It's a really common platform for vibe coded sites, as I understand it.

I used v0 for a vibe coded internal admin app.

*BUT* I downloaded the source code from Vercel’s site, built and deployed in a Docker container (I never download random npm packages to my local computer), deployed the Docker container to Lambda (choose your Docker deployment platform. They are a dime a dozen), had a tightly scoped IAM role attached to the Lambda and my secrets were in Secret Manager.

My deployment also had a placeholder for the secrets when it was deployed and they were never in my repo and purposefully had to be manually configured.

I would never trust something like Vercel for hosting. I’m not saying go all in on a major cloud provider. Get your own cheap VPS if that’s all you need and take responsibility for your own security posture the best you can.

First of all, it is often used in Korea.

Small startups often use it but typically outgrow it quickly unless they remain small and simple.
