Different model: Spark uses AT Protocol to offer portable social identities and greater user control over feeds.
Huge scale gap: TikTok dominates through its massive audience, creator ecosystem, recommendation engine and mature monetization.
Interesting experiment: Spark’s significance lies less in beating TikTok and more in testing a more open social-video model.
Reelo, the short-video app once linked with Bluesky, now operates under the name Spark or Spark Social. The change took place in 2025 as the project moved from an early TikTok-style experiment toward a broader social platform. Spark remains in open beta in August 2026, so the service still sits far from the scale of major short-video networks.
The app has a clear goal. Spark wants to offer the fast, vertical video experience that made TikTok famous, but with a different approach to ownership, algorithms and social identity. Instead of placing the entire service under one company, Spark uses AT Protocol, the open protocol also used by Bluesky.
TikTok gives users a highly personalized For You feed. ByteDance controls the main recommendation system, the platform rules, account structure and much of the wider content ecosystem. Spark takes another route. Its users can choose different feeds and decide how content reaches their screen.
Spark supports personalized recommendations, chronological feeds and custom feeds from other sources. That choice sits at the centre of the product. A user does not have to rely on one recommendation system for every video.
This makes Spark more than another TikTok copy. The app tries to change the basic relationship between a social network and its audience. TikTok asks people to trust its algorithm. Spark gives more control over the systems that select content.
AT Protocol gives Spark its biggest technical difference. The protocol supports portable social identities and data across compatible services. Spark can therefore connect with a wider network instead of operating as a completely closed platform.
The original Reelo project started with a simple challenge. Bluesky had social-network features, but its early video system did not offer everything required for a full short-video service. Spark's team chose to create its own backend and codebase while keeping AT Protocol at the foundation.
That approach also gave the product more freedom with video. The original Spark system supported videos up to three minutes. At that stage, Bluesky had a one-minute video limit. Spark also planned tools such as filters, effects, music, advanced editing and live video.

The basic experience feels close to other short-video apps. Spark supports photos, videos, Stories, direct messages, search and a built-in editor. Stories disappear after 24 hours. The platform also supports reusable sounds and several tools for video creation.
Recent software updates show that the project still has active development. The Android version reached 0.12.2 in June 2026, with improvements for video playback, sounds on photo posts, the editor, Explore, notifications and direct messages. Public code activity also continued into August 2026.
The source code remains open under the MIT license. Developers can inspect the project and build from the available code. That open approach separates Spark from TikTok, which keeps its core platform technology under company control.
The difference in scale between the two platforms remains enormous. TikTok had an advertising audience of at least 1.59 billion people worldwide in January 2025. Industry estimates for 2026 continue to place TikTok near the 1.5 billion to 1.6 billion user range.
Spark has nothing close to that reach. Its Google Play listing currently shows more than 1,000 downloads. That number does not represent total Spark users, since the figure excludes the full iOS audience and other possible access routes. Still, it shows the enormous distance between the young platform and TikTok.
Spark therefore does not compete with TikTok on audience size. Its main competition lies in its approach to social media.
TikTok has spent years refining short-video recommendations. Its vast audience creates a huge supply of videos, while its large creator base attracts brands, advertisers and new viewers. Music licensing also gives TikTok a major advantage. Popular sounds can turn a simple clip into a trend that reaches millions of people.
Spark has to develop that entire ecosystem from a much smaller base. A good interface alone cannot solve that problem. Short-video platforms need a steady flow of fresh content, creators and viewers. Without enough activity, a feed can quickly feel empty.
TikTok also has a mature creator economy. Spark remains far earlier in that journey. In 2025, the Reelo team discussed advertising and subscriptions as possible revenue sources, along with revenue sharing for creators. No public evidence shows a creator-payment system anywhere near TikTok's scale today.
India presents a special market for any TikTok alternative. TikTok remains officially blocked in India. In August 2025, TikTok denied reports of a return to the country, while Indian officials confirmed that the ban had not ended.
That situation leaves room for other short-video services. Still, Spark should not be described as an Indian TikTok replacement. The platform remains small, and India's short-video market already has strong local and global alternatives.
The more useful point concerns timing. TikTok's absence gives alternative platforms a large potential audience, while Spark offers a different technical model from the usual closed social network.

Spark has little chance of defeating TikTok through scale alone. The numbers make that clear. TikTok has more than a billion users, a massive creator base and a mature commercial system. Spark remains in open beta with a small public footprint.
The real experiment sits elsewhere. Spark asks whether short video can work with portable identities, open software and user-selected recommendation systems. The product still needs far more creators, content and commercial support before it can challenge established networks.
Reelo may have started as a TikTok-style app for the Bluesky world, but Spark now carries a larger ambition. The project does not simply copy TikTok's vertical video format. It tries to change who controls the feed, the identity and the wider social network. That makes Spark a small competitor today, but a notable experiment in the future of social media.
1. What is Spark Social?
Spark Social is the successor to Reelo, a short-video platform built around AT Protocol and designed as a more open alternative to conventional social networks.
2. How is Spark different from TikTok?
Spark lets users access different recommendation and chronological feeds, while TikTok primarily relies on its centrally managed For You recommendation system.
3. Does Spark use AT Protocol?
Yes. AT Protocol provides the foundation for portable identities and interoperability with compatible social services, connecting Spark to the broader Bluesky ecosystem.
4. Is Spark bigger than TikTok?
No. TikTok operates at massive global scale, while Spark remains in open beta with a comparatively small user base and public footprint.
5. Can Spark replace TikTok?
Spark is unlikely to challenge TikTok on scale in the near term. Its bigger opportunity is demonstrating whether short-form video can thrive under a more open, user-controlled model.
