Decentralized social media searches rise as Bluesky hits 35 million users

Decentralized social media operates on independently run servers. It reduces the power and control that traditional platform owners have over both users and content.

Exploding Topics data shows search interest in decentralized social media has more than doubled in the last 5 years amid rising dissatisfaction with platforms like Facebook, Instagram, and X.

“Decentralized social media” searches have risen 138% in the last 5 years, peaking at over 4,000 searches per week recently. 

The average user now spends time on 6.8 social platforms per month, a 2.3% YoY increase. This suggests users are comfortable engaging with multiple platforms simultaneously.

So new, decentralized platforms don’t need to dethrone these established giants to build up their own user bases. They simply need to build critical mass.

With users leaving X in their droves, and a potential US ban still hanging over TikTok, conditions have rarely been better for a massive shift in how we conceptualize and use social media.

Read on to find out about platforms like Bluesky, Mastodon, and Pixelfed, and the changes in the social media landscape that are allowing them to flourish.

What is decentralized social media?

Decentralized social media is an alternative ownership model for social media platforms. It shifts control away from individuals or tech giants and back towards users.

Rather than the network being hosted on a central collection of servers, decentralized platforms are hosted across a network. The servers in the network are managed by its participants.

Some social media platforms use the shared ActivityPub protocol. This allows users to share content from one network to another. This ecosystem is known as the Fediverse.

“Fediverse” occasionally gets some big search spikes when decentralized social media hits the news. Overall, searches are up 433% in the last 5 years.

The promise of decentralized social media is a series of platforms that are ultimately controlled by the users.

Meta’s unwanted pivot to virtual reality was Zuckerberg’s brainchild. Musk has made X his personal political plaything. The threat to TikTok comes from the US government.

Decentralized social networks are less susceptible to the whims of individuals and governments.

Let’s take a look at some of the emerging decentralized social media platforms.

Bluesky

Bluesky has achieved the most mainstream appeal of any decentralized social media network. It currently has approximately 35 million users.

“Bluesky” searches are up 775% in the last 2 years.

It launched on an invite-only basis in February 2023, and went fully public a year later. Users have created more than 1.5 billion posts on the platform.

Bluesky has been a major beneficiary of the exodus from X because it offers a user experience highly similar to pre-Musk Twitter. That shouldn’t be a surprise, given that it was developed by Twitter founder Jack Dorsey.

The Bluesky interface. Look familiar?

In fact, Bluesky was developed in parallel with Twitter, with the intention of one day moving Twitter onto a decentralized protocol. But following the takeover, Bluesky became entirely separate.

Dorsey has since left. But the Twitter legacy remains clear in the interface. And on Bluesky, users have far more power to customize their own feeds, rather than handing complete control to an algorithm. That makes the Bluesky experience more like Twitter when it first launched.

Algorithmic feeds can still be beneficial when it comes to content discovery. Just look at TikTok, which is built almost entirely around the “For You Page”.

And Bluesky allows users to choose from over 40,000 algorithmic feeds.

Users can also build their own custom feeds, although it’s not altogether simple for non-developers. Startup Graze recently raised a $1 million pre-seed round for software that makes the process easier.

Bluesky is not part of the “Fediverse”, the collection of interoperable decentralized networks built on ActivityPub. Instead, it uses its own AT Protocol.

However, that protocol is open-sourced. And in December, a $1 million fund was announced for developers building on the AT Protocol, which could in time lead to the growth of a larger atproto ecosystem.

Bluesky CEO Jay Graber recently attended the ATmosphere Conference, held specifically for people developing on the AT Protocol.

“We met a lot of folks there building apps we didn’t know about,” Graber said. “There are private messengers, new moderation tools. 

“The benefit to developers of an open ecosystem is that you don’t have to start from zero each time. You have 34.6 million users to tap into.”

Meanwhile, Bridgy Fed can act as a bridge between Bluesky and any decentralized networks using ActivityPub. But it’s an opt-in service.

