Bluesky is rethinking what a social media platform can be. Built on a new protocol and supported by developers and third-party apps, the Bluesky algorithm gives users more control than major platforms allow.
As of December 2024, Bluesky had reached 25 million users, a sharp rise from 14.5 million just two months earlier. This growth shows that people are ready for a social network shaped by choice, not one controlled by a single company.
Instead of a top-down system, Bluesky works through a structure that connects your app, your data, and your experience. Users interact through personal data servers, and feeds are shaped by community input. The platform composes third-party services into a smooth experience that feels familiar but works differently behind the scenes.
What you see is not based on one set of rules. It reflects your decisions, your interests, and the people you follow. That power shift is what makes the Bluesky experience stand out. It is social media designed to feel personal again, with room to grow, fewer blocks, and more ways to create, connect, and share.
This blog will entail detailed information on the Bluesky algorithm.
Does Bluesky Have an Algorithm?
Yes, Bluesky does have an algorithm, but the Bluesky algorithm works differently from most social media platforms.
Bluesky flips the script by giving users, developers, and communities more control over how posts appear, how feeds are built, and who gets to decide what trends. Bluesky offers small businesses the opportunity to connect with an audience eager for genuine interactions, free from the constraints of algorithmic filters.
The Truth Behind “No Algorithm” Claims

Bluesky doesn’t operate on the kind of algorithm that filters your feed without your consent. It doesn’t depend on a single company to decide what shows up in people’s timelines. Instead, the Bluesky algorithm runs on an open social media architecture that lets users keep control.
While the app feels like a social network, it behaves differently under the surface. Your account connects to a personal data server, and your feed is shaped by services you choose, not enforced rules from above.
The platform was never meant to push a single approach. From the early days, Bluesky was built to avoid perceived algorithmic manipulation, something that’s common on other platforms. Users can create their own algorithm or subscribe to one they trust, bringing a more user-driven social experience to life.
Chronological Feed vs Algorithmic Feeds

The difference between chronological feeds and algorithmic feeds on Bluesky is that chronological feeds display posts from followed users in time order without ranking, while algorithmic feeds use the Bluesky algorithm to curate content based on user interactions and interests.
The home timeline shows posts from people you follow, in the order they’re shared. But if you want more variety, you can subscribe to feeds made by developers, communities, or third-party apps. These might show trending topics, recommended quote posts, or posts related to your interests.
Unlike major platforms that run a single feed for all users, Bluesky allows users to switch between feed types freely. Whether someone wants pure updates or curated posts, the platform doesn’t lock people into one system.
Understanding Algorithmic Choice

Bluesky’s biggest shift is algorithmic choice. Instead of one company deciding how a feed works, anyone can build or use a custom feed with their own rules. That’s where the feed generator comes in.
Developers can create feeds around any topic, such as cat photos, music, and local news, and share them across the network. This flexibility allows Bluesky users to change the algorithm by selecting feeds or building their own, offering a highly personalized experience.
The Bluesky algorithm doesn’t exist as a single fixed code. It is a network of algorithms built by many, powering an open ecosystem. The Bluesky algorithm separates moderation tools, allowing third-party services or community-developed moderation to handle them outside the main app. This setup gives users more control, stronger anti harassment features, and the ability to shape a Bluesky experience that fits their style.
How Does the Bluesky Algorithm Work

