ServiceStack Studio is a capability-based UI to manage multiple remote ServiceStack instances from either a Chromium Desktop App or cross-platform .NET Core Web App.
The richer metadata in ServiceStack Services allows Studio to logically group Services around Data Models, enabling its high-level semantic features like its native data-grid like UX over all AutoQuery Services to quickly discover, search, create, update and delete entities based on the available AutoQuery APIs and whether Authenticated Users have access to them.
Install the app dotnet tool then launch with:
Studio replaces the ServiceStack Admin UI where it provides a UX-friendly UI for accessing AutoQuery & Crud Services but will also gain UI features for taking advantage of various ServiceStack Plugins & Features, e.g. in this initial release it includes UI’s for Managing DB Validation Rules & for viewing the Executable Audit History of Tables updated through AutoCrud Services.
Studio capability-based Admin UI is enabled via the
/metadata/app endpoint which returns metadata information about which plugins are enabled, what features they’re configured with and what User Roles they’re protected behind (if any). As such it’s only able to manage v5.9+ ServiceStack instances.
You’ll need the latest app dotnet tool which is bundled with the latest Chromium which provides the Desktop UI:
$ dotnet tool update -g app
Which you’ll need to run once to register the
app:// url scheme, e.g:
$ app -version
Starting ServiceStack Studio
This initial release of ServiceStack Studio primarily provides a UI around AutoQuery Services and the latest features in this release like Executable Audit History and declarative RDBMS validators.
If you don’t have a project using the v5.9+ features on hand you can launch a copy of NetCoreApps/NorthwindCrud which uses the new AutoCrud features to generate AutoQuery Services around all its RDBMS tables, that can be run locally with:
$ x download NetCoreApps/NorthwindCrud $ cd NorthwindCrud $ dotnet run
Where you can use
app URL scheme support to launch Studio & automatically register the NorthwindCrud instance with:
This URL scheme gets translated & is equivalent to running Studio on the command-line with:
$ app open studio -connect https://localhost:5001
connect param is used by Studio to auto register the remote NorthwindCrud instance where it auto downloads its App Metadata containing its enabled plugins & features & within a few seconds you should see it appear on the home page:
Desktop-less x-plat app
Whilst not optimized for it, Studio can also be launched headless in your default Browser using the
x x-plat tool:
$ x open studio -connect https://localhost:5001
Where you’ll then be able to view it by going to
https://localhost:5002. Note if not launched in a browser Studio will have limited capacity and features, but will eventually be a supported mode for accessing Studio from macOS or Linux.
From the home page you’ll see all the top-level Admin Sections available that’s enabled on the remote instance, in the initial release there’s a UI for Managing Users, accessing AutoQuery Services and a UI for maintaining DB Validation Rules which automatically appear against each remote ServiceStack instance depending on whether they have each feature enabled or not.
For ServiceStack instances with the
AdminUsersFeature plugin, Admin users will be able to manage system users, change their passwords, Assign Roles & Permissions, temporarily Lock or permanently delete users. The plugin is highly flexible with graceful support for all Auth Providers, custom UserAuth data models and configurable editable & queryable fields.

Studio’s AutoQuery UI provides an instant intuitive UI around your ServiceStack AutoQuery Services allowing users to immediately hit the ground running and input system data as per their fine-grained authorization rules and configured validation rules.

AutoQuery + Studio Demo
To see how productive the power combo of AutoQuery + ServiceStack Studio is together checkout the AutoQuery CRUD Bookings Demo showing how to create a multi-user Bookings System from scratch within minutes.
For ServiceStack instances that have a Validation Source registered, Admin users will be able to specify additional Validation Rules & have them immediately applied at runtime, where they’ll be instantly verified in all existing ServiceStack Apps with Validation enabled without any changes.

Studio Desktop App vs ServiceStack.Admin
The primary limitations with ServiceStack Admin was its deployment model where it had to be explicitly registered as a plugin in each ServiceStack instance, this means it could only be used on ServiceStack instances that explicitly had it registered, also it maintained the long release cadence of ServiceStack major releases which means the UI couldn’t be updated frequently resulting in a stale long feedback loop.
Frequent out-of-band release cadence
To overcome this ServiceStack Studio is delivered as a Gist Desktop App which, like a website will be running the latest version each time it’s run. To reduce its download footprint the
x dotnet tools now include the new ServiceStack.Desktop project which includes the common framework libraries that most Vue & React Apps use which saves it from needing to be included in each Download. It also includes Google Material Design Icons SVGs & a copy of fontawesome free icons that all Desktop Apps will be able to use without the bandwidth cost for using them.
Light Footprint + Always use latest version
ServiceStack/Studio is a vue-lite App that only uses SVG icons as they’re small, high-quality at every scale, are customizable & have built-in css classes making them easy to use declaratively where it takes advantage of ServiceStack’s built-in SVG support which allows optimal css bundles containing only the SVGs your App’s use. All SVG icons used in Studio are defined in its _init.ss startup script which defines which Material Design SVG to make available under which css bundle. It also registers its own custom SVG icons not contained in ServiceStack.Desktop’s embedded resources and includes them as part of its
As a result of its architecture Studio gets bundled down to a 55kb .zip which includes its 46kb (Uncompressed)
Studio.dll plugin containing all its C# back-end logic (thanks to all ServiceStack .dll’s being deployed with the dotnet tools as well). As it’s published as a Gist it adds a bit more overhead (and Gist APIs aren’t particularly fast) so there’s a slight delay in loading from a Gist but still is able to load its home page in around 2-3s, which includes the start time of the ServiceStack .NET Core App and the Chromium CEF Browser. The number of restarts should be minimal thanks to Studio being designed as a single UI to manage all your ServiceStack instances so you can reuse the same running Desktop App to manage multiple remote ServiceStack instances.
