🛰️PublicAI Trajector CLI

Turn your own Claude Code sessions into compensated data contributions, one project at a time, with nothing captured until you say so.

Trajector CLI

Trajector is an open-source command-line tool. With your explicit per-project consent it routes that project's Claude Code API traffic through a proxy on your own machine, records the raw request and response, masks secrets locally, and uploads only the redacted result.

Nothing is captured until you opt a project in, and every project you have not opted in is structurally incapable of being captured — not by policy, but because the code path does not exist for it.

Status: beta. Releases before 1.0.0 are published as pre-releases. macOS and Linux are supported; Windows is in beta.

What it does

trajector enable, run inside a project, writes project-local Claude Code settings that point that project's API traffic at a local reverse proxy bound to 127.0.0.1:41100. The proxy forwards every request verbatim to the configured upstream and records it on the side.

• Forwarding is sacred. Any failure on the recording side — disk full, malformed stream, internal error — never interrupts forwarding. Streaming responses pass through unbuffered.

• Recording is unobservable. What the proxy sends upstream does not depend on whether the exchange is being recorded.

• Consent is the routing key. A per-project token decides what may be recorded. Requests without a valid token are forwarded and never recorded.

• Credentials never touch disk. Authorization and x-api-key are not written to any file, in any state.

• Consent is revocable. disable, logout, and uninstall each undo a different amount, immediately.

The proxy starts on demand, exits when idle, and is never a permanent daemon.

The shape of a session

claude  ──►  127.0.0.1:41100  ──►  api.anthropic.com
                    │                (or your own relay)
                    └──►  spool  ──►  redact  ──►  upload

Recorded calls wait in a local spool with a bounded disk quota. Secrets are masked on your machine, and only redacted batches are uploaded. An upload is only considered done once the service acknowledges it by batch id.