The Bluesky algorithm works through a decentralized system that operates via feed generators, which allow users to create and customize their content feeds, while the Bluesky algorithm maintains transparency by separating moderation tools from content ranking.
The Bluesky algorithm differs from traditional social media algorithms because the Bluesky algorithm uses multiple customizable feed generators instead of a single fixed algorithm, while traditional platforms lock users into one company-controlled ranking system.
The Bluesky algorithm gives users control over their algorithmic feeds because the Bluesky algorithm enables users to subscribe to, create, or switch between multiple feed generators that operate according to their personal preferences and interests. Users can subscribe to or create their feeds based on their interests, whether it’s cat photos, trending topics, or quote posts.
The Discover feed algorithm shows content based on your interactions, and the system is fully visible, not hidden behind complex algorithms. With personal data servers, users can maintain control over their preferences across apps.
Bluesky separates moderation tools from the algorithm, ensuring a more modular, user-driven experience without hidden biases or restrictions.
Bluesky Algorithm vs Traditional Algorithms
Most social media platforms still run on a single, closed system. Bluesky flips that model by building an open, modular network. Users can shape their own feed experience using the Bluesky algorithm, without being locked into one company’s rules or a single algorithm. This model provides a great opportunity for content creators and businesses, giving monetization opportunities with the help of the Bluesky algorithm.
Traditional Platforms | Bluesky Experience |
Single algorithm for all | Users subscribe to or create custom feeds with their logic |
Hidden feed rules | Each feed generator is transparent and user-controlled |
Ranking and moderation are combined | Moderation tools and feed ranking are handled through separate services |
Data tied to one company | Personal data servers let users move across apps with full account access |
Same feed structure for every user | Supports custom algorithms for everything from trending topics to memes |
Closed system controlled by the platform | Built on an open ecosystem where services are composed by developers and users |
Tied to one app | Runs as a social network protocol that supports third-party apps |
Feels locked down and limited | Designed for user control, freedom, and future-friendly social media architecture |
What Makes the Bluesky Algorithm Unique

The Bluesky algorithm isn’t trying to copy what other platforms are doing. It’s creating something that puts the user first, powered by modular design and real control. Here’s what sets the Bluesky algorithm apart:
Modular by design
The Bluesky algorithm isn’t one giant feed that everyone’s stuck with. It’s made up of many feed generators that developers, apps, or communities can build. These generators decide how content gets sorted, and anyone can use or create them.
Feeds you actually choose
Whether it’s popular photos, trending topics, or quote posts, users can subscribe to feeds that match their mood. Pin your favorites, switch them out anytime, and shape your home timeline without being forced into a default view.
Your data, your rules
Each user account connects to a personal data server. That means your posts, likes, and follows don’t rely on one company’s control. You can switch apps or third-party services and still keep your data intact.
Moderation handled separately
Moderation tools don’t get mixed in with the Bluesky algorithm. Instead, Bluesky uses moderation services developed by others, often by the community, keeping ranking decisions and safety controls apart.
Built for future updates
The Bluesky algorithm runs on a protocol that supports new features without breaking the core experience. It’s a social network that stays flexible, without locking users or developers into a single direction.
This model supports a user-driven social experience that feels more open, more transparent, and far more adaptable than anything built by a single company.
Bluesky’s Vision for Algorithmic Transparency
Bluesky is building a social media platform where the algorithm is open, not hidden behind a wall of code. Algorithmic transparency in Bluesky means that the Bluesky algorithm operates through visible feed generators and open architecture, where users can see how content ranking works, while the Bluesky algorithm separates moderation from ranking to prevent hidden manipulation.
Open feed architecture
Instead of locking everyone into one timeline, Bluesky uses feed generators. These are open tools developers can use to create algorithmic feeds. Each one sorts posts based on custom logic. Anyone can subscribe to them, switch them out, or pin their favorites.
No forced defaults
Feeds like Discover or the home timeline aren’t controlled by one company. Users choose what they see. The Bluesky algorithm doesn’t quietly shape content behind the scenes. It’s made to be visible, adaptable, and user-selected.
Modular moderation
Moderation services are not part of the feed system. They run on their own, often created by third-party services or the community. This separation prevents silent ranking bias and gives moderation tools like blocking or filters their own space in the network.
Built on protocol
Every feed, app, and moderation tool connects through Bluesky’s protocol. It composes third-party services into a seamless user experience while giving people control over their data, account, and the way their social app behaves.
No perceived manipulation
Since the Bluesky algorithm is public and user-driven, there’s no hidden ranking system shaping people’s timelines. The Bluesky experience is built for control, not confusion, with room for future updates and feed innovation as the network grows.
How Bluesky Ranks and Recommends Content

