Clever Cloud vs Heroku

Why Switch from Heroku to Clever Cloud?

Heroku set the template for modern application hosting. For European teams, the structural concerns are increasingly hard to ignore: Salesforce ownership since 2010, AWS-backed underneath, US legal jurisdiction. The 2025 ICC / Microsoft sovereignty incident made the abstract concerns concrete.

Clever Cloud is the French alternative, founded in Nantes in 2010. Container-based architecture, European data centres by default, native add-ons covering the common database and cache requirements, with strong adoption in the French government and regulated-industry deployments.

Pricing

As of October 2026, Clever Cloud’s pricing page lists no fixed plan prices:

• Free credits on sign-up, no payment card required
• Per-second billing for deployed resources, with auto-scaling limits you set so costs stay capped
• Price estimator on the website to calculate costs per product and zone
• Monthly invoice in EUR with itemised consumption

The EUR-native billing and EU VAT handling are operationally meaningful for European businesses.

Privacy & Data Sovereignty

Clever Cloud’s structural advantages:

• French corporate jurisdiction — Clever Cloud SAS subject to French and EU law
• European data centres by default — default zones in France; zones in London, Montreal, Singapore and Sydney are optional
• GDPR-native with Article 28 DPA
• HDS (Hébergeur de Données de Santé) certified for healthcare workloads
• No US parent company; default zones run on European providers (OVHcloud, Scaleway, Ionos, Cloud Temple). Oracle Cloud is also an infrastructure partner, so check which provider backs the zone you pick
• Strong NIS2 alignment for essential-entity deployments

Example Scenarios

Illustrative scenarios of how teams typically use these tools — not documented customer case studies.

A French regional authority can run a citizen-services platform on Clever Cloud, combining French jurisdiction, HDS-certified zones (for health-related services) and developer-friendly deployment to meet public procurement requirements.

A European fintech startup leaving Heroku can move customer data to French zones to simplify conversations with its financial regulator about US-cloud hosting. A moderate app can typically be migrated over a weekend.

An e-commerce company in Germany can use Clever Cloud for European customer-facing workloads that require EU data residency, while keeping Heroku for US-market workloads — a sovereignty-aware split-stack approach.

Company Background

Clever Cloud SAS was founded in 2010 in Nantes, France, with Quentin Adam among its co-founders. The company pioneered French PaaS at a time when most European developers defaulted to Heroku. Clever Cloud has remained French-owned and operated, with engineering primarily in Nantes.

By 2026, Clever Cloud serves thousands of customers across French and European markets, including significant French government deployments, mid-sized European enterprises, and individual developers. Its team counts 90+ people, headquartered in Nantes with offices in Paris, Lille, Lyon and Brest.

Clever Cloud has been actively engaged in French sovereign-cloud initiatives and DINUM (interministerial digital service) collaborations.

Who Should Switch?

Clever Cloud is ideal for:

• Anyone preferring Docker-first PaaS over pure buildpack approaches

The Bottom Line

Heroku remains valid for teams deeply embedded in the Salesforce ecosystem or needing a broad global region footprint. For European application hosting, Clever Cloud is the structurally better choice — particularly for French and DACH deployments, regulated industries, and any team that values Docker-first flexibility over rigid buildpack patterns.

Frequently Asked Questions

How does Clever Cloud compare to Scalingo?

Both are French PaaS alternatives to Heroku. Clever Cloud is more container-oriented and has stronger integration with low-level infrastructure customisation (custom Docker images, advanced networking). Scalingo is more strictly Heroku-compatible at the buildpack level. For most apps, either works; for teams wanting deeper control, Clever Cloud often wins; for teams wanting pure Heroku migration, Scalingo is often the simpler path.

Where is data hosted?

Clever Cloud's default zones are in France (Paris, Roubaix), including HDS-certified zones for health data. Its zone list also includes Warsaw and zones outside the EU (London, Montreal, Singapore, Sydney), so check the zone you deploy to. Infrastructure partners include OVHcloud, Scaleway, Ionos and Cloud Temple, but also Oracle Cloud, a US provider. Clever Cloud SAS is a French company with no US parent, subject to French and EU law.

Is Clever Cloud SecNumCloud-qualified?

Clever Cloud offers SecNumCloud-aligned deployments through partnerships with qualified underlying infrastructure providers. The company itself is positioned as a managed PaaS layer; the underlying infrastructure provider determines the specific certification. For HDS (healthcare data), Clever Cloud has direct certification.

Can I migrate from Heroku?

Yes. Standard process: 1) Create Clever Cloud account and app, 2) Set environment variables, 3) Push git remote, 4) Migrate database, 5) Update DNS. Most Ruby, Node, Python, Go, PHP, Java, Elixir, and Scala apps move within 2-8 hours with minimal code changes.

What about pricing?

As of October 2026 Clever Cloud does not publish a fixed price list: resources are billed per second, and you estimate costs with the online price estimator for the products and zone you choose. New accounts get free credits to try the platform, with no payment card required. Invoices are in EUR with EU VAT handling.
