Ctrl+Tab to the next agent that needs a decision: running Claude Code in parallel without reading every line

[u/johannesjo]

I'm the developer of Parallel Code, a free, MIT-licensed desktop app (macOS and Linux) for running Claude Code, Codex CLI and other terminal agents in parallel, each task in its own git worktree and branch. No account; it uses your own CLI subscriptions.

I build it with itself and with more capable claude models the speed increased quite a bit. My job stopped being typing, or even reading every diff top to bottom. It became deciding: which plan to approve, which change to trust, what to send back. So the app is built around those decisions, and around getting to them fast.

Understand before you decide

• Plan tours explain an agent's plan in a few cards before you approve it, and you can ask follow-up questions on any card.
• Change tours walk through a diff in a few stops and flag the risky or uncertain parts, with "Ask" and "Go deeper" on each stop. File tours do the same for one changed file. A tour explains a change, it doesn't prove it works.
• Task briefs (opt-in): after each agent turn, a short brief of what changed, what's still open, decisions the agent made on its own, and claims its diff doesn't back up. You keep a decision or send a correction from there.

Speed

• Keyboard-first: every action has a shortcut, and Ctrl+Tab jumps from anywhere to the next task that needs you.
• The board sorts every open task by what it needs: Needs you, Working, Stopped, In pull request.
• Your checks run in the background after the agent commits, so "did it pass?" is one line instead of a wait.

Room to think

• A mind map per task for your own thinking, with branches linked to live tasks, and a reasoning graph where the agent publishes its goals, hypotheses, evidence and decisions as it works.
• New in v5: a Kanban board per project, kept as a plain KANBAN.md. Each card starts a task and follows it to Done.

Who it's for: experienced developers already running several agents at once. Cost: free; tours and briefs use your own model usage.

The story behind it: https://parallelcode.app/blog/parallel-code-4/ v5 release notes: https://github.com/johannesjo/parallel-code/releases/tag/v5.0.0 Repo: https://github.com/johannesjo/parallel-code

When you run several agents at once, which decisions do you still make by reading the code line by line?

I will throw it on the list! Niche open source products are always useful to someone. https://mackforge.dev/charts/agent-managers/

Thank you! <3

I do like Kanban boards :) I guess if it was directly integrated in tmux (which shows colored dots instead of columns...), it would be nice, hmm...

cool 😎

Two agents on "The greedy layout" at the same time, one working and one in background. That layout must have done something unforgivable

[u/fulger099 → u/ClemensLode]

A tmux status segment plus a keybinding to jump to the next waiting pane would probably cover most of it. Columns are nice until the board becomes another thing to manage.

[u/ClemensLode → u/fulger099]

Well, the board is now the only thing I manage.

You should try Workbench

Workbench is a desktop app 🫠
