Acheron
A canvas for each project
Move and resize sessions, or use Tile sessions to put them into an even grid. New terminals join the grid automatically. Undo tiling brings back your previous layout.

Keep the API beside its tests. Leave a deployment in view while you review documentation. Arrange sessions around the work they belong to.

Overview fits the workspace on screen. Zoom changes the view without reflowing terminal text or moving your scroll position. Keep typing, selecting, and scrolling at your chosen scale.
Context beside the work
Give a session a stable name and let generated summaries follow its progress. Open its task history to revisit earlier work, or use notification history to return to an update you missed.

OverseerPlan, assign,
Plan, assign,
and review.
Choose Claude Code, Codex, or Charon as your workspace’s Overseer. Connect the agents it can direct, assign an objective, and review the work and decisions together. Automatic updates are checked for changed output and state before waking Overseer, keeping unchanged sessions out of routine reviews.

With tmux installed, quitting Acheron leaves your shells and agents running. Open it again to reconnect.
Local sessions end if the Mac restarts. A sleeping Mac pauses local work.
Remote work has
its own home.
Connect over SSH and run sessions in tmux on the remote host. They can continue while your laptop is disconnected.
The remote machine needs to stay running.
Check in,
where you are.
The iOS companion connects over SSH to show workspaces and open live terminals. Pair your device to access the same sessions.
Explore features ↗A note on summaries
Summaries are optional. Choose a local model through Ollama or a hosted model through OpenRouter. With a hosted model, terminal output is sent to that provider for analysis.

Send it back for review.
Connect two Claude or Codex sessions. A manager’s completed reply goes to the implementer; the result comes back for review.
See how peer wires work ↗Hand off completed replies
Use matching or mixed agent pairs, locally or over SSH. The relay waits for a completed reply in the session’s own transcript.
Keep the exchange in view
Read the delivery history, inspect pending messages, and pause the wire. A handoff limit bounds each exchange; wires reopen paused after an app restart.

Answer from anywhere.
The Inbox brings approvals, errors, and recently finished work together across projects. Open a session or mark it Done to clear it until new activity arrives. Switch to All activity for the full fleet, and reply in a live SSH terminal or read its output in Glance.

Bring a conversation back when you need it, and open the page you’re working on beside its terminal.
Archive a conversation
Name it, put it away, and find it again in Archived. A running tmux session stays alive. Claude and Codex can resume the exact saved conversation after its process ends.
Stored conversations ↗Browse beside your agents
Open a terminal link in a browser pane, or enter a local development address. Move it around the canvas and return to its saved URL.
