Cua is an open-source infrastructure toolkit for building, benchmarking, and deploying computer-use agents. It provides a unified environment where AI agents can control full desktops across macOS, Linux, and Windows — without stealing the user's cursor or disrupting their workflow. The project ships four components: Cua Driver (background automation for macOS apps), Cua Sandbox (a unified API for VM and container control), CuaBot (multi-agent CLI with native window integration), and Cua-Bench (a benchmark suite compatible with OSWorld and ScreenSpot). Lume, a VM manager optimized for Apple Silicon, rounds out the toolkit. With 15,000+ stars and an MIT license, Cua is quickly becoming the de facto standard for teams building autonomous computer-use pipelines. As agents graduate from chat to "just do the thing," infrastructure like Cua becomes load-bearing.

LiteRT-LM is Google AI Edge's production-grade open-source inference framework for running large language models directly on edge devices — Android phones, iPhones, web browsers via WebAssembly, and IoT hardware. It powers the on-device GenAI features in Chrome, Chromebook Plus, and Pixel Watch that Google launched alongside Gemma 4. The framework supports a wide model zoo including Gemma, Llama, Phi-4, and Qwen, with quantization pipelines that fit models onto hardware as constrained as a wearable. It also supports function calling and tool use, enabling lightweight agentic workflows without a cloud round-trip. A JavaScript API makes browser integration straightforward for web developers. LiteRT-LM represents Google's answer to Apple Intelligence's on-device approach — an open, cross-platform runtime rather than a proprietary stack. The fact that it's open-sourced means any developer can ship private, offline AI features without touching Google's servers, which matters enormously for healthcare, finance, and enterprise applications.
Reviewer scorecard
“Cua solves the hardest part of computer-use agents — getting a stable, reproducible environment that doesn't fight your OS. The background automation mode alone is worth it for devs building macOS agents. 15k stars in a short window is a strong signal.”
“A unified inference runtime across Android, iOS, browser, and IoT with function calling support is exactly what the edge AI ecosystem has been missing. The WebAssembly path alone opens up private on-device AI in any browser without installing anything. Ship this immediately.”
“Computer-use agents are still fragile — they miss UI state changes, struggle with dynamic content, and hallucinate element positions. Cua gives you infrastructure, not reliability. Until benchmark scores improve on diverse real-world tasks, this is a research toy with impressive packaging.”
“Edge inference is still severely constrained — even quantized Gemma 3B on a phone gives you a noticeably worse experience than cloud APIs. Google's history with edge AI frameworks is also mixed: TensorFlow Lite, ML Kit, MediaPipe all launched with fanfare and then got inconsistent maintenance.”
“Every agentic workflow that touches a UI needs something like Cua. As models improve at visual understanding and cursor control, this infrastructure layer will be what production computer-use runs on. It's early, but it's exactly the right early.”
“This is infrastructure for the next decade. When models run on-device with no latency and no data leaving the device, entirely new categories of ambient, private AI become possible. LiteRT-LM is the missing runtime layer for that world — and Google open-sourcing it means the ecosystem builds around it rather than around Apple.”
“If you're building an AI that can use Figma, Photoshop, or any creative tool on your behalf, Cua is the missing scaffolding. The benchmarking suite means you can actually measure how well your agent handles design tasks — not just hope.”
“Offline AI for creative apps is a game-changer — imagine Procreate or Figma with on-device generative features that work on a plane. The browser WebAssembly support means I can prototype these ideas without an app store or backend. Very excited about the creative possibilities here.”
