Zeron alternatives.
Zeron is a free, open-source native app that drives Claude Code, Codex and the rest through their own protocols, as chats in tabs with a live branch diff, and follows your sessions across machines. People look elsewhere when they want the agent’s own CLI in a terminal, every agent in view at once on a canvas, recaps and handoffs, or their agents on a phone.

Questions
Which Zeron alternatives are free?
AgentGrid is free for 3 projects, Maestri is free for 1 workspace, Conductor is free locally, Superset is free for one user, Emdash is free and open source (Apache 2.0) and 49Agents is free to self-host (BSL 1.1). Starkomand is one payment per Mac, after 3 free days with every feature.
Which Zeron alternatives run on Windows or Linux?
Beyond macOS: AgentGrid (Windows and Linux), Maestri (Windows and Linux builds), Superset (Linux, as an experimental AppImage), Emdash (Windows and Linux) and 49Agents (any browser, against a server you host). Starkomand runs on macOS with Apple silicon only, for now.
Which Zeron alternatives keep the agent’s own CLI?
Starkomand, AgentGrid, Maestri, Superset, Emdash, CNVS and 49Agents run the agent’s own CLI in a terminal. Conductor draws its own chat view over it instead.
What is the closest alternative to Zeron?
Emdash: free, open source and on every desktop too, with a git worktree per task and diff review, but it runs the agent’s own CLI in a terminal instead of a chat view.
