squadMulti-agent terminal collaboration for AI CLIs: a manager, workers and an inspector — Claude Code, Gemini, Codex, OpenCode — coordinating through one-shot shell commands and SQLite. No daemon.
Why switchBoth coordinate fleets of local coding-agent CLIs in the terminal; Squad does ad-hoc manager/worker collaboration over SQLite with no daemon, Contrabass dispatches from Linear/GitHub issues with worktrees, retries and branch-advance verification.
Full comparison → pullfrogOpen-source, model-agnostic GitHub bot: tag @pullfrog on any issue or PR and your own coding agent (BYOK) runs the task inside GitHub Actions, context via an internal MCP server.
Why switchSame job — turn tracker issues into coding-agent runs. Pullfrog executes per @-mention inside GitHub Actions; Contrabass polls continuously and runs agents on your own machine in tmux panes and git worktrees.
Full comparison → FusionA multi-agent software factory: describe a task, agents plan (PROMPT.md), build, review and merge in isolated worktrees — kanban + graph board, missions, agent chat rooms, any model. Early preview.
Why switchSame job — dispatch coding agents into isolated git worktrees with review gates — opposite philosophies: Contrabass is a lean terminal orchestrator fed by Linear/GitHub issues; Fusion is a full board-driven factory with visual workflows, missions and agent chat.
Full comparison → alookSelf-hosted collaboration layer that turns local coding agents (Claude Code, Codex, OpenCode) into an always-on "AI company" — per-agent email, org chart, kanban, shared memory.
Why switchBoth turn local coding agents into a coordinated team working a shared board; alook is an always-on collaboration layer (per-agent email, kanban, shared memory), Contrabass is a leaner issue-queue dispatcher with per-run verification and retries.
