accesslint

Catch accessibility failures before your users do.

Accessibility is not optional. In 2025.

It happens on every project. An image without alt text. A button made from a div. A form input with no label. A click handler with no keyboard equivalent. A modal that traps focus with no escape.

WCAG 2.1 is the global standard for web accessibility, and lawsuits for non-compliance have increased 300% since 2018. The automated scanner catches it in staging. After the complaint.

AccessLint catches accessibility violations before they leave your machine. Pre-commit hooks. Local scanning. 95+ patterns across HTML, JSX, Vue, and Svelte. Zero data leaves your laptop.

Quick Start

# 1. Install via ClawHub (free)
clawhub install accesslint

# 2. Scan your repo
accesslint scan

# 3. Install pre-commit hooks (Pro)
accesslint hooks install

That's it. Every commit is now scanned for accessibility violations.

What It Does

Scan templates for accessibility violations

One command to scan any file, directory, or your entire repo. 95+ regex patterns detect missing ARIA attributes, semantic HTML failures, keyboard navigation gaps, form accessibility issues, color/visual problems, and dynamic content failures across HTML, JSX, Vue, and Svelte.

Block commits with pre-commit hooks

Install a lefthook pre-commit hook that scans every staged template file. If an accessibility violation is detected, the commit is blocked with a clear remediation message.

Generate accessibility reports

Produce markdown reports with severity breakdowns, WCAG 2.1 success criterion mapping, and remediation steps. Ideal for accessibility reviews and compliance audits.

Deep accessibility audits

Analyze component-level accessibility, ARIA coverage, heading hierarchy, landmark regions, and form labeling patterns with the deep audit command.

Enforce accessibility policies

Define organization-specific policies (required alt text, banned inaccessible patterns, mandatory ARIA labels) and enforce them alongside the built-in 95+ patterns.

WCAG 2.1 compliance reports

Generate comprehensive reports mapping findings to WCAG 2.1 success criteria (Level A, AA, AAA) with executive summaries, detailed findings, and remediation roadmaps.
