Evidence-linked multi-model database. Documents, graphs and vector search in one Rust binary. Store documents, connect them with typed relationships, and query across graph, full-text and vector search - with links back to supporting source text.

IronCrew is a lightweight, high-performance framework for orchestrating multi-agent AI workflows. Write your agents, tasks, and logic in Lua — IronCrew handles parallel execution, tool calling, memory, and inter-agent communication in a single self-contained binary.

A lightweight, high-performance workflow engine built in Rust with Lua scripting. The open-source alternative to n8n, Airflow, and Prefect that ships as a single binary without a Python, Node.js, or container runtime.
IronFlow is a DAG-based workflow orchestration engine designed for CI/CD pipelines, data processing, ETL jobs, API integrations, document extraction, and task automation. Define workflows in simple Lua scripts — a language with only ~20 keywords — and run them on a sandboxed, async Rust runtime with parallel step execution, retry logic, conditional routing, and a built-in REST API.
