About this app

Hackers' Pub is the social network built for software engineers. Write long-form articles or short posts in Markdown — with syntax highlighting, diagrams, math expressions, and more — and share them across the entire fediverse.
This is an open-source, ActivityPub-enabled platform where developers share knowledge and experience. No ads, no engagement tricks. Just great technical content from people you choose to follow.

WRITE

■ Author articles and posts in Markdown with powerful extensions
■ Syntax highlighting with line highlights, diffs, focus markers, and inline annotations
■ Embed diagrams (Graphviz), math expressions (KaTeX), tables, footnotes, and callouts
■ Save drafts automatically and publish when you're ready

DISCOVER

■ Follow hackers, engineers, and creators across the fediverse
■ Browse curated recommendations or explore the public timeline
■ Search by people, posts, or hashtags

CONNECT

■ Reply, repost, quote, and react to posts from across the fediverse
■ Interact with users on Mastodon, Misskey, Akkoma, and any ActivityPub server
■ Build your profile with a bio, avatar, and verified links

READ WITHOUT BORDERS

■ Multilingual posts with automatic translation — read content in your preferred language
■ AI-generated summaries for long articles so you can decide what to dive into
■ Filter your timeline: articles only, latest first, or recommendations

BUILT FOR DEVELOPERS

Unlike general-purpose social networks, Hackers' Pub treats code as a first-class citizen. Your code blocks aren't just monospaced text — they come with full syntax highlighting, line annotations, diff views, and more. Write a technical article the way it's meant to be read.

FEDERATED, NOT SILOED

Hackers' Pub is built on ActivityPub, the same open protocol that powers Mastodon and the rest of the fediverse. Your followers on Mastodon can read your articles in their home feed. You can follow anyone on any compatible server. No walled gardens, no lock-in.


OPEN SOURCE

Hackers' Pub is free and open-source software, licensed under AGPL-3.0. You can read the code, contribute, or run your own instance. Built with Fedify, the TypeScript framework for ActivityPub.
