What is apprise?

Apprise lets you send push notifications to almost any messaging service, Telegram, Discord, Slack, email, SMS, and dozens more, all from a single tool. Instead of writing separate code or finding a separate tool for each platform you want to notify, you write one notification once and Apprise handles delivering it everywhere. The way it works is straightforward. You tell Apprise which services to send to using simple URLs that contain your credentials for each platform, for example, a Discord webhook URL or a Telegram bot token. Then you give it a message, and it fires it off to all of those services at once. Messages go out asynchronously, meaning it doesn't wait for one service to finish before starting on the next, which keeps things fast. It can also handle images and file attachments for services that support them. This is built for two main audiences. Developers who want to add notifications to their app no longer need to research and integrate a dozen different APIs, they add one library and get access to nearly every notification service out there. System administrators and DevOps folks can use the command-line tool to send alerts when servers go down, deployments finish, or anything else needs attention, without hunting for the right tool for each platform. A few things stand out. The project supports an enormous list of services, well over 50 at this point, covering productivity apps, SMS, email, desktop notifications, and custom hooks. You can also use configuration files to define your notification targets once and reuse them, so you're not repeating setup every time. It's written in Python and designed to be lightweight. The main tradeoff is that you're relying on a single library to keep up with every notification service's API, which changes over time. But that's also the point, instead of you tracking those changes across dozens of services, the project does it for you.
