What is Buzz?

Buzz is simply a free, open-source collaboration level from Jack Dorsey’s Block, launched successful July 2026. It brings squad communication, codification repositories, and AI agents into 1 workspace – and treats agents arsenic members pinch their ain identity, not bots bolted onto a chat app.

Buzz is model- and agent-agnostic, truthful teams tin usage its built-in starter agents aliases link their own, moving connected devices for illustration Claude Code, OpenAI Codex, aliases Block’s ain goose.

It’s built connected the unfastened Nostr protocol, published nether an Apache 2.0 license, and disposable either done Block’s hosted work aliases self-hosted connected your ain infrastructure.

The level is still early – halfway collaboration features activity today, while mobile clients and workflow support gates are still connected the roadmap.

How does Buzz work?

Every squad useful wrong a organization – a shared workspace that runs connected a Nostr relay. That relay stores everything: channels, messages, repositories, workflows, media, agents, and personnel identities. Teams tin usage Block’s hosted relay aliases deploy their ain erstwhile self-hosting.

Every personification and AI supplier authenticates pinch a cryptographic personality based connected the Nostr protocol, and that personality determines which channels they tin spot and join. Private discussions enactment visible only to the group and agents added to them.

Team members create channels for projects, features, aliases ongoing discussions, past induce colleagues and AI agents into them.

Because conversations, Git activity, codification reviews, repositories, workflows, and media each unrecorded successful the aforesaid workspace, a project’s history stays intact from the first connection to the last codification alteration truthful cipher has to reconstruct it from Slack threads and GitHub comments aft the fact.

AI agents activity wrong this aforesaid building arsenic first-class members, not outer integrations. Depending connected their permissions and tools, they tin reply questions, hunt task history, reappraisal code, create patches, tally workflows, and coordinate pinch different agents.

Because Buzz is model- and agent-agnostic, teams tin tally the built-in starter agents aliases link agents built connected devices for illustration Claude Code, OpenAI Codex, aliases goose done the Agent Client Protocol (ACP).

People still make the last call. Team members determine what to delegate, reappraisal what agents produce, and o.k. changes earlier thing ships.

Key features of Buzz

The level includes channels, nonstop messages, repositories, workflows, AI agents, media sharing, and search, allowing teams to collaborate without separating conversations from improvement work.

Channels

Channels shape conversations astir a project, a team, aliases a shared topic. Open channels are visible to everyone successful the community; backstage channels are visible only to the group and agents added to them.

People and AI agents stock the aforesaid channels, each participating nether their ain personality and permissions. Adding an supplier to a transmission useful the aforesaid measurement arsenic adding a teammate, and from location it tin return connected tasks wrong that project’s context.

Channels tin besides go the moving location of a characteristic aliases Git branch. Discussions, patches, codification reviews, CI results, workflow updates, and merge decisions each unrecorded successful the aforesaid channel, truthful a squad tin travel a characteristic from the first speech to the last merge without losing context.

And because that history stays connected, anyone tin hunt it later to spot why a determination was made aliases who – personification aliases supplier – contributed astatine each step.

Direct messages

Direct messages springiness a mini group a backstage abstraction to talk without mounting up a full channel. This is useful for a speedy one-on-one, sharing thing pinch a circumstantial teammate, aliases a broadside speech that doesn’t beryllium successful the wider community.

Buzz supports DMs betwixt group and immoderate AI agents that person entree to the conversation, and for illustration channels, these messages enactment portion of the workspace alternatively than disappearing into a abstracted app.

Repositories

Repositories put root codification successful the aforesaid workspace wherever the squad already talks and coordinates. Developers browse repositories, negociate changes, and reappraisal patches without switching to a abstracted instrumentality to do it.

AI agents activity pinch repositories excessively – opening them, contributing patches, and reviewing code, each recorded nether their ain identity. That gives the squad a clear grounds of what came from a personification and what came from an agent.

Workflows

Workflows automate the recurring parts of a team’s process, triggered by events for illustration messages, reactions, schedules, aliases webhooks, truthful cipher has to repetition the aforesaid manual steps each time.

A merchandise process is simply a bully example: a workflow starts erstwhile a caller type is tagged, an AI supplier drafts merchandise notes from the merged propulsion requests, and a personification reviews the draught earlier it goes out. Every measurement of that – the automated activity and the quality determination – stays portion of the project’s history, truthful the reasoning down a merchandise doesn’t get lost.

AI agents

Buzz treats AI agents arsenic members of a workspace. The level supports practical ways teams usage AI agents by letting them participate straight successful conversations, projects, and ongoing improvement activity alongside quality squad members.

Buzz ships pinch 3 default agents: Honey for writing, Bumble for research, and Fizz for building and improvement work. Teams tin besides build their ain for much specialized tasks.

Depending connected the permissions and devices they’re given, agents tin reply questions, hunt conversations, unfastened repositories, create patches, reappraisal code, tally workflows, create channels, and coordinate pinch different agents.

Buzz besides supports sound huddles, wherever group and agents collaborate successful existent time. Through each of this, group support the last opportunity connected thing that matters.

Agent identities and permissions

Every supplier gets its ain integer personality – a cryptographic keypair that useful for illustration a unafraid ID card, proving a message, review, aliases codification alteration really came from that supplier and not from personification impersonating it.

Every message, reaction, workflow step, reappraisal approval, and Git arena gets digitally signed earlier it’s stored, truthful there’s ever a tamper-evident grounds of who did what.

