No licensing issues as it is MIT lisenced **What do you dislike about Spin.Js?** Although it is easy to use and there are good functionalites, the design looks old when used along side modern CSS frameworks. **What problems is Spin.Js solving and how is that benefiting you?** We wanted quick and easy way to implement spinner to our legecy websites and Spin JS came in handy due to its ease of use. ### 2. Old Spinner for Loading Websites **Rating:** 3.0/5.0 stars **Reviewed by:** Amit K. | Full Stack Engineer, Enterprise (> 1000 emp.) **Reviewed Date:** January 23, 2023 **What do you like best about Spin.Js?** Spin JS is a dynamic loader for all the website loads; during my time at one of my previous organisations, we used this, and it helped improve the CAQ Ration by 22%, but it was way back in 2019. **What do you dislike about Spin.Js?** As per the current user interface trends in the industry, where we have unique designs like Material UI and other open-source UI, the spinner looks dull, reducing the usability factor. **What problems is Spin.Js solving and how is that benefiting you?** We had a CMS site that had a lot of info to process, and since it was not optimised, there were a lot of customers dropping by in like 30 seconds after coming to the site; optimisation would have taken a long time and that's when we had a quick way of getting things started and retain customers, it helped us maintain customers by 25% since we were showing loading bar improving the usability factors. ### 3. The dynamic JS spinner for your loading activity indicator **Rating:** 3.0/5.0 stars **Reviewed by:** Claudio T. | Owner, Information Technology and Services, Small-Business (50 or fewer emp.) **Reviewed Date:** November 14, 2018 **What do you like best about Spin.Js?** I was there when the world of web development was taken by storm by the (re)discovery of the superpowers of XMLHttpRequest(), and already had a few years of experience under my belt.So I remember well we were missing a way of indicating that an Ajax request was being performed; soon after that came websites that allowed you to download a plethora of GIF and PNG spinners of varying size and (usually low) quality. Spin.js is the highly polished stepchild of those early attempts, and provides a neat ES6 JS script that can generate a spinner from a number of parameters. If you are the rare kind of developer who needs exactly this kind of indicator, there's nothing better that Spin.js. **What do you dislike about Spin.Js?** Well, most CSS frameworks nowadays provide built-in spinners of various kinds, so using an highly specialised, parametrised script like this can be viewed as a sort of overkill, given that nobody will really care about the length and radius of your loading indicators. **Recommendations to others considering Spin.Js:** Well, if you need this exact kind of spinner and/or you are of the maniacal type who needs to micromanage every single aspect of what you are creating, then go for it; else you may be good to go with the brea dand butter spinners provided by your CSS framework of choice or copy/paste SVG animations from the interwebs or whatever. **What problems is Spin.Js solving and how is that benefiting you?** Actually I used Spin.js only once, for fun, on a side project where I wanted to have a really huge loading indicator to elicit surprise in my user, and since this script uses scalable graphics that are always crisp and well defined, it allowed me to generate a larger-than-life spinner that occupied almost the entire screen. ## Spin.Js Discussions - [What is Spin.Js used for?](https://www.g2.com/discussions/what-is-spin-js-used-for) - [View Spin.Js pricing details and edition comparison](https://www.g2.com/products/spin-js/reviews?section=pricing&secure%5Bexpires_at%5D=2026-07-03+09%3A23%3A18+-0500&secure%5Bsession_id%5D=58e784dd-a1bb-4682-9dd3-23e2f6d61cab&secure%5Btoken%5D=d80266758fa46ad48dbd259d2869c1c58b4b21e6804cc6d83e2cae6cc88d1fa4&format=llm_user) ## Spin.Js Features **JavaScript Frameworks** - Libraries - Community - Widgets - Browser Support - Graphical Visualization - Mobile Support ## Top Spin.Js Alternatives - [Essential Studio](https://www.g2.com/products/essential-studio/reviews) - 4.5/5.0 (735 reviews) - [Progress Kendo UI](https://www.g2.com/products/progress-kendo-ui/reviews) - 4.4/5.0 (250 reviews) - [Angular](https://www.g2.com/products/angular/reviews) - 4.5/5.0 (156 reviews)
