<h1>A crew of coding agents, <br><span>on all your Macs.</span></h1>
<p class="lede">byre runs Claude Code, Codex and Antigravity side by side on one Mac, each on its own branch and worktree, with a lead agent that watches them all and tells you what needs you. Pick up from whichever Mac you're at.</p>
<a class="download" href="https://dl.byre.run/byre.dmg">Download for macOS</a>
</header>

<h2>What it does</h2>
<ul class="features">
<li class="hero"><h3>One server, every Mac</h3><p>The agents run on one Mac that stays on, such as a Mac mini in a closet. Open byre on your laptop, your desk Mac, or all of them at once: each shows the same tasks, questions and transcripts live. Close the laptop and the agents keep working.</p></li>
<li class="wide purple"><h3>Every server, every project</h3><p>Your servers sync through iCloud, so a new Mac finds them on first launch. Switch between servers in one window, each with as many projects as you like and its own colour.</p></li>
<li class="green"><h3>Tasks</h3><p>Every task gets its own git worktree, branch and port block. Talk to its agent in a live transcript, even mid-turn.</p></li>
<li class="orange"><h3>Lead agent</h3><p>One long-running agent watches every task, points you at what needs you, and starts, messages, merges or discards tasks when you ask.</p></li>
<li class="wide red"><h3>Questions, not interruptions</h3><p>When an agent needs a decision, it lays out the options and recommends one. Pick an answer in the inbox or right from the notification, and the agent carries on.</p></li>
<li class="wide cyan"><h3>Cross-vendor reviews</h3><p>Every turn that changes files is reviewed by the other vendor's model. The agent fixes the findings it agrees with on its own and says why it skips the rest; you can overrule any of them with a click.</p></li>
<li><h3>One-click merge</h3><p>The agent merges main in and resolves conflicts, then byre squashes, pushes and closes the task.</p></li>
<li class="green"><h3>Snapshots and forks</h3><p>Step through a task's snapshots, diff any of them, and fork a new task from any one, conversation included.</p></li>
<li class="orange"><h3>Teams and workflows</h3><p>Agents spawn subtasks or share a worktree as a team. Workflows chain stages with fan-out and fan-in.</p></li>
<li class="purple"><h3>Hands on your Macs</h3><p>Agents can see and drive the Mac byre runs on, and the Macs you have the app open on, when a task needs it.</p></li>
</ul>

<h2>Getting started</h2>
