Description
I’ve been tinkering with what a “multi-agent IDE” should look like if your day-to-day workflow is mostly in terminal (Claude Code, OpenAI Codex, etc.). The more I played with it, the more it collapsed into three fundamentals:* A good TUI: Terminal is the center stage, with other stuff (CodeEdit, Diff, Review) baked on the side. I don’t like piping Agent’s output through some electron wrapper, here you get to run CC/Codex/Droid/Amp/etc directly.* Isolation: agents shouldn’t step on each other’s toes. The simplest primitive I’ve found is Git worktrees. It is not as isolated nor heavy as containers/vms, but it is the next best thing for working locally. Each agent gets its own working directory and their own snapshot of the repo. Git worktree requires CLI kung-fu, but agentastic simplifies it through some nice GUI and keyboard shortcuts for easy creation/switching/etc.* An excellent terminal: I couldn’t get comfortable with xterm.js (Code/Cursor/Conductor/etc), and i loved Ghostty, it is fast, pretty, and feels right. So naturally the whole experience is built around Ghostty (There is also SwiftTerm as an alternative option).Agentastic.dev is a native mac IDE, built around the workflow of “one task = one worktree = one terminal session” as the default. You spin up multiple worktrees (branches) and run different agents in parallel, each with its own clean working directory and terminal session and codeedit, then review and merge when you’re ready.We’ve been dogfooding it to build http://agentastic.dev itself and agentastic.com (coming soon), and it’s noticeably improved our productivity. https://pasteboard.co/xg1YOsk5MIn9.pngIt’s early and still rough in places. I’d love feedback from people who use worktrees heavily or run multiple coding agents:- What would you want from a multi-agent IDE that you can’t get from a terminal + tmux?- What’s missing / annoying in your current worktree workflow?

Could you build this?
Partial Scripting Git worktrees and orchestrating agents is simple, but engineering a high-performance native macOS IDE with embedded terminal rendering and multi-process management requires deep systems and AppKit knowledge.
What it would actually take: The architecture requires a native macOS application (Swift/AppKit) integrating an embedded terminal emulator engine (like Ghostty or SwiftTerm), an editor core, and a custom Git worktree supervisor. The hard parts are low-latency PTY multiplexing across dozens of concurrent background processes, managing complex Git state reconciliation, and rendering real-time diffs smoothly. It requires seasoned native macOS systems programming and terminal emulation expertise.
Discussion
20 comments analyzed.
Competitors mentioned: Branchbox, Claude Code, Codex, Droid, Colima + Cloudflared
Concerns raised: Manual QA is the bottleneck; can't test faster than agents produce output, Agents need sandboxing to prevent system damage while allowing full stack access, macOS version requirement mismatch (docs say 13+, Info.plist requires 14.0), Large context size hurts performance with multiple parallel agents, Agents take 10 minutes to 2+ hours per task
Feature requests: Setup and shutdown scripts for worktree lifecycle management, Container/VM isolation with Firecracker or similar, Devcontainer support, Domain name input during setup (with autogeneration fallback), Environment variable expansion for branch-specific configuration