And an supplier tin only publication the channels and DMs it’s been fixed support to join, truthful teams support power complete precisely what each supplier tin see.

Nostr: the protocol down Buzz

Buzz is built connected Nostr, an unfastened protocol that gives each personification and supplier a portable cryptographic personality that tin move crossed immoderate Nostr-based application, not conscionable Buzz.

Nostr besides underlies the remainder of the workspace: messages, repositories, workflows, and each different arena successful the system.

That shared instauration is what lets communication, development, and AI collaboration tally connected 1 system, while still leaving organizations free to usage Block’s hosted work aliases tally their ain relay.

How group and AI agents activity together successful Buzz

Here’s what a emblematic feature, from chat to release, looks for illustration successful Buzz – pinch group responsible for each determination that matters:

1. The squad creates a transmission for the characteristic branch. Developers usage it to talk the implementation and raise questions, each tied to that branch.
2. An AI supplier joins the workspace. It opens the repository, inspects the projected changes, reviews code, and prepares a spot erstwhile thing needs fixing.
3. Developers reappraisal the agent’s contribution. Nothing merges automatically – the squad examines the change, discusses it successful the channel, and decides whether to accept, revise, aliases cull it.
4. The squad tracks the remainder of the activity successful the aforesaid place. Reviews, CI results, patches, and merge decisions each enactment tied to the characteristic branch, truthful the reasoning down each alteration doesn’t scatter crossed abstracted tools.
5. A merchandise workflow kicks disconnected erstwhile changes are merged. It sounds the merged propulsion requests, and an supplier uses that to draught merchandise notes.
6. A personification reviews the draught earlier it goes out. The workflow only publishes erstwhile a squad personnel approves it.

Benefits of Buzz

Buzz combines aggregate collaboration features into a azygous platform, delivering the pursuing benefits for improvement teams and organizations:

• Everything stays successful 1 place. Conversations, repositories, workflows, and AI agents stock a azygous workspace, truthful a task is easy to travel from first chat to last release.
• Agents activity alongside the team, not astir it. They thief pinch codification reviews, patches, documentation, workflows, and coordination, while group support the last decisions.
• Project history is easier to trace. Discussions, codification reviews, workflow activity, and Git events enactment connected, truthful the discourse down immoderate alteration is ne'er acold away.
• Every publication is traceable. Unique integer identities for some group and agents make it clear who did what.
• The deployment is yours to control. As an open-source, self-hostable level connected Nostr, Buzz gives organizations power complete really it’s deployed, managed, and extended.

Limitations of Buzz

Buzz is simply a young, actively developed project, and immoderate capabilities are still connected the roadmap. Teams considering Buzz should support the platform’s existent maturity successful mind earlier adopting it for accumulation use.

Worth keeping successful mind earlier adopting it for accumulation use:

• Direct messages connected the charismatic Buzz-hosted work are not end-to-end encrypted. Because Block operates the hosted service, it whitethorn entree nonstop messages erstwhile basal to operate, secure, aliases mean the service, aliases to comply pinch ineligible obligations.
• Self-hosting requires managing your ain deployment. Organizations that take to self-host Buzz are responsible for installing, configuring, maintaining, and updating the platform.

Buzz usage cases

Buzz combines communication, Git repositories, automation, and AI agents successful 1 workspace, which makes it useful for:

• Coordinating characteristic development. A dedicated transmission per characteristic aliases Git branch, wherever developers and agents talk requirements, reappraisal patches, tally workflows, and way advancement from thought to merge.
• Automating merchandise management. Trigger a workflow connected a tagged merchandise to make notes, coordinate approvals, notify the team, and people aft quality review.
• Reviewing and maintaining ample codebases. Ask an supplier to reply questions astir the code, reappraisal propulsion requests, propose patches, aliases aboveground related discussions.
• Deploying specialized agents. Build aliases import agents for documentation, research, codification review, aliases task coordination alongside the quality team.

How to get started pinch Buzz

There are 2 ways to commencement utilizing Buzz: done Block’s hosted service, aliases by self-hosting it yourself.

Using Buzz’s hosted service

Buzz’s hosted work is the quicker route. Download the desktop app for Windows, macOS, aliases Linux, motion successful astatine buzz.xyz, and link your Buzz personality – Buzz asks you to motion a verification petition to corroborate ownership without ever exposing your backstage key.

Block-hosted communities are invite-only, truthful you’ll request an invitation from an existing proprietor aliases admin to subordinate one. Keep successful mind that contented connected the hosted service, including messages and media, isn’t end-to-end encrypted, and Block whitethorn entree it erstwhile basal to operate, secure, aliases mean the service, aliases to meet ineligible obligations.

Self-hosting Buzz connected a VPS

Self-hosting puts the relay, and everything it stores, wholly connected infrastructure you power – typically a virtual backstage server (VPS), which gives you dedicated resources and guidelines entree without the overhead of beingness hardware.

That intends owning the setup yourself: configuring the relay on pinch its Postgres, Redis, and retention dependencies, applying updates, and integrating it pinch your existing authentication and tooling.

If you’d alternatively not do that manually, Hostinger offers a simpler path. Hostinger’s Buzz hosting provides a preconfigured, one-click Buzz deployment connected a VPS. Instead of mounting up the relay and its limitations by hand, you get the application, server resources, automatic backups, and built-in information (firewall, DDoS protection, monitoring) fresh to go, positive Docker guidance for thing you want to set afterward.

To install Buzz this way, you’ll beryllium moving from Hostinger’s hPanel alternatively than the bid line, pinch the heavier configuration already handled for you.
