Our verdict on Terminalz

Terminalz is a self-hosted terminal multiplexer for people who want browser access to terminals across multiple machines. A lightweight Rust agent runs on each computer and connects to the web control plane through an outbound authenticated WebSocket, so inbound machine ports are not required. The product supports web, macOS, Linux, and self-hosted environments, with collaboration, local persistence, and access across tmux and Herdr environments. It is a strong fit for users who organize terminal work in Herdr or tmux and want one browser-based view of those sessions.

Its ecosystem fit is the clearest strength. Terminalz supports local tmux sessions and can mirror Herdr spaces, sessions, tabs, panes, layouts, ordering, and statuses. Docker Compose can deploy the web control plane, while Homebrew or GitHub Releases can install the native agent. The browser connection includes reconnect checkpoints and compressed WebSocket frames, and the system provides allowlisted filesystem and runtime operations. These pieces make Terminalz suited to multi-machine terminal access while keeping the workflow centered on established terminal environments rather than replacing them.

Terminalz is more focused than a broad remote workspace platform. Its persistence scope is local, and each connected computer needs its own agent, so setup involves both the self-hosted control plane and machine-level installation. Typed operations can create, rename, and close runtime objects, but the product remains centered on terminal sessions and their organization. Choose Terminalz if browser streaming, Herdr mirroring, tmux support, and collaborative session access are the priorities. Choose an alternative if you need a wider application workspace or a workflow that does not depend on Herdr, tmux, or self-hosted infrastructure.
