cornercase
cornercase is a fast terminal multiplexer for coding agents that runs them in parallel with individual git worktrees.
Cornercase is a fast terminal multiplexer designed specifically for running coding agents in parallel. Each agent receives its own dedicated git worktree, branch, folder, and tab so that multiple tasks do not interfere with one another. Users can pick issues directly from GitHub, GitLab, Linear, Jira, Plane, or Shortcut to automatically generate worktrees and start prompts. A persistent server owns the shells, meaning agents, tests, and development servers continue running even if the window is closed, the laptop is shut, or Wi-Fi drops. The interface includes real-time diff viewing, status tracking for models and context limits, file browsing, search capabilities, and notifications sent via Telegram, Discord, or terminal alerts.
