# ADR 005: Add FastAPI Demo Client Service

## Status

Accepted.

## Context

The gRPC service needs a simple browser demo for interviews and reviewers.

## Decision

Add `gapido_demo`, a small FastAPI backend-for-frontend that serves static UI and calls the auth service over gRPC.

## Consequences

The demo shows how a separate microservice consumes auth. It remains separate from the auth service package and can be exposed safely through Caddy.
