Alfa vs Rat Commander

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.

Rat Commander is a free, two-panel terminal file manager for Linux, macOS, and Windows. It brings file browsing and media viewing together with editing, archives, Git, remote filesystems, and system tools. Panels can show files as lists, trees, thumbnail grids, or interactive 3D views, and can be split vertically or horizontally. The built-in viewer and editor support syntax highlighting, search and replace, Markdown, tables, images, and in-place hex editing. Git tools cover tasks including staging, commits, branches, diffs, and history. Remote connections over SFTP, SCP, FTP, and FTPS let users work with remote filesystems in a local-disk-like way. ZIP, TAR variants, 7z, and other archives can be browsed and edited; RAR is read-only. QR codes support sending and receiving files over a local network. Linux disk tools can mount, format, flash, and image disks and USB devices. On Windows, Drive Manager and Network Connections are unavailable. Rat Commander is written in Rust with Ratatui and is licensed under GNU GPL-2.0-only.
