Description
Inject javascript and css into pages dynamically. Moonly – lets you inject custom JavaScript and CSS into any web page. Create scripts, set conditions for when they run, and manage everything through a clean, built-in editor. What you can do: - Inject JavaScript or CSS — write either in a full-featured code editor (syntax highlighting, line numbers, bracket matching, and a choice of editor themes) - Run scripts manually with one click from the popup, or automatically when a page matches your conditions - Match pages by exact URL, substring, or regex pattern - Control injection timing — run JavaScript before the page loads or after (CSS is applied early, with no flash of unstyled content) - Organize your library — search, duplicate, reorder, and enable/disable scripts - Import and export scripts as JSON, one at a time or all at once, for backup or sharing Built for developers, testers, and power users who want to automate repetitive tasks, test page behavior, or customize their browsing experience. Permissions: - Tabs — detect the active page for script matching - Scripting — inject your JavaScript and CSS into pages - Storage — save your scripts locally on your device Scripts are stored entirely on your device and never sent anywhere. No data is collected. Use responsibly — only run scripts you trust.
