Announced by Dorsey on X, Buzz is model-agnostic, decentralized, and runs on the Nostr protocol, offering features such as channels, threads, Git integration, and cryptographic identities for users and AI agents. The platform is released under the Apache 2.0 license and can be self-hosted or used via Block's hosted version.", "body_md": "Jack Dorsey’s Block has unveiled a new platform named Buzz describing it as an open-source collaboration platform that lets employees and AI agents work together in the same digital workspace.\n\nThe move comes amid the company looking to reduce its dependence on tools like Slack and GitHub. The platform’s launch, announced by Block co-founder Jack Dorsey on X on Tuesday, was described as “a new groupchat for teams of people and agents of all sizes.”\n\nAccording to Dorsey, Buzz is model-agnostic, decentralized, self-sovereign and open source, reflecting Block’s push to build collaboration tools that are not tied to a single AI provider or centralized platform.\n\n## How is the platform different?\n\nBuzz is not like traditional workplace chatbots that respond to prompts, instead it treats AI agents as active participants. They can jump into discussions, look over code, execute pre-approved workflows and collaborate with human colleagues on projects.\n\nThe platform offers familiar workplace features like channels, threads, direct messaging, voice, media sharing and collaborative workspaces, plus developer [tools like code repositories](https://thecoinheadlines.com/tech-and-ai/jack-dorseys-spiral-moves-into-ai-hires-core-goose-engineers/article-25317/) and Git integration.\n\nEach user, human or AI, has a unique cryptographic identity with its own permissions and history of activity. That means companies can dictate exactly what each AI agent is allowed to access, and maintain a detailed log of everything it does.\n\nBuzz runs on Nostr, a protocol for decentralised communications where activity is recorded as cryptographically signed events. Teams can store messages, code commits, workflow approvals, and project conversations in a searchable audit log, making it easier to see how work progresses over time.\n\nThe platform is built to work with AI agents powered by many models, not just one provider. It supports frameworks such as Claude Code, Codex and Block’s own Goose and allows businesses to connect internal databases, codebases, file systems and other enterprise tools.\n\nCompanies have the option of using Block’s hosted version of Buzz, or deploying it on their own infrastructure, giving them more control over their data, AI agents and communications. The software is released under the Apache 2.0 open source license.\n\n## Buzz debuts with core collaboration features\n\nBuzz’s first version includes channels and threads, direct messages, collaborative canvases, media sharing, desktop apps, search and workflow automation, and early Git integration. Mobile apps, expanded voice capabilities and approval workflows will be included in future updates.\n\nFor Block, Buzz is more than just a replacement for workplace messaging software.\n\nUltimately, the company wants to bring together a number of tools that teams are using today separately, including chat, code hosting, workflow automation, search and software development, into a single workspace where both people and[ AI agents](https://thecoinheadlines.com/crypto/gomining-takes-aim-at-jack-dorseys-square-with-bitcoin-native-payments-platform/article-23041/) can work together.\n\nThe launch comes as businesses are increasingly looking for ways to bake AI into their daily work, rather than just use it as a stand-alone assistant. By giving AI agents identities of their own, and having them work alongside employees, Block is betting the future workplace will view AI as just another team member.\n\nThe company is trying to position itself with Buzz as the open-source alternative to existing workplace collaboration platforms, providing organisations with a single place to manage conversations, code, workflows and AI-powered collaboration.", "url": "https://wpnews.pro/news/jack-dorseys-block-launches-buzz-to-take-on-slack-and-github", "canonical_source": "https://thecoinheadlines.com/crypto/jack-dorseys-block-launches-buzz-to-take-on-slack-and-github/article-26850/", "published_at": "2026-07-21 22:39:31+00:00", "updated_at": "2026-07-22 07:35:41.451673+00:00", "lang": "en", "topics": ["ai-agents", "developer-tools"], "entities": ["Block", "Jack Dorsey", "Slack", "GitHub", "Nostr", "Claude Code", "Codex", "Goose"], "alternates": {"html": "https://wpnews.pro/news/jack-dorseys-block-launches-buzz-to-take-on-slack-and-github", "markdown": "https://wpnews.pro/news/jack-dorseys-block-launches-buzz-to-take-on-slack-and-github.md", "text": "https://wpnews.pro/news/jack-dorseys-block-launches-buzz-to-take-on-slack-and-github.txt", "jsonld": "https://wpnews.pro/news/jack-dorseys-block-launches-buzz-to-take-on-slack-and-github.jsonld"}}
