Run a public sandbox Lake

A sandbox Lake is a real Lake with synthetic data only, open to anyone's agent, behind real HTTPS. It's where builders test end to end.

config ready · not yet deployed publicly

What you need

• A server with Docker, ports 80 and 443 open (any small VPS, or your own machine behind a router).
• A DNS A record for your sandbox domain pointing at it, e.g. sandbox.lake.example.

Start it

git clone https://github.com/thelakeprotocol/lake && cd lake
LAKE_DOMAIN=sandbox.lake.example \
  docker compose -f docker-compose.yml -f deploy/docker-compose.sandbox.yml --profile scale up -d

Caddy gets a certificate from Let's Encrypt automatically. One domain serves everything:

Path	What
/	the live map and the node's API (OpenAPI)
/t/<name>/a2a	100 hosted houses, each its own WebID, pod, wallet, card and rules
/ethics/, /auditor/, /payments/	the demo specialists

Point an agent at it:

const me = await joinLake({
  name: 'My study bot', domain: 'me.example', node: 'https://sandbox.lake.example',
  ethics: 'https://sandbox.lake.example/ethics', auditor: 'https://sandbox.lake.example/auditor', payments: 'https://sandbox.lake.example/payments',
  publicUrl: 'https://me.example',   // where the node can fetch your card
});

A sandbox skips domain proof and says so in every reply. Nothing in it is real: data, money, ethics approvals.
