Push alerts, via ntfy.sh.
ntfy is a free, open-source pub-sub push service: subscribe to a topic in the app, and anything published to that topic pops up on your phone. No account needed. Four steps.
Step 1
Pick a topic and subscribe in the ntfy app
Install the ntfy app (iOS, Android, or the web app at ntfy.sh ) and subscribe to a topic. On the public server, topic names are the only access control — pick something hard to guess:
slashfeed-alerts-x7k2m9
Self-hosting ntfy works too — SlashFeed lets you point at any server URL.
The ntfy mobile app on the 'Subscribe to topic' screen with the topic name typed in, or the topic list showing the subscribed topic.

Step 2
Add the channel in SlashFeed
Open Notification Channels
in the app and click + ntfy. Enter the server URL (
https://ntfy.sh for the public server, or your own instance) and the topic name from Step 1, then save.
SlashFeed's Notification Channels page with the + ntfy form open: server URL and topic fields filled in, and the saved channel row with the ntfy badge.

Step 3
Send a test
Click the paper-plane icon next to the channel — a push notification should appear on your device within a second or two. If nothing arrives, check that the topic in SlashFeed matches the one you subscribed to exactly.

Step 4
Attach a rule
Add a rule that binds the channel to a trigger: every new entry, a specific feed, or a whole category. Matching entries are then pushed to your devices in the background, with automatic retries.
SlashFeed's Add rule form with the ntfy channel selected and a trigger scope chosen, plus the resulting rule row in the Rules list.
