Why it stands out
Compare Render or Railway for modern usage-based alternatives; compare Fly.io when multi-region VMs beat dyno routing.

Tool profile
Classic git-push PaaS on dynos with add-ons for Postgres, Redis, and logging—still relevant for teams prioritizing DX over infra novelty.
Ruby, Node, Python, and Java services with minimal YAML
Heroku defined PaaS for a generation: connect GitHub, push main, get HTTPS and logs. Salesforce ownership shifted positioning toward enterprise and compliance, while competitors copied the model. It remains viable when you want managed runtime patching and a marketplace of add-ons without Kubernetes. Not the cheapest raw compute—buy it for speed and predictability of operations.
