To isolate Electron dev instances across git worktrees, you use a Bash script-driven lifecycle that applies marker-based configuration via environment variables, keeping per-instance workspaces, config, and data directories separate to prevent cross-talk.

Dev instances cross-talk with production workspaces when they lack marker-based isolation via environment variables. Applying per-worktree workspace directories and isolated configuration prevents this interference.

Yes, you can manage multiple side-by-side dev apps with per-instance configuration on macOS. The lifecycle controls support build, launch, status, and stop commands across worktrees with robust guardrails.

The best way to manage the lifecycle of isolated dev instances is using the provided Bash script to execute build, launch, status, and stop commands, which tracks per-instance state and prevents cross-talk.

You should not use git worktrees for isolating dev instances if your project lacks support for marker-based environment variable configuration or if your workflow does not require side-by-side feature testing across multiple worktrees.
