Render is a cloud application platform founded 2018, positioned as "modern Heroku". Like Railway, captured Heroku decline tailwinds (2022 Heroku killing free tier caused massive user migration). Render differentiators: (1) Generous free tier (static sites fully unlimited free, web service 750 hours/month free — equivalent to one always-on service); (2) Heroku-style deployment experience but cheaper pricing; (3) Simple dashboard UI suits developers not wanting AWS complexity. Function coverage: web service (Node / Python / Ruby / Go / custom Docker), static site (frontend), cron jobs, background workers, Postgres, Redis, private services. vs. Railway: Render free tier more generous, Railway UX smoother (usage-based vs. Render fixed tiers). Both mainstream Heroku alternative options.
