Run a flock of Claude Code (or other agents) in one window.
Free macOS app for running multiple Claude Code sessions side by side. Split panes, 7 themes, command palette, agent kanban board, AI memory, prompt compression, usage tracking, and broadcast mode. Native Swift/AppKit. Signed and notarized.
Hey everyone. I'm Brandon, and I built Flock because I was tired of the options for running Claude Code.
Most terminal apps look like they were designed in 2005. VS Code and Cursor work, but opening a full IDE just to run terminal sessions felt wrong. And no matter what I used, running multiple Claude Code sessions meant juggling tabs and losing track of what each agent was doing.
So I built what I actually wanted: a native macOS app that looks good, runs fast, and is purpose-built for parallel AI coding sessions. Each pane shows live activity indicators, token usage, and status. You see everything at a glance.
What makes it different: - Split panes with auto-tiling (Cmd+D / Cmd+Shift+D) - 7 hand-picked themes from light to dark - Command palette (Cmd+K) for fast navigation - Agent mode with a kanban board for parallel tasks - Wren compression that cuts token usage by up to 60% - Built-in usage tracking so you never hit your limit by surprise - Broadcast mode to type into all panes at once
It's free, open source, and native Swift/AppKit. No Electron.
Would love your feedback. What features would make this more useful for your workflow?
