Instead of Alfa

Alfa alternatives

Alfa is a free, open accessibility conformance engine for websites built with HTML, CSS, and JavaScript. It checks WCAG-based rules, accepts pluggable ACT Rules Format implementations, and can add custom rules or filter results by conformance level and WCAG version. Its scraper and crawler gather pages for auditing, while integrations connect with frameworks, browser automation, test runners, and CI/CD workflows. Alfa also offers a command-line audit for one page and returns EARL Schema results encoded as JSON-LD across supported JavaScript environments.

That developer-oriented approach may not suit teams seeking browser extensions, scheduled monitoring, manual reviews, or mobile testing. Alfa is distributed through separate npm packages, requires a compatible JavaScript environment, and most integrations are experimental and subject to change. When switching, weigh whether you need page-focused browser tools, broader evaluation methods, managed scanning, or remediation guidance. Check each option’s platform coverage, scan scope, WCAG 2.2 support, pricing, and integration path against Alfa’s free MIT-licensed model and customizable rules.
