Building a self-hosted, AI-native workflow engine in Rust (180 node types, no SDK bloat)

Short summary

Trigix is an open-source, self-hosted workflow automation engine written in Rust with ~180 node types and support for local AI models. The author shares architectural decisions around keeping dependencies lightweight (pure-Rust SSH, custom SigV4 implementation) and using standardized interfaces (OpenAI-compatible LLM wire format) to avoid SDK bloat. Available on GitHub with Docker Compose and Helm deployment options.

• •Self-hosted Rust workflow engine with 180 node types designed to minimize SDK dependencies
• •Uses pure-Rust implementations (SSH, SigV4) and caller-supplied tokens to avoid heavyweight provider SDKs
• •Supports local AI models via OpenAI-compatible format; includes Docker Compose and Helm deployment
