The fastest way to run agents in parallel
Cornercase is a high-performance terminal multiplexer designed specifically for developers working with AI-powered agents. It streamlines the process of managing multiple coding agents—such as Claude Code, Codex, or Gemini—by turning issues from platforms like GitHub, GitLab, Jira, and others into independently running agents. Each agent operates within its own git worktree and terminal tab, enabling seamless parallel workflows and real-time review. Its ultra-fast launch time of just 34 milliseconds and minimal RAM usage (53 MB) make it an efficient choice for developers seeking to optimize their productivity. The tool's user-friendly interface allows users to monitor agent activity, review code diffs as they are generated, and manage agents effortlessly, whether on desktop or mobile, including Telegram. Being open source and compatible with Linux and macOS, Cornercase offers a flexible, customizable environment tailored for modern development teams focused on AI integration and issue management.
