mizrael/OpenSleigh

OpenSleigh is a .NET framework for building distributed saga-based workflows, providing a message bus for orchestrating long-running processes across microservices. It supports multiple transport backends, including RabbitMQ, Kafka, and in-memory providers, alongside persistence layers for SQL Server, PostgreSQL, and MongoDB. The system includes built-in outbox patterns for reliable message delivery, state querying capabilities, and comprehensive tooling for testing and monitoring saga lifecycles.

How it got here

2020–2021 · Persistence and transport expansion

This period focused on expanding the framework's capabilities by adding new persistence providers (MongoDB, SQL, PostgreSQL, SQL Server) and transport layers (Kafka, RabbitMQ refactoring). The team also modernized the codebase by removing legacy abstractions, cleaning up samples, and upgrading to .NET 10.

2022–2023 · core infrastructure and in-memory implementation

This period focused on establishing the foundational architecture for the OpenSleigh framework, introducing core saga management, dependency injection, and the outbox pattern for reliable messaging. Significant effort was directed toward implementing in-memory persistence and transport layers to support lightweight testing and development scenarios. The work was complemented by comprehensive end-to-end and integration tests covering various saga patterns and database providers.

2025–2026 · saga state reporting and query API

This period focused on implementing a comprehensive saga state reporting system, introducing a new RESTful API for querying and filtering saga instances. The work included adding the core query interfaces, in-memory and SQL-based implementations, and extensive unit tests to validate the functionality. Additionally, sample applications were created to demonstrate the new reporting capabilities alongside existing microservices and Blazor integration features.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 3 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 6c5ea27d1d — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
