Yakuza.sh puts 3,691 verified tools inside your Unity Editor — through Claude Code, Codex, Copilot, or opencode. Every tool checked one by one, no black boxes, no debts owed to anyone. Same engine as Buril. Different oath.

Works with the agents you already use
Yakuza.sh 3,691 tools
Claude Code and Claude Desktop via .mcpb · Codex and Copilot via their native MCP config · opencode too. Unity 6 and up.
Not a video. The same HTML, CSS and JavaScript as the desktop app, loaded straight into this page. Give it an order and see what comes back.
Honesty: the interface is the production one, the answers are demo scripts. The only real number on this panel is 3,691 tools, verified on 2026-09-10 against the bridge. Voice dictation shows as off because it needs the desktop app: the web does not lie about that.
Connect your VRoid Hub account, pick a character from your favorites or your own, accept its conditions of use, and see it right here — loaded through the same official API Buril uses inside the Unity Editor.
Application under review by the VRoid Hub team. Meanwhile VRoid Hub shows an unapproved-app notice and applies stricter limits: the demo works all the same.

The model loads in your browser and is not stored on our servers. The download license is invalidated when done. You can disconnect the account whenever you want.
The author of this model declared these conditions on VRoid Hub. By continuing, you agree to respect them.
Each capability below is a set of catalog families, with today's real count. The numbers come from the catalog; families are named exactly as they exist in the bridge.
Describe a level and the agent builds it: terrain, props, lighting, post-processing, navmesh. From a reference image if you want.
Netcode for GameObjects, Photon Fusion or Quantum. Pick the stack and the agent wires it, syncs it, and throws network chaos at it to see if it holds.
The agent plays your build: gets in, walks, shoots, reads the console, finds the bug, fixes it and plays again until it passes. Without you there.
When the agent compiles, enters Play or switches scenes, Yakuza.sh brings the Unity window to the front on its own. Unity runs slower in the background, and without this the session ends up waiting for your click. Windows for now.
Builds, reads the report, diagnoses why it weighs 400 MB or why it fails on iOS, and fixes it. Cloud Build and Xcode post-build included.
Visual similarity search (CLIP, on your machine), procedural mesh, and the image → 3D model → rigged prefab chain, inside Unity.
Every Yakuza.sh row names the catalog families backing it up. Competitors appear as they are: the ones that need a separate server to run say so.

The Yakuza.sh column comes from the same bridge catalog as buril.ai, as of 2026-09-10: every "yes" names families that exist there. AnkleBreaker is a Node (npm) MCP server plus a UPM plugin, two pieces installed and started separately — that is why its cells say "with a separate server". The other competitors' data comes from our 2026-05-08 benchmark and has not been re-verified since; this market moves fast. If you find a stale fact, write to us and we will fix it: we prefer an uncomfortable table to a pretty one.
We do not sell credits, or a chat, or a browser demo.
We sell 3,691 tools that already work, with Undo, inside your Editor.
If you want an assistant that suggests, there are many. If you want the game finished, there is one.
Free brings the 243 tools equivalent to the free MCPs, with no separate server. From Indie up, the whole catalog with no quotas: we do not limit usage on any plan.
To try it for real, not just for a while.
Forever. No card.
For those who already use it every day and want the Editor in their pocket.
Billed monthly. Cancel anytime.
For a small team sharing a project and a pipeline.
3 seats included · +$45 per extra seat
For the team that needs more seats, with openmon Source included.
5 seats included · +$45 per extra seat
For the studio that cannot let a file leave its network.
Let's talk and scope it.
Talk to us
What "no quotas" means, exactly. Yakuza.sh does not meter, count or cap: there are no credits to run out of, because credits do not exist.
And what it does NOT mean. Your model is not unlimited. The only cap is your Claude, OpenAI or whoever's plan — the one you already know, manage and pay for. We say it this plainly so you can verify it before paying us, not after.
And everything Yakuza.sh generates is yours. Scripts, prefabs, scenes, configuration: no copyright of ours, no license of ours, including work you deliver to a client and bill for. If you stop paying, you stop using Yakuza.sh — you do not lose your game.
openmon.io is the Monster Capture Engine: the engine to make your own creature-capture game in Unity. Sold separately, one-time payment. With Yakuza.sh, each plan brings an edition, and the edition rises with the plan.
How the license works. While your Yakuza.sh subscription is active, you have the openmon edition that matches your plan: Indie includes Basic; Enterprise, Studio. Lite is sold separately.
If you cancel, you lose access to openmon — but you keep everything you built with it, without restriction, forever. Same as with the rest of Yakuza.sh: not paying does not take your game away.
The same pattern Notion uses: sign in with your account, and your plan decides what the connector enables. No copying tokens by hand.
One click. You accept the terms and the privacy policy in the same step, with both links in view before accepting.
One .mcpb file for Claude Desktop, or claude mcp add for Claude Code. Codex, Copilot and opencode read the same MCP configuration. Guide per client →
Free connects the Editor on your machine with 243 tools. Indie and up bring all 3,691 and the relay: the same project from ChatGPT or your phone, without opening ports.
The bridge runs locally by default. Your files never leave your machine unless you turn the relay on, on purpose.
What we have is the product, not the distribution. Help us with the second.
A real WebGL build of the engine, fully offline: it connects to nothing and asks for no account. This is what a Yakuza.sh rank includes.
It downloads only when you press. Keyboard and mouse.
This demo is for illustrative purposes only. Pokémon and all related characters, names, creatures and assets are property of Nintendo and The Pokémon Company, and all rights belong to them. openmon MCE is an independent engine and is not affiliated with, endorsed or sponsored by them.
Accounts, plans and the connector open in the coming weeks. Meanwhile, the hub and the openmon demo run right here.
