Neblla — build and publish multiplayer apps and games with AI

Neblla is a platform to build multiplayer web apps and games. Add one script tag and your HTML app gets rooms, real-time messaging (P2P WebRTC or server), player accounts and saved data, friends, in-app purchases and built-in AI, with no backend to run. Apps are hosted on play.neblla.com and listed in a public gallery.
