Alfa vs Newt

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.

Newt is a free, open-source file manager for Linux, macOS, and Windows. Its two-pane interface handles local and remote filesystems, connecting through SSH, containers, Kubernetes pods, and WSL distributions. Remote sessions can run file operations, searches, terminals, and mounts on the remote host. Users can view, copy, move, delete, or edit files, and pack or reveal them. ZIP, TAR, compressed TAR, and CPIO archives can be browsed as directories, including nested and encrypted archives; ISO 9660 and UDF images can be browsed without extraction. S3 filesystems can be mounted, with range reads for large images. Recursive filename and content searches stream results into a pane linked to the files. Common actions have direct key controls, with configurable bindings and mouse controls also available. The backend uses Rust, while the interface uses React and TypeScript and packaging uses Tauri. Source code is available under the GNU GPL v3. No free-tier limits are stated.
