Open-Source Claude Cowork
Multica: A local-first desktop client for Claude Code, Codex & OpenCode agents. Visual interface, plugin-powered workflows, full data privacy.
A native desktop client that brings the power of programming agents to everyone through a visual interface.
Fully local-first, with simultaneous support for Claude Code, Codex, and the open-source OpenCode.
Multica aims to become the middle layer between coding agents and end users — somewhat similar to the Obsidian model — where everyone can customize it via plugins according to their own workflow.
Multica + development-related plugins → Cursor / Lovable / Conductor
Multica + design-related plugins → Lovart
Multica + research-related plugins → NotebookLM
Multica handles the middle-layer responsibilities:
UI/UX interaction
VM & Sandbox
Multi-agent & LLM orchestration and scheduling
Plugin store
