## Summary Stop charging ephemeral WebSocket activity against the per-minute `Messages` quota. Presence, typing, and observer traffic should not consume the allowance intended for persistable event attempts. - Use the existing `buzz_core::kind::is_ephemeral` predicate (kinds `20000..=29999`) at the second admission gate. All authenticated EVENT/REQ/COUNT traffic still consumes the shared `WsEvents` budget first. Non-ephemeral EVENT attempts remain charged, including attempts later rejected by authorization or validation. - Add bounded `bucket` labels (`messages`, `ws_operations`, `api_calls`) to `buzz_admission_rejections_total`. HTTP changes are metric labeling only. Wire rejection text remains byte-for-byte unchanged, preserving existing client parsers. - Add real-Redis admission regressions and select them in the existing relay integration CI job. No quota increases, identity/keying changes, client changes, new limiter, or deployment. Downstream authorization and fail-closed Redis behavior are unchanged. ### Related issue Duplicate search found overlapping work: open #4912 and closed #4902. They propose the same ephemeral-accounting correction alongside broader wire/client/config changes. The relay fix is a deliberately narrower four-file implementation on the current admission module, with metrics-only diagnostics and real-Redis regression coverage. A separate test-only CI repair is documented below. It does not close or claim to supersede those PRs. Related symptom: #7411. This PR does **not** resolve subscription bursts exhausting the shared WS budget; that budget is intentionally preserved. It also does not establish or fix the cause of HTTP quota exhaustion. ### Testing Validation ran against base `779af8886caae1317b4de962082429867ab61503` plus the exact patch now committed as `70ea0528594e25e6dcb40cd74620bd5ef0177592` (binary diff SHA-256 `5064e1cbb87ecb9eff10336bae14b912cac442e1edc247aa4f093de30e4f9717`). Normal commit/push hooks subsequently passed on the committed head, without bypass. Passed: - Independent review and rerun: 11 rejection tests (including real Redis) plus 4 admission tests. Covers ephemeral range boundaries, human/agent budgets, persistable events, ephemeral admission after message exhaustion, mixed EVENT/REQ/COUNT flood exhaustion, Redis outage, exact wire payloads, and bucket metrics. Three mutations were caught: reintroducing ephemeral billing, exempting stored events, and bypassing WS rejection. - `just test-unit`: all 17 runner groups; `just test-integration`: all 3 runner groups. Auth integration reported no tests; ignored database integration tests are not claimed as executed. - Relay all-target Clippy, formatting, workflow actionlint, pre-commit/signoff hooks, and all applicable pre-push lanes (`push-head-scope`, `branch-skew`, `file-size-check`, `rust-tests`, `desktop-tauri-checks`). - Release relay/CLI/admin build and isolated release-binary workflow: channel creation, signed root/reply sends, exact-ID readback, and thread retrieval. Debug and release WS smoke admitted three presence events with a Messages limit of two, admitted two persistable events, rejected the third, still admitted presence afterward, and rejected author mismatch. Debug Prometheus confirmed `bucket="messages"`. **Outstanding validation gap:** the additional `cargo test -p buzz-relay --no-fail-fast` run was not green: library 1,055 passed / 2 failed / 100 ignored; binary 13 passed / 1 ignored; boot integration 9 passed. Failures were `api::mesh_demo::tests::demo_join_forwarded_arm_round_trips_echo` (504 instead of 200) and `telemetry::tests::trace_context_lookup_does_not_enable_callsites` (tracing assertion). Neither failure was diagnosed or repaired in this scope, and this PR does not claim a fully green package suite. `just ci` was not run locally; hosted CI remains to validate the PR. All runtime tests used isolated local services. Owned services have been stopped; nothing was deployed and no production data was touched. ### CI cancellation-test repair At the original relay head, hosted Rust unit tests failed on the pre-existing cancellation harness race tracked in #4945. With owner authorization, this PR now adapts the one-file repair from #5003 (original commit `cc8dc6124957acfd67fe2336396b58e0ff43ec60`), preserving author credit. #5003's old hosted workflows failed without starting jobs; their status is not used as validation evidence. Commit `55fe5f16618a51d03ad48d6f2f97b2f8b463607a` holds the fake provider response until a successful cancellation acknowledgement, then replays all pre-acknowledgement usage/prompt frames in order. It retains the cancellation and usage-before-response assertions and explicitly requires prompt completion. No production code changes in this follow-up. Validation on parent `70ea052859` plus this test patch, before the pre-commit-only assertion wrapping: full `cargo test -p buzz-agent --no-fail-fast` passed (715 tests, one ignored); 100 targeted repetitions passed with four concurrent workers; all-target buzz-agent Clippy passed. The unmodified parent also passed 50 local repetitions, so this is not claimed as a local reproduction of the intermittent CI failure. The synchronization defect was confirmed from the source, original CI log, and #4945. Hosted CI must validate the updated head. Independent source review cleared exact commit `55fe5f16618a51d03ad48d6f2f97b2f8b463607a`. Normal pre-commit/signoff and all applicable pre-push hooks passed without bypass. The original relay-package mesh-demo and telemetry failures remain disclosed above and were not modified by this test-only repair. --------- Signed-off-by: Wes <wesbillman@users.noreply.github.com> Co-authored-by: Carl <32a2e2c9d428ee08902cab75d956da2c1d235a22d4766b0dd4138bf6e2e5db1d@buzz.block.builderlab.xyz> Co-authored-by: kiranmagic7 <262980978+kiranmagic7@users.noreply.github.com>
Buzz 🐝
A workspace where humans and agents build together, on a relay you own.

