Playco

aid: playco
name: Playco
description: 'Playco is an instant-play gaming company founded in 2020 by Justin Waldron, Michael Carter, Takeshi Otsuka and
  Teddy Cross, headquartered in Tokyo with teams worldwide. It builds HTML5 games that run inside social and communication
  platforms without an app install — EverWing on Facebook, Snake Squad on Snap Games, Heads Up! for Zoom, Sway Stories on
  TikTok and Trip Royale on LINE — and reached unicorn status on a $100M Series A. Its technology stack, described on play.co/tech,
  is developer tooling rather than a public web API: PixiJS (the open-source HTML5 rendering/creation engine it acquired with
  Goodboy Digital in 2021), Odie3D (a 3D extension framework), GCInstant (a client-side JavaScript library wrapping platform
  SDKs and analytics) and Replicant (a backend-as-a-service state manager for instant games). Playco publishes no developer
  portal, no API reference and no machine-readable contract; its public code surface is the play-co GitHub organization, which
  is the renamed Game Closure organization and carries the legacy devkit HTML5 game platform, js.io and ff.'

  reason: no-developer-program
  detail: Playco is a consumer instant-games studio with no developer program at all — the play.co navigation is About / Games
    / Tech / Career / Discover, api.play.co, developer.play.co and docs.play.co do not resolve, and the three technologies
    it markets to developers (GCInstant, Replicant, Odie3D) ship as internal client-side game tooling that is not published
    to any package registry.
