Cua is an open-source platform for building, running, and benchmarking AI agents that autonomously control computer interfaces. It provides a unified sandbox API that lets agents capture screenshots, move the mouse, type, and interact with native applications across Linux containers, VMs, macOS, Windows, and Android — all through a single consistent interface regardless of platform. The toolkit ships five components: Cua Sandbox (cross-platform agent execution), Cua Driver (background macOS automation that doesn't steal focus), Lume (macOS/Linux VM management on Apple Silicon via Apple's Virtualization Framework), CuaBot (CLI for running Claude Code and OpenClaw agents inside isolated sandboxes with native window rendering), and Cua-Bench (evaluation suite covering OSWorld, ScreenSpot, and Windows Arena benchmarks with trajectory export for training datasets). With 14.2k GitHub stars and 465 releases, Cua has quietly become the default infrastructure layer for developers building serious computer-use agents. It's trending again in April 2026 as the launch of Cursor 3's background agents and OpenAI's operator-style tooling sends developers looking for local, controllable sandboxes that don't phone home.

Trigger.dev provides background jobs, scheduled tasks, and event-driven workflows with a TypeScript-first SDK. Handles retries, concurrency, and long-running tasks.
Reviewer scorecard
“Cua is the plumbing that makes computer-use agents actually work in production. The fact that Cua Driver handles background macOS automation without stealing focus is the detail that separates a demo from something you can ship. 465 releases means this is battle-tested infrastructure, not a weekend project.”
“TypeScript-native background jobs with great DX. The dashboard for monitoring and debugging jobs is excellent.”
“Computer-use agents are still fragile — UI changes in target apps silently break automation in ways that are hard to detect. The benchmark suite evaluates on static tasks, not real-world drift. And running full VMs per agent session has serious cost implications at scale. The infra is solid; the fundamental computer-use problem isn't solved.”
“Solves the 'I need a queue but don't want to manage infrastructure' problem elegantly.”
“Cross-platform sandboxed execution is the prerequisite for every autonomous agent use case that isn't purely API-based. Cua normalizes the surface that agents operate on — once that layer stabilizes, the agents themselves can improve rapidly without infrastructure churn. This is foundational scaffolding for the agent era.”
“Background job infrastructure is moving to managed platforms. Trigger.dev has the best DX in this space.”
“I used Cua to build an agent that fills in repetitive design tool tasks — font checks, asset exports, spacing audits. The background automation on macOS is surprisingly clean. It's opened up automation use cases I assumed required paid SaaS.”
