A comparison of three popular PaaS providers for deploying small Ruby apps: Heroku, Fly.io, and Render. Each is evaluated on always-on instances with 500MB RAM, shared CPU, and cheapest available database. Heroku is the most familiar but priciest and entering a sustaining engineering mode. Fly.io is the cheapest option (~$6.15/month for one app) with Docker-based deployment and fine-grained scaling, but has more complex configuration. Render sits between the two, offering Heroku-like simplicity with Docker support but limited basic database storage. Pricing breakdowns are provided for 1 and 3 apps.
