be-a11y is a Node.js-based CLI tool designed for automated evaluation and reporting of accessibility issues in HTML-based projects. It supports both local directory scanning and remote URL analysis to help developers identify common accessibility problems.
- Detects incorrect heading level order (e.g.,
h1
βh3
skipped) - Flags empty headings (
<h1>
β<h6>
) with no or whitespace-only content - Warns if multiple
<h1>
tags are present
- Verifies that
<img>
tags have appropriatealt
attributes- β¬ Flags empty
alt
attributes βοΈ Detects excessively longalt
texts (configurable)- π Ensures decorative images have correct
alt=""
or role attributes - π Highlights functional images (e.g., inside links/buttons) with empty
alt
- π Detects redundant
title
attributes that duplicate thealt
content - πΌοΈ Verifies
<iframe>
elements include a descriptive, non-emptytitle
attribute (assistive tech-friendly) (new!)
- β¬ Flags empty
- Validates
aria-label
andaria-labelledby
usage - Ensures
aria-labelledby
references valid IDs - Flags misuse of ARIA roles (e.g., non-interactive elements with
role="button"
) - Identifies missing landmark regions (
<main>
,<nav>
,<header>
, etc.)
- Detects elements missing accessible names (like
<button>
,<a>
,<svg>
, form fields) - Warns about unlabeled checkboxes and radio buttons
- π Checks that
<label>
elements are correctly associated with form controls (viafor
or nesting)
- Flags empty or placeholder
<a>
tags lacking text orhref
- Warns about duplicate
id
attributes in the same document - Warns when
target="_blank"
does not contains appropriatearia-label
for a new page
- Evaluates text/background contrast in inline styles
- Flags contrast below WCAG 2.1 AA threshold (4.5:1)
- Recursively analyzes files with extensions:
.html
,.php
,.latte
,.twig
,.edge
,.tsx
,.jsx
- Ignores common build directories (
node_modules
,vendor
,dist
, etc.) - Accepts URLs and fetches remote pages for evaluation
- CLI output grouped and color-coded with file names and line numbers
- Returns non-zero exit code when issues are found
- Supports export of evaluation results to JSON
- Fully configurable via
a11y.config.json
- Enable or disable specific checks
- Fine-tune subrules (e.g., disable
alt-too-long
orredundant-title
)

The European Accessibility Act (EAA), effective from June 28, 2025, requires certain digital products and services to comply with accessibility standards across the EU.
While this tool does not guarantee full compliance, be-a11y supports teams in their evaluation efforts by:
β οΈ Detecting common accessibility issues as outlined in standards like WCAG 2.1- β Providing actionable findings to assist with remediation workflows
- π° Promoting awareness and adoption of inclusive development practices
