What exists on Show HN

Built, still asked for61 Show HN launches do this job, and 15 more do part of it. People still ask, so the launches are missed, unknown, or not what they want. Ask what they’re missing before you build.

Instead of: Hacker News, Google News

The idea, as matched

A filter for news feeds and Hacker News that hides what you don't want, such as chosen topics or keywords, AI slop, clickbait, paywalled domains, or items already seen, using rules or a natural-language AI filter.

Jev first matched 75 requests to this idea; a second reader kept 45 of 75.

Every ask, newest first

Each line is an AI paraphrase of what the writer wanted. The link goes to their own words on Hacker News.

Reader’s note. AI-slop filtering dominates since 2023; one duplicate post dropped; search-result blocklists excluded.

Building this?

Read ten of the asks above first, because they say what the existing launches miss. If you ship it, post it as a Show HN so the next run of this list finds it.

Ship it like Vercel, on a server you own

This site runs on ShipTiffin. A push to GitHub deploys it, the way it would on Vercel, but the server is a Hetzner box in your own account. Postgres, sign-in, email, jobs and analytics are already on it, every project gets a hard limit, and nothing is billed by usage.

$19 a month per box, plus about $10 for the server at Hetzner. Open source, so you can also run it yourself for free.
