Open WorldWeb Studio

Online Go with a neural network

govgo.ru

A gaming platform: live games against other players, play against the KataGo neural network, tsumego puzzles, game review, joseki, tournaments and a rating system. It works as an app on your phone.

Running and open for play.

What is inside

  • Live games against other people
  • The KataGo neural network runs on the player's own device
  • Several difficulty levels, from beginner to a strong opponent
  • Game review and daily puzzles
  • Player ratings
  • Installable on a phone and works offline
  • Joseki library and tournaments — in development

How it is built

The project's most interesting decision: the neural network runs in the browser, not on the server. So the site has strict code execution isolation, and the game scales its workload to the device — a phone computes lightly, a powerful PC goes full tilt. Server capacity does not grow with the number of players.

  • Node.js
  • Fastify
  • React
  • KataGo (WASM/WebGPU)
  • WebSocket
  • PWA

What the client gets

  • Heavy computation can move to the user's device — no server bill for it
  • Real-time games with no page reloads
  • A phone app without publishing to app stores
  • Full autonomy: no third-party scripts or external services

What we show on the demo

  • A live game against an opponent or the neural network
  • Automatic workload tuning to the device
  • Game review and puzzles
  • Installing the app on a phone

Why this matters for business

  • The cost of AI features barely grows with traffic
  • User data never leaves for a third party
  • The site stays fast with no external dependencies

How we work. Developers and AI agents work together on our projects: agents take the routine — breaking down the task, coding, checks, drafting copy — while decisions and accountability stay with a human. That is why we take on tasks that usually scare studios, faster and with less stress.
