yothere vs DIY parallel Claude Code (tmux + worktrees)

You can absolutely build this yourself. Open five tmux panes, give each Claude Code session its own git worktree so the branches never collide, and you are running agents in parallel today, for zero extra dollars. Plenty of engineers work exactly this way, and for a desk-bound day it is a strong setup. yothere uses the same mechanics underneath (a worktree per code thread, parallel sessions on your machine), so this page is not going to tell you the mechanics are impossible. The difference is everything wrapped around them.

What the DIY stack does well

Full control, zero third parties, zero subscription beyond the agent you already pay for. Every session is right there in a pane; nothing is abstracted away from you. If your work style is one deep task with occasional side quests, and you are physically at the machine all day, the DIY stack may be all you need.

Where it breaks

You are the attention router. Five panes means polling five panes. A session that asked a question forty minutes ago sits blocked while you are heads-down in another pane; a finished session idles because nothing tells you it finished. The scheduling problem does not go away because the agents are parallel, it just moves into your head.

And the router only works while you sit at it. Step away for lunch, a commute, or a workout, and the whole system pauses with you: tmux has no inbox, no phone, no voice, and no way to say “only interrupt me at a real fork”.

There is also no policy layer. Each raw session decides for itself what needs your sign-off. Nothing between five agents and the outside world holds an outgoing email, a post, or a push until a human approves it.

What yothere wraps around the same mechanics

• An inbox instead of panes. Up to five turns advance at once; only the thread that hit a real fork, wrote a draft, or finished reaches you. Everything else moves silently. Your replies run on their own lane, so answering one thread never queues behind the other four.
• The router follows you. The cockpit runs in any browser and installs on your phone; a push deep-links to the one blocked thread. Hosted voice (120 minutes a day) runs the whole loop hands-free: dispatch, hear the inbox read back, approve a draft by saying so.
• The worktree lane, built in. Register a repo once and every code thread gets its own worktree and branch automatically, commits, and hands the diff back. You press Ship it; the push and PR run as you, outside the agent’s turn.
• A policy layer. A send-gate holds outward actions until you approve them, and an agent can never git push, no matter what you click. Daily and per-thread cost caps are on by default.

Side by side

	tmux + worktrees	yothere
Parallel sessions	Yes, one per pane	Yes, up to five turns advancing
Who routes attention	You, by polling panes	The inbox; only blocked threads reach you
Away from your desk	The system pauses with you	Cockpit, phone push, voice keep the loop running (machine stays on)
Worktree isolation	You script it per session	Automatic per code thread
Approvals for outward actions	Each raw session’s own prompts	One send-gate; agents can never push
Cost caps	None	Daily + per-thread, on by default
Price	$0 on top of your agent subscription	$20/mo after a 7-day free trial

When DIY is the right call

If you are at the machine anyway, poll your panes happily, and want no third party in the loop, keep the tmux setup and spend the $20 on coffee. The honest pitch for yothere starts where your attention runs out: more tasks than eyes, or any need to leave the desk while the fleet keeps working.

FAQ

Does yothere use git worktrees too?

Yes. Every code thread runs in its own worktree under ~/.yothere/worktrees/, on its own branch, so it never touches your working tree or another thread’s. Same isolation you would script by hand, without the scripting.

Can I keep my tmux setup next to yothere?

Yes. yothere is a service plus a cockpit; it does not own your terminal. Your own interactive sessions, tmux included, run exactly as before, on the same agent login.

Do I have to move or re-clone my repos?

No. You register a repo you already have (yothere workspace add site ~/code/my-site); yothere never clones and holds no git credential of yours.

Is the parallelism actually different from mine?

Mechanically no: sessions on your machine, isolated by worktrees. The difference is the routing (an inbox of only-blocked threads, a separate lane for your replies) and the policy layer (send-gate, never-push rule, cost caps).
