That relay stores everything: channels, messages, repositories, workflows, media, agents, and member identities. Teams can use Block&rsquo;s hosted relay or deploy their own when self-hosting.<\/p><p class=\"wp-block-paragraph\">Every person and AI agent authenticates with a cryptographic identity based on the Nostr protocol, and that identity determines which channels they can see and join. Private discussions stay visible only to the people and agents added to them.<\/p><p class=\"wp-block-paragraph\">Team members create channels for projects, features, or ongoing discussions, then invite colleagues and AI agents into them. <\/p><p class=\"wp-block-paragraph\">Because conversations, Git activity, code reviews, repositories, workflows, and media all live in the same workspace, a project&rsquo;s history stays intact from the first message to the final code change so nobody has to reconstruct it from Slack threads and GitHub comments after the fact.<\/p><p class=\"wp-block-paragraph\">AI agents work inside this same structure as first-class members, not external integrations. Depending on their permissions and tools, they can answer questions, search project history, review code, create patches, run workflows, and coordinate with other agents. <\/p><p class=\"wp-block-paragraph\">Because Buzz is model- and agent-agnostic, teams can run the built-in starter agents or connect agents built on tools like Claude Code, OpenAI Codex, or goose through the Agent Client Protocol (ACP).<\/p><p class=\"wp-block-paragraph\">People still make the final call. Team members decide what to delegate, review what agents produce, and approve changes before anything ships.<\/p><h2 class=\"wp-block-heading\" id=\"h-key-features-of-buzz\">Key features of Buzz<\/h2><p class=\"wp-block-paragraph\">The platform includes channels, direct messages, repositories, workflows, AI agents, media sharing, and search, allowing teams to collaborate without separating conversations from development work.<\/p><h3 class=\"wp-block-heading\">Channels<\/h3><div class=\"wp-block-image wp-block-image aligncenter size-large\"><figure class=\"wp-lightbox-container\" data-wp-context='{\"imageId\":\"6a6c7e09e1b68\"}' data-wp-interactive=\"core\/image\" data-wp-key=\"6a6c7e09e1b68\"><img decoding=\"async\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on--click=\"actions.showLightbox\" data-wp-on--load=\"callbacks.setButtonStyles\" data-wp-on--pointerdown=\"actions.preloadImage\" data-wp-on--pointerenter=\"actions.preloadImageWithDelay\" data-wp-on--pointerleave=\"actions.cancelPreload\" data-wp-on-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/imagedelivery.net\/LqiWLm-3MGbYHtFuUbcBtA\/wp-content\/uploads\/sites\/2\/2026\/07\/1785416429043-0.png\/public\" alt=\"Diagram of a channel-based collaboration workspace with a sidebar channel list, an expanded project channel showing chat, AI agent, and code activity, and three outcome nodes labeled Discuss, Review, and Merge.\"><button class=\"lightbox-trigger\" type=\"button\" aria-haspopup=\"dialog\" data-wp-bind--aria-label=\"state.thisImage.triggerButtonAriaLabel\" data-wp-init=\"callbacks.initTriggerButton\" data-wp-on--click=\"actions.showLightbox\" data-wp-style--right=\"state.thisImage.buttonRight\" data-wp-style--top=\"state.thisImage.buttonTop\">\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewbox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\"><\/path>\n\t\t\t<\/svg>\n\t\t<\/button><\/figure><\/div><p class=\"wp-block-paragraph\">Channels organize conversations around a project, a team, or a shared topic. Open channels are visible to everyone in the community; private channels are visible only to the people and agents added to them.<\/p><p class=\"wp-block-paragraph\">People and AI agents share the same channels, each participating under their own identity and permissions. Adding an agent to a channel works the same way as adding a teammate, and from there it can take on tasks within that project&rsquo;s context.<\/p><p class=\"wp-block-paragraph\">Channels can also become the working home of a feature or Git branch. Discussions, patches, code reviews, CI results, workflow updates, and merge decisions all live in the same channel, so a team can follow a feature from the first conversation to the final merge without losing context. <\/p><p class=\"wp-block-paragraph\">And because that history stays connected, anyone can search it later to see why a decision was made or who &ndash; person or agent &ndash; contributed at each step.<\/p><h3 class=\"wp-block-heading\">Direct messages<\/h3><p class=\"wp-block-paragraph\">Direct messages give a small group a private space to talk without setting up a whole channel. This is useful for a quick one-on-one, sharing something with a specific teammate, or a side conversation that doesn&rsquo;t belong in the wider community. <\/p><p class=\"wp-block-paragraph\">Buzz supports DMs between people and any AI agents that have access to the conversation, and like channels, these messages stay part of the workspace rather than disappearing into a separate app.<\/p><h3 class=\"wp-block-heading\">Repositories<\/h3><div class=\"wp-block-image wp-block-image aligncenter size-large\"><figure class=\"wp-lightbox-container\" data-wp-context='{\"imageId\":\"6a6c7e09ea325\"}' data-wp-interactive=\"core\/image\" data-wp-key=\"6a6c7e09ea325\"><img decoding=\"async\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on--click=\"actions.showLightbox\" data-wp-on--load=\"callbacks.setButtonStyles\" data-wp-on--pointerdown=\"actions.preloadImage\" data-wp-on--pointerenter=\"actions.preloadImageWithDelay\" data-wp-on--pointerleave=\"actions.cancelPreload\" data-wp-on-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/imagedelivery.net\/LqiWLm-3MGbYHtFuUbcBtA\/wp-content\/uploads\/sites\/2\/2026\/07\/1785416449427-0.png\/public\" alt=\"Diagram showing how code changes are sent to a repository, where patches, reviews, and discussions are managed before updates are shared with team members and AI agents, with activity recorded throughout the workflow.\"><button class=\"lightbox-trigger\" type=\"button\" aria-haspopup=\"dialog\" data-wp-bind--aria-label=\"state.thisImage.triggerButtonAriaLabel\" data-wp-init=\"callbacks.initTriggerButton\" data-wp-on--click=\"actions.showLightbox\" data-wp-style--right=\"state.thisImage.buttonRight\" data-wp-style--top=\"state.thisImage.buttonTop\">\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewbox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\"><\/path>\n\t\t\t<\/svg>\n\t\t<\/button><\/figure><\/div><p class=\"wp-block-paragraph\">Repositories put source code in the same workspace where the team already talks and coordinates.

