Lightweight terminals
for vibe coding.
Run a fleet of AI coding agents in parallel — each one isolated in its own git worktree and branch, all from one tidy sidebar. No more juggling fifteen terminal tabs.
Completely simple, entirely useful.
Workspaces & sessions
Open any git repo as a workspace, branch off as many sessions as you need — all nested neatly in the sidebar.
Beautiful terminals
GPU-accelerated via libghostty. Crisp, fast, no janky redraws — even with a wall of panes open.
Isolation with worktree
Every session checks out its own git worktree and branch. Run five agents at once without any of them touching each other's files.
Git diff for reviewing code
A right-side, Cursor-style diff panel shows exactly what each agent changed, file by file, before you trust it.
Open with VS Code, Cursor, or Xcode
One click opens the workspace or worktree folder in whichever editor you already live in.
Forever updates
Pay once — $4.99. No subscription, no renewal. Sparkle quietly keeps you on the latest build.
One sidebar. Every agent.
Workspaces hold your repos; sessions are the branches you're running agents on. Color-code workspaces and nest as many sessions as you want — your whole fleet, one glance away.
Parallel agents, zero collisions.
Each session checks out its own git worktree on its own branch. Run Claude Code in five sessions at once — none of them can stomp on your main branch or each other.
Trust, but diff.
A right-side diff panel — rendered in its own isolated helper process — shows exactly what changed, file by file, before you merge anything an agent wrote.
