m3u8-downloader is a tool for extracting, downloading, and merging video segments from m3u8 playlist files into a single file. It functions as an HLS stream extractor and downloader that parses playlists to identify and retrieve individual video fragments. The project features a dedicated AES-128 stream decryptor to ensure encrypted media is playable and utilizes an MP4 transcoder to convert fragmented stream segments into a standard container for broad media player compatibility. It employs cross-origin script injection to bypass browser security restrictions and extract video source links d
Injects download logic into the context of the host video page to bypass cross-origin security restrictions.
pydoll is a Chrome DevTools Protocol automation library and headless browser controller used for web data extraction and parallel browser automation. It controls Chromium-based browsers via direct WebSocket connections, allowing it to manage isolated browser contexts and tabs while bypassing the overhead and detection associated with WebDriver. The project features an anti-bot evasion framework that mimics natural human behavior, including mouse movements generated via Bezier curves and variable typing patterns. It provides specialized stealth capabilities to bypass behavioral analysis and au
Executes custom JavaScript where the script references the target element as the execution context.
Userscripts is a Safari browser extension that installs and runs custom JavaScript and CSS on websites through Apple's content script injection system. It provides a privileged execution context that allows userscripts to perform cross-origin HTTP requests and access clipboard functionality beyond standard browser sandbox restrictions. The extension uses metadata tags like @match, @run-at, and @weight to control precisely when and where scripts execute on web pages. It includes a built-in code editor with syntax highlighting and linting for modifying scripts directly, and supports automatic s
Matching userscripts to specific domains using metadata tags and controlling injection timing and execution context per page.
Scriptcat is a user script manager and browser extension designed to install, execute, and manage custom JavaScript scripts to modify website behavior and extend browser functionality. It features a JavaScript sandbox environment that provides specialized APIs for storage, cookies, and system notifications, alongside a cloud-synced script repository to keep subscriptions and configurations consistent across multiple devices. The project includes an in-browser script editor for writing, testing, and debugging code directly within the browser. It also incorporates a cross-domain request engine
