Twitter alternative. Created by the original founder of Twitter Jack Dorsey.

The Bluesky (open source) implementation of PDS uses SQLite per user.

Check out how it’s built on Data Engineering Whitepapers, helped by Martin Kleppmann.

The code is open-source on

Jack Dorsey introduced the Bluesky project back in 2019 while he was still Twitter CEO. At the time, he said Twitter would be funding a “small independent team of up to five open source architects, engineers, and designers,” charged with building a decentralized standard for social media, with the original goal that Twitter would adopt this standard itself. But that was before Elon Musk bought the platform, so Bluesky is completely divorced from Twitter.

As of May 2024, Dorsey is no longer on Bluesky’s board. Bluesky is now an independent public benefit corporation led by CEO Jay Graber. What is Bluesky? Everything to know about the X competitor.

As an open network, there are tools popping up every day. Here’s my try to collect the most important.

Also, check export or firehoses to extract data from AT Protocol, the underlying protocol on Bluesky. I listed them on AT Protocol.

I heard Bluesky is based on SQLite; here is some background about this. Check more on Personal Data Server (PDS).

Bluesky search features:

Specific phrase: Use quotes ("hello world") - includes alt text matchesHashtags: Use # prefix (e.g., #hello)User mentions:
@username or to:username or mentions:usernamementions:me for posts mentioning you"@username" for literal text matches
Posts from user:
from:usernamefrom:me for your own posts
Combined search: Can mix keywords (e.g., to:username from:me)URL search:
Paste full URL to find matching postsdomain:example.com for all posts linking to a domain

Bluesky does not show on the Analytic, e.g. on GoatCounter it shows off as Unknohttps://www.ssp.sh/brain/Bluesky-20250107215013691.webp0107215013691.webp">

The reason is they didn’t implement a forward proxy. See details here: github.com/bluesky-soci… In my experience, Bluesky leads more traffic as it allows links, unlike Twitter.

It was later revered here (In case you wonder why it was merged).

They implemented an added referral link once (Pass referrer on native (with an opt out) by gaearon · Pull Request #6648 · bluesky-social/social-app · GitHub), but reverted it shortly after. Bsky post
