DotForge is a SaaS starter kit for .NET 10 and Angular 22, extracted from production software rather than written for a demo: multi-tenant JWT auth, EF Core with generated tenant query filters, an ErrorOr result pipeline, FluentValidation, Aspire orchestration, CI on GitHub Actions, and a complete demo app you can run with one command. Skip the months of plumbing and start on your actual product.

    Karaf comes with comprehensive tooling support including a powerful CLI, web console, and various tools for monitoring and managing the runtime environment. These tools simplify everyday management tasks.

Possible disadvantages of Apache Karaf

  • Steeper learning curve
    Due to its modular and extensible nature, Apache Karaf can have a steeper learning curve for new users, especially those unfamiliar with OSGi concepts and enterprise middleware.
  • Resource intensity
    Running and managing an Apache Karaf instance can be resource-intensive, especially when dealing with large-scale or highly modular applications. Adequate memory and processing power are required to maintain optimal performance.
  • Complex deployment
    While Karaf can handle complex deployment scenarios, setting it up and configuring it properly can be more involved compared to other simpler solutions. This complexity can increase the initial setup time and effort.
  • Limited community support
    Despite being an Apache project, the community around Apache Karaf might not be as large or active as other popular frameworks, potentially making it harder to find ample resources or immediate support.
  • Dependency management challenges
    Managing dependencies in Karaf, especially when dealing with multiple third-party libraries and their versions, can become cumbersome and lead to conflicts if not handled carefully.

Questions & Answers

As answered by people managing Apache Karaf and DotForge.dev.

What's the story behind your product?

DotForge.dev's answer:

I kept rebuilding the same three months of plumbing. Every new SaaS project started with the same multi-tenant auth, the same tenant isolation, the same design system, the same wiring, before any actual product work could begin.

DotForge is that layer, taken out of software that runs in production and generalized so it carries no domain of its own. What ships is the infrastructure, plus a demo application you can delete in ten minutes once you have seen it work.

How would you describe the primary audience of your product?

DotForge.dev's answer:

.NET developers building SaaS products, and the consultancies and freelancers who start client projects from scratch. People who are already productive in C# and Angular and would rather not learn a different stack just to ship a multi-tenant application.

What makes your product unique?

DotForge.dev's answer:

DotForge is the only SaaS starter kit built on .NET 10 with Angular 22, both current releases. The existing .NET kits are anchored on .NET 7 or 8 and, when they ship a frontend at all, on Angular 16 or React.

It was extracted from production software rather than written for a demo: the infrastructure layer of a real multi-tenant application, generalized into a kit. That includes a 48-component design system of its own, with no Material, no PrimeNG and no UI library underneath.

Why should a person choose your product over its competitors?

DotForge.dev's answer:

Tenant isolation is proven, not claimed: cross-tenant access returns 404 rather than 403, so one tenant cannot even learn that another tenant's data exists, and integration tests assert it across every verb. The filters are generated from a marker interface instead of hand-copied per entity, and the write interceptor fails closed.

One command gets you a running product. aspire run boots PostgreSQL, migrations, the API and the SPA; you sign in with printed credentials and land on a working dashboard with real data, not a skeleton.

And the design system is yours: no UI library to fight, no theme to override, dark and light from the same components.

Which are the primary technologies used for building your product?

DotForge.dev's answer:

Backend: .NET 10, ASP.NET Core Minimal APIs, Entity Framework Core 10, PostgreSQL (SQLite for zero-Docker development), .NET Aspire, ErrorOr, FluentValidation, Mapster, xUnit.

Frontend: Angular 22 standalone and zoneless, TypeScript 6, Tailwind CSS v4, Signal Forms, Vitest.

CI: GitHub Actions.

Who are some of the biggest customers of your product?

DotForge.dev's answer:

None yet. DotForge goes on presale on September 22, 2026, and has not been sold to anyone. The code it is built from has been running in production for years, but the kit as a product has no customers to name.

Apache Karaf mentions (1)

  • Need advice: Java Software Architecture for SaaS startup doing CRUD and REST APIs?
    Apache Karaf with OSGi works pretty nice using annotation based dependency injection with the declarative services, removing the need to mess with those hopefully archaic XML blueprints. Too bad it's not as trendy as spring and the developers so many of the tutorials can be a bit dated and hard to find. Karaf also supports many other frameworks and programming models as well and there's even Red Hat supported... Source: over 5 years ago
