A friend used Replit to prove out a startup (it worked) and what worked for him is that Replit has a whole platform integrated with their coding assistant that include hosting and backend runtimes. So his cycle time of vibe-deploy-test was very short and very simple for someone non-technical.
No need to think about how/where to deploy, cloud platforms (AWS, GCP, Azure), etc. Just vibe and deploy.
(He did end up moving off the platform once he had enough validation)
