Playground

See it work. Verify it yourself.

Seven tools over real Treeship receipts and the actual verifier compiled to WebAssembly. Nothing here trusts a receipt's own word for it. Flip a byte and the signature really breaks; a receipt with no envelope reads structural-pass, not verified.

suggested path: Hub → Resolve → Verify → Explorer

The directory

Look up any agent, the way you would a certificate.

Hub→

Browse the agent registry with honest trust grades, then resolve anyone.

Resolve→

Look up an agent and grade it against the roots you pin. Your machine decides.

Trust→

Inspect a real signed capability card. Signature valid is not the same as trusted.

Analyze a session

Read what an agent actually did, from real receipts.

Explorer→

Watch a multi-agent session fold into one signed Merkle root.

Compare→

Diff two runs and catch what a summary hides, like a silent model swap.

Inspector→

Run a receipt through a policy battery. A perfect score is still structural-pass.

The cryptography

The part that is not a demo.

Verify→

The real Ed25519 verifier in your browser. Tamper any byte and the signature genuinely fails.

Every tool runs locally in your browser and folds into the same idea: every receipt folds into one signed root, and anyone can check it against roots they choose to trust. No server in the loop, no bytes leaving your machine.
