I Don't care. There are tons of examples of building shit on stacks that won't be around. How about investing a shit ton of time into Azure Kubernetes using Docker containers to find out they dropped support, just like this startup can drop out and never be heard of again. Good luck with that.
This is a red herring. They don't have unique technologies. Just a very, very well done and accessible combination of best practices.
I have a bunch of apps on Vercel right now and zero worry that I will be able to deploy them somewhere else should they drop out for whatever reason. They are just Node/React apps.
that seems like the nature of tech stacks, going all the way back to Flash and Dreamweaver... at least with Vercel it's pretty agnostic — I can easily switch a node app from Vercel to Digital Ocean or whatever. Never used Docker before ha, tried to get into it but the install tutorial flow was completely broken :/
