In their own words
Octopus Scanner (formerly A11y Scanner)
Octopus Scanner, formerly A11y Scanner, is a free desktop tool for auditing website accessibility on Windows and macOS. It uses browser automation and axe-core-powered checks to scan sites against WCAG 2.2; setup also supports requirements including Section 508 and EN 301 549. It can record and replay authenticated flows such as logins and checkouts without code, and handle dynamic interfaces, Shadow DOM, embedded frames and dark mode. Scans produce an interactive HTML report and a companion CSV, and the tool can check the structure of linked PDF documents. Scanning, analysis and reporting stay on the local machine. Scanned-site traffic can be routed through HTTP, HTTPS or SOCKS proxies. Optional update checks use official checksums and signatures, and updates can be reverted. The Windows download is 64-bit and the macOS download is ARM64. Listed version 5.0.9.8 is marked beta. The software is free; contributions to its independent developer are optional.
WAVE
WAVE is a web accessibility tool that identifies many accessibility and WCAG errors and provides tools for human evaluation of web content. Its browser extensions for Chrome, Firefox, and Edge can examine password-protected, locally stored, and highly dynamic pages. The service supports page scans, scheduled site audits, intranet pages with most authentication types, and custom viewport sizes for checking responsive breakpoints. Stand-alone tools can integrate with continuous-integration systems including Selenium and Puppeteer. The API returns JSON or XML; basic analysis uses one credit, while advanced features may use two or three. New accounts receive 100 free API credits. Subscription API access has a 250-credit minimum purchase for $10 a month. Stand-alone API licenses cost $4,000 a year for Basic, $8,000 a year for Expanded, and $12,000 a year for Unlimited. The stand-alone API runs on Linux, Mac, or Windows web servers with PHP and Node installed; minimum requirements are 1 CPU, 1 GB memory, and 100 MB storage.
