Reelo (Spark): The Leading TikTok for Bluesky?

A New Video App, Originally Reelo (Now Spark), Differentiates Itself from Bluesky Alternatives

Several projects are currently in development aiming to create a video-focused application for the decentralized social network Bluesky. However, one particular endeavor is setting itself apart: the forthcoming app, initially known as Reelo and now rebranded as Spark.

Building on the AT Protocol

Unlike many competing applications, Spark isn’t constructed as an extension of the Bluesky social network itself. Instead, it’s built directly upon the AT Protocol, the foundational technology that underpins Bluesky. This architectural choice enables a wider range of features.

These features will encompass support for extended video lengths, a variety of video filters and effects, an integrated music library, and, in the future, the capability for livestreaming.

Limitations of Existing Bluesky Video Apps

Constrained by Platform Design

Many existing video applications for Bluesky – including Bluescreen, Videos for Bluesky, and Skylight – are restricted by the inherent limitations of the Bluesky platform.

Because Bluesky was initially conceived as a competitor to X (formerly Twitter), its feature set doesn’t fully align with the capabilities of a platform like TikTok.

Opportunity for Innovation

These constraints create an opening for a new generation of video applications powered by the AT Protocol. These apps, like Spark, can both interact with Bluesky and function independently.

The Development Philosophy Behind Spark

A Dissatisfying Prototype

João Davi S. N., the developer of Spark, based in Rio Grande do Sul, Brazil, initially explored building a video app directly on top of Bluesky. However, he quickly determined that this approach didn’t meet his vision.

“When I finished the first prototype using Bluesky technology, I said, ‘OK, this is crap. I can do nothing with this,’” he explained. He realized that simply uploading videos wasn’t sufficient for creating a compelling experience.

Beyond Basic Video Uploads

João Davi emphasized that the success of TikTok wasn’t solely based on video uploads. “It was music, effects, [and] a variety of capabilities,” he stated. “Creating the video, posting the video is definitely not the most important thing. It’s making videos that catch attention.”

A Unique Architecture

To overcome these limitations, João Davi opted to develop Spark as a video app based on the AT Protocol, but with its own independent backend, codebase, and lexicon – referring to how the app’s visual elements are rendered.

Key Features and Functionality of Spark

Extended Video Length and Livestreaming

This design allows Spark to support videos up to three minutes in length, exceeding Bluesky’s current one-minute limit. Livestreaming capabilities are also planned for future implementation.

Independent Data Storage

Spark will utilize its own PDS (personal data server) for storing user data, while also allowing technically inclined users to host their own PDS, mirroring the functionality available on Bluesky.

Interoperability with Bluesky

The app will enable users to connect with their existing Bluesky contacts. Posting videos from Spark to Bluesky will be an optional feature, potentially implemented as a checkbox within the app’s interface.

When cross-posting, shorter videos can be published directly to Bluesky, while longer videos will be shared as embedded links.

Customizable Feeds

Similar to Bluesky, Spark will offer multiple customizable feeds, including dedicated streams for Bluesky videos, Spark videos, and various topical categories like Music and Dance.

Monetization and Future Plans

Exploring Revenue Models

João Davi is considering a combination of advertising and subscription models to monetize the app, with potential revenue sharing arrangements for creators.

Premium subscription tiers may include features like livestreaming access and higher-quality video playback.

Creator-Focused Approach

João Davi intends to prioritize a fair revenue split with creators. “I only need money to pay [for] the servers and whoever is working. More than that, it’s like, ‘What I do with this money?’” he said.

Launch Timeline and Beta Access

Spark is expected to launch in March. A sign-up for beta testers will be available early this year. The app has already garnered some investor interest, which could potentially accelerate the development process.
