With Vercel, I and my team can deploy our website automatically in minutes and that too free of cost. We use Next.js (React Framework) for our website and front-end and deploying them is the easiest task in our application development cycle. Not only this, we also have preview (staging) deployments setup because of Vercel. This could not have been possible for a small company like ours without Vercel.

We have not come across any big downsides of Vercel apart from one thing - Vercel cannot let other GitHub users see the deployment logs. It is only visible for the GitHub account with which Vercel is integrated. Review collected by and hosted on G2.com.
