serve-sim
The `npx serve` of Apple Simulators.
The Lens
By Erik Loyd, SaaS CEO and former COO/CFO of an AWS Premier Partner.
Updated Jul 2026
serve-sim streams an iOS Simulator to a browser. You get the framebuffer, gestures, keyboard input, and logs over the network or piped to AI coding tools like Cursor or Claude Desktop. Built by Evan Bacon (Expo). Apache-2.0.
Run npx serve-sim and you have a preview server on localhost:3200. Multiple booted simulators work in parallel, daemon mode runs it in the background, and there is middleware for embedding it inside your existing dev server.
Solo: easy way to share what you are building with a teammate over Tailscale. Small teams testing iOS apps: stream the simulator to AI agents for visual feedback during development. Teams building infra: this is the foundation if you want to host simulators centrally instead of tying every test session to one engineer's laptop.
The catch is macOS. Apple's simulator only runs on Apple hardware, so this serves what you have, it does not conjure a simulator on Linux.
Free vs Self-Hosted vs Paid
fully freeFree tier: Full tool, Apache-2.0.
Self-hosted: All you have. Runs on the Mac that already runs the simulator.
Paid: None.
Free and Apache-2.0. Your only cost is the Mac you already need to run a simulator.
