PushMate

PushMate is a macOS‑native editor for Apple Push Notification Service (APNS) payloads. It provides a text‑based interface where developers can compose JSON payloads and receive immediate validation against Apple’s format rules, highlighting errors as they type. The tool includes autocomplete for known payload keys, helping to construct correct messages without memorising the full schema.

Designed for iOS developers who need to test and debug push notifications, PushMate integrates with macOS features such as autosave, versioning, and dark‑mode support. Its lightweight footprint makes it fast to launch and use alongside other development tools, and the live error checking reduces the trial‑and‑error cycle when refining notification content.

The application is distributed through the Mac App Store, runs on recent macOS releases, and focuses on a minimal, unobtrusive workflow that lets users edit and validate APNS JSON without additional overhead.
