AGENTIC DEVELOPMENT ENVIRONMENT · macOS

Every agent.
Every worktree.
One window.

Run parallel agents in terminal or chat, keep every worktree in context, review with CI evidence, and ship from one native macOS workspace, on every Mac you pair.

AGENTS01

Hand the work to an agent.

Any ACP agent runs in a chat pane beside the code it is changing, in the same window as the terminal, the editor, and the review.

  • Pick the model, thinking level, and permission mode per session.
  • Plans, tool calls, and verdicts render inline as the agent works.
  • Live badges show which agents need your attention.
  • Install any agent from the official ACP Registry alongside the built-ins.

TERMINAL02

Run a real terminal beside everything else.

Terminal tabs are built on libghostty, so the TUIs you already live in render exactly as they should. Agent sessions, editors, and previews open as tabs in the same pane.

  • Tabs, sessions, and scroll positions stay with the worktree and survive reconnects.
  • SSH projects open like local ones, with agents running on the remote host.
  • Approval prompts and completion notifications reach you, even on your phone.

UNDERSTAND03

Understand before you change.

Read code beside its rendered output, then make the next change.

  • Tree-sitter and LSP make the editor useful, not ornamental.
  • Markdown, Mermaid, and file actions live beside the code.
  • Visual, binary, and LFS changes stay reviewable in context.

REVIEW04

Review without the round-trip.

Turn feedback into the next agent action while the evidence is still attached to the code.

  • Review local work or hosted pull requests side by side.
  • Comment anywhere, then let an agent reply and resolve.
  • Keep CI, test evidence, and revisions continuous through rebases.

SHIP05

Ship the branch with its review state.

Keep the decisions, review state, and next handoff alongside the branch.

  • Stage hunks and draft commits, pull requests, or merge requests.
  • See merge readiness and queues before the final handoff.
  • Optional git-gud support when the work needs a stack.

ANYWHERE06

Pick up from any Mac you own.

Alas instances on your network find each other and pair. Your other Macs' worktrees and agents show up in the sidebar, natively, with no SSH and no Remote Login.

  • Bonjour discovery, pairing approved inside Alas, peers bound to verified keys.
  • Start a worktree and a session on a peer, picking agent, model, and effort.
  • Follow transcripts live, take over with one writer at a time, and drive a peer's consoles under an explicit lease.

The workspace gets out of your way.

EVERYTHING AROUND THE LOOP

Pluggable

Install plugins from the alas-plugins catalog or bring your own. JavaScript plugins add tabs, panels, commands, and context, like Kanban and Agent Usage, with permissions approved up front.

Design it visually

Agents show sandboxed HTML mockups inline in the transcript and ask you to pick from a native card.

On-device AI

Apple Intelligence or a local Qwen model names worktrees, summarizes sessions, drafts commits and PR summaries, and explains conflicts, without leaving the Mac.

Orchestrate agents

Agents delegate to child sessions on other agents and models, then wait on, read, and interrupt them over CLI or MCP.

Schedules

Run scripts or agents by interval or time of day, optionally in a fresh worktree, with run history and reports.

Workspaces & checkpoints

Multi-repo Workspaces, plus a checkpoint before every prompt that you can restore from the transcript.

Work anywhere

The phone hub gathers every paired Mac. Take over any session from your phone, and approve prompts from wherever you are.

Context stays put

Tabs, sessions, scroll positions, closed-tab reopening, resume, and directional navigation.

Bring the whole agent loop into one window.

Open a project, hand off work, review it, and ship from the same window.
