DigitalOcean vs Hetzner Cloud for AI side projects

If you are choosing between DigitalOcean vs Hetzner Cloud for AI side projects, the real decision is not just price. It is whether you want the lowest honest always-on cloud bill or the cleanest mainstream cloud operating experience.

This article is a mixed, mostly source-backed guide built from current official provider pricing and billing docs plus HostFleet’s current provider notes. The sourced layer is the current entry pricing, backup rules, traffic policy, IP charges, billing behavior, and storage caveats. The estimate layer is narrower and explicit: which plans are the first honest fit for a small AI side project instead of the first plans that merely boot Linux.

The scope is CPU-first on purpose. This is about workloads like:

• a small agent backend that mostly calls external model APIs
• one API plus one worker with light persistence
• LiteLLM, Open WebUI, or an internal AI tool on one box
• cron-heavy automation or webhook processing
• one modest self-hosted stack with a small database or queue

This is not a GPU inference guide, a browser-fleet benchmark, or a multi-node production architecture piece. If you need the broader market map first, read Best hosting for AI agents on a budget. If you are still deciding whether one VPS is even the right shape, pair this with What it costs to run an AI side project on a VPS for 30 days. If your real comparison includes promo-priced VPS bundles, the wider buyer guide is Hetzner vs Contabo vs Hostinger VPS for AI workloads.

The short answer

My practical verdict is simple: Hetzner wins when the mission is the lowest honest always-on cloud bill. DigitalOcean wins when you are willing to pay more for cleaner mainstream cloud operations and a clearer upgrade ladder.

Why this comparison matters more than the homepage number

A lot of cheap-hosting comparisons flatten these two providers into “both are just cloud VMs.” That misses the buyer decision.

Hetzner is the stronger answer when you want:

• the lowest monthly floor for one real cloud server
• hourly billing with a monthly cap
• generous EU traffic for CPU-first side projects
• full control and no platform tax

DigitalOcean is the stronger answer when you want:

• easier-to-explain product boundaries
• simpler public-IP assumptions
• very clear docs and billing behavior
• a cleaner path from basic shared CPU to higher-performance dedicated tiers

That is why the right question is not “which is cheaper?” It is “which operating model am I actually buying?“

1. Hetzner is still the cheapest honest cloud floor

Hetzner’s current cost-optimized cloud line remains one of the strongest low-cost CPU baselines in this market. The current official Hetzner pricing data for NBG1 and HEL1 plus HostFleet source notes put the most relevant entry tiers at:

• CX23: 2 vCPU, 4 GB RAM, 40 GB SSD at EUR 5.49/month
• CX33: 4 vCPU, 8 GB RAM, 80 GB SSD at EUR 8.49/month
• CAX11: 2 Ampere vCPU, 4 GB RAM, 40 GB SSD at EUR 5.99/month if your stack is already Arm-safe

The important correction is that the landing-page server number is not the honest operating floor. Hetzner’s billing docs also say:

• cloud servers do not include public IP addresses by default
• Primary IPv4 is billed separately at EUR 0.50/month
• Primary IPv6 is free
• backups cost 20% of the server price
• powered-off servers still bill until you delete them

That produces the first honest small-project math:

• CX23 + Primary IPv4 + backups: about EUR 7.09/month
• CX33 + Primary IPv4 + backups: about EUR 10.69/month

Those are still excellent numbers for a real cloud VM with hourly billing and no promo-prepay trick attached.

Where Hetzner wins

Hetzner is the better buy if your workload is mostly boring always-on orchestration:

• one agent backend that mostly calls external APIs
• one small API plus one worker
• one LiteLLM or Open WebUI support box
• one self-hosted internal AI tool with ordinary Linux ownership

Its traffic policy is also better than many buyers expect. Hetzner’s traffic docs currently show 20 TB included for EU CX, CPX, and CAX cloud servers, with overage at EUR 1/TB. For small AI-side-project traffic, that is generous.

