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.

Packer features and specs

  • Multi-Provider Support
    Packer supports a wide variety of providers such as AWS, Azure, Google Cloud, VMware, and more. This allows for flexibility and the ability to create machine images across different environments.
  • Automation
    Packer automates the creation of machine images, eliminating the need for manual image configuration and reducing the potential for human error.
  • Script Reusability
    Packer allows for the reuse of scripts and configuration files, enabling a consistent and repeatable process for image creation.
  • Parallel Builds
    Packer can build multiple images in parallel, which can significantly speed up the provisioning process.
  • Idempotency
    Packer ensures that the output machine image is always an identical result given the same input configuration, reducing the risk of inconsistencies.

Possible disadvantages of Packer

  • Steep Learning Curve
    The variety of features and flexibility that Packer offers can make it complex and challenging to learn, especially for beginners.
  • Limited Debugging Tools
    Packer's debugging tools are not as mature or as integrated as those found in some other DevOps tools, making troubleshooting more difficult.
  • Configuration Complexity
    Complex configurations with multiple builders and provisioners can become hard to manage and maintain, leading to potential errors.
  • No State Management
    Unlike Terraform, Packer does not manage state, which means users need to handle state management separately if required.
  • Dependency on External Tools
    Packer often relies on external scripts and tools for provisioning, which can introduce additional dependencies and complexities.

Questions & Answers

As answered by people managing Packer 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.

Introduction to Top Open Source Virtualization Tools
Packer is notably light, high performing, and operates on every major operating system. It assembles and configures all the necessary components for a virtual machine then creates images that run on multiple platforms. Packer doesnโ€™t replace configuration management tools like Puppet or Chef; as a matter of fact, when creating images, Packer can utilize tools like Puppet or...

  • Failed to connect to the host via SSH on Ubuntu 22.04
    If you have just upgraded to Ubuntu 22.04, and you suddenly experience either errors when trying to ssh into hosts, or when running ansible or again when running the ansible provisioner building a packer image, this is probably going to be useful for you. - Source: dev.to / almost 4 years ago
  • Create a minimalist OS using Docker Containers and Hashicorp Packer
    I am already using Hashicorp Packer at work and for personal projects and I wanted to test This idea out by wrapping it a single Packer Template file. This reduces the level of maintaining a lot of small scripts, Dockerfiles and configurations and the user can simply trigger a couple of Commands to get a minimalist OS at the end of the process. - Source: dev.to / almost 4 years ago
  • After self-hosting my email for twenty-three years I have thrown in the towel. The oligopoly has won.
    And while it is a slight increase in complexity, it can be an overall net gain in functionality, configurability and reliability. Much like Packer is far more reliable and practical than manually making VM images sitting in front of a terminal, even though making the initial configuration takes some time.

  • Customized Ubuntu Images using Packer + QEMU + Cloud-Init & UEFI bootloading
    Hashicorp Packer provides a nice wrapper / abstraction over the QEMU in order to boot the image and use it to set it up on first-boot. Instead of writing really long commands in order to boot up the image using QEMU, Packer provided a nice Configuration Template in a more Readable fashion. - Source: dev.to / about 4 years ago
  • The journey of sharing a wired USB printer over the network
    Packer seemed like the perfect tool for the job. I have never used it before and wanted to get familiar with the tool. It doesn't come with ARM support out of the box, but there are two community projects to fill that niche. - Source: dev.to / over 4 years ago
