Agent integration

Your agents, at a glance. Mix and match coding agents from different providers. See who’s working, who’s finished, and who needs your input. Follow their tool calls without switching between panes.

Start a session. Or pick one up. Nyx installs agent hooks automatically. Launch an agent or resume a previous session from your workspace.

Know when you’re needed. Get notified when an agent needs attention. Click to jump straight to its pane.

Stay organized

Keep each project together. Give your shells, agents, and browser panes a workspace of their own. Switch projects without closing your work, or open an agent in a fresh worktree to try a new idea.

Keep it minimal. Or go all out. Start with a single shell or spread your work across tabs and split panes.

Multiple projects, one place. Give each project its own workspace and keep them running side by side.

Built-in browser

Build and check, side by side. Open your app beside its code and dev server. Give your agent access to the same browser so it can inspect the page, try an interaction, and check its changes where you can see them.

Built-in browser

Connected through NYX MCP. Register NYX MCP with your agent CLI. It communicates over stdio and connects to the app through a local Unix socket.

Browser context, on demand. Enable agent access to share page snapshots and browser logs. NYX MCP tools let your agent navigate, click, and type in the same browser pane you’re using.

NYX MCP

Give your agents more capabilities. Bring coding agents from different providers into one workspace. Through NYX MCP, one agent can delegate to another, send instructions, and read the results. Choose the agents you want for implementation, review, and testing.

With NYX MCP connected, try asking

“Set up my workspace for frontend development, with a dev server, an agent, and a browser preview.”

“Hermes, ask Claude to fix this bug in another pane, then check its work and run the tests.”

“Open a fresh worktree for this idea in its own tab. Keep my current work running.”

“Check the output in the test pane, ask the coding agent to fix any failures, then run the tests again.”

Hermes coordinates the workspace

I’ll split the work across three panes and check their progress.

Your workspace, under agent control. NYX MCP tools let an agent create and arrange panes, send terminal input, and read output. An agent it starts can use those same tools to delegate further.

Control with clear boundaries. Agents can control panes they create or that you explicitly unlock. Your other terminal panes stay private, and browser access has its own permission.

Everyday details with great defaults and no bloat.

Splits and tabs
Arrange panes, resize them freely, or send input to several at once.
Shell integration
zsh, bash and fish work out of the box. Starship is bundled too.
Themes and type
Choose from 40+ built-in themes, create your own, and use the monospace fonts you love.
Search and navigation
Search scrollback with regex, jump between prompts, and open paths in your editor.
Profiles and shortcuts
Save your shell, folder and environment. Rebind shortcuts to suit your hands.
Snippets
Keep useful commands close and bring them back without retyping.
Session recording
Record and replay terminal output in asciicast format. Input events are not captured.
A drop-down terminal
Bring a terminal over any app with a single shortcut.
Images and links
View inline images and open links directly from terminal output.
Live configuration
Use native settings or edit a plain text config that reloads as you save.
Command palette
Find workspaces, switch tabs, and run commands from one keyboard-driven menu.
Room to focus
Zoom into a pane, then return to your split layout. Use focus mode to reduce distractions.
Completion notifications
Get notified when a background task finishes or an agent needs your attention.
Command output selection
Select the last command’s output in one action, ready to copy and share.
