Public source.
The client source is public. The licence of every component is available in the app and here.
No ads. No tracking.
No ad SDK, no analytics, no fingerprinting. Apple's own crash reports only if you opted in with Apple.
Your library stays yours.
Local play works offline. iCloud sync uses your own private Apple storage. Optional Relay Sync plans are separate.
The code
Source repository: github.com/relayemu/client. The client builds independently with Xcode. Build and contribution instructions are in the repository.
The emulators inside
Relay does not write emulators; it stands on excellent ones and says so. Each core ships at an exact, pinned revision under its own licence:
- melonDS 1.1 — GPL-3.0-or-later — nds
- Mesen 2 2.1.1 — GPL-3.0 — nes, snes, sms, gg, pce, ws, wsc
- mGBA 0.10.3+provenance — MPL-2.0 — gb, gbc, gba
- PCSX-ReARMed r26-da2cb8e — GPL-2.0-or-later — ps1
The name and the mark
The client is free software; its identity is protected. The Relay name, the Baton mark and the icon belong to the project so that "Relay" always means Relay. Client forks are welcome under their own name. Trademark policy
Your iCloud
Library, save, progress and opt-in game-file continuity use your private iCloud and stay free. You do not need a Relay Account or a Relay Sync plan to use iCloud.
