Honest EUR. No surprises.

Per-second EU-resident sandboxes, app hosting, and managed data — all on one prepaid balance. Top up, then run. No hidden egress invoices, no "contact sales" theater, no end-of-month surprises.

Sandboxes

Per-second, EU-resident compute for agents

Runtime is billed per second for the vCPU and memory you request — for agent evals and always-on production runs, hosted entirely in the EU. Stopped disks, checkpoints, and templates are prorated monthly.

Runtime — billed per second
vCPU €0.000010/vCPU·s
Memory €0.000002/GiB·s
Storage — per GiB, prorated monthly
Stopped sandbox disk €0.08/GiB·mo
Checkpoints €0.02/GiB·mo
Templates €0.02/GiB·mo

A sandbox with 2 vCPU and 1 GiB RAM costs about €0.08 per hour while it runs — a 90-second job costs a fifth of a cent. Stopped sandboxes keep their disk for instant resume and pay only for that storage. Read the sandbox billing docs.

App hosting

Run the rest of the product, per process

When you ship the app around the agent, each process type runs on its own pod size. Scale out (more replicas) and scale up (bigger pod) independently.

Plan Price
Hobby €5/mo
Standard 1× €10/mo
Standard 2× €20/mo
Standard 4× €40/mo
Standard 8× €80/mo
Standard 16× €160/mo

Multi-DC placement is on by default once you scale a process to 2+ replicas — at no extra charge.

Common questions

Pricing, in plain language

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. 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 €10/mo runs real production traffic at startup scale. Multi-DC kicks in once you scale to two replicas.

What's the minimum top-up?

€5 — enough to spin up a Hobby app and run it for a month, or to kick the tires on the platform before committing to more.

Pay less. Ship faster.
