Why DevFeed exists
Hacker News has great content, but it is not always comfortable to consume on a phone. DevFeed turns that content into a calmer, more readable experience — and keeps the important parts visible: the story, the discussion, the context, and the ability to come back later.
The goal is not to replace Hacker News. It is to make the experience feel lighter, clearer, and more intentional on mobile.
Readable by default
Type sizes, spacing, and hierarchy tuned for a phone.
Nothing extra
No feeds you did not ask for, no interruptions.
Context stays close
Article and discussion are one tap apart.
Independent
An unofficial client built on the public Hacker News API.

The cost model is the interesting part here. Rule-based planners fall apart the moment joins get wide.
Agreed. Curious how it behaves with skewed data — TPC-H is generous.
900 lines is a great teaching artifact. Reading it end to end took an evening.

Summaries and discussions
AI summaries help break down an article quickly when you want the gist before the full read. They sit inside the article view as a few plain points — nothing more.
Discussion views keep the conversation close at hand, so the context around a story stays intact while you read.
A summary is a shortcut, not a replacement. The article and the thread are always one tap away.
Personal reading flow
DevFeed helps you keep reading lightweight and intentional. Save the stories worth coming back to, and pick up where you left off.