The Bluesky algorithm ranks and recommends content through multiple visible feed generators that each apply different ranking logic, while the Bluesky algorithm uses modular components like the Discover feed and custom algorithmic feeds to surface relevant posts based on user interactions. It breaks content ranking into visible, modular pieces, each working together to give users more control over what shows up on their screen.
The Bluesky recommendation algorithm plays a key role in this, analyzing user activity such as likes, reposts, and follows to surface content that matches their interests. Keep your feed active and organized with the Bluesky Scheduler and ensure posts are timely and relevant.
When you schedule posts through RecurPost’s Bluesky Scheduler, the Bluesky algorithm treats scheduled content the same way as real-time posts once they go live. The algorithm evaluates scheduled posts based on timing, user interactions, and feed generator logic, making strategic scheduling a valuable tool for content visibility across different feed types.
Discover Feed
The Bluesky Discover algorithm functions by analyzing user interactions such as likes, reposts, and follows to surface relevant content and trending topics, while the Bluesky Discover algorithm operates through a transparent feed generator that avoids manipulative ranking practices.
It works through a feed generator that learns from your actions: likes, reposts, follows, and surfaces content from other users in a way that feels relevant without falling into perceived algorithmic manipulation.
Custom Algorithmic Feeds
Unlike major platforms, where one algorithm runs the entire network, Bluesky supports many. Developers and communities can build custom feeds powered by their logic. Whether it’s a feed for quote posts, niche discussions, or just cat photos, users can subscribe and pin them as needed.
Chronological Home Timeline
For users who want posts in real-time, Bluesky still keeps the chronological feed front and center. No ranking, no reshuffling, just posts from the people you follow, in the order they were shared.
Feed Generators in Action
Each feed runs independently and can be shared across the network. Bluesky composes third-party services like these into a seamless user experience that connects apps, feeds, and accounts without disruption.
Moderation Runs Separately
Moderation tools are not tied to feed ranking. These are handled through moderation services that operate outside the algorithm, often built by third-party apps or the community itself.
This entire flow is powered by personal data servers and an open protocol. Bluesky doesn’t just offer another social app. It gives users a social media architecture they can move through, remix, and control.
How Post Scheduling Works with the Bluesky Algorithm
Post scheduling on Bluesky works seamlessly with the platform’s algorithmic feeds and feed generators. When you use tools like RecurPost’s Bluesky Scheduler, your scheduled content integrates naturally with the Bluesky algorithm’s content distribution system.
Scheduled Posts and Feed Generators
Once scheduled posts go live, they enter the same feed generator system as real-time posts. The Discover feed algorithm evaluates scheduled content based on user interactions, timing, and relevance, treating it no differently from manually posted content.
Timing and Algorithm Performance
The Bluesky algorithm considers post timing when ranking content in algorithmic feeds. Scheduled posts that align with when your audience is most active can perform better in custom feeds and the Discover feed, as the algorithm factors in immediate engagement patterns.
Cross-Feed Distribution
Scheduled content appears across all feed types: chronological home timelines, custom algorithmic feeds, and the Discover feed. This means your scheduled posts reach users regardless of which feed generator they’re using, maintaining consistent visibility across Bluesky’s modular feed architecture.
Personal Data Server Integration
Scheduled posts are stored and distributed through your personal data server, just like regular posts. This means scheduled content maintains the same level of user control and data ownership that makes the Bluesky algorithm unique.
Discover Feed vs Custom Feeds
Bluesky’s social media architecture gives users two very different ways to experience their feed, each built to serve a different kind of browsing.
Feature | Discover Feed | Custom Feeds |
What it shows | Posts related to your interests, trending topics, and activity from other users | Feeds built around anything, from cat photos to quote posts |
How it’s built | Runs on an algorithmic feed shaped by your likes, reposts, and follows | Created using custom algorithms by developers or community members |
User control | View only algorithm logic is visible, but not editable | Users can subscribe, pin, or even create their feed |
Who creates it | Built by Bluesky using a transparent feed generator | Built by developers, third-party apps, or users with coding ability |
Moderation link | Moderation runs separately, using external tools | Works independently from the moderation services developed by others |
Where it appears | Accessible through the Discover tab inside the app | Can be pinned directly to your home timeline alongside the chronological feed |
Social media structure | Part of the Bluesky algorithmic offering in a user-driven social experience | Reflects the open ecosystem and composable social media architecture |
Flexibility | Built for broad discovery, not custom niches | Fully flexible feeds can be made for any topic or interest |
How to Change the Algorithm on Bluesky
Bluesky was built to give users more control, and switching or customizing feeds is a big part of that. The process is fast, flexible, and fits naturally into the app’s modular design.
1. Start on the Home Timeline

