Kelvin Code spins up iOS simulator capsules in seconds, no VM. You watch live and inspect the session evidence.
Disposable devices by cloning, with no VM or 100 GB download. We measured 3.3 s to clone and 16.1 s until the capsule is usable.
Claude, Codex or Cursor drive the device while you watch — Observe, Act, Verify, with every action on the record.
Every session seals captures, steps and a verdict in a package. You can inspect what happened and check the files' integrity.
Kelvin Code is a developer tool for macOS. It installs and runs your mobile app on an iOS simulator inside your Mac, in disposable capsules and without a VM. It is for the people who build mobile apps and for the people who need to see the app working: engineering, product, design and QA.
The simulator executes on your Mac. When you connect Kelvin Code Cloud, live frames and session evidence cross the network for authorized people; the tested app and run artifacts may also be stored in the Cloud.
For shared sessions, you enroll the Mac in Kelvin Code Cloud, currently in closed alpha by invitation. Kelvin Code does not request access to your Drive, Gmail, Calendar, contacts or repositories.
Kelvin connects people, agents and real apps to discover, build and prove software.
