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.
