cua vs tachyon
cua: Cua is an open-source platform designed for building, benchmarking, and deploying AI agents capable of interacting with any computer. It provides isolated, self-hostable sandboxes using technologies like Docker, QEMU, and Apple Vz for agentic UI automation and secure code execution.; tachyon: Tachyon MCP is a Java 21+ server runtime that implements the Model Context Protocol, enabling the creation of robust AI agent servers with ease. It supports both synchronous Java and coroutine-first Kotlin handlers, abstracting away complex networking and threading details.

TL;DR
cuaLLM Infra · ★ 30.7k
When to choose:
- You are building Computer-Use agents and need robust, self-hostable isolated desktop/VM sandboxes (Docker, QEMU, Apple Vz).
- You need native app operating drivers, standardized benchmarking harnesses, and secure isolation for autonomous agent task execution.
When to skip:
- You only need simple UI macros on your personal physical machine (Windows-MCP or local desktop helpers are easier).
- Your agents interact solely via text APIs, shell commands, or databases and have no need for a virtual graphical desktop.
