Live dashboard demo

Try Pacto without installing anything. The dashboard runs entirely in your browser: the engine and a set of demo contracts are compiled to WebAssembly (a format browsers run directly). No backend, no live registry, nothing leaves the tab.

The whole engine ships to your browser, so the first visit downloads about 11 MB of compiled Wasm (57 MB unpacked). Give it a moment on a slow connection — the loading strip counts the seconds and names the size, and the browser caches it afterwards.

Two things about the fixture are deliberate. It opens on a degraded-source banner — one source unavailable, one partial, because a view that only shows complete knowledge teaches you nothing about the day it isn't. platform-app-config appears twice — two different services from two sources that share a name. A name is not an identity, so the graph keeps them apart.

What to look at

  • Fleet overview — eighteen services spanning edge, domain, infra, platform and external tiers. Open it on the degraded sources and the duplicate name described above.
  • One service's dependency graph — payments-service spans six published revisions. Resolves from each contract's declared dependencies and highlights what a change would reach.
  • Data sources panel — shows one source degraded and one unavailable. The operational graph reports what it knows and what it cannot know, and the day everything reports complete is not every day.
  • Change analysis — the v1.2.1 → v2.0.1 step removes the /charges API and shows which consumers the break reaches.

What it cannot show

There is no cluster behind the demo. The compliance states on its targets are recorded fixture data. It shows runtime conformance (what a service really does on the network) as one recorded finding, not a live check: the staging orders-service target carries INTERFACE_ABSENT, and its evidence line says "seen by: Kubernetes + kernel". A live check needs the node agent on a Kubernetes cluster or the Docker Compose demo.

To run the dashboard against your own services, see Dashboard container. The source and build harness live in examples/demo.

Next: the Docker Compose demo runs the same UI against a real registry and Evidence Server on your machine. The guided tour reaches the same facts from the command line in six offline user stories. Or go straight to the Quickstart and write a contract of your own.
