Run parallel coding agents
in one desktop window.
Hangar wraps the Claude Code and Codex CLIs you already pay for. Parallel sessions in isolated git worktrees — streaming chat, diffs, terminal, review — with your hooks, skills, subagents, MCP, and subscription intact.
Fix the flaky session-restore e2e test
Working on it — turn 1.

Subagent scanned the repo and found the fixed 500 ms wait in restore.spec.ts.

Dispatch. Glance. Review. Merge.
01
A tiled workspace for many agents
Sessions live side by side — up to four tiles per workspace, grouped by project in the sidebar with live status. Kick off an agent in one project while three others stream in parallel.
02
Every session in its own worktree
Isolation by default: each agent works on its own branch with per-turn checkpoint
commits, so you can rewind any turn — or race the same task across Claude and Codex
with /best-of-n and keep the winner.
03
Review that talks back
A changed-files panel and diff viewer where your inline comments are fed back to the agent as a structured follow-up. Annotate the diff, hit send, and the agent revises — then stage, commit, or open the PR.
04
Your CLI, not our API keys
Hangar drives the claude and codex binaries you already
have as subprocesses. Hooks, skills, subagents, MCP servers, and subscription billing
all keep working — we never touch ~/.claude.
why we're building it
Cursor's Agents Window proved the shape: the control plane for agents, not the text editor, is the primary surface. Hangar takes that shape and grounds it in the CLIs you already trust — open in approach, desktop-native, subscription-friendly.
MIT-clean
Learn from everything, copy nothing.
Local-first
Your repos, your machine, your keys — SSH when you want it.
Transparent
Usage gauges, hooks timeline, subagent inspector. See the machinery.
The hangar doors open soon.
First builds go to the early-access list. No spam — one email when it ships.
