After ViolentMonkey's demise of Manifest v2, ScriptCat looks promising but fails to deliver even close performance or UI features. If you check their site (mostly Chinese), you'll see even it advertises itself to be a TamperMonkey clone. TamperMonkey is literally the oldest script manager there's so I'd rather switch back to it instead of switching into this unknown extension. I recently checked my extension collection and saw lots of extensions either being banned or removed due to their practices so sticking with TamperMonkey instead of having to remove ScriptCat in the future for another reason.

I have scripts that auto-fill forms and check prices. ScriptCat runs them in the background without needing a tab open perfect.

有点小怀旧目前这个列表式脚本排列还是有点乱在长屏情况下显示不太友好可能比较习惯暴力猴这种

Userscript manager that executes, manages, and organizes user scripts (Greasemonkey/Tampermonkey compatible) in the browser with a built-in code editor

Enables users to customize web pages, automate repetitive browser tasks, and extend website functionality through user scripts — with additional support for background scripts, scheduled tasks, and cloud sync that exceed typical userscript managers

1. Install extension from Chrome Web Store (free, no login required). 2. Open options page with full Monaco editor to write/import/subscribe to user scripts. 3. Scripts auto-run on matching pages or run continuously in background. 4. Optionally configure cloud sync to back up scripts to user's own cloud storage (WebDAV, Google Drive, etc.). 5. Optionally subscribe to script lists for auto-updates.

Target users: Power users who need advanced userscript management beyond Tampermonkey / Developers who want a built-in editor and linting for script development / Users who need background/scheduled script execution / Users who want cloud sync across devices/browser reinstalls / Automation enthusiasts for browser task scheduling

Source code is heavily minified/webpack-bundled making exact line-level analysis difficult for some features
Could not verify if scriptcat.org website has paid features for script hosting (separate from the extension)
The extension integrates with many cloud storage APIs but these are user-configured, not ScriptCat-provided services

Monetization

No paid features detected

The heuristic detected 'subscription', 'subscribe', and 'upgrade' keywords, but these are false positives: 'subscribe' refers to the script subscription feature (subscribing to user script update sources, like RSS feeds for scripts), 'subscription' appears in Monaco editor library internals, and 'upgrade' refers to Dexie database schema upgrades and Monaco editor code. No payment processing (Stripe, billing APIs), premium tier gating, upgrade prompts, license checks, or paywall UI was found. The extension is open-source on GitHub (scriptscat/scriptcat) with no evidence of monetization within the extension itself.

Confidence: 88
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension operates entirely locally with IndexedDB (Dexie) for storage. The 'login/auth' keyword matches in static analysis are false positives: 'auth' appears as part of 'author' in TypeScript type definitions, 'session' is a boolean flag for script types, 'token' appears in Monaco editor tokenizer code, and 'jwt' is in Chrome Web Store metadata. Cloud sync is an optional feature connecting to user-configured storage services (WebDAV, Google Drive, OneDrive, Dropbox, Baidu Pan, S3), not a ScriptCat account system. No login UI, authentication endpoints, or account creation flow was found in the codebase.
