Bluesky, the still invite-only social app from Twitter founder Jack Dorsey, got a big boost, but so did Spill and Post.News. People rediscovered Mastodon, the distributed, open source social network, although the surge in traffic it attracted didn't quite equal what it enjoyed during the original "Twitter migration" after Elon Musk took over as Twitter's owner. Threads, the Twitter-like app from Meta Platforms that will be a kissing cousin to Facebook and Instagram, could have a bigger impact with its planned launch on 6 July.

We took a 360-degree digital look at the impact of these developments, taking advantage of an improved iOS app data model that will be released to Similarweb users in the coming weeks, rounding out a platform that also includes Android app data and our renowned web traffic and engagement metrics.

Key takeaways

• Bluesky's iOS app had about 240,000 daily users on Saturday, a recent peak, up from less than 100,000 the day before, according to Similarweb estimates for the US. Meanwhile, its waiting list signup website, bsky.app, topped 750,000 daily visits on Saturday and Sunday, up from under 100,000 in the days prior.

• Spill, another pre-launch contender, got more daily unique visitors, nearly 52,000, to its website, spill.com, than any of the other Twitter competitors discussed here – even though it's still just a waitlist website. Spill has been promising to foster a more diverse community than Twitter.

• On Sunday, traffic to mastodon.social, the flagship website of the Mastodon's distributed social network was up 18% compared to an average day over the last month. Mastodon is a little more complex to sign up for than a commercial rival and previously wasn't able to sustain the surge in usage it saw in the fall.

• By total traffic, Spill and Post.News, which particularly appeals to journalists and news junkies, were relatively close behind Mastodon. On Sunday, mastodon.social got about 75,000 daily visits while Spill and Post.News got about 62,500. But that compares to over 42 million visits for Twitter, despite its issues.

Musk, who recently hired a new CEO for the company but continues to oversee its engineering, announced limits on Twitter access as necessary to address "extreme levels of data scraping & system manipulation," which many took as a reference to visits by data-hungry bots like ChatGPT. The limits particularly apply to new accounts and users without a Twitter Blue subscription.

Many commentators speculated that the real cause of the slowdown was an engineering failure possibly related to unpaid cloud hosting bills, not unlike Twitter's early struggles with system capacity that gave rise to its iconic fail whale error message.

Whatever the reason, the change left many active Twitter users frustrated and angry.

Bluesky has people clamouring to get in

An invitation to Bluesky has been a hot ticket for months, but Twitter woes sent potential users stampeding to the waiting list signup website as well as the Bluesky corporate site.

Meanwhile, Bluesky's iOS app had the highest engagement to date, as measured by daily active users.

Downloads from the Apple App Store also reflected strong interest, giving Bluesky its highest App Store ranking to date.

The trend on Android is similar, with Bluesky the winner – although, to be fair, we should note that the numbers for Mastodon shown above refer to the official Mastodon app, which is one of several apps Mastodon users use to check in with the Mastodon network.

Spill wins the web

Turning to the web, we see the winner is Spill with +22K unique visitors on Saturday, 1 July. In other words, some other sites got more visits (including multiple visits by the same individual), but Spill had more unique individuals checking it out.

New interest in Mastodon

Mastodon site administrators reported an influx of new and returning users this weekend, and we can confirm evidence of it in the traffic to mastodon.social – one of many nodes in the distributed social network but also the flagship site started by the software's author. The traffic surge isn't quite as big as the one Mastodon experienced when Elon Musk initially took charge at Twitter, however.

Rivals gain from Twitter's pain

Whether any of these apps is destined to become "the next Twitter," we don't know – they're all still tiny measured against Twitter's scale. This could be their last moment of glory before they are eclipsed by Threads, rumored to be the name of the a forthcoming social messaging platform from Meta Platforms, the owner of Facebook and Instagram, which has a lot going for it.

Or, for Bluesky or Spill, the surge that started this weekend could be the beginning of a meteoric rise that will turn them into true Twitter rivals.
