Which Should You Choose?

Choose Bun if:

  • •You need a faster JavaScript runtime for building applications
  • •You want better performance and tooling than Node.js at no extra cost
  • •You are making a runtime choice, not a deployment platform choice

Choose Heroku if:

  • •You need a PaaS for easy app deployment with git-push and managed Postgres
  • •You want zero infrastructure management for your web application
  • •You are choosing a deployment platform, not a runtime

Heroku is a PaaS deployment platform; Bun is a runtime. Heroku supports Bun via custom buildpacks or Docker. Heroku plans start at $5/month per dyno. Bun is free. You can run Bun on Heroku - they are not alternatives. If deployment ease is your priority, Heroku (or a cheaper alternative like Railway) is the tool. If raw performance is the concern, Bun is the runtime.