Teams can also build their own for more specialized tasks.<\/p><p class=\"wp-block-paragraph\">Depending on the permissions and tools they&rsquo;re given, agents can answer questions, search conversations, open repositories, create patches, review code, run workflows, create channels, and coordinate with other agents. <\/p><p class=\"wp-block-paragraph\">Buzz also supports voice huddles, where people and agents collaborate in real time.

Teams considering Buzz should keep the platform&rsquo;s current maturity in mind before adopting it for production use.<\/p><p class=\"wp-block-paragraph\">Worth keeping in mind before adopting it for production use:<\/p><ul class=\"wp-block-list\">\n<li><strong>Direct messages on the official Buzz-hosted service are not end-to-end encrypted.<\/strong> Because Block operates the hosted service, it may access direct messages when necessary to operate, secure, or moderate the service, or to comply with legal obligations.<\/li>\n\n\n\n<li><strong>Self-hosting requires managing your own deployment.<\/strong> Organizations that choose to self-host Buzz are responsible for installing, configuring, maintaining, and updating the platform.<\/li>\n<\/ul><h2 class=\"wp-block-heading\" id=\"h-buzz-use-cases\">Buzz use cases<\/h2><p class=\"wp-block-paragraph\">Buzz combines communication, Git repositories, automation, and AI agents in one workspace, which makes it useful for:<\/p><ul class=\"wp-block-list\">\n<li><strong>Coordinating feature development.<\/strong> A dedicated channel per feature or Git branch, where developers and agents discuss requirements, review patches, run workflows, and track progress from idea to merge.<\/li>\n\n\n\n<li><strong>Automating release management.<\/strong> Trigger a workflow on a tagged release to generate notes, coordinate approvals, notify the team, and publish after human review.<\/li>\n\n\n\n<li><strong>Reviewing and maintaining large codebases.<\/strong> Ask an agent to answer questions about the code, review pull requests, suggest patches, or surface related discussions.<\/li>\n\n\n\n<li><strong>Deploying specialized agents.<\/strong> Build or import agents for documentation, research, code review, or task coordination alongside the human team.<\/li>\n<\/ul><p class=\"wp-block-paragraph\"><div class=\"announcement-block announcement-block--important\">\n            <span class=\"announcement-block__heading\">\n                <svg width=\"24\" height=\"24\" viewBox=\"0 0 24 24\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\n                    <path fill-rule=\"evenodd\" clip-rule=\"evenodd\"\n                          d=\"M12 22.5C17.799 22.5 22.5 17.799 22.5 12C22.5 6.20101 17.799 1.5 12 1.5C6.20101 1.5 1.5 6.20101 1.5 12C1.5 17.799 6.20101 22.5 12 22.5ZM13.637 7.65198C13.637 6.74791 12.9041 6.01501 12 6.01501C11.0959 6.01501 10.363 6.74791 10.363 7.65198C10.5335 9.53749 10.875 13.383 10.875 13.383C10.875 14.0043 11.3787 14.508 12 14.508C12.6213 14.508 13.125 14.0043 13.125 13.383V13.38L13.637 7.65198ZM11.9927 15.714C11.3714 15.714 10.8677 16.2177 10.8677 16.839C10.8677 17.4603 11.3714 17.964 11.9927 17.964H12.0073C12.6286 17.964 13.1323 17.4603 13.1323 16.839C13.1323 16.2177 12.6286 15.714 12.0073 15.714H11.9927Z\"\n                          fill=\"#FEA419\"\/>\n                <\/svg>\n                Important\n            <\/span>\n            <p class=\"announcement-block__content\">\n                Teams that rely on mature collaboration platforms with extensive enterprise ecosystems should evaluate whether Buzz&rsquo;s current feature set meets their requirements before adopting it as their primary collaboration platform.\n            <\/p><\/div> <\/p><h2 class=\"wp-block-heading\" id=\"h-how-to-get-started-with-buzz\">How to get started with Buzz<\/h2><p class=\"wp-block-paragraph\">There are two ways to start using Buzz: through Block&rsquo;s hosted service, or by self-hosting it yourself.<\/p><h3 class=\"wp-block-heading\">Using Buzz&rsquo;s hosted service<\/h3><p class=\"wp-block-paragraph\">Buzz&rsquo;s hosted service is the quicker route.
