Jack Dorsey, the co-founder of Twitter and Block, announced on Tuesday a new group chat platform called Buzz. Positioned as a direct competitor to Slack and GitHub, Buzz is designed for teams that rely on both human workers and AI agents to collaborate in a single workspace. Dorsey shared the news on X, describing Buzz as “model-agnostic, decentralized, self-sovereign, and open source.” The platform was built by Dorsey’s company Block, which also operates Square, Cash App, Afterpay, and Tidal.
What is Buzz?
Buzz is a group chat platform that brings humans and AI agents into the same conversations. It looks much like Slack, with channels, direct messages, and integrated tools, but its key differentiator is native support for AI agents. These agents can be assigned tasks, join channels, and collaborate with human team members on software development, project management, and other workflows. The platform is model-agnostic, meaning it can work with various AI models—including those from OpenAI, Anthropic, and open-source alternatives—giving teams the flexibility to choose the best AI for their needs.
Another critical feature is that Buzz is decentralized and self-sovereign. Teams can host their own instance of Buzz on their own servers, ensuring full control over data and security. This is particularly appealing for enterprises that require strict data governance and compliance. Being open source, the source code is fully available on GitHub, allowing developers to modify and extend the platform as needed. The free desktop app is currently available for macOS, Windows, and Linux, and the code has been uploaded to GitHub for community contributions.
Why Buzz Matters
The rise of AI agents in the workplace has created a new challenge: how to integrate these digital workers into existing communication tools. Many teams still rely on Slack for chat, GitHub for code management, and separate AI tools for automation. Buzz aims to unify these disparate systems into one cohesive interface. By merging chat, project management, and AI agent orchestration, it reduces context switching and simplifies collaboration.
The open-source nature of Buzz gives teams the ability to customize the platform. If a team needs a specific integration or workflow, they can build it and deploy it on their own instance. This level of control is not possible with closed, proprietary platforms like Slack, which limit customization to what the company provides via APIs and plugins. For organizations that prioritize flexibility and autonomy, Buzz offers a compelling alternative.
Competitors in the AI-Native Workspace
Dorsey is not alone in pursuing an AI-native alternative to Slack. Georgios Konstantopoulos, partner and CTO at Paradigm, recently unveiled a similar open-source product called Centaur. Konstantopoulos described Centaur as a “virtual employee” that runs either inside of Slack or via an API. He emphasized that there is “a lot of room for improvement for agents that live in Slack and can do more work than just coding for teams.” Centaur, like Buzz, is open-source and designed to be self-hosted for security and control.
Other startups are also exploring this space, developing platforms that natively integrate AI agents into workplace communication. While Slack itself has introduced AI features, these are often add-ons rather than core to the user experience. Buzz and Centaur represent a new wave of tools that put AI agents at the center of collaboration, rather than as peripheral tools. For newer startups that are building their tech stack from scratch and already rely heavily on AI agents, these platforms could be more attractive than retrofitting old habits onto Slack.
Challenges and Early Stage
Despite its promise, Buzz is in its “early stages,” as the team itself admits. The app is available as a free desktop download, but it may lack the maturity and reliability that established platforms like Slack offer after years of development. Potential users should be cautious about migrating their entire team to Buzz immediately. The platform may have bugs, missing features, or performance issues that only surface in production environments.
However, the open-source community can help accelerate development. With the code on GitHub, developers can contribute fixes, features, and integrations. This community-driven approach can lead to rapid iteration and improvement, especially if Buzz gains traction among early adopters in the tech and startup communities. The decentralized nature also means that even if Block stops maintaining the core project, the open-source community could fork it and continue development independently.
Jack Dorsey’s Vision
Jack Dorsey has long been an advocate for open standards, decentralization, and self-sovereignty. His previous projects, such as the decentralized social media protocol Bluesky and his work on Bitcoin, reflect this philosophy. Buzz fits neatly into this worldview: a tool that reduces dependency on centralized tech giants like Slack (owned by Salesforce) and GitHub (owned by Microsoft). Dorsey’s statement on X emphasized that Buzz is built to “reduce our dependency on slack and github,” highlighting his desire to create alternatives that give users more control over their digital tools.
Block, the company behind Buzz, has a diverse portfolio of fintech and tech products. Square revolutionized payment processing, Cash App became a popular peer-to-peer payment service, and Tidal offers high-fidelity music streaming. By adding a workplace communication platform, Block is entering a new competitive arena. The timing is strategic: as AI agents become more prevalent in software development and operations, the demand for native AI integration in chat tools will likely grow.
Implications for the Workplace
The emergence of platforms like Buzz signals a shift in how teams will collaborate in the future. AI agents are no longer just chatbots that answer questions; they are becoming active participants in workflows—writing code, managing projects, analyzing data, and even making decisions. To fully leverage these capabilities, communication tools need to evolve from simple messaging apps to full-fledged collaboration hubs that treat AI agents as first-class citizens.
Buzz’s open-source and self-hosted model also addresses growing concerns about data privacy and vendor lock-in. Enterprises that handle sensitive data may prefer to keep everything on-premises rather than relying on cloud-based Slack or Teams. By offering a self-hosted solution, Buzz gives these organizations the control they need to comply with regulations like GDPR, HIPAA, or internal security policies.
The platform’s ability to integrate GitHub management directly into chat is another key advantage. Developers often toggle between Slack and GitHub to discuss code reviews, issues, and pull requests. Buzz brings these activities into one window, potentially streamlining development workflows. Combined with AI agents that can automatically triage issues, suggest code fixes, or run CI/CD pipelines, the platform could significantly boost developer productivity.
As Buzz develops, its success will depend on adoption by early users and the vibrancy of its open-source community. If it manages to build a loyal user base and attract contributions, it could become a significant player in the workplace communication market. For now, Buzz is an exciting experiment that reflects the changing landscape of work, where humans and AI agents collaborate side by side. Its free availability and open-source license make it accessible to anyone willing to test a new tool that promises to reshape team collaboration.”
