CUA is an open-source infrastructure platform for building, testing, and deploying computer-use AI agents. It provides a unified Python SDK that lets agents take screenshots, click buttons, type text, and run shell commands across macOS, Linux, Windows, and Android — treating every OS as a consistent, programmable API surface. The project ships as several modular pieces: Cua Driver for background macOS app control without disrupting the user's session, Cua Sandbox for cross-platform virtual environments, CuaBot for multi-agent CLI orchestration integrated with Claude Code, and Cua-Bench for standardised benchmarking of agent performance across tasks. Lume adds full macOS and Linux virtualisation on Apple Silicon. With 16,400 GitHub stars, 482 releases, and a fresh driver update shipping in May 2026, CUA has become a de facto foundation for teams building computer-use applications. The MIT license and thorough documentation at cua.ai make it accessible for both academic research and production deployments where GUI automation via API simply isn't available.

Gemini CLI brings Google's Gemini 2.5 Pro directly into your terminal as a local, open-source AI agent. Released under Apache 2.0, it operates in a ReAct (Reason + Act) loop — meaning it thinks, acts, observes results, and iterates until the task is done. It connects to local and remote MCP servers, supports a GEMINI.md system prompt file for project-specific context, and handles everything from coding to research to task management. The free tier is unusually generous: 60 model requests per minute and 1,000 requests per day at no cost with just a personal Google account. That's 1 million token context on Gemini 2.5 Pro, for free, at scale. For teams that have been paying for Claude Code or GitHub Copilot just to get terminal AI access, this changes the math significantly. Google open-sourced the tool in response to growing momentum from Claude Code and OpenAI's Codex CLI — but the free tier generosity is the real differentiator. Whether Google can maintain those quotas as usage scales is the open question, but the initial offering is hard to ignore.
Reviewer scorecard
“The cross-platform API abstraction is genuinely well-designed — the same agent code that drives a Linux terminal works on macOS GUI apps without modification. CuaBot with Claude Code is a surprisingly capable local autonomous agent stack for tasks that have no API.”
“1,000 free requests/day with 1M context on Gemini 2.5 Pro is genuinely crazy good. For hobby projects, side-gigs, and open source work, Gemini CLI just eliminated the cost barrier for terminal AI. Install it alongside Claude Code and let them compete for your prompts.”
“Computer-use agents are still brittle against real-world UI variance. CUA solves the infrastructure problem well but doesn't solve the underlying reliability problem — agents still fail on unexpected popups, resolution changes, or app version updates. Infrastructure is necessary but not sufficient.”
“Free tiers in AI are subsidized experiments, not business models. When Google inevitably throttles or monetizes Gemini CLI, you'll have built workflows around it. And Gemini 2.5 Pro, while good, still trails Claude Sonnet on complex multi-step coding tasks where it counts.”
“CUA is load-bearing infrastructure for the era where software agents don't call APIs — they use computers the way humans do. Every major enterprise workflow that can't be API-ified becomes automatable once agents can reliably see and interact with a screen.”
“The terminal is the new battleground for AI adoption among developers. Gemini CLI, Claude Code, and OpenAI Codex CLI launching within months of each other signals that the command line is where AI earns developer trust — and whoever wins there wins the next decade of enterprise tooling.”
“Automating Figma, Notion, or browser-based tools that have no API is genuinely exciting from a creative workflow standpoint. Waiting eagerly for the macOS agent reliability to mature enough to handle complex creative app workflows without hand-holding.”
“For content workflows that mix code with research — scraping, generating, transforming — Gemini CLI's 1M context window is a game-changer. I can feed it an entire book and ask it to extract structured data. The free tier makes it worth building entire pipelines around.”
