Free tier[translated] Headline: 'A game server you can use for free, without limits'. The feature list gives 'Free' and 'Unlimited' as separate items, and the mechanism section says: 'When you start the OwnServer Client, a dedicated secure tunnel is created between OwnServer and your computer, and a public address dedicated to your server is issued.'

Bindingnone Nothing binds: the service is suspended. The announcement dated 2026/04/06 says operation has stopped temporarily and no restart date is set.
Identityanonymous [translated] The documented flow is: download the OwnServer Client, download the game server program, start the OwnServer Client, play with friends. No account, email or payment step appears in it.
Egress[translated] 'A game server you can use for free, without limits', with 'Unlimited' as a feature heading. No byte figure, no rate, no session length.; ingress: tcp+udp
free allowance: none published
Interfaceunknown [translated] 'OwnServer Client' is a per-OS desktop download; the page documents no API, no command line and no configuration file.
Toolingthe vendor's own desktop client only (Windows, Linux x86_64/ARM, macOS Intel/Apple Silicon builds listed); no CLI flag, no API, no .conf
Composes withnone while suspended; if it reopens it would be the only free Japanese host that publishes an arbitrary local TCP or UDP port without an account.
ReliabilitySuspended 2026-04-06 for stated stability and security problems; a client-side connection drop was patched with auto-reconnect in v0.10.0 (2025-04-20), which is the class of failure that preceded the suspension.
NotesThe live host answered twice with a transport failure (HTTP 530) on 2026-10-23, which establishes nothing about the origin; the archived capture of 2026-04-14 is what the record rests on. The vendor's game-specific page (ownserver.kumassy.com/games/custom) was seen only as a search snippet saying it publishes any TCP or UDP service, hence ingress is recorded from that snippet and not from a page read. Country: Japan; the operator writes in Japanese and names Japanese consumer ISPs as the problem it solves. Two blocks, either decisive: suspended, and identity-free but client-locked.
Evidence notedocumented The suspension is a dated sentence on the vendor's own front page. The protocol claim (TCP and UDP) rests on the vendor's per-game page, which this reader saw only as a search snippet.
