One button to reach them all.
A share button that lets people pick their network — and remembers their choice across every site.

<atshare-selector></atshare-selector>Why atShare
Built for the open web.
01
Every network, one button.
Bluesky, Blacksky, Mastodon, LinkedIn, and more — your audience picks their destination from a single, clean selector.
02
Preferences that follow.
When someone authenticates, their preferred network is stored on their own PDS — not your site. The next site running atShare already knows where they want to share. Protocol-native and portable.
03
One script tag. Done.
A single web component with zero dependencies. Themeable to match your site. Works everywhere HTML works.
04
Open source. Community-built.
atShare composes existing open infrastructure — Microcosm for identity resolution, AT Protocol for preference storage. No tracking, no vendor lock-in, no accounts on our end.
How it works
Set up in seconds. Works for everyone.
Embed
Drop one script tag and a custom element onto your page. No build step. No configuration.
User clicks
A clean selector opens showing every supported network — ATProto clients, Fediverse, and beyond.
Picks a network
They authenticate once with their ATProto handle. Their choice is saved to their own PDS — not your server.
Remembered everywhere
Every site running atShare reads that preference. Their network follows them — no new accounts, no tracking.
Designed and built by R. Michael Thomas — an independent developer building open, portable infrastructure for the AT Protocol ecosystem. atShare is part of a small but growing collection of tools aimed at making the open social web as frictionless as the closed one.
The social.atshare.preference lexicon record is the core innovation here — a single AT Protocol record type that stores where a person likes to share, living on their own PDS and readable by any site embedding atShare. No central registry. No account on our end. Portable by design.
atShare is open source and built to compose. Publishers, developers, and open-web communities are all welcome. If you ship content — articles, portfolios, projects, anything — atShare gives your readers a share button that respects where they actually live online.
