@lawrencecchen 🔥🔥🔥

In the next version of cmux You can define custom actions to replace the "+" new workspace button and tab bar buttons And you can right-click the "+" button to run custom actions This means you can bring your own worktree, multiple checkouts, or SSH setups to cmux and have them open in the exact layout you want All custom actions are also available in cmd+shift+p

@hawaalidrammeh stealing this to be one of my 3-4 voicelines 🤣

prompt engineering -> agent engineering -> harness engineering -> factory engineering? -> company engineering?? -> ...?

Introducing cmux Claude Code Agent Teams: `cmux claude-teams --dangerously-skip-permissions` Teammates/subagents spawn as native cmux pane splits. They stack vertically in a right column and auto-equalize as agents spawn and exit. `cmux claude-teams` automatically sets CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1 and shims tmux on PATH with cmux's tmux-compat layer, so you don't need to update your Claude config. All arguments forward to Claude Code, and it works over cmux SSH too. Out in the latest version of cmux (0.63.x).

Introducing cmux SSH: `cmux ssh user@remote` You can now drag images into SSH'd Claude Code sessions, and cmux will automatically upload them via scp. And when you start a dev server on the remote machine, the browser pane in cmux can reach it at localhost:3000 without port forwarding. The workspace kinda becomes the remote machine, so split panes/new tabs automatically open remote shells. Out in the latest version of cmux (0.63).

met 2 cmux users randomly at claude code anonymous! (and @steipete, though he doesn't use cmux, yet...) if you're in sf and down to meet and talk about cmux, please dm me!

@aidenybai awesome to see forks! github.com/manaflow-ai/cm…

My favorite cmux feature is Cmd+Shift+U. I have 17 workspaces open right now, each running an agent. I used to click through tabs and macOS system-wide notifications to figure out what completed. But with cmux, I can just "Cmd+Shift+U" Cmd+Shift+U jumps to the newest unread notification. In practice that means the last agent that finished. It switches to the right workspace, focuses the exact pane, flashes it so you see where to look, and marks it read. If the notification came from another window, that window comes forward.

cmux is not prescriptive about how developers hold their tools. It's a terminal and browser with a CLI, and the rest is up to you. cmux is a primitive, not a solution. It gives you a terminal, a browser, notifications, workspaces, splits, tabs, and a CLI to control all of it. cmux doesn't force you into an opinionated way to use coding agents. What you build with the primitives is yours. The best developers have always built their own tools. Nobody has figured out the best way to work with agents yet, and the teams building closed products definitely haven't either. The developers closest to their own codebases will figure it out first. Give a million developers composable primitives and they'll collectively find the most efficient workflows faster than any product team could design top-down.

cmux just launched on product hunt! Would greatly appreciate an upvote 🙏 producthunt.com/products/cmux

めちゃ優秀な友人達が作った、Claude Codeガチ勢のための専用ターミナル「cmux」 ブラウザがターミナル内で開けたり、通知が来たり、応答待ちのエージェントをハイライトしたり、色々な便利機能搭載。Ghosttyベースなのもイケてる！ （実は自分がtmux大好きなのでcmuxの命名を手伝いました😎）

@lawrencecchen YESSS arc for terminal lesgooo

Introducing cmux: the open-source terminal built for coding agents. - Vertical tabs - Blue rings around panes that need attention - Built-in browser - Based on Ghostty When Claude Code needs you, the pane glows blue and the sidebar tells you why. No Electron/Tauri. Just Swift/Appkit.

@austinywang looks awesome, wonder if this is possible with video too

Announcing Preview: a GitHub bot that comments UI screenshots on your PRs. Today’s senior engineers are overwhelmed with manually reviewing frontend PRs. Preview automatically spins up your dev server in a VM, reads the diff, and navigates to relevant pages to capture UI screenshots for your PRs.

@lawrencecchen @jobergum ooo excitinggg 👀👀

@jobergum cmux.dev i'll make mobile app over holidays

A hosted service that is super easy to onboard that gives you a sandbox to run your coding agents in for asynchronous agentic coding. Also ships a mobile app for iOS/Android. Who’s building this?

@CroissantLoL @riotgames @LeagueOfLegends congrats!! excited to get my riot buddy 😁😁

I'm super hyped to share that last month I joined @RiotGames as a Game Designer on @LeagueofLegends Thank you to everyone who's shared their love of the game with me, you've added to mine and I wouldn't be here otherwise, truly. I'll do my best, and hope to share more soon -🥐

Life update: I'm leaving behind esports. It's been hard to put into words, to crystallize the bittersweet feelings of closure. Still, it's easy to count my blessings, to close my eyes and remember all the players, staff, and fans that have touched my life. As for what's next..

@lawrencecchen but to be fair if there was an edge case a human was there to handle it 🥸

robotaxi handled this perfectly. bitter lesson?

@lawrencecchen @xai @austinywang awesome stuff!!! congrats 🎉

i won the @xai hackathon by making an X feed for grok code introducing manaflowX. a curated algorithmic feed that lets AIs escalate the most urgent tasks for human review. built with @austinywang
