One thing I like about Filestack is that it saves you from doing a lot of extra work. Handling file uploads sounds simple when you first start building an application, but it gets complicated when you have to support different file formats, image sizes, and upload methods.

I particularly like the File Picker. It gives you a ready-to-use upload option, so you don't have to spend time building the entire thing yourself. The image editing options are also useful. You can resize, crop, and convert images by simply changing a few things in the URL. This comes in handy when you need the same image in different sizes across your application.

Another good thing is that you get uploading, image processing, and file delivery in one place. You don't have to manage different services for everything. The CDN also helps with delivering files.

For developers working on web applications, dashboards, or platforms where users regularly upload images and documents, Filestack can save quite a bit of time. Review collected by and hosted on G2.com.

The first thing I would consider is the pricing. It is important to understand how the usage is calculated before choosing a plan. Uploads are not the only thing you need to consider. Storage, bandwidth, and image transformations also add to your usage.

This might not be a big concern when you're working on a small project, but things can get expensive as the number of users and uploaded files increases. So, I would suggest checking the pricing properly before using it for a large application.

Some security settings also need a little extra attention. If you want to control who can upload or access files, you need to configure the available settings properly. It takes some time to get everything set up the way you want. Review collected by and hosted on G2.com.
