile Doc Extraction Smart Service generates a task for a user to validate the extracted data. This task requires users to visually inspect an image of a document to validate correct extraction of its contents. Therefore, this feature may not be usable for blind users or those with low vision. To learn more about this task, see the Appian Document Extraction page.
