Download Workflow Engine for .NET 6, 8, and 10

Workflow Engine on modern .NET, formerly .NET Core. Cross-platform, runs on Windows, Linux, and macOS, and picks up new framework features first. The packages are the same as on .NET Framework, so a host migration later is a runtime change, not a rewrite.

Add the runtime and a database provider

Two NuGet packages: the core runtime and the provider for your database. All six providers work on modern .NET.

Designer packages for your front end

Embed Workflow Designer in your web app with the npm package for your framework. Vue and any plain page use the vanilla package, shown with a running sample on the JavaScript workflow designer page; React renders the wrapper component, shown with a running sample on the React workflow designer page; Angular imports the wrapper's module, shown with a sample that passes ng build on the Angular workflow designer page; Blazor embeds the designer through IJSRuntime interop, shown file by file on the Blazor workflow designer page. Every framework path is covered on the workflow designer page.

Why this build and not .NET Framework

Use modern .NET for any new project, any cross-platform target, and any host on .NET 6 or later. The engine's API surface is identical on both runtimes, and Oracle and SQLite persistence are available only here.
