The problem 🧭

Powerful agents shouldn't be blind.
Visual tools shouldn't spy on you.

Without BuzzAgent 😖

  • ✗ You paste an API key into a VS Code extension that quietly ships telemetry and accounts.
  • ✗ The agent edits files for ten minutes — and you find out what it did by reading git diff afterwards, in a terminal.
  • ✗ "It broke my app" — but the agent never saw your browser, so it fixes blind.
  • ✗ One task at a time, one branch, one waiting human.
  • ✗ Shell commands run first and ask later — or never.

With BuzzAgent 😎

  • ✓ Keys live in the core's own storage — the UI never holds a copy, no telemetry ever ships.
  • ✓ Every file change streams into a live, word-level diff — accept, revert or discuss before it lands.
  • ✓ The agent opens your app in a built-in browser, screenshots it, reads the console — and fixes what it actually sees.
  • ✓ Spawn parallel agents on isolated git worktrees and watch them all from one monitor.
  • ✓ Destructive commands queue in a permission inbox and run only when you say so.

The market splits in two: visual-but-weak assistants locked inside IDEs, and powerful-but-blind terminal agents. BuzzAgent refuses the trade-off — a full visual workbench over the strongest open agent core, running on your machine, calling no server but yours and your provider's. 🔒

See every move. Approve every step. 🎬

Streaming text, tool cards with real arguments, live diffs, console errors surfaced as text the agent can act on. Nothing happens on your machine without a visible trace.

What you get ✨

Everything visual.
Nothing taken away. 🎁

The core does the heavy lifting; the workbench makes it observable, safe and fast.

Streaming code output
💬

Streaming chat that never blinks

Tokens land incrementally with markdown and syntax highlighting — no reflow, no flicker, 60 fps in thousand-message sessions. Inspect every tool call: the exact arguments, the duration, the error if it failed. Never a swallowed spinner.

Code changes
🔀

Diffs you can trust

Real side-by-side git diffs with word-level marks. Review while the agent works — and roll any file back with one click, straight from the panel.

Agent with a browser
🌐

Browser in the loop

Managed headless Chrome — or attach to your real browser over CDP, logged-in profile included. Screenshots and console stream straight into the agent's context, so it fixes what it actually sees.

🌿

Parallel worktrees

Run three agents on three branches at once — isolated git worktrees, one visual monitor. Ship the best, discard the rest. 🧪

🛡️

Permission inbox

Shell commands, file writes, browser control — all wait for your explicit yes. Allow once, always for this tool, or deny. You are the gatekeeper. 🚦

Allow once Deny
🔌

75+ providers, OAuth included

Anthropic, OpenAI, Google, local Ollama — any OpenAI-compatible endpoint. Sign in with Claude Pro or Copilot via OAuth; keys never leave the core.

🧩

Skills, MCP & slash commands

Toggle MCP servers per project, build custom agent modes, run /compact, /undo, /export from the composer.

⌨️

Voice, notifications, queue

Dictate prompts through your local Whisper server, queue tasks while the agent works, get desktop + ntfy pings when a run finishes.

"Finally, an agent UI that shows everything and hides nothing. The permission inbox alone is worth it."

"I run three worktree agents overnight and review the diffs over coffee. That used to be a full workday of babysitting."

"Zero telemetry was the reason I tried it. The browser-in-the-loop is the reason I stayed."

How it works 🛠️

Sixty seconds to your first agent task. ⏱️

1
📁

Pick a project folder

The app starts a supervised agent core bound to your directory — random port, generated password, health-checked. Your files never leave your machine.

2
🔑

Connect a provider

Paste an API key or sign in via OAuth — 75+ models, local Ollama included. Auto-discovery probes the endpoint and confirms it works before you send a thing.

⚡

Describe the task

Watch streaming text, tool cards and diffs arrive live. Approve each step — or queue the next task and let it run.

FAQ ❓

Questions, answered 🙋

🔒 Is it really telemetry-free?⌄

Yes — and verifiably so. Sharing and auto-update channels are force-disabled in config, the audit is public (docs/telemetry-audit.md), and the only network traffic is your local core and the provider you configure.

🔌 Which AI providers are supported?⌄

75+ out of the box: Anthropic, OpenAI, Google, xAI, OpenRouter, local Ollama, and any OpenAI-compatible endpoint. OAuth login for Claude Pro / Copilot-style accounts, plain API keys for everything else.

📦 Do I need to install OpenCode separately?⌄

No. The desktop app ships a supervisor that downloads the pinned core, runs it on a random loopback port with a generated password, health-checks it, and tears it down on exit. One installer, zero terminal.

🗝️ Where does my API key live?⌄

In the core's own credential store (auth.json), written by the core itself. The UI never stores or even sees a second copy.

💻 Which platforms are supported?⌄

Windows 10/11, macOS 12+, and Linux (AppImage / .deb / .rpm). Apple Silicon and Intel both supported.

🆚 How is this different from Cline or Kilo Code?⌄

They are IDE extensions with their own lighter agents and telemetry. BuzzAgent is a standalone desktop app over the full-strength open core — no IDE required, no account, no telemetry, and native extras like worktrees and the browser loop.

💸 What does it cost?⌄

Nothing, ever. MIT licensed — free for personal and commercial use, forever. You pay only your LLM provider directly, at their rates, with no middleman markup.
