Accessibility Tracker vs Alfa

Accessibility Tracker helps teams manage accessibility audits, remediation, validation, and documentation. Users can upload WCAG audit reports in Excel format, then track issues with their page locations, criteria, code snippets, and recommended fixes. Issues can be prioritized using legal-risk lawsuit data or a weighted user-impact score, assigned across a team, and followed in a shared dashboard. Completed fixes can be sent to auditors for validation. The service also provides one-time and scheduled page scans, but automated scans flag approximately 25% of accessibility issues. Five AI tools help explain issues, offer technical answers and alternatives, provide WCAG context, and support custom analysis; AI can also fill VPAT templates for review. The platform supports ADA compliance, EAA conformance, and VPAT or ACR preparation. A webpage can be scanned without an account, and the free trial requires no credit card. The free plan includes one project and 100 issues. Paid plans start at $19 a month, with higher tiers and add-ons available.

Alfa is a free, open accessibility testing engine for websites built with HTML, CSS, and JavaScript. It checks pages against accessibility standards such as WCAG, using included rules or pluggable rules in the ACT Rules Format. Developers can add custom rules and filter results by conformance level or WCAG version. Audit output follows the Evaluation and Report Language schema as JSON-LD, and the command-line interface can audit a single page and save results as JSON. Scraper and crawler tools create page representations and discover pages across a site or subdomain. Ready-made integrations cover frameworks and test tools including Angular, React, Vue, Cypress, Jest, Playwright, Puppeteer, Selenium, and WebdriverIO. Alfa is distributed as separate npm packages under the MIT license. It runs in ECMAScript 2022-compatible JavaScript environments, including recent Node.js and browser versions. Building from source requires Node.js 20 or later and Yarn. The project says most integrations are experimental and may change; older environments may be targetable from source but are not explicitly supported.
