Fusion alternatives
Curated alternatives to Fusion — and why you'd switch.
contrabass
Terminal-first orchestrator for issue-driven AI coding-agent runs — polls Linear/GitHub, runs Codex/OpenCode in git worktrees with retries and verification. Go/Charm rebuild of OpenAI's Symphony.
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.

A fully autonomous 'AI company' on your own PC: 14 expert-modeled agents ideate, decide, code, deploy and market 24/7 — driven by Claude Code or Codex CLI, with a local dashboard.
Why switchBoth run autonomous 'AI companies' on your hardware: Auto-Company ships 14 expert-modeled agents ideating and shipping 24/7; Fusion makes the company importable and inspectable — org charts, token share per agent, multi-agent chat rooms.
