Hetzner is the most popular server provider in the Odoo community for self-hosted deployments, and for good reason: it offers some of the cheapest bare-metal and cloud servers in Europe with enterprise-grade reliability. In 2026, Hetzner's CAX ARM instances deliver exceptional Odoo performance at prices that are difficult to match anywhere else. This guide covers everything you need to deploy Odoo on Hetzner — from picking the right server tier to configuring backups and connecting your server to a managed platform.
Why Hetzner for Odoo?
Hetzner has built a strong reputation in the European hosting community for transparent pricing, powerful hardware, and no hidden fees. Unlike AWS or GCP, what you see in the Hetzner pricing table is what you pay — including generous traffic allowances. For Odoo deployments specifically, three factors make Hetzner stand out:
- Price-to-performance: Hetzner's CAX ARM servers deliver multi-core performance at a fraction of competitors' costs
- EU data centers: Nuremberg, Falkenstein, and Helsinki — all within the EU/EEA for GDPR compliance
- Storage Boxes: Dedicated backup storage with SFTP/rsync/SMB access, separate from your server's disk
Understanding Hetzner's Server Tiers
Hetzner offers several cloud server types, and choosing the right one for Odoo matters more than you might expect.
| Series | CPU Type | Best For | Example (4 vCPU, 8GB) |
|---|---|---|---|
| CX (Shared AMD) | AMD EPYC (shared) | Dev, light production | CX32: ~€5.77/mo |
| CPX (Dedicated AMD) | AMD EPYC (dedicated) | Production workloads | CPX31: ~€15.19/mo |
| CAX (ARM64) | Ampere Altra ARM | Best overall value | CAX31: ~€9.89/mo |
| CCX (Dedicated x86) | AMD EPYC (dedicated) | High-traffic production | CCX23: ~€37.49/mo |
The CAX ARM Servers: Why They Are the Best Choice for Odoo
Hetzner's CAX series runs on Ampere Altra ARM64 processors and delivers outstanding multi-threaded performance. Python — the language Odoo runs on — performs well on ARM64 with modern builds. Odoo 16 and above ship with ARM64-compatible Docker images, making CAX servers a first-class deployment target.
The CAX11 (2 vCPU, 4GB RAM, 40GB SSD) costs approximately €3.79/month and is the most popular entry-level choice in the Odoo community. It comfortably handles 5–15 concurrent users and can serve as both the application and database server for small deployments. The CAX21 (4 vCPU, 8GB RAM, 80GB SSD) at ~€7.49/month is the go-to for 15–40 user environments.
One important note: ensure you use Docker images tagged for linux/arm64 or linux/amd64,linux/arm64. Official Odoo Docker images support ARM64 from version 16 onwards. For Odoo 14–15 on CAX servers, you may need to build your own ARM64-compatible image or use a CPX (x86) server instead.
Hetzner Pricing Comparison by Use Case
| Use Case | Recommended Server | Specs | Monthly Price | Concurrent Users |
|---|---|---|---|---|
| Development / Demo | CAX11 | 2 vCPU ARM, 4GB RAM, 40GB | ~€3.79/mo | 1–5 |
| Small Production | CAX21 | 4 vCPU ARM, 8GB RAM, 80GB | ~€7.49/mo | 10–25 |
| Medium Production | CAX31 | 8 vCPU ARM, 16GB RAM, 160GB | ~€15.49/mo | 25–60 |
| Large Production | CCX33 | 8 vCPU x86 dedicated, 32GB RAM | ~€68.99/mo | 60–150+ |
| Enterprise | Robot Dedicated | 32+ cores, 128GB+ RAM | From €50/mo | 150+ |
GDPR and EU Data Compliance with Hetzner
Hetzner operates three data center campuses: Nuremberg and Falkenstein (both in Germany) and Helsinki (Finland). All three are within the EU and covered by GDPR. Hetzner is a German company subject to German data protection law, which is among the strictest in the EU. For European businesses processing personal data in Odoo, Hetzner provides the contractual framework (DPA) needed for GDPR compliance. This is one of the primary reasons Hetzner dominates European Odoo community deployments.
Hetzner Storage Box for Odoo Backups
Hetzner offers Storage Boxes — dedicated backup storage volumes accessible via SFTP, rsync, SMB, and restic. These are separate from your server and persist independently, making them ideal for off-site Odoo backups. Storage Box pricing starts at €3.81/month for 1TB, making it extremely cost-effective compared to object storage alternatives.
For automated Odoo database and filestore backups, you can configure a daily rsync job to a Storage Box, or use restic for encrypted, deduplicated snapshots. DeployMonkey's S3 backup integration also works with Storage Boxes via the S3-compatible endpoint Hetzner provides on its Object Storage product (separate from Storage Boxes).
The Easy Way: Deploy Odoo on Hetzner with DeployMonkey
DeployMonkey's BYOS model works seamlessly with Hetzner Cloud servers. The process takes under ten minutes from a fresh server to a running Odoo instance with SSL:
- Create a Hetzner Cloud server: Log into the Hetzner Cloud console at console.hetzner.cloud, create a new project, and spin up a CAX21 or CX32 running Ubuntu 22.04. Add your SSH public key during server creation. Note the server's public IP.
- Connect to DeployMonkey: In your DeployMonkey dashboard, add the server under Servers → Add Server. Paste the IP and your SSH key or password. The platform verifies the connection and installs Docker automatically.
- Deploy Odoo: Create a new instance, pick your Odoo version (14–19), Community or Enterprise, and enter your domain. DeployMonkey provisions the full stack including Nginx, SSL via Let's Encrypt, and automated backups.
The free DeployMonkey plan covers one server and one instance, making the Hetzner CAX11 + DeployMonkey Free combination a fully managed Odoo deployment for approximately €4/month in server costs.
The Manual Way: Deploying Odoo on Hetzner with Docker
For those who prefer manual control, the process on Hetzner is identical to any Ubuntu 22.04 server. SSH into your new server and run:
Install Docker
apt update && apt upgrade -y
apt install -y docker.io docker-compose-plugin
systemctl enable --now dockerCreate a Docker Compose configuration
mkdir -p /opt/odoo && cd /opt/odooCreate a docker-compose.yml with the Odoo and PostgreSQL services, then bring the stack up with docker compose up -d. Configure Nginx as a reverse proxy on ports 80 and 443, and obtain an SSL certificate with Certbot. For the full recommended configuration, see our Odoo server requirements guide which includes production Odoo config file settings for workers and memory limits.
Hetzner Robot: Dedicated Servers for Large Deployments
For large Odoo deployments with 100+ concurrent users, Hetzner's Robot marketplace offers ex-leased dedicated servers at remarkably low prices. A former enterprise server with 32 cores and 128GB RAM often sells for €50–€80/month. These are physical machines in Hetzner's data centers that you manage entirely yourself. While they require more sysadmin work, they deliver performance that no cloud VM can match at the price point. DeployMonkey's BYOS model works equally well with dedicated servers — as long as you have SSH access, the platform can manage Odoo on it.
Hetzner vs DigitalOcean for Odoo
Both are excellent providers. Hetzner wins on price — especially for European users — and the CAX ARM series has no real equivalent in DigitalOcean's lineup at the same price point. DigitalOcean wins on UX (cleaner dashboard, better documentation for beginners) and on the availability of Managed PostgreSQL and other managed services. For pure Odoo hosting where you want maximum value per euro, Hetzner is the stronger choice. For beginners who value a polished control panel and US-based data centers, DigitalOcean may be preferable. See our DigitalOcean Odoo guide for a direct comparison.
