PipeForge is a lightweight, composable pipeline framework for .NET. It makes step-based processing simple, discoverable, and testable. Inspired by middleware pipelines and modern dependency injection patterns, PipeForge gives you structured control over sequential logic flows - without the ceremony.
PipeForge is available on NuGet.org and can be installed using a NuGet package manager or the .NET CLI.

While PipeForge is fundamentally a pipeline framework, it can also serve as the foundation for higher-level workflows. These workflows are built by composing individual pipeline steps that handle branching, retries, fallbacks, and decision logic - making it ideal for orchestrating complex processes like AI chains, data enrichment, or multi-stage validation.
| Game Loop and Simulation Ticks | Model turn-based or tick-based game logic using structured steps for input handling, state updates, AI, and rule enforcement. Ideal for simulations, server-side logic, or deterministic turn resolution. |
| Middleware-Style Request Processing | Build lightweight, modular request pipelines similar to ASP.NET middleware, without requiring a full web host. |
| DevOps and Automation Pipelines | Express deployment checks, file transforms, and system hooks as repeatable, testable steps. |
| Security and Auditing Pipelines | Enforce policies, redact sensitive data, and log events in a structured, traceable flow. |
| ETL and Data Processing Pipelines | Break down validation, transformation, and persistence into clean, maintainable processing steps. |
| LLM and AI Workflows | Orchestrate prompt generation, model calls, fallback handling, and response parsing using composable pipelines. |
| Business Logic and Domain Orchestration | Replace brittle if chains and nested logic with clearly structured rule execution and orchestration flows. |

You can generate and open a test coverage report by running the following command in the project root:
pwsh ./test-coverage.ps1Note
This is a Powershell script. You must have Powershell installed to run this command. The command depends on the global installation of the dotnet tool ReportGenerator.
