Not publicly distributed yet. No paywall.
Waitlist at https://t.co/nw1uNcGfG9: if it resonates I'll ship it properly. Early testers get a free lifetime license.
Does this solve a real problem for you? What's missing?
Honest feedback welcome.
#BuildInPublic#indieDev#macos
I built a macOS terminal workspace because my dev setup was driving me crazy.
5 apps open. Context everywhere. iTerm, VS Code, Arc with 50 tabs, a Git GUI, tmux running somewhere I'd forgotten about.
Nothing put it all together. So I built it. >>
I use Claude Code and Codex daily. I don't want to rebuild their UI: it's already great.
Nexion is the layer around it: visual tmux, pane layouts, notifications, SSH, browser, files.
Nexion notifies you on any terminal event: builds, errors, process exits. With AI bots like Claude or Codex, notifications are rich: messages, questions, and input requests in a floating toast

Every account you juggle — all logged in, same window, at the same time.
Nexion browser profiles have completely isolated cookie stores. No extensions. No containers. No "which account am I in right now?"
👉 Unlimited profiles. Zero logout cycles.
#GitHub#DevTools#macos
Bonus for the config-as-code crowd: Workspaces save as JSON in .nexion/workspaces/. Commit with the repo. Share with the team.
New hire clones → same panes, same ssh, same startup commands. Onboarding in one git pull.
Old morning ritual: open terminal, split 3 panes, cd everywhere, run dev server, ssh into staging, tmux attach to the long-running AI.
Now: click "Activate". 1 second. Done.
Nexion Workspaces. Visual layout, saved once. tmuxinator without YAML.
#BuildInPublic#NativeApp#ai
Nexion plugins = a full SDK in your workspace 🧬
15+ native APIs: editor, git, ssh, tmux, fs, UI, commands…
Sandboxed JSContext per plugin. UI never blocks.
Custom linter? K8s panel? Write it in JS, drop it in.

Your terminal is from 1978.
Your IDE is an Electron tab.
Your AI coding agent lives in a sidebar begging for context.
We ripped the whole stack out and rebuilt it.

#developerexperience#aiagents#coding
Developers using AI agents lose flow in one place: context switching.
Terminal in one app.
Browser in another.
Git in another.
Nexion brings all into one native macOS workspace.

@joshm@arcinternet@browsercompany I'm very sorry. I loved (and still love) Arc to the point of madness. But I can't use a project that's been declared deprecated, and I can't invest time in an abandoned project that its creators have deemed a failure. And I can't wait for DIA.
