Chains: stacked PRs
Order cards into a chain and Remux runs them as stacked PRs — each branch cut from the last, restacked when a parent merges, with an optional merge train to land the lot in order.
AI-native terminal multiplexer
Run your coding agents
in parallel.
Remux gives every agent its own pane, shows you which one is waiting on you, and turns your repo's board into live working sessions. Built for people who keep Claude Code and Gemini running all day.

What is Remux
A terminal that was built for agents, not tabs.
tmux splits your screen into panes. Remux splits it into working sessions — each one a real terminal running a real agent, with cost, context and model tracked while it works. When an agent stops to ask a question or finishes a task, Remux tells you which one and takes you there.
- Every pane is a full PTY — your shell, your tools, your scrollback.
- Claude Code and Gemini CLI get live status: context left, tokens, spend.
- The same app on macOS, Windows and Linux.

Input required
Agent is waiting for your input — Migrate jobs table
-
01
Parallel agents, side by side
Give every task its own pane and let them all run at once. No tab-cycling, no guessing which window was doing what — every session stays on screen, live.
-
02
A real terminal multiplexer
Split horizontally or vertically, nest splits as deep as you like, zoom one pane to fill the screen and back. Layouts persist across restarts — your setup is where you left it.
-
03
A status bar on every pane
Context left, session cost, tokens and the running model, pinned under each terminal and read live from the agent. You can tell what's spending and what's stuck without touching a pane.
-
04
It tells you who needs you
Remux knows the difference between an agent that's thinking and one that's blocked on a question. Needs input, finished, errored — you get a toast that jumps you straight to the pane, and an OS notification if you're in another app.
-
05
A board that turns cards into sessions
Every repo gets a board. "Work this card" starts an agent on a fresh git worktree with the card already loaded as context. Open the PR from the card, and it moves itself across the columns as reviews land and merge.
-
06
Git worktrees, colour-coded
Run agents on isolated branches without them stepping on each other. Each worktree gets an accent colour that follows it onto pane borders and chips, so parallel work never blurs together.
CI/CD beside your panes
GitHub Actions and Azure Pipelines in a side panel — run logs, cancel, re-run, dispatch with inputs — and a red dot in the titlebar the moment your branch goes red.
Usage & cost, per project
One dashboard for spend, tokens and plan-limit windows — broken down by model and by branch, so you can see exactly which work burned the tokens.
Agents can drive Remux
A built-in MCP server lets your agents file cards, comment, start runners and open PRs from inside their own sessions — the board becomes something they work with, not just you.
Project Runners
Pin your dev server, watcher or build to a headless runner with logs on tap — out of the pane tree, always one keystroke away. Agents can start and stop them too.
Inspect browser
Give an agent a real browser pane it can read and drive — so it can check its own work in the page, not just the diff.
AI Quick-Add
Describe a task in a sentence; Claude drafts a proper card — title, body, the right column — and flags likely duplicates before you create it. Paste a screenshot and it reads that too.
Resume where you stopped
Close a pane mid-session and Remux spots the previous Claude or Gemini session and offers to pick it straight back up. Turn on Resume Sessions and whole projects come back at startup.
Cross-platform, one UI
Native on macOS and Linux (Tauri + Rust), Electron on Windows. The same interface, keybindings and projects everywhere.
Remux Pro · Cloud Spaces
Your boards, on every machine. Nothing else leaves home.
Remux runs fully local by default — no account, nothing sent anywhere. Cloud Spaces is the opt-in Pro layer: promote a project and its board syncs across your machines, while your terminals, scrollback and code stay exactly where they are.
- Opt-in per project — promote the ones you want, leave the rest local.
- Boards and attachments sync; terminals and code never do.
- Automations run agents against your board behind approval gates — and a Take over button hands the session to your desktop.
- Self-serve delete: demote a project, delete it from the cloud, or wipe your account data.
Cloud Spaces is rolling out with Remux Pro. The free app stands on its own — Pro is for syncing across machines.
