v1.0 — Claude on Perch, day one

Terminal You Will Love.

toowl · pronounced /tuːl/ — like “tool”. The owl is just here for moral support.

A GPU-fast desktop terminal and a tmux-style remote client in one binary — with daemon-backed workspaces and Claude on the Perch.

First feather on the Perch

Claude on the Perch.

Open the Perch (⌘B). The Claude Feather is already there — your Claude Code sessions, resumable, crash-recoverable, palette-integrated. No setup, no detour through a browser. Bring your own claude binary; the Feather handles the rest.

Resume any session

Every Claude Code conversation in this directory shows on the Perch, one click away.

Crash recovery, built in

When Claude goes down mid-task, the Feather detects it and offers a one-key restart. Your context survives.

Palette-integrated

Cmd-Shift-P opens Claude commands alongside terminal actions. One muscle memory, two superpowers.

Breakthroughs, not bullet points

The handful of things toowl does that no other terminal puts in one binary.

GPU-fast, idle-quiet

A wgpu renderer that draws only when something changes — <80ms cold start, ~80MB at rest, and a cursor that glides at your display's refresh rate but costs nothing when you're reading.

Daemon-backed workspaces

Named workspaces are owned by toowld, not the window. Close the window to detach; reopen to reattach — sessions keep running. Local or remote, same UI with an @host badge.

Two clients, one binary

The same binary is a GPU desktop app on your laptop and a tmux-style crossterm client over SSH — talking to the daemon over a Unix socket, SSH-stdio, or WebSocket.

Claude on the Perch

Open the sidebar and the Claude Feather is already there: your Claude Code sessions, resumable and crash-recoverable, integrated into the command palette. No browser detour.

One daemon. Every client.

Your sessions live in the daemon, not the window.

Attach from the desktop app, a tmux-style TUI over SSH, or a browser — local or across the world, same UI. One daemon per host owns your workspaces; any client attaches over a transport.

Clients

  • Desktop GUI · wgpu, native chrome
  • TUI client · crossterm, over SSH
  • Browser · roost-web, scoped URL

Transport

  • Unix socket
  • SSH-stdio
  • WebSocket / WSS
