 "title": "Run several app branches side by side without port clashes",
 "page_title": "How to run several app branches side by side without port clashes with Simfleet",
 "summary": "Give each branch its own slim device, worktree, and leased Metro port from one dashboard.",
 "who": "A React Native developer who needs to test three or four feature branches at the same time and is losing time to simulators and Metro port 8081 conflicts.",
 "problem": "Each simulator can take several GB, and Metro servers fight over the same port when several branches run together.",
 "outcome": "Each branch runs as a lane on its own device and its own leased Metro port, and the dashboard shows every device with its state and memory footprint.",
 "steps": [
  "`bun add -g simfleet`",
  "`cd path/to/your-app`",
  "`simfleet init`",
  "`simfleet serve`",
  "`simfleet sim boot`",
  "`simfleet lane start \"$PWD\" development debug` (inferred, check the README)",
  "`simfleet lane launch`"
 ],
 "agent_prompt": "Using the simfleet repo (entropyconquers/simfleet), run `simfleet lane start \"$PWD\" development debug` inside <path-to-app> and then `simfleet lane launch`. Expected output: a lane with a leased Metro port and the dev client opened on that port. Verify with `simfleet ports` that the leased port appears in the list.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "1 hour",
 "basis": "readme",
 "caveat": "Simfleet trusts the local machine: its API binds to 127.0.0.1 with no authentication, and it needs the Xcode and Android tooling installed before any device can boot.",
