| Free tier | Claim $5 in free credit - one-time, per account, and nothing is charged for it. Signing up is free and takes no payment details. unit mixed; metered on wall-clock; credit, not hours: USD 5 of prepaid balance |
|---|---|
| Price | none stated |
| Per-object cap | not applicable |
| Retention | Power off a Cube and its disk is kept exactly as you left it; only the disk keeps billing, at USD 0.00005/GB/hour on the full provisioned size. |
| Egress | Unmetered. Krova does not bill per gigabyte and sets no monthly transfer allowance; the network is shared and sustained heavy traffic can be rate-limited. Outbound TCP 25 is blocked. free_allowance: unmetered |
| Identity | email Email link or 6-digit code, or Google; 'No credit card to sign up'. The USD 5 credit is granted at account activation with nothing charged, and the Welcome tier unlocks with it, so a card is needed only to top up (one-time Stripe Checkout) or to enable auto-recharge. No hold is stated. Debit acceptance is not stated. |
| Limits |
Two hard limits that the seven-kind vocabulary cannot name. (1) There is no public IPv4 and no UDP ingress: 'Outbound: everything. Inbound: your call' is implemented as on-demand TCP port mappings with IP allowlists plus an HTTPS proxy for web traffic, so a WireGuard or QUIC listener cannot be reached from outside. (2) Concurrency is tiered: 3 Cubes running at once on Welcome, 10 after USD 15 of lifetime top-ups, 25 after USD 50, uncapped after USD 300. Cube size is the same on every tier: up to 16 vCPU, 32 GB RAM, 100 GB disk. |
| Binding | none What fails first is not one of the seven kinds: there is no UDP ingress and no public IPv4, so a WireGuard or QUIC listener cannot be reached. Recorded in limits[] as per-ip-shaping with the protocol limit spelled out rather than mislabelled as a quota. |
| Interface | ssh, rest, cli Root SSH on a per-Cube hostname and port, a REST API with API keys, and a dashboard. 'You log in as ubuntu ... Run sudo su for a root shell.' |
| Tooling | any SSH client; rsync/scp over the SSH mapping; the REST API for create/start/stop; no vendor rclone backend needed because it is a plain Linux box |
| Composes with | A USD 2.92 a month always-on Linux box with root, unmetered egress and no card at signup: the cheapest credible always-on target, usable as a monitor, a small web app behind Krova's HTTPS proxy, or a Docker host, but not as a WireGuard endpoint because only TCP can be published. |
| Reliability | domain registered 2026-03-14; prepaid credit is not refundable in cash; the disk is deleted 7 days after the balance reaches zero |
| Notes | The dossier already carries krova-cube at the 1 vCPU / 1 GiB / 10 GiB preset, USD 2.92. This record keeps that price and adds the shape that answers question: because the rate card is a-la-carte, 1 vCPU / 2 GiB / 10 GiB bills 0.0010 + 2 x 0.0025 + 10 x 0.00005 = USD 0.0065/hour = USD 4.745 a month at 730 h, which is 2 GiB of RAM for under USD 5. The nearest published preset, Micro at 1 / 2 / 20, is USD 5.11 and therefore over the line. 15 GiB of disk instead of 10 would be USD 4.93. Its credit is non-refundable in cash and its disk is deleted seven days after the balance hits zero, so it is a prepaid bet rather than a subscription. The domain is seven months old. Against that: a status page on UptimeRobot reports 99.996%, which is better evidence than most hosts in this price band publish. |
| Evidence rung | documented Rate card, presets, the 730-hour convention, the stopped-disk billing and the signup terms are quoted from the pricing page read today; root/sudo, the TCP-only port mappings and port 25 from the cubes documentation read today. What would raise it: a probe that runs a 1 vCPU / 2 GiB / 10 GiB Cube for 24 hours and reads the ledger, which would also settle whether a UDP mapping can be created. |
