The full suite is live at demo.0815software.com — four apps on one platform, nothing to install. Sign in with owner@acme.test / demo-owner (single sign-on), or admin / demo-admin for the Documents app. The data resets every night.

Prefer to run it yourself? Clone the repo and start the whole stack — eight services and four app UIs, wired together — with one command. No vendor keys.

  • Single sign-on. Log into one app and PS-01 Identity signs you into all of them. The apps have no password of their own.
  • One action, many services. Finalizing an invoice assigns a gapless number, archives a PDF, emails the customer and records an audit event — one call, five services.
  • Real payment rail. PS-08 creates, confirms, settles and ledgers the payment — the same code path a real Stripe integration uses.
  • One audit trail. Every action from every app lands on a single tamper-evident hash chain you can verify.
