OpenRig is a multi-agent harness that orchestrates Claude Code, Codex, and Pi to work together as a coordinated team. It solves the problem of managing complex, long-term coding projects by delegating specialized tasks to different AI agents, tracking their work, and consolidating results. It's designed for developers and teams who need to tackle large-scale software projects that require sustained, collaborative effort over weeks or months.
Starnet is a local-first desktop application that lets you run and manage real AI agents that perform actual work. It solves the problem of opaque, cloud-dependent AI tools by giving you full control—you bring your own API keys and watch your crew execute tasks directly on your machine. It's built for developers and tinkerers who want a transparent, customizable, and visually engaging interface for their autonomous AI workflows.
holaOS is an open-source, all-in-one workspace for AI agents. It solves the problem of fragmented AI tools by letting you run any agent (like Claude Code or Codex) across your entire digital environment—100+ integrations, apps, browser, and files—with shared memory for seamless context. It's built for developers and teams who want to centralize their AI workflows, offering built-in models or the flexibility to bring your own keys.
RAGFlow is an open-source Retrieval-Augmented Generation engine that builds a superior context layer for AI agents. It solves the problem of unreliable AI outputs by combining high-precision hybrid search with a built-in data ingestion pipeline and unified agent orchestration. It is designed for enterprises across industries like finance, legal, and manufacturing that need to build accurate, context-aware AI applications and workflows.
