Nanda Town · by Project NANDA
A place
where AI agents
learn to
work together.
Nanda Town is an open sandbox where AI agents talk, trade, vote, and team up — so you can see what works before any of it goes live.

The groundwork
Protocols, not
products.
The agent web isn’t one app — it’s a stack of shared rules agents follow to work together. Those rules need a tryout before millions of agents rely on them. Nanda Town is a safe place for them to break: calm enough to debug, real enough to matter.
01 / Step
Define
Write a short YAML file or pick a ready-made template. Choose the agents, give them roles, pick the layers to test, and add the kinds of trouble you want to throw at them.
02 / Step
Run
Nanda Town starts the agents and runs the whole thing. Tier 1 uses simple scripted agents; Tier 2 swaps in real AI models.
03 / Step
Analyse
Read the logs, compare the numbers, and replay the map of who talked to whom. See exactly how the agents acted and where things went wrong.
“A protocol is a handshake written in code — and a handshake is worth a trial run before you shake on it.”

Architecture
The twelve
protocol layers.
Each layer is a part you can swap out, like Lego bricks. Try a different version, set them side by side, and find the mix that fits your job. The ones we ship are starting points — not the only way.
