11 Best European Heroku Alternatives in 2026

Scaleway is Europe's sovereign cloud and AI provider, delivering 100+ products spanning compute, storage, networking, containers, databases, AI, and even quantum computing — all from four multi-AZ regions on European soil. Part of the iliad Group, it gives startups, enterprises, and public institutions a full-stack alternative to US hyperscalers without compromising on breadth, performance, or pricing transparency.

The platform covers every layer of the cloud stack: bare metal and elastic metal for dedicated performance, CPU and GPU instances (H100, L40S, L4) for AI training and inference, managed Kubernetes (Kapsule and multi-cloud Kosmos), serverless containers, functions and jobs, S3-compatible object storage, managed databases (PostgreSQL, MySQL, Redis, MongoDB), a ClickHouse-based data warehouse, Apache Kafka and Spark clusters, IoT Hub, transactional email, domain registration, and a full networking suite with VPC, load balancers, and WAF.

Key benefits:

• 5,000+ GPUs available on-demand for AI training, inference, and research workloads
• Managed Kubernetes with Kapsule (single-cloud) and Kosmos (multi-cloud) for portable orchestration
• Serverless platform covering containers, functions, jobs, and SQL databases with pay-per-use billing
• S3-compatible object storage plus block storage and Glacier cold archival at predictable pricing
• Generative APIs and AI inference to deploy and serve models without managing GPU infrastructure
• Transparent pricing at the product level with no hidden fees, egress surprises, or commitment traps
• Startup programs offering up to €36,000 in cloud credits for early and growth-stage companies
• Quantum as a Service — first European provider to offer managed quantum computing

Scaleway operates datacenters in France, the Netherlands, and Poland with upcoming regions in Sweden and Germany. Infrastructure is GDPR-compliant and HDS-certified for healthcare data hosting. The platform runs exclusively on renewable energy, publishes real-time Power Usage Effectiveness (PUE) metrics, and recycles hardware — making sovereignty and sustainability operational defaults rather than marketing claims.

Trusted by Mistral AI, Hugging Face, France TV, Photoroom, and the French Ministry of Education — the go-to European cloud for teams that need hyperscaler-grade infrastructure under European jurisdiction.

Hetzner Cloud is the cloud computing arm of Hetzner Online, one of Europe's largest data center operators, delivering high-performance infrastructure at a fraction of hyperscaler pricing since 1997. Founded in Gunzenhausen, Germany, Hetzner owns and operates every rack in its facilities — giving it full control over hardware, networking, and costs that translates directly into savings for customers.

The platform offers four server families to cover every workload profile: CX (cost-optimized Intel/AMD shared vCPU), CPX (regular-performance AMD EPYC shared), CAX (Arm64 Ampere Altra at the lowest price point), and CCX (dedicated AMD EPYC vCPU with zero noisy-neighbor risk). Alongside compute, the product catalog includes S3-compatible object storage, attachable block volumes on NVMe RAID10, managed Kubernetes (HKE) with a free control plane, load balancers, floating IPs, private networks, stateful firewalls, snapshots, DNS management, and one-click app deployments for Docker, Nextcloud, GitLab, and more.

Key benefits:

• 20 TB monthly traffic included in EU regions — 4–5x more than competitors, with no surprise egress bills
• Four server families (CX, CPX, CAX, CCX) from shared ARM instances at €3.99/mo to dedicated vCPU machines
• Managed Kubernetes (HKE) with free control plane, auto-scaling node groups, and integrated load balancers
• S3-compatible object storage built on Ceph with flat, predictable pricing and no per-operation fees
• Own-operated data centers in Nuremberg, Falkenstein, Helsinki, Ashburn, Hillsboro, and Singapore
• Full automation stack with REST API, CLI, Terraform provider, Ansible modules, and Kubernetes integrations
• NVMe local storage delivering 40k+ random IOPS and ~3 GB/s sequential throughput
• 100% renewable energy from hydropower since 2008, with PUE between 1.10–1.16 and zero water cooling

Hetzner's German and Finnish data centers hold ISO 27001 and BSI C5 certifications, and the company is EMAS-certified for environmental management. Infrastructure sits entirely outside the US CLOUD Act, making Hetzner a natural fit for teams that need GDPR-compliant hosting with genuine European data residency. Natural air cooling handles climate control for up to 98% of the year, waste heat warms office spaces, and servers average an 8-year lifecycle through refurbishment — reducing CO₂ emissions by 77,000 tonnes annually compared to standard grid power.

The go-to European cloud for developers, startups, and businesses that refuse to overpay — Hetzner proves that world-class infrastructure and transparent pricing are not mutually exclusive.

Clever Cloud is a French Platform-as-a-Service built entirely on infrastructure the company owns and operates in France. Push code via Git and Clever Cloud automatically detects the language, builds the app, deploys it with zero downtime, and handles scaling — supporting 15+ runtimes including Node.js, PHP, Python, Java, Go, Rust, Ruby, Scala, and .NET Core.

Managed add-ons cover the full stack: PostgreSQL, MySQL, MongoDB, Redis, Elasticsearch, Cassandra, and Pulsar, plus Cellar S3-compatible object storage. Built-in Grafana dashboards, centralised log management, and alerting provide full observability, while a Keycloak-based IAM handles access governance and audit trails.

Key benefits:

• 15+ language runtimes from Node.js and PHP to Go, Rust, Scala, and .NET Core
• Git-push deployment with automatic language detection and zero-downtime updates
• Managed databases — PostgreSQL, MySQL, MongoDB, Redis, and Elasticsearch
• Auto-scaling with 99.90% SLA standard and 99.99% on Premium
• S3-compatible object storage via Cellar with no egress fees within the platform
• Built-in Grafana observability — metrics, logs, and alerts without extra tooling
• ISO 27001 and HDS certified for healthcare data hosting on French infrastructure
• SecNumCloud available via Cloud Temple partnership for highest-sensitivity workloads

Clever Cloud operates its own datacenters in France with no data subcontracted to third-party clouds.

Scalingo lets developers deploy at lightning speed while keeping data sovereign in Europe. It is the first European Platform as a Service certified for Health Data Hosting (HDS) and ISO 27001, with datacenters located in France and a SecNumCloud region for regulated workloads that require the highest French government assurance level.

The platform supports git-based deployments, autoscaling triggered by metrics, zero-downtime rolling releases, managed databases with point-in-time recovery, and automatic failover for high availability. Encryption at rest and in transit is on by default, and managed vector databases such as pgvector and OpenSearch KNN make Scalingo a natural fit for AI-driven applications built on PostgreSQL and MongoDB.
