Fixed price · per replica

Standard is priced for sustained load. Your chosen size sets the capacity available to each replica.

Scale across zones

Multi-DC placement is automatic once a process has 2+ replicas, at no extra charge.

App builds

Pay for the seconds your build runs

Dockerfile and Cloud Native Buildpacks builds use the same rate. Manual deploys, Git pushes, GitHub auto-deploys, and review-app builds all count.

€0.50 / hour

Limits: 16 vCPU · 30 GiB RAM

Billed by actual running seconds, including failed and canceled builds. A six-minute build costs €0.05. Queue time and image-only pipeline promotions have no build charge.

One balance, a clear stopping point

Before execution, Watasu holds up to €0.50 for at most one hour. A smaller available balance funds a shorter deadline. The build stops at its funded deadline, and unused funds return after it stops.

You need enough available balance for at least one second. No saved card or auto top-up is required. Card top-ups start at €5; there is no free monthly build allowance.

Common questions

Pricing, in plain language

Are app builds free?

Builds cost €0.50 per hour, billed by actual running seconds, with limits of 16 vCPU and 30 GiB RAM. Failed and canceled builds are charged for the time they ran. Queue time and image-only pipeline promotions have no build charge. There is no free monthly build allowance.

How much balance do I need to build?

Enough available balance for at least one second. Before execution, we reserve up to €0.50 for at most one hour, or fund a shorter deadline from your available balance. The build stops at that deadline; unused funds return after it stops. A saved card and auto top-up are optional. The minimum card top-up is €5.

Why prepaid?

You top up a balance, then your usage draws against it. That predictability on our side is a big part of why our prices are this low — and on your side, you can't get hit with a runaway bill.

What happens if my balance runs out?

You get warnings well before zero. If it does run out, your apps pause until you top up — they aren't deleted. New builds need enough available balance; a running build is covered only until its reserved deadline. No surprise bill shows up in your inbox.

Why EUR?

We're a European company billing in our home currency. The price you see on this page is the price your card gets charged — no FX layer in between.

Do you bill for bandwidth or egress?

No. Bandwidth is included with your plan, sized to match — normal app traffic at any tier isn't metered, shaped, or invoiced per GB. The only case where we'd reach out is genuinely abusive use (crypto mining, being part of a DDoS), and even then it's a conversation, not a surprise charge.

Can I run a serious app on the cheapest tier?

Yes. Standard 1× at €15/mo runs real production traffic at startup scale. Multi-DC kicks in once you scale to two replicas. For a mostly quiet process, Dynamic 1× stays reachable and bills measured CPU and memory instead.

What's the minimum top-up?

€5. Usage draws down your balance as it runs. A Hobby app costs €8 for a full month; €5 covers part of the month.
