Show HN: HNping 'remind me later' for HN via web push
HNping lets you set a reminder for a HN post. You get a web push browser notification when it's time, and clicking it takes you back to the post. That's it.
I built HNping because I kept stumbling on HN posts where the discussion still had to get going. Wanted to revisit, but didn't want to create even more bookmarks/etc I'll just forget about. So I created a 'remind me later' tool (like the reddit bot) to fix this for myself.
To use it: go to hnping.com, enable notifications, and drag the bookmarklet to your bookmarks bar. Then click it on any HN post to set a reminder (5 minutes to 1 week). No personal info needed - you just get a UUID that serves as your account.
I tried to make it as simple as possible.
It's built on a Cloudflare Worker with D1 for data storage and uses Firebase Cloud Messaging for push notifications.
