Tempest

Tempest workspace: Monaco editor with LSP diagnostics, a Claude Code tab streaming a response, and the Workspaces sidebar

A native macOS workspace for developers working alongside AI coding agents. Tempest puts your terminal, editor, browser, language servers, and Git/Jujutsu tools in a single window -- and treats Claude, Codex, and Pi as first-class tabs with session resume, activity indicators, history search, and inline diff context. Built with Electrobun (Bun + native WebView).

Install

Homebrew (recommended)

brew tap MattFlower/recipes
brew install --cask tempest

Manual download

Grab the latest Tempest.dmg or Tempest.zip from the GitHub Releases page.

Features

Coding agents

Three agents -- Claude, Codex, and Pi -- running side by side as Tempest tabs

  • Three agents, one window -- Claude Code, OpenAI Codex, and Pi all run as native tabs. Launch from the + menu, command palette, or split toolbar.
  • Auto-resume -- Tempest reattaches each agent to its prior session on restart (PID/hook for Claude, session-id watcher for Codex, hook socket for Pi).
  • Activity indicators -- Per-workspace dots show whether an agent is Working, Needs Input, or Idle so you know when to come back.
  • Chat history viewer -- List, full-text search (ripgrep), and view past sessions across Claude / Codex / Pi. "Resume in new tab" relaunches any session in place.

  • AI Context in VCS -- Diff panel shows which agent edited each file and why, fanned out across all three providers.
  • Plan mode + permission prompts for Claude; per-session MCP injection (show_webpage, show_mermaid_diagram, show_markdown) lets agents render visuals into a side pane.

Editor with managed LSP

Monaco editor with an LSP hover popup and the footer LSP popover listing running language servers

  • Monaco + Vim bindings with workspace-relative path headers and persistent state.
  • Auto-installed language servers for 14+ languages -- TypeScript/JavaScript, Python, HTML/CSS/JSON, Bash, YAML, Dockerfile, Rust, Lua, C/C++, Markdown, Go, and Java. Tempest installs them on first open into ~/.config/tempest/lsp/ and shows install progress in the footer.
  • Full LSP feature set -- hover, go-to-definition, find references, diagnostics, rename, completions, signature help, inlay hints, code actions, and document symbols. Vim bindings (gd, gr, K, gO, gK, ]d/[d, <leader>cr, <leader>ca) ship out of the box.
  • Per-repo LSP toggle in repository settings; global toggle in Settings → LSP.

Workspace tools

Terminal pane on the left with a URL opened as a Browser pane on the right via Cmd+click

  • Terminal -- xterm.js with WebGL rendering, backed by Bun.Terminal PTY. Cmd+click URLs to open them in a side Browser pane.
  • Browser -- Tabbed system WKWebView with bookmarks, zoom shortcuts, and split-with-terminal layouts.
  • Markdown viewer -- Live-rendered with Mermaid diagram support and Cmd+F find-in-page.

  • Find in Files -- Cmd+Shift+F opens a ripgrep-backed modal with regex/case toggles. Enter jumps to the match.

  • Run pane -- Dockable bottom pane for long-running scripts. Each script runs in its own PTY-backed tab with Restart/Stop controls; stays alive across workspace switches.

Dockable Run pane with multiple script tabs running with Restart and Stop controls

  • Custom scripts + auto-detected package.json and pom.xml scripts runnable from the green-arrow menu (modal or Run pane).

Git, Jujutsu, and PRs

VCS view with the Pull / Push / Merge / Rebase toolbar over a unified diff

  • VCS view for both Git and Jujutsu -- diffs, status, staging, file scoping, and Cmd+R refresh.
  • Pull / Push / Merge / Rebase toolbar with searchable branch dropdowns and remote pickers.
  • Revert changes from the Files sidebar context menu.
  • PR monitor -- track, review, and open pull requests directly in the workspace.

Workspaces and sessions

  • Workspace-per-task -- Each workspace has its own terminals, browser tabs, agents, and sessions. Create, archive, and switch with persistent state.
  • Session restore -- Tempest reopens exactly where you left off, including terminal scrollback (stored per-terminal under ~/.config/tempest/scrollback/).

Productivity

  • Command palette -- Cmd+Shift+P for commands, Cmd+P for files. Arrow keys target left/right pane.
  • Reassignable keybindings -- Settings → Keybindings rebinds anything, including chord sequences (⌘K ⌘S).

Settings -> Keybindings dialog with a binding being captured as a chord and a conflict warning

  • Help → Keymap lists every shortcut with a filter input.
  • Footer status row for LSP server health (restart/stop, stderr tail) and token usage.
  • Remote control server -- Optional HTTP server with bearer token auth, web dashboard, and QR code for mobile access.

