AI Governance Infrastructure — open gateway demo. Self-hosted systemprompt.io gateway in a single Rust binary: policy, audit trails, and cost attribution on every AI request, with the Systemprompt Bri
Private, managed Claude Cowork. Five minutes from sign-up.
Sign up, get $1 of credit, download the Bridge, and Claude Cowork and Claude Desktop are configured for you automatically.

This repository is the source of demo.systemprompt.io, the hosted demo of systemprompt.io: a governed /v1/messages gateway you sign up for, plus the Systemprompt Bridge desktop app that connects Claude Cowork, Claude Desktop, and Claude Code to it. Built on systemprompt-core, published on crates.io as systemprompt.