Mastodon

Like Bluesky, Mastodon is popular with “Twitter refugees”. It has an estimated 8.1 million users, although only around 850,000 are monthly users.

“Mastodon” searches are up 109% in the last year.

The network is formed of over 9,500 different instances, each with their own rules and interfaces. Around 300,000 users are on the Mastodon.social instance.

Mastodon.social is something of a showcase for the capabilities of the Fediverse. Its main feed looks like X or Bluesky, but it can display posts from different Mastodon instances, and even from non-Mastodon social media networks built on the ActivityPub protocol.

Users on one Mastodon instance can view posts from across other instances.

Truth Social, the go-to platform for President Trump, is built on Mastodon’s open-source code (although it did not initially disclose that, violating the license terms). It has around 6 million active users.

However, Truth Social is not an instance of Mastodon. It uses the same basic code, but it has been “forked” out of the Fediverse ecosystem.

Pixelfed

If Bluesky and Mastodon are decentralized alternatives to X, then Pixelfed is the decentralized version of Instagram.

Like Mastodon, it is built around the premise of separate servers with different rules and limits. It has 1,700 servers, with Pixelfed.social the primary one.

“Pixelfed” interest spiked in January.

Across all servers, Pixelfed has 769,000 users. More than 98 million photos and videos have been shared.

It is built on ActivityPub, meaning posts on Pixelfed can be viewed on Mastodon and vice versa.

Pixelfed looks a lot like Instagram.

The network’s increased visibility in January was ironically partly down to Meta’s apparent attempts to censor it; links to Pixelfed were blocked as spam when shared on Meta platforms.

Skylight Social

Skylight Social is a decentralized alternative to TikTok. Its creators invite you to “join the unbannable short-form video platform.”

(That's clearly a reference to TikTok, although there are numerous banned social media apps.)

“Skylight Social” is the latest decentralized social media platform to see a search spike.

Like Bluesky, Skylight Social runs on the AT Protocol. So users’ content and connections exist on the protocol rather than the platform.

Anyone joining Skylight will automatically be following all of their Bluesky connections and will see their contacts’ Bluesky videos in a TikTok-style feed.

Mark Cuban has backed Skylight with a pre-seed round. He had revealed in January that he wanted to see a TikTok alternative built on the AT Protocol.

Skylight Social has over 50,000 downloads on the Play Store, and over 1,000 user ratings on the App Store, averaging 4.8 stars. At the time of publishing, it is only available in the US.

Flashes

Flashes is another decentralized network built on the emerging AT Protocol.

“Flashes app” searches hit 16,800 per week shortly after the new platform was announced.

It’s essentially the AT version of Pixelfed. In other words, it’s a decentralized Instagram alternative, but one that seamlessly connects with Bluesky rather than Mastodon and other ActivityPub instances.

At the moment, Flashes is only on the App Store. But a GoFundMe for an Android app has raised more than $11,200.

The developer of Flashes based it on one of his previous decentralized apps, Skeets. That was effectively an interface for Bluesky, but one which catered for iPad users and offered customized accessibility features.

Skeets was downloaded more than 30,000 times. That user base did not automatically port across, but Flashes has been able to market to those same users — while ultimately trying to tap into the 35 million people now in the AT ecosystem.

The Flashes app has already been downloaded over 100,000 times in its own right.

Is Threads decentralized?

Threads is not decentralized. However, it has begun to integrate into the Fediverse.

Threads users in over 100 countries can now opt in to Fediverse sharing, which allows for cross-sharing with Mastodon and other ActivityPub servers.

However, Threads is owned by Meta, and questions remain about how well Threads will integrate.

Threads has been even more successful than Bluesky and Mastodon in capturing departing X users. Launched via Instagram, the Meta product has amassed more than 200 million users.

“Threads” searches are up 58% in the last year.

It is primarily text-based, with a 500-character limit. Users can also add photos and videos.

Threads is Meta’s answer to X.

How we got here: social media disruption

We are in an era of major change in social media usage, with politics interacting with tech at a much deeper level than ever before.

