Compare
A conductor, not a wrapper.
Plenty of tools put a UI around parallel Claude Code sessions. Loom adds the parts that matter once those sessions run for hours: recovery, verification, and a full workspace.
The difference
What tabs alone cannot do.
Real TUIs, not transcripts
Loom runs six real Claude Code CLI sessions on native PTYs inside a WebGL terminal. Click into any pane and type. It is the same TUI you already use, with tabs, splits, search, and true color, not a re-rendered chat log.
Recovery that never blinks
Loom answers permission prompts by pressing only the safe affirmative, nudges drifting sessions, relaunches exited CLIs, and rotates pooled Claude accounts when a usage limit hits. Six sessions, none of them stalled.
Verification before done
A session saying it is finished is not the same as the work being finished. Loom re-checks every task before it counts, marks finished slots, and catches premature done.
Credit where it is due
Many Claude Code wrapper UIs are genuinely good at what they set out to do: spawn a few sessions, give each one a pane, and let you flip between them. If all you need is an afternoon of supervised parallel work, a lightweight wrapper may serve you well, and some are simpler to pick up than Loom.
Loom is built for the next step: missions that keep moving when you are not watching. A Conductor, a bring-your-own-key reasoning model from any of 12+ providers or a fully local one, plans your goal into a DAG of tasks, dispatches them across the fleet, watches every terminal, and steers. Live activity strips show what each session is doing at a glance. That is the difference between a window manager and mission control.
Open to the last line
Loom is Apache-2.0 and the entire app is public on GitHub. There is no telemetry, no account beyond your Claude login, and keys live only in the OS keychain. You can read exactly what the auto-accept logic presses and what the verifier checks.
The workspace
Everything around the fleet.
Editor
CodeMirror 6 with inline AI autocomplete and AI diffs you accept or reject hunk by hunk.
Source control
Stage, commit, and walk a full git graph to review exactly what six sessions shipped.
Preview
Dev servers are auto-detected and opened inline, so you see the result without leaving Loom.
