A detailed feature-by-feature comparison of six major PaaS and deployment platforms: Vercel, Railway, Render, Fly.io, DigitalOcean App Platform, and Heroku. Covers deployment models (serverless vs long-running servers vs lightweight VMs), infrastructure ownership, scaling approaches (vertical/horizontal/auto), pricing models (usage-based vs instance-based), CI/CD capabilities, observability, networking, and developer experience. Key differentiators include Vercel's serverless-only model with cold starts and execution limits, Railway's usage-based pricing on owned hardware with automatic scaling, and the instance-based fixed pricing of Render, DigitalOcean, and Heroku. The guide ends with a Railway onboarding walkthrough.