Meta’s fight to stay on top

For a long time, the same handful of sites had a stranglehold on the social media space. Half of them were owned by Meta.

Facebook, WhatsApp and Instagram still make up 3 of the top 4 when it comes to monthly active users (MAUs), with the other spot held by Google’s YouTube.

As recently as May 2025, Facebook received 10.5 billion monthly visits. 

In 2024, Meta reported revenue of $164.5B. That was a 22% increase on the previous year.

So Facebook and Instagram are still behemoths, but that means they struggle to pivot as quickly as newer, fresher upstarts.

“Facebook” searches are down 65% in the last 5 years.

After all, the name “Meta” only came about as a result of Mark Zuckerberg’s big bet on the metaverse, an attempt to keep Facebook at the forefront of the social industry for years to come. That’s starting to look like a questionable decision.

Metaverse shopping, metaverse concerts and metaverse sports all made sense when they were first conceived during the pandemic, at a time when real-world counterparts were limited. But all have seen steep, near-identical downturns in search interest.

The idea of “metaverse shopping” has all but died out.

There has been a surge in the idea of social commerce. But it is TikTok which has managed to take a commanding lead on that front, with monthly US shopping revenues of over $1 billion.

Indeed, Instagram is locked in a battle for audiences with TikTok across the board. The Meta platform introduced Reels in a relatively successful attempt to keep pace with the competition, but it has lagged in a number of key metrics.

The average TikTok user in the US spends 43 hours and 53 minutes on the platform each month, whereas the average Instagram user spends just 11 hours and 2 minutes. It’s a similar story when it comes to engagement rates.

Meanwhile, TikTok is now dealing with the threat of alternative apps like RedNote if it's banned. So even one of the newest players in the centralized social media elite is facing a period of significant uncertainty.

The downfall of X (formerly Twitter)

It isn’t just the Meta properties that have paved the way for a restructuring of the social media landscape. In fact, arguably the most significant change recently has been the steep decline of X, formerly Twitter.

As of September 2024, X had lost approximately 20% of its US daily user base since Elon Musk acquired the platform in October 2022. In the UK, that exodus amounted to a third of all users.

X’s overall reported ad reach, a reasonable proxy for the total number of users, fell by 33 million over the last year alone. Those who remain on the platform are almost two-thirds male.

X has struggled since rebranding from Twitter.

Among the remaining US users, the average time spent on the platform per month is just 3 hours and 56 minutes.

And the experience for those who remain is now deeply politicized. Musk is now a member of President Trump’s cabinet, and his own posts are afforded significant visibility on the platform, even beyond his 219 million followers.

Meanwhile, a November 2024 study found that political abuse on X is global, widespread, and cross-partisan.

Moderating decentralized social media

Questions remain about whether decentralized social media networks are capable of moderating content effectively.

The federated nature of these networks is great from a free speech perspective.

But on the other side of the coin, centralized social media has more established mechanisms for flagging and removing content that has no place on the internet.

“Moderation system” searches are up 107% in the last 5 years.

Make no mistake: that is a moral duty. Complete freedom of speech on the internet might sound like a noble goal, but the reality is different.

In a 2023 study by the Stanford Internet Observatory, analysis of 325,000 posts in the Fediverse over 2 days found that over 1,200 contained text relating to child grooming or explicit underage content.

Often, moderation is also a legal duty. So decentralized social media platforms need to find ways of effectively moderating user content.

Bluesky’s moderation system somewhat resembles that of a centralized social media network. There are community guidelines, and moderators are in place to review any content that is flagged or reported.

Amid the growing user base, Bluesky planned last November to quadruple the size of its moderation team to 100. It received 6.48 million user reports in 2024.

It has also developed an open-source “stackable” moderation system. This allows individuals and groups to apply filters which go beyond the default.

Mastodon relies on its system of individual servers, leaving moderation decisions to administrators and moderators on a local basis. But given that the largest server has hundreds of thousands of users, the idea of local moderation being best has faced challenges of scale.
