Script Master

Take control of your browsing experience with ScriptMaster, the ultimate browser extension for injecting custom JavaScript into specific websites — all with rock-solid security and zero compromise on privacy. 🧠 No Coding Experience? No Problem! You don't need to be a programmer to use ScriptMaster. With today's tools like ChatGPT, you can ask for a script and paste it in — it's that simple. Whether you're tweaking a website's layout or automating repetitive tasks, ScriptMaster makes it accessible to everyone. 🔐 Security You Can Trust ScriptMaster goes beyond basic script injection with a state-of-the-art cryptographic validation system: Every script you define is digitally signed with a private key unique to your extension instance. Only those scripts that you explicitly create and sign are allowed to run. This protects you from potential attackers trying to sneak in malicious code. 🔒 100% Privacy. No Ads. No Tracking. I respect your privacy. ScriptMaster is: Completely free Ad-free and tracking-free Not collecting any of your data All scripts and settings are stored locally on your own device — nothing ever leaves your browser. ⚙️ Built for the Future with Manifest V3 ScriptMaster is built using Manifest V3, the latest and most secure extension platform officially supported by Chrome. Unlike many older script-injection tools based on Manifest V2 (which will stop working in 2025), ScriptMaster is designed for long-term compatibility and support. ✨ Key Features Run custom JavaScript on any site using simple URL patterns Support for both inline and remote scripts Manage multiple scripts with ease through an intuitive UI Auto-save your work, and edit or delete scripts anytime Built with modern technologies like Vue.js and TypeScript 🔧 How It Works Install ScriptMaster from the Chrome Web Store. Open the extension and enter a URL pattern (e.g., *://*.example.com/*). Paste your JavaScript or a script URL. Save and go — your script will run automatically on matching sites. 🆕 Script Import with Security Controls ScriptMaster now makes it even easier to add scripts: you can import scripts directly from supported web pages. When you click the import button on a page, ScriptMaster opens an import window where you can review and edit the script before saving it. Security remains my top priority: You have full control to accept or reject every script before it runs. You can block future import attempts from any page you consider untrustworthy. A new Blocked Sites list lets you manage and unblock sites at any time. This makes ScriptMaster more flexible and powerful, while keeping you protected against unwanted or malicious imports.
