Klang Games

Klang Games is an entertainment and game development studio headquartered in Berlin, founded in 2013 by three Icelandic co-founders — Mundi Vondi (CEO), Oddur Snær Magnússon (CTO) and Ívar Emilsson (CCO) — several of whom came out of CCP and EVE Online. Its flagship product is SEED, a persistent large-scale MMO society simulator built on Google Cloud, backed by investors including Animoca Brands, Supercell, LEGO Ventures, Anthos Capital, Kingway Capital and Northzone. Klang publishes no developer platform: there is no API documentation, no SDKs and no partner program. The only publicly discoverable machine interface is the OpenID Connect provider behind SEED player accounts, captured in this repo from its discovery documents.

Klang Games publishes 1 API on the APIs.io network. Tagged areas include Company, Consumer, Gaming, Game Development, and MMO.

Klang Games’ developer surface includes engineering blog, support, signup flow, authentication, and 13 more developer resources.

scored 2026-09-08 · rubric v0.20.0
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/klang: open an issue to ask a question, or submit a pull request to add artifacts.