Where Hetzner loses

Hetzner is cheap because it gives you infrastructure primitives, not platform ergonomics. That means:

• you assemble the all-in floor from server, IP, and backup pieces
• you own the Linux box, deployment flow, and persistence story yourself
• the cheapest shared lines are still cheap shared infrastructure, not magic

If what you really want is a cloud VM that another teammate can understand instantly without reading three docs pages, Hetzner is not the easiest answer even when it is the cheapest.

2. DigitalOcean is the cleaner cloud, not the cheaper one

DigitalOcean’s current Droplet pricing still starts at:

• 512 MiB / 1 vCPU / 10 GiB SSD / 500 GiB transfer: $4/month
• 1 GiB / 1 vCPU / 25 GiB SSD / 1,000 GiB transfer: $6/month
• 2 GiB / 1 vCPU / 50 GiB SSD / 2,000 GiB transfer: $12/month
• 4 GiB / 2 vCPU / 80 GiB SSD / 4,000 GiB transfer: $24/month

DigitalOcean’s docs also say CPU Droplets are billed per second with a minimum charge of 60 seconds or $0.01, whichever is higher. That is cleaner than old hourly billing, and it makes short-lived tests cheaper.

But DigitalOcean is still not a scale-to-zero product. The docs are explicit that:

• billing starts when you create the Droplet
• billing continues while the Droplet is powered off
• billing ends only when you destroy the Droplet

The honest DigitalOcean floor starts above the headline number

For AI side projects, I would not treat the $4 or $6 Droplets as the first honest baseline. They are real products, but they are more honest as:

• test boxes
• tiny helpers
• dev environments
• extremely thin single-service deployments

The first DigitalOcean tier I would recommend without apology for this article’s workload shape is:

• Basic 2 GiB / 1 vCPU at $12/month
• plus weekly backups at 20% = $2.40/month
• for an honest floor of $14.40/month

If the project is already a small multi-service system, the more honest shared-CPU starting point is:

• Basic 4 GiB / 2 vCPU at $24/month
• plus weekly backups at $4.80/month
• for an honest floor of $28.80/month

That is where DigitalOcean becomes easy to explain and hard to call cheap.

Where DigitalOcean wins

DigitalOcean is the better buy when you want a mainstream cloud that stays legible:

• public IPv4 is already part of the normal Droplet story
• monitoring and firewalls are included
• the product ladder is clear
• the docs are unusually good at telling you how billing and add-ons actually work

If I were putting a small AI backend in front of a teammate who does not enjoy cheap-cloud archaeology, DigitalOcean is the easier handoff.

3. Billing behavior matters more than buyers think

This is where the two providers are more similar than the marketing suggests.

Both bill until deletion

Hetzner and DigitalOcean both say powered-off servers still bill until you delete them. That means neither is a scale-to-zero answer.

Hetzner’s model:

• hourly billing with a monthly cap
• hourly usage rounded up
• powered-off servers still bill until deletion

DigitalOcean’s model:

• per-second billing with a 60-second or $0.01 minimum
• monthly cap
• powered-off Droplets still bill until destruction

The difference is not that one provider is elastic and the other is not. The difference is that DigitalOcean is slightly friendlier for short-lived tests, while Hetzner remains much cheaper for the same always-on box.

The IP story is cleaner on DigitalOcean

This is one of the most practical differences in the entire comparison.

DigitalOcean says each Droplet comes with its own public IPv4 address, while Hetzner bills Primary IPv4 separately from the server. That means:

• DigitalOcean’s entry price is closer to the everyday network story buyers expect
• Hetzner’s entry price needs one more mental step before it becomes the real monthly floor

This is a small operational detail that becomes a large buyer-experience difference.

4. Storage and backup caveats are important on both sides

Neither provider magically solves stateful self-hosting. The differences are in pricing clarity and in how painful the caveats are.

