agent-orchestratorDesktop agent IDE for fleets of coding agents: each task gets a worker with its own workspace and agent CLI, while a project orchestrator plans work and handles CI fixes, conflicts and reviews.
Why switchBoth drive agent work through an SDLC with gates. Fabro makes you define the graph up front and intervene only at chosen stages; AO keeps a human in a live Kanban and lets the orchestrator replan interactively.
Full comparison → contrabassTerminal-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 switchBoth run coding agents through gated, verified pipelines instead of a REPL. Contrabass is terminal-first and issue-driven (poll Linear/GitHub, worktrees, branch-advance checks); Fabro is a server with workflow graphs, ensemble models and cloud sandboxes.
Full comparison → zeroshotExecutor–verifier orchestration for code changes: a conductor classifies the task, an executor works in an isolated worktree, and a separate verifier must reproduce the evidence — looped to approval.
Why switchSame conviction — agent output must pass gates — different locus of control. In Fabro you define the SDLC graph and the gates; Zeroshot ships an opinionated conductor that sizes each task and picks the workflow for you.
Full comparison → 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 switchSame goal — multi-agent software process with human gates — opposite weight classes: Squad coordinates AI CLIs through one-shot shell commands and SQLite with no daemon; Fabro runs a persistent server with a runs board and queued 24/7 execution.
Full comparison → fractalHierarchical agent loops: nodes iterate toward a goal in their own git worktree and spawn children for subtasks — the tree grows to fit the problem. Hard caps, SQLite run log, live TUI.
Why switchOpposite philosophies of unattended multi-agent coding: Fabro encodes the process up front as a workflow graph with verification gates; fractal lets the process emerge recursively under resource caps. Predefine vs self-organize.