Tempest
Tempest workspace: Monaco editor with LSP diagnostics, a Claude Code tab streaming a response, and the Workspaces sidebar
A native macOS workspace for developers working alongside AI coding agents. Tempest puts your terminal, editor, browser, language servers, and Git/Jujutsu tools in a single window -- and treats Claude, Codex, and Pi as first-class tabs with session resume, activity indicators, history search, and inline diff context. Built with Electrobun (Bun + native WebView).
Install
Homebrew (recommended)
brew tap MattFlower/recipes
brew install --cask tempest
Manual download
Grab the latest Tempest.dmg or Tempest.zip from the GitHub Releases page.
Features
Coding agents
Three agents -- Claude, Codex, and Pi -- running side by side as Tempest tabs
  • Three agents, one window -- Claude Code, OpenAI Codex, and Pi all run as native tabs. Launch from the + menu, command palette, or split toolbar.
  • Auto-resume -- Tempest reattaches each agent to its prior session on restart (PID/hook for Claude, session-id watcher for Codex, hook socket for Pi).
  • Activity indicators -- Per-workspace dots show whether an agent is Working, Needs Input, or Idle so you know when to come back.
  • Chat history viewer -- List, full-text search (ripgrep), and view past sessions across Claude / Codex / Pi. "Resume in new tab" relaunches any session in place.

  • AI Context in VCS -- Diff panel shows which agent edited each file and why, fanned out across all three providers.
  • Plan mode + permission prompts for Claude; per-session MCP injection (show_webpage, show_mermaid_diagram, show_markdown) lets agents render visuals into a side pane.
Editor with managed LSP
Monaco editor with an LSP hover popup and the footer LSP popover listing running language servers
  • Monaco + Vim bindings with workspace-relative path headers and persistent state.
  • Auto-installed language servers for 14+ languages -- TypeScript/JavaScript, Python, HTML/CSS/JSON, Bash, YAML, Dockerfile, Rust, Lua, C/C++, Markdown, Go, and Java. Tempest installs them on first open into ~/.config/tempest/lsp/ and shows install progress in the footer.
  • Full LSP feature set -- hover, go-to-definition, find references, diagnostics, rename, completions, signature help, inlay hints, code actions, and document symbols. Vim bindings (gd, gr, K, gO, gK, ]d/[d, <leader>cr, <leader>ca) ship out of the box.
  • Per-repo LSP toggle in repository settings; global toggle in Settings → LSP.
Workspace tools
Terminal pane on the left with a URL opened as a Browser pane on the right via Cmd+click
  • Terminal -- xterm.js with WebGL rendering, backed by Bun.Terminal PTY. Cmd+click URLs to open them in a side Browser pane.
  • Browser -- Tabbed system WKWebView with bookmarks, zoom shortcuts, and split-with-terminal layouts.
  • Markdown viewer -- Live-rendered with Mermaid diagram support and Cmd+F find-in-page.

  • Find in Files -- Cmd+Shift+F opens a ripgrep-backed modal with regex/case toggles. Enter jumps to the match.

  • Run pane -- Dockable bottom pane for long-running scripts. Each script runs in its own PTY-backed tab with Restart/Stop controls; stays alive across workspace switches.
Dockable Run pane with multiple script tabs running with Restart and Stop controls
  • Custom scripts + auto-detected package.json and pom.xml scripts runnable from the green-arrow menu (modal or Run pane).
Git, Jujutsu, and PRs
VCS view with the Pull / Push / Merge / Rebase toolbar over a unified diff
  • VCS view for both Git and Jujutsu -- diffs, status, staging, file scoping, and Cmd+R refresh.
  • Pull / Push / Merge / Rebase toolbar with searchable branch dropdowns and remote pickers.
  • Revert changes from the Files sidebar context menu.
  • PR monitor -- track, review, and open pull requests directly in the workspace.
Workspaces and sessions
  • Workspace-per-task -- Each workspace has its own terminals, browser tabs, agents, and sessions. Create, archive, and switch with persistent state.
  • Session restore -- Tempest reopens exactly where you left off, including terminal scrollback (stored per-terminal under ~/.config/tempest/scrollback/).
Productivity
  • Command palette -- Cmd+Shift+P for commands, Cmd+P for files. Arrow keys target left/right pane.
  • Reassignable keybindings -- Settings → Keybindings rebinds anything, including chord sequences (⌘K ⌘S).
Settings -> Keybindings dialog with a binding being captured as a chord and a conflict warning
  • Help → Keymap lists every shortcut with a filter input.
  • Footer status row for LSP server health (restart/stop, stderr tail) and token usage.
  • Remote control server -- Optional HTTP server with bearer token auth, web dashboard, and QR code for mobile access.

Architecture
Two-process model:
  • Bun process (src/bun/) -- Backend: PTY management, session state, file I/O, git operations, RPC handlers
  • React webview (src/views/main/) -- Frontend: UI components, state management (Zustand), terminal/browser/editor rendering
The processes communicate over Electrobun's typed RPC bridge.
