Twitter and Block co-founder Jack Dorsey announced a new app on Tuesday called Buzz. Positioned as a direct challenger to established tools like Slack and GitHub, Buzz is a group chat platform designed for the modern workplace, where human employees and their AI agents collaborate in the same conversational spaces.
Dorsey posted on X that Buzz is "model-agnostic, decentralized, self-sovereign, and open source." This product is not merely a side project; according to its official website, Buzz was developed by Dorsey's company Block, which also operates Square, Cash App, Afterpay, and Tidal. The announcement comes at a time when startups and enterprises are increasingly integrating AI agents into their workflows, creating a need for platforms that can seamlessly combine human collaboration with automated tasks.
The Vision Behind Buzz
Buzz enters a market long dominated by Slack, which has become synonymous with workplace communication. However, Dorsey and his team see an opportunity to disrupt that dominance by building a platform from the ground up with AI agents as first-class citizens. The interface resembles Slack, but Buzz offers native tools for managing GitHub projects and interacting with multiple AI agents—all from a single window. This consolidation aims to eliminate the friction of switching between separate apps for chat, code repository management, and AI agent interfaces.
Because Buzz is open source, development teams can customize their own instances to suit specific needs. If a team requires a feature that isn't yet available, they can build and deploy it themselves, as they have full access to the source code. This approach is particularly appealing to organizations that value data sovereignty and want to avoid vendor lock-in. The decentralized nature also means that no single entity controls the network, aligning with Dorsey's long-standing advocacy for open protocols and self-sovereign identity.
Context: Jack Dorsey's Track Record
Jack Dorsey is no stranger to launching ambitious platforms. As co-founder and former CEO of Twitter (now X), he helped shape social media as we know it. He also co-founded Block (formerly Square), which revolutionized mobile payments. His involvement with cryptocurrencies and decentralized technologies is well-documented; he has been a vocal supporter of Bitcoin and decentralized finance. Buzz seems to be a natural extension of his philosophy: an open, interoperable tool that empowers teams rather than locking them into proprietary ecosystems. The platform's name, Buzz, evokes a sense of constant activity, much like a hive of bees, and the bee emoji is central to its branding.
Block's portfolio already includes several products that could integrate with Buzz in the future. Square and Cash App might allow teams to handle payment workflows directly within the chat. Tidal could be used for music collaboration. The possibilities are vast, though Block has not yet announced any specific integrations. The company's history of building developer-friendly tools—Square's APIs, for example—suggests that Buzz will likely offer robust integration options.
The Growing Role of AI Agents in the Workplace
The launch of Buzz reflects a broader industry trend: the rise of AI agents that can perform tasks autonomously, from coding to customer support to data analysis. Startups are increasingly relying on these agents to boost productivity, but managing them across disparate platforms can be chaotic. Employees often need to toggle between Slack for communication, GitHub for code, and separate dashboards for each AI agent. Buzz aims to centralize all of this into one workspace, allowing agents to join channels, respond to queries, and execute tasks just like human colleagues.
This concept is not entirely new. Georgios Konstantopoulos, CTO of venture firm Paradigm, recently unveiled an open source tool called Centaur, which he describes as a "virtual employee" that operates inside Slack via an API. Centaur is designed to let teams self-host for security and control, and it can handle coding and other tasks. Konstantopoulos wrote on X that "there's a lot of room for improvement for agents that live in Slack and can do more work than just coding for teams." Buzz differs from Centaur in that it is a standalone platform rather than an add-on to Slack, giving teams more independence from existing chat tools.
Other companies are also exploring AI-native collaboration. Microsoft has introduced Copilot for Teams, while Google is integrating Gemini into Workspace. However, these solutions are tied to proprietary ecosystems and may not offer the same level of customization or data sovereignty as open source alternatives like Buzz.
Early Stage and Practical Considerations
Despite the buzz (pun intended) around the announcement, the platform is in its early stages. The free desktop app is available now for macOS, Windows, and Linux, and the source code has been uploaded to GitHub. However, Buzz itself cautions that it is "early stages" and probably not yet suitable for porting an entire team over. Early adopters can experiment, provide feedback, and help shape the product's development. The open source community can also contribute by building plugins, integrations, and customizations.
For startups that are already heavily invested in Slack or GitHub, switching to an immature platform may not be practical. But for newer ventures that are building their workflows from scratch—especially those that rely on AI agents—Buzz could be worth investigating. The promise of a decentralized, customizable, and agent-friendly workspace is compelling, especially for teams that value privacy and control over their data.
Security will be a critical factor. Since Buzz is open source and self-hosted, organizations must handle their own security patches and updates, which can be a burden for smaller teams. On the other hand, self-hosting eliminates the risk of data breaches on third-party servers. Block's experience with security in payment processing may lend credibility to Buzz's underlying architecture, but the community will ultimately determine its robustness.
The competition in this space is likely to intensify. Slack has already introduced Slack AI features, and GitHub offers Copilot for code generation. Buzz's unique selling point is its comprehensive integration of these functions into a single, open platform. Whether that is enough to lure users away from entrenched tools remains to be seen. Dorsey's reputation and Block's resources give Buzz a strong foundation, but the path to widespread adoption is long.
In the meantime, developers and tech enthusiasts can download Buzz and explore its potential. The platform's open source nature invites experimentation, and the community's contributions will likely accelerate its maturity. As AI agents become more prevalent, the need for dedicated collaboration platforms will only grow, and Buzz has positioned itself at the forefront of that shift.
