DigitalOcean vs Hetzner vs Hostinger for AI side projects

If you are choosing between DigitalOcean vs Hetzner vs Hostinger for an AI side project, the wrong first move is comparing only the homepage number. This is a mixed, mostly source-backed guide built from current official provider pricing and docs plus HostFleet’s fresh provider notes. The sourced layer is what each provider actually charges, how backups and storage are billed, whether public IP is included, and whether billing stops when the server is powered off. The estimate layer is narrower: it decides which plan is the first honest always-on starting point for a small AI side project instead of the first plan that merely boots Linux.

The scope here is intentionally narrow. This article is about one always-on CPU box for work like:

• a small agent backend that mostly calls external APIs
• one API plus one worker with light persistence
• Open WebUI pointed at remote models
• a cron-heavy automation box
• one modest self-hosted AI tool or internal helper

It is not about local GPU inference, a browser fleet, or a serious multi-node production system. If you need the broader buyer guide first, start with Best hosting for AI agents on a budget. If you want the bigger 30-day budgeting context, read What it costs to run an AI side project on a VPS for 30 days. If you are already leaning toward Hostinger specifically, the deeper single-provider pass is Hostinger VPS for AI side projects.

The short answer

My practical verdict is simple: Hostinger wins the cheapest bundled always-on story, Hetzner wins the cheapest serious cloud baseline, and DigitalOcean wins only when you are willing to pay more for cleaner mainstream cloud ergonomics.

The comparison only makes sense if the assumptions are explicit

The floor numbers above assume:

• one server running all month
• one public IPv4 where the provider bills it separately
• weekly backup protection where the provider charges extra
• no extra block storage unless the base plan is unusable without it
• a CPU-only workload that mostly orchestrates external models rather than running them locally

That matters because every provider has a different trick in the pricing story:

• Hostinger makes the cheap number look better by bundling features and asking for prepaid commitment
• Hetzner makes the base server look cheaper by separating public IPv4 and backups from the instance
• DigitalOcean makes the entry number look cheap but reaches a more honest AI-side-project floor only after you move above the tiniest Droplets

1. Hostinger has the cheapest bundled floor, but the honest number is two numbers

Hostinger’s current VPS page lists:

• KVM 1: $6.49/month promo, $11.99/month renewal, 1 vCPU, 4 GB RAM, 50 GB NVMe, 4 TB bandwidth
• KVM 2: $8.99/month promo, $14.99/month renewal, 2 vCPU, 8 GB RAM, 100 GB NVMe, 8 TB bandwidth
• KVM 4: $12.99/month promo, $28.99/month renewal, 4 vCPU, 16 GB RAM, 200 GB NVMe, 16 TB bandwidth

The same page says all plans are paid upfront and include free weekly backups, snapshots, 1 Gbps networking, and a public API. Hostinger’s support docs also say VPS plans include a dedicated IP address and that resources are fixed by tier, so you cannot just add a little more RAM or disk without moving to the next full plan.

That makes Hostinger the cheapest bundled floor in this comparison. For one always-on box, the all-in story is easy to explain because the weekly backup and public IP are already in the plan:

• KVM 1 is the cheapest honest Hostinger floor for one light always-on worker or API box
• KVM 2 is the first tier I would call comfortable for one real small stack

The weakness is just as obvious:

• the promo number is not the steady-state number
• the billing model is prepaid rather than cloud-elastic
• if you outgrow the box, upgrades are coarse-grained
• moving regions later requires reinstalling the VPS, which Hostinger says deletes current data, backups, and snapshots unless you back them up yourself first

Hostinger does have one real AI-adjacent advantage beyond price. Its current Docker Catalog docs show an application catalog with AI-relevant tooling including Open WebUI, OpenClaw, Flowise, Langflow, LiteLLM, and Chroma. That does not turn Hostinger into a managed AI platform, but it does lower setup friction for buyers who want one cheap box and a friendlier deployment path.

