Choose how you play Krypton
Krypton supports browser play, native desktop clients, and iPhone and iPad access through external TestFlight within one connected game ecosystem.
Play in your browser
Open Krypton through a supported modern browser without installing a desktop client.
Use a native desktop client
Install the supported Krypton desktop client for a dedicated game window and launcher-managed client updates.
Join on iPhone and iPad
Eligible testers can request access to the iPhone beta through external TestFlight. Krypton promotes the beta for testing on iPhone and iPad, while device compatibility remains subject to the current TestFlight build.
Keep one account
Your Krypton account and game progress belong to the shared ecosystem rather than a single device.
