A GDS-style service blueprint / service-design engine — domain model, calculation engine, state-machine engine, and a compiled visual editor web component. Framework-agnostic: no Umbraco, no ASP.NET Core MVC, no hosting assumptions baked in.
Wayfinder was extracted from Umbraco Prism,
which is now a consumer of these packages rather than their owner. A host application —
Umbraco-based or otherwise — layers its own tenancy, auth, and rendering opinions on top.
Wayfinder.Umbraco is the Umbraco-hosted
implementation Prism itself uses.
See it running
Wayfinder.AppHost + Wayfinder.ReferenceApp is a small, self-contained .NET Aspire host in
this repo — every package wired together, real GOV.UK Design System rendering, a demo login,
and a seeded "apply for a licence to hold a juggling event" journey. It's the fastest way to
see what a working Wayfinder host actually looks like, and exactly how little wiring a real
host (like Wayfinder.Umbraco) collapses into. Run it with
dotnet run --project Wayfinder.AppHost, or the "C#: Aspire (Full Stack)" launch config in
VS Code. See docs/guides/reference-app.md for what it
implements, how the demo blueprint is seeded from JSON and only saved in memory, and what a
real host does differently.
Packages
| Package | Purpose |
|---|---|
Wayfinder |
Core domain models (ServiceBlueprint, ServiceRequestResponseEnvelope, etc.), the declarative calculation engine, and the sanitizer interface. Zero framework dependency. |
Wayfinder.Engine |
The service blueprint state-machine engine — queue routing, gateway evaluation, request persistence. |
Wayfinder.Engine.Api |
REST toolkit (MapServiceBlueprintAuthoringApi()) exposing service blueprint authoring — list/read/validate/save/simulate — over HTTP for any ASP.NET Core host. |
Wayfinder.Engine.Mcp |
MCP-over-HTTP toolkit (MapServiceBlueprintAuthoringMcp()) — the same authoring surface as MCP tools for AI agents. |
The service blueprint model
A ServiceBlueprint describes a journey as queues (named work queues), stages (each
owning its own routes), and gateways (first-class Split/Join routing nodes — a stage's
routes must always target a gateway, never another stage directly). See
docs/guides/reference-service-blueprint-contract.md
for the full authoring schema, and
docs/guides/calculation-language.md for the
declarative expression language used in calculations and showWhen.
AI-ready authoring
Service blueprint authoring is exposed to AI agents (Claude Code or any MCP client) the
same way it's exposed to a human editor: as a toolkit a host app wires into its own
pipeline. Wayfinder.Engine.Api and Wayfinder.Engine.Mcp map the same
list/read/validate/save/simulate operations as REST and MCP-over-HTTP respectively, both
calling straight into a host's live Wayfinder.Engine in-process. See
docs/guides/ai-service-blueprint-authoring.md.

|---|---|
|
Wayfinder.Engine
Umbraco/Umbraco.Cms-independent GDS-style blueprint state-machine engine (queue routing, gateway evaluation, instance persistence) used by Umbraco Prism. Reusable by any .NET host building its own blueprint-driven business app. |
|
|
UmbracoPrism
Multi-tenancy for Umbraco (v17+) with dynamic branding and stateless identity. |
|
|
Wayfinder.Umbraco
Umbraco-hosted implementation of Wayfinder service design — a DB-backed, uSync-portable service blueprint store, a backoffice authoring API, and two Block Grid-composable building blocks (a citizen-facing stage journey and a caseworker-facing worklist) for any Umbraco v17+ site. An authoritative in-process engine, real multi-queue support, no multi-tenancy or auth opinions of its own; a host wires its own identity/tenant resolution on top. |
|
|
Wayfinder.Rendering.GovUk
Default GOV.UK Design System rendering for Wayfinder's Component/FieldRenderPayload catalog — plain C#, no Razor/ASP.NET Core MVC dependency, so it works from a minimal-API host as well as an MVC one. Ships one function per component/field type, plus a small override registry for hosts that want to replace or extend individual types. Also ships GovUkStageJourney — the blueprint-agnostic glue (form-body rendering, file-download/bulk-dataset URL injection, posted-form field coercion) every host route rendering a stage otherwise hand-copies. Also ships the real vendored govuk-frontend package itself, the CSS/JS the slider/stat-group/chart/live-form markup needs (no GOV.UK Design System equivalent exists for these), and the poll/init boilerplate every host otherwise re-writes — all as static web assets at /_content/Wayfinder.Rendering.GovUk/, version-locked to what this package's own generated markup actually targets, so every host loads the same files instead of hand-copying its own. |