2. Hetzner is still the cheapest serious cloud baseline once you add the missing pieces

Hetzner’s current Cloud pricing and docs still make it one of the strongest cheap self-hosted baselines in this market. The current Hetzner pricing data for NBG1 and HEL1 puts the cost-optimized anchors at:

• CX23: EUR 5.49/month, 2 vCPU, 4 GB RAM, 40 GB SSD
• CX33: EUR 8.49/month, 4 vCPU, 8 GB RAM, 80 GB SSD

The important catch is that the base server price is not the whole story. Hetzner’s billing FAQ and server docs say:

• public IPv4 is billed separately
• Primary IPv4 adds EUR 0.50/month
• backups cost 20% of the server price
• servers are billed hourly with a monthly cap
• powered-off servers still bill until they are deleted

That means the cheapest honest always-on floor is not EUR 5.49. It is closer to:

• CX23 + Primary IPv4 + backups = about EUR 7.09/month

That is still extremely aggressive for a real cloud VM with hourly billing. It also stays cleaner than many ultra-budget VPS offers because the economics are explicit instead of being hidden inside a long promo term.

Why Hetzner wins when it wins:

• it is the cheapest serious cloud-primitives answer here
• the billing model is flexible enough for tests and rebuilds
• firewalls are free
• EU traffic allowances are generous for this kind of side project

Why Hetzner loses when it loses:

• you are assembling the all-in floor from separate parts
• the cheapest line is shared-resource infrastructure, not a managed platform
• attached volume data is not covered by server backups, so the backup story gets more complicated if your side project grows beyond the base disk

If you want the cheapest honest cloud baseline for one small always-on AI side project, Hetzner remains the strongest answer in this set.

3. DigitalOcean has the cleanest mainstream cloud ergonomics, but not the cheapest honest floor

DigitalOcean’s current public Droplet pricing starts at:

• 512 MiB / 1 vCPU: $4/month
• 1 GiB / 1 vCPU: $6/month
• 2 GiB / 1 vCPU: $12/month

DigitalOcean’s docs also now say CPU Droplets are billed per second with a minimum charge of 60 seconds or $0.01, whichever is higher. That is a real improvement for short-lived testing. But the same docs say billing continues while a Droplet is powered off and stops only when the Droplet is destroyed.

The honest floor rises because the supporting costs are explicit:

• weekly backups cost 20% of the Droplet price
• additional outbound transfer is $0.01/GiB
• volumes cost $0.10/GiB-month whether or not they are attached
• snapshots cost $0.06/GB-month
• reserved IPv4 is free while assigned to a Droplet, but an unassigned reserved IPv4 costs $5/month

For this article’s workload shape, I would not treat the $4 or $6 Droplets as the first honest AI-side-project floor. They are legitimate products, but they are more honest as test boxes, tiny helpers, or dev environments than as the default home for one real always-on AI side project.

The first DigitalOcean tier I would treat as credible for this topic is:

• 2 GiB Basic Droplet at $12/month
• plus weekly backups at $2.40/month
• for an honest floor of $14.40/month

That is why DigitalOcean loses the cheapest-floor contest while still being a good product. What you are paying for is not raw specs. You are paying for a more familiar ecosystem, clearer docs, bundled monitoring and firewalls, and a mainstream cloud operating model that many teams already know how to live with.

The real decision is bundled cheap versus cloud cheap versus convenience cheap

The comparison gets clearer once you stop asking who is cheapest in absolute isolation.

Buy Hostinger if you want the lowest predictable always-on bill

Hostinger is the best fit if you want:

• one box you expect to keep running continuously
• bundled backups and public IP
• more RAM per dollar than the mainstream cloud options
• lower setup friction through Docker Catalog templates and a friendlier panel

It is weaker if you want clean month-to-month cloud-style experimentation or fine-grained scaling.

