There are a handful of forks of the Bluesky social-app, which is written in React Native for web, iOS, and Android.
These may or may not re-use the Bluesky AppView for content, or be configurable to use different ones.
These are “Bluesky clients” in the sense that they are typically deployed as web front ends.
Blacksky
Fork of Bluesky customized for community use. Decentralized social media built for community power, culture, and collective freedom.
Features — Today
Blacksky ships everything you expect from the upstream Bluesky client plus community-specific defaults:
- @blacksky.app moderation service is the default and cannot be disabled, providing strong anti-harassment filtering out-of-the-box
- Blacksky: Trending feed replaces Discover as the landing feed
- New @blacksky.app users sign up on the Blacksky PDS and receive
*.blacksky.apphandles
Witchsky
The Witchsky client is a fork of (Kitty, deer.social, then) social-app that adds:
- Color themes (defaults to orange), including of other forks & clients
- Buttons to open original bridged posts (from the fediverse) and in PDSls
- The ability to redraft skeets (posts are called skeets btw)
- Clear indicators of if you’re mutually following someone
- Options to disable all visual numerical metrics (like follower, like, etc. counts)
- Square avatars for everyone (not just labelers) and buttons
- Better defaults, like forcing alt text for images and hiding similar account recs.
- Clickable handles for real domains (besides .bsky.social subdomains)
- Automatic PDS resolution based on handle at sign-in
- Trusting your own preferred verifiers (and to operate as one)
- Re-attaching disconnected quotes
- A toggle to disable redirects through go.bsky.app
- Other features mentioned in the README
Not based on social-app
Red Dwarf
A Bluesky client that does not use any AppView servers, instead gathering data from Constellation and users’ PDSs.
Impro
A Bluesky client aiming for feature parity with social-app with less restrictive blocking, further nested quotes, and theming options to change the highlight color of the UI.
Outdated Bluesky social-app forks
Catsky
Branded fork of social-app with a Catppuccin mocha theme and automatic PDS resolution based on the handle entered at sign-in.
Bluenotes
A rebranded fork of the Bluesky social-app with a Community Notes feature.
Deer Social
A social-app fork with added features, which many other forks were based on. The GitHub README goes into detail on features and approach:
As a rule of thumb, the best features for deer.social are ones that have a disproportionately positive impact on the user experience compared to the maintenance overhead. Unlike some open source projects, since deer.social is a soft fork, any features (patches) we add on top of upstream social-app need to be maintained.
Without an overriding motivation, opinionated features should exist behind a toggle that is not enabled by default. This allows deer.social to cater to as many users as possible.
Deer Social (ayla)
A deer.social fork (based on another now-defunct fork called Kitty, which is also what Witchsky was based on) with everything its predecessors had, but a bit more updated, and with:
- Image thumbnail/full-size format selectors
- Pronouns, join month/year, and website on profiles
Gsheps
A branded fork of social-app that uses npm in place of yarn.
Gems
Fork of social-app customized for cryptocurrency wallet attachment.
