What it is
A webhook that turns into a push notification. Point a script, a server or a cron job at your Chegou URL and the message lands on your devices, right away or at a time you choose.
There is no account to create. The API and the mobile app are both open source.

How it works
Immediate: webhook → validate → target devices → APNs / FCM → your phone
Scheduled: webhook → validate → encrypt → SQLite → BullMQ / Redis → APNs / FCM
Every request is checked against a Zod schema with a 4 KB payload limit. Scheduled payloads are encrypted and stored in SQLite, and BullMQ keeps each job in Redis until it is due.
Details
- The webhook URL is the identity. Its secret part is stored as an Argon2 hash.
- Device management is signed with Ed25519 inside a 30-second window.
- Channels group devices and appear the first time you use them, up to 50.
- Scheduled payloads are encrypted at rest with AES-256-GCM and a fresh IV per message.
- Rate limits per IP: 30 webhook calls and 5 management calls a minute.
