About OpenScript
OpenScript is a fast, lightweight, and modern user script manager built for Chrome Manifest V3.
Run custom JavaScript on your favorite websites, automate repetitive tasks, and inject synced environment secrets with zero bloat.
KEY FEATURES:
• Built for Manifest V3: Uses the native chrome.userScripts API for maximum performance and security.
• Synced Secrets: Store API tokens and secrets securely across your devices with chrome.storage.sync (accessible via OpenScript.env or env).
• Per-Script Storage: Isolated, persistent key-value storage for each script via OpenScript.storage (get, set, list, delete).
• External Libraries (@require): Cache remote scripts offline and bypass site CSP restrictions.
• Modern Async Runtime: Direct top-level await and return without boilerplate wrappers.
• Fast Built-in Editor: Write and edit scripts in the popup with metadata support (@name, @match, @run-at, @require).
• Filter & Search: Quickly toggle, search, and manage your scripts.
• 100% Open Source & Privacy-First: No tracking, no telemetry, and no external servers.
