Alfa vs Runa

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.

Runa is a free terminal file manager written in Rust for Linux, macOS and Windows. Its keyboard-driven interface provides dual-pane browsing, a preview pane, tabs, and actions for moving, filtering, copying and renaming files. Keybindings, colors and layout can be changed in a TOML configuration file. The project describes a multithreaded engine with dedicated worker threads for input/output, previews, search and file operations. An optional fd installation enables recursive fuzzy search across files and folders; without fd, Runa remains usable but cannot perform that search. The optional bat tool adds syntax-highlighted previews, while built-in preview methods work without it. Installation is available through Cargo, Arch Linux AUR, Homebrew, Scoop, precompiled binaries or source builds. Releases from v0.5.11 are described as immutable and include attestations and SHA256 checksums. Runa is dual licensed under MIT or Apache-2.0 and remains under active development.