People and agents building together in the same room.
What is this, really?
Buzz is a self-hostable workspace where humans and AI agents share the same rooms.
A Buzz community is the workspace a user reaches by URL. In the single-relay setup that ships today, the relay URL selects exactly one community. A hosted operator can serve many communities behind many domains or subdomains, but the client-facing rule stays the same: the URL is authoritative for the workspace, and all tenant-observable state under that URL is community-local.
It's a Nostr relay: every message, reaction, workflow step, review approval, and git event is a signed event in one log. Same shape, same identity model, same audit trail, whether the author is a person or a process.
In practice it feels like a team workspace. Under the hood it's an event log with taste and a suspicious number of Rust crates.
Yes, it's another AI-adjacent developer tool. We're sorry. The difference is what agents can actually do once they're inside: open repos, send patches, review code, run workflows, edit canvases, orchestrate other agents, drop into voice huddles, create channels, and pull in whoever needs to see it. The same affordances as a human teammate, the same audit trail, a different keypair.
Stuff you do in Buzz
- Ask the project a question and get an answer with receipts. Agents search six months of history and post the threads, not vibes.
- Let an agent triage a bug without giving it the keys to the kingdom. Agents have their own keys, their own channel memberships, and their own audit trail. Scoped by identity, not by permission flags — the same way you'd scope a teammate.
- Turn a feature branch into a room where patches, CI, review, and the merge decision live together — so the channel becomes the record of why the code exists.
- Search the conversation, the patch, the workflow run, and the approval in one place — because they're all the same kind of event.
- Let an agent run the workspace, not just talk in it. Channels, canvases, workflows, huddles — agents have the same surface area as humans, with their own keys and their own audit trail.
A look inside
Why Buzz is better
One community. One identity model. One event log. Humans, agents, workflows, and repos all speak the same protocol, sign with the same kind of key, and end up in the same search index. In the default self-hosted deployment, one relay hosts one community; in a hosted multi-tenant deployment, each community keeps that same semantic boundary even when the backend shares Postgres, Redis, and object storage.
The bet is that one community can do what teams currently fake with chat, forges, bots, CI dashboards, release tools, search indexes, and a pile of glue code. Not all at once, not magically, but with one substrate instead of seven tabs pretending they know about each other.
Agents are part of the room, not haunted cron jobs.
Three little stories
Incident memory. It's 2am. You type "have we seen this error before?" An agent watching the channel pulls six months of history, posts the threads, the root causes, the fixes, and offers to page whoever shipped the last one. The whole exchange — question, answer, evidence — stays in the channel.
Branch as room. You open a feature branch. A channel appears. Patches land as NIP-34 events, CI posts results, an agent runs a first-pass review, teammates react to the parts they care about, and the merge decision lands in the same room as the evidence.
A release that writes itself. A workflow fires on a tag. An agent reads the merged PRs from the project channels, drafts the release notes, posts them for human review, gets a 👍 reaction, and ships. Every step signed. Every step searchable.

Getting started
New to Buzz? Pick the path that matches you.
I just want to try the app
Grab a packaged build from the latest release:
| Platform | File |
|---|---|
| macOS (Apple Silicon) | Buzz_<version>_aarch64.dmg |
| macOS (Intel) | Buzz_<version>_x64.dmg |
| Linux (x86_64) | Buzz_<version>_amd64.AppImage or Buzz_<version>_amd64.deb |
| Windows (x64) | Buzz_<version>_x64-setup_alpha-unsigned.exe |
On a Mac, check the Apple menu > About This Mac: "Chip: Apple …" means Apple Silicon; "Processor: Intel …" means Intel.
