Platonic

by Referential.ai

A self-hosted agent server for visible, replayable work.

Plato Agent is the client distribution built on Platonic. Model calls, tool calls, and policy decisions cross typed boundaries into a replayable ledger.

Why Platonic

A common foundation, made concrete.

Platonic is the server: it owns workspaces, agents, threads, tools, policy, approvals, and ledgers. Plato Agent is the client distribution that makes those boundaries visible.

Diligence by design

Visible by construction.

The ledger is the run. Interfaces, transcripts, recovery, and audits are derived from recorded facts rather than hidden control flow.
