Frequently Asked Questions
Why are developers leaving Heroku?
Teams are switching to open-source alternatives because of Free tier completely removed; idle demo dynos cost minimum $7-$14/month each. Postgres add-on pricing escalates sharply for modest storage. Dyno sleep times and cold starts harm side projects and proof-of-concepts. Closed dashboard and proprietary buildpack ecosystem. Open-source tools eliminate corporate telemetry and maintain full functionality offline.
Can I self-host these Heroku alternatives?
Yes, all recommended open-source equivalents support self-hosting on your own VPS or Kubernetes cluster via Docker Compose, Helm charts, or standalone binaries.
Are there user-seat limits or surprise bills?
No. Permissive open-source licenses (MIT, Apache 2.0, AGPL) have zero per-user seat pricing, allowing your entire engineering organization to collaborate with zero SaaS licensing fees.