This is your main view, showing posts from people you follow in chronological order. No reshuffling, no hidden filters, just a clean, real-time feed.
2. Tap the Feed Selector

At the top of your screen, you’ll see tabs for each active feed: your Home timeline, the Discover feed, and any custom feeds you’ve added. These are powered by feed generators that run through your personal data server.
3. Browse or Search for New Feeds

Bluesky offers a built-in feed directory where you can find custom feeds built by developers, creators, or third-party apps. Whether you’re after quote posts, trending topics, or a stream of cat photos, there’s a feed for it, each running on its custom algorithm.
4. Pin, Reorder, or Remove

Users can customize or change the Bluesky algorithm by subscribing to different feed generators, pinning preferred feeds to their main view, and switching between chronological and algorithmic feeds, while the Bluesky algorithm allows users to reorder or remove feeds entirely based on their preferences. Long-press any tab to rearrange its order or remove it entirely. This creates a seamless user experience that works the way social apps should have all along.
Content Moderation of the Bluesky Algorithm

Content moderation works with the Bluesky algorithm through a separate system where the Bluesky algorithm handles content ranking while independent moderation services manage filtering and safety controls, ensuring that moderation operates independently from the algorithmic feed logic. This separation changes how posts are filtered, ranked, and controlled across the network.
Content Ranking ≠ Content Moderation
The Bluesky algorithm handles what shows up in feeds, but it doesn’t control what gets blocked. That job belongs to moderation services, which run separately from feed generators. This design removes the chance of a single company blending ranking with censorship.
Third-Party Moderation
Moderation is managed through third-party services or tools developed by the community. Users can choose moderation layers based on their comfort level, from broad filters to topic-based controls. These services can block accounts, filter posts related to sensitive topics, or apply anti harassment features.
Feed Freedom, Filtered Safely
Users can still subscribe to custom feeds and switch between them freely. Whether it’s a feed full of cat photos, trending topics, or quote posts, each one is filtered by the moderation setup that the user chooses. That means no blanket rules, just modular tools built to protect and adapt.
Built Into the Architecture
Everything connects through Bluesky’s open protocol. Feed generators, moderation tools, and personal data servers all work together without forcing one approach. The result is a feature-complete experience that supports safety without compromising on user control.
Developer Tools & Feed Generator Kit
Bluesky isn’t just a social media platform for users; it’s also a playground for developers. From the early days, the network was designed to support open contributions, modular feeds, and flexible moderation setups.
Here’s how it works under the hood:
What is a Feed Generator?
Feed generators in the Bluesky algorithm are modular tools that read public posts and apply custom logic to create personalized timelines, while these feed generators allow developers and communities to build feeds around topics like trending content or niche interests. It reads public posts, filters or scores them using custom logic, and returns them as a ranked timeline. This process is what drives feeds like Discover, trending topics, or niche collections like cat photos and quote posts.
Build Your Algorithm
Developers create custom feeds for the Bluesky algorithm by using open tooling and starter templates that allow them to build feed generators with custom logic, while the Bluesky algorithm supports these custom feeds through GitHub resources and a modular network architecture. Feeds can be as simple or complex as needed. Developers can pull data from personal data servers, apply custom filters, and publish feeds that others can subscribe to inside the app.
Starter Kits and Resources
Bluesky provides starter templates and examples on GitHub. These kits help developers create feeds from scratch, test them, and deploy them as part of the open social media architecture. No central approval is needed. Feeds can be built, shared, and refined by the community or through third-party apps.
Part of a Modular Network
Every feed runs independently. This means developers can create niche feed services without affecting others. Bluesky’s system composes third-party services into one seamless user experience, with ranking, moderation tools, and apps all functioning as separate, connected parts.
This flexibility has brought in a growing base of developers, hobbyists, and early adopters, all helping Bluesky grow beyond what’s possible in a single company system like Twitter. With over a million users already shaping their feeds and moderation layers, the network keeps expanding through its open, user-driven design.
