Comparison

HostStack vs Heroku

The git-push workflow Heroku invented — on modern Docker runtimes, with EU data residency, at a quarter of the invoice.

Why developers choose HostStack

€5/mo Starter includes three services + a managed database + queue + search; Heroku's comparable bundle (Eco dynos + Mini Postgres + Mini Redis) lands around $20/mo and grows fast

Modern Docker runtime — bring any base image, runtime version, or system dependency. No buildpack incompatibility surprises during framework upgrades

Real EU data residency in Nuremberg or Helsinki with a DPA at signup. Heroku Common Runtime EU is limited to Ireland and ships through Salesforce / AWS

No 30-second request timeout. Long-running connections, websockets, and AI workloads work without dyno restart workarounds

TypeScript SDK and Terraform provider — first-party, not community-maintained

Managed MySQL, MariaDB, and MongoDB out of the box (Heroku ships PostgreSQL only; everything else is third-party add-on)

When NOT to choose HostStack

Heroku is the better fit in some cases. Here's when we'd tell you so.

You depend on a specific Heroku add-on with no Docker equivalent. Most are replaceable, but if you rely on add-ons like New Relic Heroku-tier, Memcachier, or Heroku Scheduler's exact UI you'll need to swap to the standalone vendor.

You're happy paying Heroku for the SOC 2 Type 2 / HIPAA / PCI Shield runtime. Our compliance roadmap is solid but we don't carry every certification yet.

You're running on Heroku Private Spaces with VPC peering to AWS. Our private networking is service-to-service inside HostStack; we don't peer to external VPCs.

You want zero-config Buildpack autodetection for an obscure runtime. We support Docker + framework presets; rare buildpacks need a Dockerfile.

Migrate from Heroku

Open a HostStack account

Containerize your Heroku app

If you don't already have a Dockerfile, our framework presets cover Node.js, Python, Ruby, Go, Java, PHP, .NET, and Elixir. Most heroku.yml services convert in one commit.

Carry over services and env vars

Export Heroku config vars (heroku config -s --app=APP) and push them with hoststack env bulk svc_… KEY1=VAL1 KEY2=VAL2 …. Procfile commands map directly to start commands.

Move the database

Provision a managed PostgreSQL on HostStack and stream a pg_dump from Heroku Postgres directly into it. Comparing Postgres options across providers? See our managed PostgreSQL Europe 2026 buyer's guide.

Flip DNS and decommission

Update your CNAME, wait for TLS to provision (usually seconds), rotate any Heroku-issued credentials, then delete the Heroku app. We have a clean cutover checklist in the docs.
