## Pricing regimes (raw)


## Features

Yes: ≥24 h sessions, self-hosting, open source, inbound access rules, firewall inside (nftables)

No: none recorded

Unknown: everything else. Evidence (source + quote) per feature: https://battleships.dev/data/providers/kubesail.json → feature_evidence

## Caveats

- Discontinued or closed to new customers, confirmed on the live site 2026-09-29. The homepage says KubeSail operated from 2019–2025 and is no longer accepting new users or selling hardware. The docs remain online for existing PiBox owners. /pricing returns 404. No live tariff exists.
- Home self-hosting product; /pricing 404. Customer devices/clusters and hosted relay/control plane are different. No verified standalone cloud sandbox compute rate.
- Null values mean unknown, not free/unlimited. No model-token cost, tax or unverified ancillary charge included.
- Native browser/device/task/credit prices with unknown CPU/RAM are deliberately non-priceable. Check regime before interpreting any partial resource estimate.

## Verified billing facts and gotchas

1. Home self-hosting product; /pricing 404. Customer devices/clusters and hosted relay/control plane are different. No verified standalone cloud sandbox compute rate.

## Worked example

Requested: 4 vCPU/8 GiB, 50 simultaneous × 8 h/day × 22 days = **8,800 instance-hours**, 30% CPU; 50 GiB snapshots and 100 GiB egress. A month is 730 hours only when explicitly used in rate conversion.

**Total: unknown.** This product does not publish a verified complete 4-vCPU/8-GiB tariff and/or the service bills a different unit. Fifty concurrent instances and eight-hour sessions are not automatically supported. Neither 30% utilization nor retained snapshots can be converted into free resources. Use the native plan terms above and request the missing CPU/RAM, retention, egress and concurrency quote.

Page captures and documentation indexes/bundles are in `raw/`; provider JSON lists the evidence paths. HN query results were captured separately as `<id>--hn.txt`; they are discovery leads, not current tariff authority. Downloaded docs do not imply every feature was verified; unsupported assertions remain null.