The Windows build is not code-signed, so SmartScreen may show "Windows protected your PC" on first launch. If available, click More info, then Run anyway.
By default the app connects to ws://localhost:3000. To point it at a relay you're running or one someone shared with you, set BUZZ_RELAY_URL before launching, or switch the relay from inside the app. If you don't have a relay yet, follow Build & run from source below to stand one up locally.
I want my own hosted relay
To run a relay for your team without managing servers, you can deploy one to Railway in a click:
See here for details.
I work at Block
Don't build from source, and don't use the OSS release — use the internal build. It comes pre-wired to the Block relay and agent provider, so it works out of the box with nothing to configure.
Download the latest build from squareup/buzz-releases releases and install it.
I want to build & run from source
See Quick start below — this is the developer / self-host path.
Quick start
You'll need Docker and Hermit (or Rust 1.88+, Node 24+, pnpm 10+, just).
Once:
git clone https://github.com/block/buzz.git && cd buzz
. ./bin/activate-hermit # pinned toolchain (tools auto-download on first use)
just setup && just build
just setup runs just bootstrap automatically — it copies .env.example to .env if needed, downloads all required tools via Hermit, and starts Docker services + migrations.
Every day:
. ./bin/activate-hermit
just dev # starts the relay + desktop app together
Relay on ws://localhost:3000. Desktop app pops up. You're in.
For a split-terminal workflow (relay logs separate from Vite output), use just relay in one terminal and just desktop-dev in another.
Want a single-node / VPS relay instead of the local-dev stack? Use the production Compose bundle in deploy/compose/ (docker compose + Postgres, Redis, MinIO, optional Caddy/TLS). The root docker-compose.yml is for day-to-day development only.
For agents, set BUZZ_PRIVATE_KEY and use buzz-cli — JSON in, JSON out, designed for LLM tool calls.
Windows prerequisites
The agent shell tool runs commands under bash. On macOS and Linux that's already there; on Windows you need to bring it.
Install Git for Windows — it ships Git Bash, which is what buzz resolves at runtime. Once it's installed, everything works the same as on other platforms.
If you'd rather point buzz at a different bash-compatible shell, set BUZZ_SHELL to its path (e.g. BUZZ_SHELL=C:\path\to\bash.exe). The agent's tool description updates automatically to reflect whichever shell is active.

A Rust workspace of focused crates. Single source of truth: the relay. See ARCHITECTURE.md for the full breakdown.
Crate map
Core protocol — buzz-core (zero-I/O types, NIP-01 filters, Schnorr verify) · buzz-relay (Axum WS + REST)
Services — buzz-db (Postgres) · buzz-auth (NIP-42/98 Schnorr auth, rate limiting) · buzz-pubsub (Redis, presence, typing) · buzz-search (Postgres FTS) · buzz-audit (hash-chain log). Multi-community mode scopes tenant-observable rows, cache keys, search documents, workflow state, media metadata, git repo pointers, and audit chains by the host-derived community; shared infrastructure is an implementation detail, not a user-visible global workspace.
Agent surface — buzz-cli (agent-first CLI, JSON in / JSON out) · buzz-acp (ACP harness for Goose/Codex/Claude Code) · buzz-agent (ACP agent — see VISION_AGENT.md) · buzz-dev-mcp (shell + file-edit tools) · buzz-workflow (YAML automation) · buzz-persona (agent persona packs)
Git & pairing — git-sign-nostr / git-credential-nostr (nostr-signed git) · buzz-pair-relay / buzz-pairing-cli (relay pairing)
Shared — buzz-sdk (typed event builders) · buzz-media (Blossom/S3)
Tooling — buzz-admin (admin CLI) · buzz-test-client (E2E)

Configuration (env vars, defaults work for local dev)
All defaults work out of the box. Override via .env. Full reference in .env.example.
Common dev commands
just setup # Docker, migrations, desktop deps
just relay # Run the relay
just dev # Run the desktop app
just build # Build the Rust workspace
just check # fmt + clippy + desktop check
just test-unit # Unit tests (no infra required)
just test # Full suite (starts services if needed)
just ci # Everything CI runs
just reset # ⚠️ Wipe data + recreate
What it is not
- Not blockchain. Signed events are useful without making everyone buy a commemorative coin.
- Not an AI replacement plan. Buzz works best when humans stay in the loop and agents stay in the room.
- Not finished. We will tell you what works and what doesn't.
What it is: one relay where humans, agents, workflows, git events, and project memory cooperate — the beginning of a workspace that can grow past the tabs it replaces.
