The rivals identified
The Nemesis
Stay Slim, Weight Loss - Hypnosis & Meditation
★3.0 (2)Hypnosis & Subliminal
💀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.
Head to Head
Stay currently holds the market edge due to its superior script discovery and polished UI, but Userscripts remains the preferred choice for privacy purists and developers who demand an open-source, non-commercial tool.
What sets Userscripts apart
Completely free and open-source with no monetization or 'Pro' tiers
Privacy-first architecture with zero user tracking or data collection
What's Stay - Userscript Manager's Edge
Significantly higher rating count (~1.7k vs 172) indicating broader market adoption
Built-in 'Stay Fork' community for sharing and downloading scripts directly
Contenders
Paid upfront model ($1.99) vs Userscripts' free model
Longest-standing reputation for script compatibility and API support
Peers
Full DOM inspection and console access on mobile
Standalone browser environment rather than a Safari extension
AdGuard Pro: Safari Ad Blocker
★4.4 (2.9K)Adguard Software Limited
⚡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
Web Inspector & Dev Tools
★5.0 (1)VISUAL MOBILE SOFTWARE S.R.L.
⚡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
The outtake for Userscripts
Strengths to defend, gaps to attack
Core Strengths
- Open-source transparency and high user trust
- Completely free with no monetization or 'Pro' tiers
- Privacy-first architecture with zero data collection
- Cross-device synchronization via iCloud
Critical Frictions
- Script persistence bugs where scripts stop running automatically
- High friction in initial setup and script installation
- Lack of a built-in script discovery/gallery interface
- Limited mobile editor capabilities compared to desktop
Growth Levers
- Integrate a curated, privacy-vetted script gallery to compete with Stay
- Improve onboarding flow to reduce 'stuck' users
- Market specifically to privacy-conscious users fleeing commercial extensions
Market Threats
- Stay's superior script discovery and community features
- Tampermonkey's dominant brand recognition and API support
- Potential Safari API changes affecting background script execution
What are the next best moves?
Resolve script persistence and background execution bugs.
This is the #1 complaint theme ('scripts automatically turn off') and a primary driver of negative sentiment and potential churn.
Redesign the onboarding and setup flow.
Users report being 'stuck on the informational screen,' indicating a UX barrier that prevents successful first-time use.
Implement a basic script discovery or 'Import from URL' gallery.
This addresses a major feature gap compared to the nemesis, Stay, which features an integrated 'Stay Fork' community for script sharing.
Feature Gaps vs Competitors
- Integrated script search and discovery (available in Stay)
- Advanced visual editor with mobile optimization (available in Stay and Web Inspector)
- Wider range of Greasemonkey/Tampermonkey API support (available in Stay and Tampermonkey)
Key Takeaways
Userscripts is the gold standard for privacy-conscious developers, but it is currently losing the 'ease-of-use' battle to Stay. While its open-source nature is a massive strength, the PM must prioritize fixing script persistence bugs and reducing onboarding friction to prevent power users from migrating to more reliable commercial alternatives.
Where Is It Heading?
Stable
v1.8.6 (Jan 2026) added memory optimization and iOS stability — active maintenance on core performance.
Rankings show a slight decline (↓1) in the Developer Tools category, suggesting increased competition.
User sentiment remains 'Positive' despite persistent technical complaints regarding script loading.
