This inactivity has deepened user frustration regarding script persistence and memory performance. **Overall trend**: Declining **Compared at**: 2026-07-30 ### High-impact changes - **[Shifted] Development Velocity** (positioning) - **[Declined] Review Volume and Rating** (sentiment) ### Medium-impact changes - **[Shifted] Feature Consolidation** (features) - **[Added] Performance and Stability Weaknesses** (swot) ## Rivals Landscape {#rivals} > Competitive positioning identified by AI analysis of app features, category, and market signals. ### Userscripts vs Stay - Userscript Manager - **Stay - Userscript Manager** by Maple Labs Co., Ltd: Stay is the most direct commercial rival, offering a polished, feature-rich Safari extension specifically designed for userscript management with a significantly larger active user base. - **Key differences:** - Integrated script search and discovery within the app - More advanced visual editor with better mobile optimization - Support for a wider range of Greasemonkey/Tampermonkey APIs ### Contenders (Strong Challengers) - **Tampermonkey** by Jan Biniok: The industry standard for userscripts globally; while its iOS presence is smaller than its desktop counterpart, it remains a top-of-mind alternative for power users. - Paid upfront model ($1.99) vs Userscripts' free model - Longest-standing reputation for script compatibility and API support - **Hyperweb** by Marius Horga: A multi-purpose Safari 'super-extension' that includes custom JS/CSS injection as a core feature alongside ad-blocking and UI tweaks. - All-in-one utility approach (Dark Mode, Ad-block, Scripts) vs Userscripts' single-purpose focus - Highly automated 'suggested enhancements' for popular websites ### Peers (What They Do Better) - **Inspect Browser** by Matteo Mazzarolo: A dedicated browser for developers that allows live inspection and modification of web elements, sharing the same technical audience. - Full DOM inspection and console access on mobile - Standalone browser environment rather than a Safari extension - **AdGuard** by Adguard Software Ltd: While primarily an ad-blocker, its advanced userscript support makes it a common tool for users looking to manipulate web content. - Massive scale and brand recognition in the privacy space - Focus on content filtering and security over general-purpose script execution ### New Kids on the Block (What's Innovative) - **Web Inspector** by Sagi Lowenhardt: A newer, lightweight Safari extension that brings desktop-class developer tools (including script execution) to mobile Safari. - Focuses on real-time debugging and inspection rather than persistent script management - Modern, native iOS interface designed for quick edits ## What's New - **Latest (v1.8.6, 6 months ago):** Optimized memory management to resolve crashes with large metadata scripts and excessive script counts. ## App Momentum (Zombie) {#momentum} - Last major release 6 months ago. - Ships maintenance updates for memory management. > **Cadence:** 1 total versions · 0 majors in last 6 months · 199 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Userscripts is a market-leading developer tools app that is completely free. With a 4.39/5 rating from 173 reviews, it delivers strong user satisfaction. > **Bottom Line:** Addressing the background script-loading reliability is the critical path to retention, as the current manual re-enabling requirement creates high friction for power users. **Best for:** Power users and web developers who want to customize browser behavior and site styling on Safari. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Rebuild background script-loading logic because it is the top-cited reliability complaint → improve retention ### Outlook: Stable The market for Safari-based script management is consolidating around privacy-focused, open-source tools. Userscripts remains advantaged by its trust-based positioning, but the 6-month release gap leaves it vulnerable to performance regressions that could drive users to more actively maintained alternatives. - 🔴 Persistent script-loading failures force manual app re-opening, which erodes the utility of the automation users expect. - 🟢 The open-source, non-predatory model continues to drive high trust and positive sentiment among the core power-user base. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.39/5 | | Total Reviews | 173 | | Sentiment | Excited (75/100) | | Confidence | High | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Userscripts** (this app) | 4.39/5 | Excited | Justin Wasack | | [18 Strings](https://marlvel.ai/apps/18-strings) | N/A/5 | N/A | Remote Sunrise LTD | | [1min AI](https://marlvel.ai/apps/ai-ai1min-app) | 4.5/5 | Excited | 1min AI | | [[3D] Preview](https://marlvel.ai/apps/3d-preview) | 3.0/5 | N/A | designmatic | | [a11yTools - Web Accessibility](https://marlvel.ai/apps/com-pauljadam-a11ytools) | 4.2/5 | N/A | PaulJAdam.com | | [Accessibility Checker](https://marlvel.ai/apps/accessibility-checker) | N/A/5 | N/A | Manicgrin Media Ltd | ## Company Profile - **Developer:** Justin Wasack - **Website:** [https://github.com/quoid/userscripts](https://github.com/quoid/userscripts) - **Social:** [Instagram](https://www.instagram.com/github) · [X/Twitter](https://twitter.com/github) · [YouTube](https://www.youtube.com/github) · [TikTok](https://www.tiktok.com/@github) · [LinkedIn](https://www.linkedin.com/company/github) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/userscripts/id1463298887?uo=2) - **Dev Site:** [Official Website](https://github.com/quoid/userscripts) - **Sources:** Developer website content, About us / company information, App store metadata, User reviews. ## Related Intel Reports - [*18 Strings*](https://marlvel.ai/apps/18-strings) (Remote Sunrise LTD) · N/A Rating - [*1min AI*](https://marlvel.ai/apps/ai-ai1min-app) (1min AI) · 4.5/5 Rating | Positive Sentiment - [*[3D] Preview*](https://marlvel.ai/apps/3d-preview) (designmatic) · 3.0/5 Rating - [*a11yTools - Web Accessibility*](https://marlvel.ai/apps/com-pauljadam-a11ytools) (PaulJAdam.com) · 4.2/5 Rating - [*Accessibility Checker*](https://marlvel.ai/apps/accessibility-checker) (Manicgrin Media Ltd) · N/A Rating - [*Accessibility Inspector*](https://marlvel.ai/apps/accessibility-inspector) (George Garside) · 2.0/5 Rating - [*Accessory Developer Assistant*](https://marlvel.ai/apps/accessory-developer-assistant) (Apple) · 4.0/5 Rating - [*Adaptivity (A)*](https://marlvel.ai/apps/com-hacknicity-adaptivity-a) (Geoff Hackworth) · 5.0/5 Rating - [*ADB Connect & Debugger for ATV*](https://marlvel.ai/apps/com-mext-adbmaster) (小玲 王) · 3.7/5 Rating - [*AdDash‎ ‎*](https://marlvel.ai/apps/addash) (Hrishi Suthar) · N/A Rating ## Frequently Asked Questions {#faq} ### Is Userscripts safe to use for my custom scripts?

Yes, Userscripts supports cross-device synchronization of script files between macOS and iOS via iCloud folder selection. ### Why do my scripts stop working after a few days? Users report that scripts sometimes become inactive, requiring manual intervention within the app directory to re-enable them. ## Methodology {#methodology} This report was generated by Marlvel.ai's 5-stage AI intelligence pipeline: 1. **Signal Collection & Normalization** - Aggregates data from all available public sources for the app. Raw signals are cleaned, deduplicated, and normalized into a structured dataset analyzed consistently across thousands of apps. 2. **Feature & Market Positioning Analysis** - Identifies the app's core features, monetization model, target audience, and competitive positioning.
