Scalingo is the platform I point people to when the requirement is literally "the data must live in France." It's a French PaaS with a Heroku-shaped workflow — git push, buildpacks, managed databases (PostgreSQL, MySQL, MongoDB, Redis and more), one-click scaling — hosted on French infrastructure, with certifications that matter in regulated industries, including health-data hosting. Their [documentation](https://doc.scalingo.com/) is straightforward and their support has a reputation for being actual humans who answer.
That focus is also the reason people outgrow it. The reasons I hear most often:
- Geography. Scalingo's regions are in France. That's the entire point for its core audience, but if your users are in North America or Asia, you're paying the latency tax on every request. Their [region docs](https://doc.scalingo.com/platform/internals/regions) spell out what's available.
- Workflow shape. It's buildpack-first, Heroku-style. That's wonderful until your app doesn't fit a buildpack cleanly and you start fighting the abstraction instead of using it.
- Ecosystem size. It's a focused company with a focused product. The integration catalog, community answers, and third-party tooling are all thinner than what surrounds the big US platforms.
If none of those bite you, stay — sincerely. Sovereignty plus simplicity is a rare combination. If one of them does, here are six alternatives worth evaluating.
1. PandaStack
Full disclosure: [PandaStack](https://pandastack.io) is our platform. What it shares with Scalingo is the shape of the workflow — connect a Git repo, push, and it builds and goes live, with managed databases (PostgreSQL, MySQL, MongoDB, Redis) attached to apps and DATABASE_URL injected automatically. What it adds on top is breadth: container apps, static sites, edge functions, and cronjobs all live in one dashboard, with live build logs, rollbacks, deployment history, and custom domains with automatic SSL.
Unlike buildpack-only platforms, you're not boxed in: PandaStack auto-detects frameworks and build commands for common stacks (Node.js, Python, Go and more), and if your app doesn't fit that mold, it builds any Dockerfile — using rootless BuildKit in ephemeral Kubernetes Job pods rather than a shared Docker daemon. Free-tier workloads run sandboxed in gVisor.
Pricing is flat and small: Free at $0 (5 web services, 5 static sites, 1 database, 100 GB bandwidth, 300 build minutes/month), Pro at $15/mo, Premium at $25/mo, plus per-hour compute tiers for larger workloads.
The honest caveats: infrastructure runs on Google Cloud in the US (us-central1), so if French data residency is your legal requirement, PandaStack is not your answer — Scalingo or Clever Cloud is. It's also a younger platform, and free-tier apps scale to zero when idle, which means cold starts on hobby projects.
Best for: developers who liked Scalingo's simplicity but want Docker flexibility, more product surface (static sites, functions, cron), and flat pricing — and don't need EU residency.
2. Clever Cloud
The most natural like-for-like swap. [Clever Cloud](https://www.clever-cloud.com/) is also French, also sovereignty-minded, also Git-push-driven, with a broad runtime matrix and managed databases. If your reason for leaving Scalingo is product fit rather than geography — you want different runtimes, a different scaling model (Clever Cloud does vertical + horizontal auto-scaling), or just a second French vendor for procurement reasons — this is the first door to knock on.
It's usage-based rather than fixed dyno-style pricing, which can work for or against you depending on traffic shape. The developer experience is more utilitarian than the polished US platforms, and like Scalingo, the surrounding ecosystem is smaller.
Best for: teams that need to stay French/European and want a Scalingo peer with a broader runtime and scaling story.
3. Render
[Render](https://render.com/) is the mainstream modern PaaS: web services, workers, cron jobs, managed Postgres, preview environments, and render.yaml blueprints for infrastructure-as-code. It supports both native builds and Dockerfiles, the documentation is genuinely good, and the platform has enough adoption that most problems you hit have a written answer somewhere.
It has a free tier with the usual constraint — free web services spin down after inactivity and take a moment to wake. Regions cover the US, Europe, and Asia-Pacific; European data residency exists at the region level ([details](https://render.com/docs/regions)), but it's an American company, which matters for some sovereignty interpretations and not others — ask your DPO, not me.
Best for: teams that want the safest general-purpose choice with mature docs and a large community.
4. Fly.io
[Fly.io](https://fly.io/) answers the geography problem from the opposite direction: instead of one sovereign region, it gives you dozens of regions globally and runs your containers as Firecracker microVMs close to users. You get scale-to-zero machines, volumes, private networking, and more low-level control than any traditional PaaS.
The cost of that control is that Fly is more IaaS-flavored than Scalingo ever was. The database story in particular requires attention — their Postgres offerings have historically involved more operational ownership than a fully managed service, and their [docs](https://fly.io/docs/postgres/) are upfront about it. Billing is pay-as-you-go.
Best for: globally distributed apps where per-region latency is the actual problem you're solving.
5. Railway
[Railway](https://railway.com/) is the fastest of the group from repo to running service. Nixpacks-based detection (or your Dockerfile), databases added in a click, and an unusually good environment-variable system where services reference each other's credentials directly. It feels like a tool built by people who deploy a lot of side projects — in a good way.
Billing is usage-based on actual resource consumption ([pricing docs](https://docs.railway.com/reference/pricing)), which is efficient for small or bursty workloads but makes budgeting less deterministic than Scalingo's per-container sizing. It's a US platform, region coverage is narrower than Render or Fly, and there's no meaningful sovereignty story.
Best for: prototypes, internal tools, and small products where iteration speed beats everything else.
6. Heroku
The original, and still relevant. [Heroku](https://www.heroku.com/) has the deepest buildpack ecosystem, the most mature add-on marketplace, and workflow features — pipelines, review apps, release phases — that the industry has been copying for a decade. If your Scalingo app is buildpack-shaped, it will feel immediately at home; the two platforms share a workflow lineage.
The caveats are well known: Heroku removed its free tier in 2022, dyno pricing is on the premium end for what you get, and the platform's pace of innovation slowed for years under Salesforce (though investment has picked up again). EU region support exists on common runtime, but data residency guarantees require their enterprise-tier offerings.
Best for: teams that want maximum ecosystem maturity and are willing to pay for it.
Quick comparison
| Platform | Region story | Free tier | Model |
|---|---|---|---|
| PandaStack | US (GCP us-central1) | Yes — 5 apps, 5 sites, 1 DB | Flat $0/$15/$25 + usage compute |
| Clever Cloud | France/EU | Trial | Usage-based |
| Render | US/EU/APAC | Yes (spins down) | Per-service plans |
| Fly.io | Global, dozens of regions | No | Pay-as-you-go |
| Railway | US-centric | Trial credit | Usage-based |
| Heroku | US + EU | No (removed 2022) | Per-dyno plans |
Choosing
The decision tree is shorter than it looks. Legally bound to France? Clever Cloud, or stay on Scalingo. Global users? Fly.io. Want the most-trodden path? Render or Heroku. Want the Scalingo feeling — push and it runs, database wired in — with Docker freedom and a flat bill? That's the gap we built PandaStack for; you can see if it fits at [pandastack.io](https://pandastack.io).
