Introduction to the FlowSynx​

FlowSynx is a flexible, plugin-driven, cross-platform .NET-based DAG workflow orchestration system, designed to automate, scale, and manage complex data workflows across cloud and on-premises environments. Written in C# and built on .NET, FlowSynx bridges the gap between low-code accessibility and full-code extensibility, empowering developers and operations teams to define and execute powerful, declarative workflows in a simple, consistent, and maintainable way.

With its modular plugin architecture and native C# SDK, FlowSynx supports seamless integration with external systems, custom business logic, cloud storage providers, databases, APIs, and more—allowing users to extend functionality without modifying the core engine. Workflows are represented as JSON-based DAGs (Directed Acyclic Graphs), enabling precise control over execution order, dependencies, retries & error handling, and conditional logic.

FlowSynx features:

  • .NET-native, cross-platform execution, supporting Windows, Linux, macOS, and containerized deployments (Docker)
  • Dynamic plugin loading and versioning using C# assemblies
  • Event-driven triggers, human-in-the-loop tasks, and full audit logging
  • Integrated configuration, logging, and auditing, stored in a secure and pluggable backend
  • Role-based access control and per-user security settings
  • Support for hybrid deployments, enabling workflows to span both local infrastructure and remote cloud services
  • Full support for retry policies, failure handling, and stateful tracking of workflow execution

Whether you’re automating file transfers, orchestrating machine learning pipelines, syncing distributed systems, or building robust ETL jobs, FlowSynx’s C# API and .NET foundation offer a scalable, extensible platform to accelerate workflow development and reduce operational complexity—without sacrificing control.

Architecture overview​

Intraction tools​

  • CLI Interface: Command-line tools written in .NET for interacting with FlowSynx, enabling workflow management and execution from terminals.
  • REST API Gateway: Provides secure, HTTP/HTTPS RESTful APIs to integrate with external systems, allowing remote workflow control and status querying.
  • SDK (Library): Developer-friendly .NET libraries exposing FlowSynx functionalities programmatically, enabling custom applications to embed or automate workflow operations.
  • UI-Based Console Management: Browser-based interface for real-time monitoring and administration of workflows and system settings, built with Blazor and .NET backend.

FlowSynx Core​

  • Workflow Orchestrator: Loads and executes workflows defined as JSON DAGs with native C# execution.
  • Plugin Manager: Dynamically loads C# plugins as assemblies and maintains a plugin marketplace/registry.
  • Security & Authentication: Handles authentication and authorization for both REST API and CLI access.
  • Logging & Auditing: Tracks workflow execution, plugin activity, and audit trails.
  • Trigger Engine: Listens for external events or schedules workflows to start based on timers, webhooks, or system signals.
  • Error handling: Built-in support for task retries, timeouts, and fallbacks ensures reliable execution even in unstable environments. Custom retry strategies can be defined per task.

Execution environments​

  • Deployment & Execution Environments: Supports flexible deployment models from standalone desktop/server installs to cloud containerized orchestration, with full cross-platform .NET runtime compatibility.
