Stay
Safari userscript manager that runs Tampermonkey scripts
As of 15 September 2026, Stay has a free plan and paid plans start at $5/one-time. Safari script manager for iPhone, iPad and Mac that runs its own scripts plus Tampermonkey and Violentmonkey ones, on a single one-time payment. Softwr lists it under Browser Extensions. Stay is available on Browser extension, iOS, macOS.
Overview
What Stay does
Stay is a userscript manager for Safari across iPhone, iPad and Mac, and its distinguishing feature is compatibility. It runs its own native scripts and also accepts scripts written for Tampermonkey and Violentmonkey, which addresses the real problem on Safari: almost every script worth having was written for a browser you are not using. What the scripts are for is the usual list, and the vendor's own examples are a fair summary of why people install one: automatic pagination so a paginated list loads continuously, immersive translation, redirect blocking, and aggregated search. Around the script manager sit features that are not script related at all, including bookmark sync that works across devices beyond the Apple ecosystem, a download manager with categorised folders, and a dark mode with detection for pages that do not offer one. The commercial model is unusual for this category and worth noting: a single one-time payment, reported at around $5, covering iPhone, iPad and Mac, with a free tier of limited functionality and no subscription. Against Tampermonkey's paid Safari build it is a different shape of purchase rather than a cheaper one, and against the free open-source Userscripts extension it is a paid product that does more.
What people use it for
- Running Tampermonkey scripts on Safari

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Stay.
- Apple only. No Chrome, Firefox or Edge build, so it cannot serve a cross-browser workflow.
- The free tier is deliberately limited, so the practical product is the paid one.
- Compatibility with Tampermonkey and Violentmonkey scripts is a translation layer rather than the real thing, and a script relying on an unusual GM function may not behave identically.
- It bundles bookmark sync, downloads and dark mode alongside the script manager, which is more surface area than some people want from an extension with access to every page.
- A much smaller project than the established managers, so fewer scripts are tested against it.
