Such a great, simple and reliable service. Using it for all sorts of things: nostr push notifications, link sharing between devices, grafana alert notifications.

Been running ntfy in my homelab for several years. Always works great!

  Incredibly useful to give any app the ability to send you a notification with a single line of code or shell. Only one minor caveat for self-hosted iOS users - content of the messages come from your server, but the trigger still comes from ntfy.sh server.
  - lxgr 2mo ago
    You can "install" the PWA on iOS by adding it to your home screen, then your ntfy instance can use APNs directly (via Web Push)!

      Very nice. Thank you. I am not super concerned but I know people here tend to be.

I wonder whats the difference between permisions do giant apps like whatsapp, instagram have for notification service. cause they seem like perfectly integrated themselves into this, while ntfy has to pose itself as battery consuming application I'm planning to using ntfy for notifications like bitwarden vault backups, if apps are updated.
- NetMageSCW 2mo ago
  Probably not permissions so much as proper implementation of push messaging for mobile. Apple created a push message infrastructure and Google followed that allows their messaging infrastructure already running on the phone to multiplex messages for multiple apps without needing additional power for listening. I use Pushover for email push notifications- it doesn’t have a subscription and using the proper APIs.
- lxgr 2mo ago
  What do you mean by "battery consuming application"? At least the PWA of ntfy can use Web Push, which uses your browser's existing push notification service and should not consume any additional battery.
- edoceo 2mo ago
  I've been using ntfy for ages. Doesn't chew my battery too much. Chrome, mail and mattermost are my top. Ntfy gets less than 30 notifications per day.
- robgibbons 2mo ago
  FCM (Firebase Cloud Messaging), and Apple's own APN (Apple Push Notifications) work as a single OS level service, and they are multiplexed so that many different apps can route through them with a single connection, even waking your phone/watch from sleep. There are open/de-Googled alternatives like UnifiedPush, but they're not integrated at the OS layer (they run as a background worker thread), and can't match the battery efficiency or sleep-wake capabilities of those built into the OS/low-level networking layer.
- binwiederhier 2mo ago
  If you use ntfy.sh and don't use instant delivery, ntfy uses Google's FCM for delivery, which is what everyone else does. It doesn't require a foreground service and has no battery impact. ntfy offers you additional options with instant delivery or the selfhostable server. That requires a server connection and does impact battery a little. On my phone it doesn't show up in the list it's so low, but others have reported more consumption
weinzierl 2mo ago
There used to be pushed.co which was free and pretty good but it seems to have disappeared completely. Does anyone know what happened to them?
lone-cloud 2mo ago
I'm a privacy focused self hoster and ntfy was not good enough for me so I created Prism with an optional Android app: https://git.lonecloud.dev/lone-cloud/prism https://git.lonecloud.dev/lone-cloud/prism The difference: Your phone doesn't get notifications from your notification service directly, but from Mozilla which helps to hide your digital fingerprint of you using a separate notification provider like ntfy. Prism also allows Telegram or Signal to act as a notification distributor. In addition, I use Proton Mail which doesn't really allow custom notification services. Prism has a custom integration to work around that so your proton mail notifications don't have to touch google services.
- crtasm 2mo ago
  Interesting, how is it able to send via Mozilla? I did a quick search in the repo and the term isn't found.
  - lone-cloud 2mo ago
    The webpush endpoint registration is initiated from the client. The Android app can act as a client and it's the one that registers Mozilla's autopush service.
- grapemane 2mo ago
  In what ways is your digital fingerprint being monitored where your notification providers are being captured?
  - lone-cloud 2mo ago
    I meant that at the network level, should something be monitoring, your client would be making requests to a unique (ntfy) address that virtually nobody else ever uses. Requests to Mozilla are more crowd blended as it's quite popular already.
    - LeBit 2mo ago
      Aren’t the requests https? Or you mean you are trying to hide from a network where you are mitm attacked?

