BackgrindClaude Squad vs Backgrind: tmux sessions or an overlay?
Claude Squad is the terminal purist's session manager: a free, open-source TUI (~8k GitHub stars) that runs multiple Claude Code, Codex, Gemini, and Aider agents in isolated tmux sessions and git worktrees, with review-before-apply and an auto-accept mode. Backgrind takes the opposite bet: your agent belongs in a GUI overlay floating over whatever you're doing — even a borderless-fullscreen game — with ambient toasts, phone access, and approvals that learn. Same CLIs underneath, opposite philosophy on top.

What Claude Squad does better
Claude Squad nails its brief. One brew install claude-squad and the
cs TUI manages every local agent you own — Claude Code, Codex, Gemini, Aider —
each task in its own tmux session and its own git worktree, "so no conflicts." You can review
changes before applying them and checkout changes before pushing, or flip on auto-accept and
let tasks finish in the background. It composes with everything else in your terminal, it's
AGPL-3.0 open source with roughly 8k GitHub stars, and it costs nothing.
If your reaction to "Electron overlay" is a wince, Squad is honestly the tool for you. Backgrind is a GUI by design, it's closed source, and it doesn't automate worktrees — with us, isolation is two git commands you run yourself, then a tab per worktree.
What Backgrind does better
Claude Squad's model still assumes a terminal has your attention — you check the list, you
preview, you accept. Backgrind is built for when no terminal is visible at all: the agent
floats always-on-top over your editor, browser, or a borderless-fullscreen game, and
flashes and chimes only when something
actually needs you. Ghost mode passes your clicks through to the app underneath while the
"needs a decision" toast stays tappable; a held PreToolUse approval is answerable
from the toast, the chat, a hotkey, or
your phone over an
end-to-end-encrypted Live pairing.
Where Squad offers global auto-accept, Backgrind's policy engine is the scalpel: "Always allow" mints a rule scoped to repo · tool · command, deny beats allow, and every auto-decision is audited — hands-off exactly where you've decided to be. On top of that sit things with no TUI equivalent: the Fleet grid across every session, the Fusion council (your own CLIs answer one hard question read-only, plus any OpenRouter model on your key, and a chairman judges one verdict), voice input, and the hosted Grindy agent (Pro) for machines where you don't want to install or authenticate any CLI. And Backgrind runs natively on Windows — no tmux, no WSL.
Or run both
This pairing is more natural than it looks: Squad is a workflow, Backgrind is a presence. Plenty of terminal-native developers keep Squad for branch hygiene during focused work, then lean on Backgrind when they get up — the same underlying CLIs, worktrees intact, but the approvals and "done" pings now land on top of whatever they're doing, or on their phone. If you're choosing one: choose by where you want to be when the agent needs you.
Claude Squad vs Backgrind — FAQ
Is Claude Squad free?
Yes — Claude Squad is free and open source under AGPL-3.0, installable via Homebrew (brew install claude-squad, runs as cs). It requires tmux and the GitHub CLI (gh). Backgrind has a free in-app demo, then Plus at $9/mo ($90/yr) and Pro at $29/mo ($290/yr, adds the hosted Grindy model, unlimited parallel agents, and cloud sync).
Does Backgrind use tmux or git worktrees like Claude Squad?
No to both. Claude Squad gives each task its own tmux session and git worktree so parallel agents never conflict. Backgrind runs each agent in its own PTY inside a daemon that survives the UI closing — sessions pin to folders you pick, and if you want worktree isolation you create the worktrees yourself and point a tab at each.
Claude Squad has auto-accept ("yolo") mode — what is Backgrind’s equivalent?
Backgrind’s policy engine is the deliberate version of it: instead of one global auto-accept, every "Always allow" becomes a rule scoped to that repo, tool, and command, deny rules beat allow rules, and every auto-decision lands in an audit trail. You get the hands-off effect where you have chosen it, without a blanket yes to everything.
Can I run the same CLIs in both?
Largely, yes — both wrap your real, locally installed agent CLIs. Claude Squad manages Claude Code, Codex, Gemini, Aider and other local agents in tmux; Backgrind wraps Claude Code and Cursor today (Codex marked coming soon) and adds the hosted Grindy agent on Pro if you want no CLI at all.
Let the agents grind.
Backgrind floats your real CLI over whatever you're doing and taps you only when an agent needs a decision. Free in-app demo — no sign-up to try it.
