Ntfy：一款开源的手机推送通知服务
Ntfy 的核心设计思路是「推送即 HTTP」。用户只需向 ntfy.sh 服务器发送一个 POST 请求，内容就会实时推送到订阅了相应主题的手机上。这种极简架构使其可以轻松集成到 shell 脚本、cron 任务、CI/CD 流水线或任何能发起 HTTP 请求的环境中。例如，curl -d "备份完成" ntfy.sh/mytopic 一条命令即可完成推送，无需 SDK 或复杂配置。
从工程角度看，Ntfy 提供了自托管选项，用户可以在自己的服务器上部署完整实例，数据不经过第三方。它支持消息优先级、标签、延迟投递、附件以及基于 WebSocket 的实时订阅。与商业推送服务相比，Ntfy 的优势在于零依赖、零成本、数据可控；劣势则是缺少 FCM 的系统级通道优化，在 Android 上需要常驻前台服务或依赖 UnifiedPush 协议来维持连接，可能对电池续航有一定影响。原文未提供具体的性能基准数据。
在同类开源推送方案中，Ntfy 与 Gotify 定位相似，但 Ntfy 的 HTTP-first 设计使其更易于脚本化集成，且官方提供免费的公共实例（ntfy.sh），降低了上手门槛。对于开发者而言，这类工具填补了「服务器事件到手机通知」之间的轻量级通道空白，尤其适合个人项目、家庭实验室和自托管爱好者群体。

Push notifications made easy
ntfy (pronounced notify) is a simple HTTP-based pub-sub notification service. It allows you to send notifications to your phone or desktop via scripts from any computer, and/or using a REST API. It's infinitely flexible, and 100% free software.

Send push notifications from your app or script
Publishing messages can be done via PUT or POST. Topics are created on the fly by subscribing or publishing to them. If you use ntfy without sign-up, the topic is essentially a password, so pick something that's not easily guessable. If you purchase ntfy Pro, you can reserve topic names instead.
curl ntfy CLI JS Go PS Python curl \ -d "Backup successful 😀" \ ntfy.sh/mytopic
Receive notifications on your phone
Subscribe to a topic and receive notifications, with different priorities, attachments, action buttons, tags & emojis, and even for automation.

You can use the web app to subscribe to topics as well. If you do, notifications will pop up as desktop notifications. Simply type in the topic name and click the Subscribe button. The browser will keep a connection open and listen for incoming notifications.

Integrate with your favorite tools
Publishing messages is just a HTTP request, so pretty much everything under the sun can integrate with ntfy.