I've been using Gotify [1] for a very long time and have been quite happy with it. Basically no impact on battery life. For devs - there are mature libraries like shoutrr [2] and apprise [3] that let you support multiple notification systems with no extra work. 1. https://gotify.net/ https://gotify.net/ 2. https://shoutrrr.nickfedor.com/v0.17.0/ https://shoutrrr.nickfedor.com/v0.17.0/ 3. https://github.com/caronc/apprise https://github.com/caronc/apprise
- rahimnathwani 2mo ago
  Right, but if you use ntfy.sh you can get proper mobile push notifications (instead of keeping the app running and using long polling or websockets). If you use the public version of ntfy.sh then you don't need to do anything to set this up. If you self-host, you need your own Firebase Cloud Messaging (FCM) account and (for iOS) your own Apple Developer account so you can use APN.
  - oulipo 2mo ago
    Personally I use FCM (Firebase push notifications) with a Capacitor plugin for push notifications, it works decently
    - rahimnathwani 2mo ago
      I didn't know what you meant by Capacitor, but I now understand it's a modern replacement for Apache Cordova: https://capacitorjs.com/ https://capacitorjs.com/
      - oulipo 2mo ago
        Yes exactly, it's an easy way to build a web-based app and run it on iOS and Android, accessing the native API through a javascript bridge. There's also NativeScript in that space
  - subscribed 2mo ago
    Publicly hosted version is nearly useless if you'd like to use it to send notifications from your tiny workers/scripts/processes in the big datacentres - I have a minuscule worker in CF that needs to send one notification once every few days, and I *ALWAYS* get a 429. Always. So this is good maybe if you're using it to sent from your laptop to your phone.
dewey 2mo ago
Not Open Source but I’ve been using https://pushover.net/ https://pushover.net/ for this use case since forever. The website still looks the same as on the day I signed up for it probably more than 10 years ago. Never had an issue and using that in all my scripts or cron jobs.
- Vaslo 2mo ago
  I had all sorts of nfty notification to ios issues despite lots of trial and error and a bunch of AI tokens. I also moved to pushover.
  - subscribed 2mo ago
    I can't use it at all except for inconsequential notifications from my laptop (residential IP) or my phone (mobile IP).
- oulipo 2mo ago
  What's the advantage over, say, having a Telegram bot push you messages instead of notifications?
  - dewey 2mo ago
    The advantage is that I don’t have to use Telegram and Pushover can just be triggered by curl in any scripts I use.
    - loremm 2mo ago
      Not nitpicking but I have curl send telegram, it's not bad but I agree pushover looks nice I have it so it can send email, telegram, or twilio call depending on urgency
  - mbirth 2mo ago
    Notifications can carry metadata like specific alert sounds or priorities. High priorities will even break through silence modes of your phone. And you get a nice client with icons for each notification source, can filter by them, etc.
KetoManx64 2mo ago
Love this service! I use it to send commands and URLs between my devices. On Linux you can do `ntfy sub` and on android you can have Tasker react when a ntfy notification arrives based on its title and contents. So on just about all my devices I have a background script running that is subscribed to a "DeviceCommands" channel that checks if the Title of new messages contains the device hostname or not. If it does it triggers a script based on the contents of the body. E.g.: Title: Pixel8 Message: https://kagi.com https://kagi.com Will automatically send the URL to my browser. Or: Title: LivingRoomPC Message: Shutdown Will shut down the computer.

  The problem with ntfy for me is that I get notifications on my mobile through the ntfy app. On desktop, in the browser (Safari on Mac), I only get notification pop-ups when the website is open. The worst part is that I don’t even see the notifications on the website that I received on my mobile while the website wasn’t open.
  - binwiederhier 2mo ago
    Go to ntfy.sh/settings and enable background notifications. Or do it like I do it an pin the tab and just leave it open. Unless you have a pro account, notifications are only cached on the server for 12h so that's why you may miss old notifications.

  Email notifications are dependent on whatever push notifications your email app are using. Either it's set to reach out and check for new messages at a set interval or use a service like bluemail where you hand over your credentials and they send you a proper push via APNS or Google. Either way not as reliable in my experience.