Buy Hetzner if you want the cheapest honest cloud baseline

Hetzner is the best fit if you want:

• the lowest serious all-in floor once you add the missing pieces honestly
• hourly billing with a monthly cap
• full control over a standard cloud VM without promo theatrics
• a stronger cloud-primitives baseline than typical bargain VPS marketing

It is weaker if you want a managed-feeling control plane or the simplest possible backup story.

Buy DigitalOcean if you want the easiest mainstream cloud story

DigitalOcean is the best fit if you want:

• clearer docs and more familiar cloud ergonomics
• straightforward firewalls, monitoring, and attached-volume workflows
• a platform your teammates are unlikely to find surprising
• per-second billing for throwaway tests, even if it is still not scale-to-zero

It is weaker if your main goal is squeezing the lowest monthly bill out of one always-on box.

The easiest mistake is comparing fake entry plans to honest starting points

This is where the estimate layer matters and needs to be stated plainly.

For a real AI side project, the first honest floor is usually not the smallest plan on the landing page. It is the first plan that can hold:

• one API or worker process
• logs and retries
• a reverse proxy or small helper service
• occasional memory spikes without turning every deploy into swap roulette

That changes the conversation:

• Hostinger KVM 1 is barely honest for one thin always-on service, while KVM 2 is the real value tier
• Hetzner CX23 is honest once IPv4 and backups are added, while CX33 is the safer floor for a small multi-service stack
• DigitalOcean 2 GiB is the first tier that feels like a serious baseline for this topic, even though smaller Droplets exist

If you want sizing guidance rather than billing guidance, the closer read is Best VPS setup for LangGraph or CrewAI. If you want the broader budget-VPS workload matrix, the companion piece is Hetzner vs Contabo vs Hostinger VPS for AI workloads.

FAQ

Which is actually cheapest for one always-on AI side project?

On current published pricing, Hostinger KVM 1 is the cheapest bundled floor. Hetzner CX23 plus IPv4 and backups is the cheapest honest cloud-primitives floor. DigitalOcean is not the cheapest once you move to the first more believable AI-side-project tier.

Is Hetzner cheaper than Hostinger?

Hetzner is cheaper in the cleaner cloud sense once you compare honest all-in floors without promo commitments. Hostinger is cheaper at the checkout page and bundles more into the plan, but the renewal and prepaid structure matter.

Why not use DigitalOcean’s $4 or $6 Droplets here?

Because this article is about the first honest always-on AI-side-project floor, not the first Droplet that exists. The $4 and $6 tiers are real, but they are better framed as tiny helpers, dev boxes, or very thin services than as the default home for a real small AI stack.

Which one is best for Open WebUI with remote models?

If the box is mostly hosting the UI and a little supporting infrastructure, Hostinger KVM 2 or Hetzner CX33 are the strongest value picks. DigitalOcean is easier to justify if the team values its ecosystem more than the price gap.

Which one is best for a small agent backend?

For the cheapest always-on answer, start with Hetzner CX23 or Hostinger KVM 1/KVM 2 depending on whether you value cloud-style billing or bundled plan simplicity. Choose DigitalOcean when operator convenience is worth paying extra for.

Final verdict

If I had to compress the market into one sentence, it would be this: Hostinger is the cheapest bundled box, Hetzner is the cheapest honest cloud box, and DigitalOcean is the expensive convenience pick.

The practical order is:

1. Choose Hostinger KVM 1 or KVM 2 if the mission is the lowest always-on bill and you are comfortable with prepaid VPS ownership.
2. Choose Hetzner CX23 or CX33 if you want the best price-to-control ratio in a standard cloud model.
3. Choose DigitalOcean 2 GiB or higher if you are willing to pay more for the easiest mainstream cloud ergonomics.

That is the most defensible way to compare DigitalOcean vs Hetzner vs Hostinger for AI side projects without pretending the smallest landing-page number is the same thing as an honest operating floor.
