Agent CLI Config Isolation Manager for macOS
A lightweight macOS utility that creates isolated HOME environments for AI agent CLIs so multiple agents can run simultaneously without their config files stomping each other. Unlike general multi-instance tools, this focuses specifically on the CLI agent workflow with pre-configured isolation profiles for popular agents.
Why this matters
You are a developer running multiple AI agent CLIs on your Mac — maybe a coding assistant, a research agent, and an automation script. Each one dumps its configuration files into your home directory, and when they run simultaneously they overwrite each other's settings. The only workaround you have found is creating separate macOS user accounts and switching between them, which breaks your normal workflow for opening files and links. You feel like you are solving this problem in the most primitive way possible. You need a tool that gives each agent its own isolated config space without forcing you to abandon your primary macOS user environment.
- · Built for Developers and power users who run multiple AI agent CLIs (coding assistants, automation agents) simultaneously on macOS and suffer from config file conflicts in their home directory.
- · Most likely monetization: freemium.

MVP Scope · 1–2 weeks
- Build a shell wrapper script that accepts a CLI command, creates a temporary HOME directory, and launches the command with HOME overridden to that directory
- Create a JSON config format for defining agent isolation profiles (agent name, expected config paths, env vars)
- Write isolation profiles for 3 popular AI agent CLIs by researching their config file locations
- Build a simple CLI interface: 'isolate run <agent-name>' that uses the corresponding profile
- Test with 2-3 real AI agent CLIs to verify config separation works and agents still function correctly
- Add a basic macOS menu bar app (SwiftUI) that lists configured agents and lets you launch isolated instances with one click
- Implement config state management so isolated configs persist between runs (not just ephemeral)
- Add file and link passthrough so isolated agents can still open files in your default editors and links in your default browser
- Create a simple onboarding flow that detects installed AI agent CLIs and suggests pre-built profiles
- Set up a landing page with download link and launch on HN and relevant dev communities
Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1macOS may enforce sandbox or SIP restrictions that prevent a third-party tool from reliably overriding HOME for arbitrary child processes, especially for CLIs launched from Terminal rather than from the tool's own GUI — this is the single biggest technical risk and the original commenters explicitly questioned whether it works.
- 2AI agent CLI tools may add native multi-profile or multi-environment support within 6-12 months as this is a known pain point, making a third-party solution redundant. Large well-funded agent projects have the resources to solve this natively.
- 3The market may be too narrow — developers who run 2+ AI agent CLIs simultaneously on macOS is a small subset of an already niche audience, and many may tolerate the separate-user-account workaround rather than paying for a dedicated tool.
Evidence Summary
How AI synthesized this insight — no verbatim quotes
Approximately 2-3 commenters zeroed in on the HOME override as the most valuable feature, with one explicitly describing running multiple agent CLIs whose configs conflict in the home directory. That commenter revealed they currently use separate macOS user accounts as a workaround, expressing visible frustration with the approach. Another commenter raised concerns about whether macOS sandboxing permits the necessary environment variable manipulation for child processes. No commenter discussed price, but the severity of the workaround signals a real willingness to pay.