DigitalOcean storage is cleaner, but pricier

DigitalOcean’s docs say:

• volumes cost $0.10/GiB-month
• a volume can attach to only 1 Droplet at a time
• a single Droplet can attach up to 15 volumes
• volumes range from 1 GiB to 16 TiB
• volumes are not included in Droplet backups

That is operationally clean, but it pushes the real bill upward quickly.

Hetzner storage is cheaper, but the protection story is rougher

Hetzner’s volume docs and FAQs say:

• volumes scale from 10 GB to 10 TB
• volumes are billed hourly with a monthly cap
• volumes are triple-replicated across three physical servers
• a volume can attach to only 1 server at a time
• server backups and snapshots do not include attached volumes
• Hetzner does not provide snapshots or backups for volumes

That last point is the one buyers miss. Triple replication helps with hardware failure. It does not replace a backup strategy for your important application data.

The practical lesson

If the side project has meaningful state on attached volumes, neither provider should be treated as “backup solved.” DigitalOcean is easier to understand here. Hetzner is cheaper, but the volume-protection story is meaningfully harsher.

5. What I would actually buy

Buy Hetzner first if the mission is the cheapest honest always-on cloud box

Choose Hetzner if you want:

• the lowest real monthly floor for one Linux box
• enough RAM and CPU to run one API plus one worker cheaply
• generous EU traffic for the price
• hourly cloud billing without a prepaid contract

My default pick here is:

• CX23 for one thin always-on service
• CX33 if the project is already a real small stack

Buy DigitalOcean first if the team values cleaner cloud ergonomics

Choose DigitalOcean if you want:

• simpler public networking assumptions
• clearer docs and product boundaries
• easier mainstream cloud handoff to other humans
• a straightforward path from basic shared VMs to CPU-optimized or general-purpose tiers

My default pick here is:

• Basic 2 GiB for one light API or worker
• Basic 4 GiB for a real small stack
• CPU-Optimized 4 GiB / 2 vCPU only when shared CPU becomes the actual problem

FAQ

Is Hetzner cheaper than DigitalOcean for AI side projects?

Usually yes by a large margin on the entry always-on floor. A Hetzner CX23 with Primary IPv4 and backups is about EUR 7.09/month, while the first honest DigitalOcean floor in this article is $14.40/month on a 2 GiB Basic Droplet with weekly backups.

Why would anyone choose DigitalOcean then?

Because DigitalOcean is easier to operate, easier to explain, and easier to hand off. The product ladder, public-IP story, monitoring, firewalls, and docs are all cleaner than the cheapest-cloud baseline.

Is DigitalOcean’s $4 Droplet a real answer for AI hosting?

It is a real product, but not the first honest baseline for most AI side projects. It is better framed as a tiny helper, dev box, or very thin service than as the default home for a real always-on AI backend.

Is Hetzner better for bandwidth-heavy side projects?

Often yes, especially in EU regions. Hetzner’s current traffic docs show 20 TB included for EU CX, CPX, and CAX cloud servers, while DigitalOcean’s small Droplets start at 500 GiB and 1,000 GiB transfer and bill overage at $0.01/GiB.

Which one is better for Open WebUI with remote models?

If the box mostly hosts the UI and a little support infrastructure, Hetzner CX33 is the stronger value pick. DigitalOcean Basic 4 GiB is easier to justify if the team cares more about operating comfort than the bill.

Final verdict

If I had to compress the whole market into one sentence, it would be this: Hetzner is the cheap-cloud winner, while DigitalOcean is the clean-cloud winner.

The practical buying order is:

1. Start with Hetzner CX23 or CX33 if the main goal is the lowest honest always-on cloud bill.
2. Start with DigitalOcean Basic 2 GiB or 4 GiB if you are willing to pay more for easier mainstream cloud operations.
3. Move to DigitalOcean’s dedicated CPU families only when the workload genuinely needs more predictable local CPU and you want to stay inside the same provider.

That is the honest July 9, 2026 answer to DigitalOcean vs Hetzner Cloud for AI side projects without pretending price and operations are the same thing.
