Heroku CLI

v11.3.0 — official command-line interface for managing Heroku applications and services. Built with oclif and Node.js, it supports app deployment, scaling, monitoring, Postgres databases, CI/CD pipelines, add-ons, SSL certificates, domains, team collaboration, Private Spaces, logs, and a plugin ecosystem. v11 is a major rewrite: ESM-only (converted from CJS), oclif v4, single package (monorepo removed), new color system (ansis replaces chalk), Node >=20 required. Ships TypeScript types. Active development with frequent releases.
