Herdr vs Quil

Herdr is a background runtime for keeping coding agents’ terminal sessions available when you move between machines. It brings workspaces, tabs, panes, and agents into one terminal interface, with status labels that distinguish working, blocked, and idle agents. Herdr says it detects 22 agent command-line tools out of the box, including Claude Code, Codex, Cursor, OpenCode, Grok, Copilot, and Hermes. Panes and processes continue running when a client detaches, and saved layouts can be restored after a server restart. Integrations can report session identities for resuming after a restart, and some also report agent state. You can add SSH-accessible machines and view their workspaces alongside local ones. The runtime includes a local socket API and CLI for scripts, tools, and agents. It is free under the Apache License 2.0 and runs on macOS, Linux, and Windows. Pane screen history is off by default because terminal output may include sensitive information. Herdr Cloud is described as coming soon.

Quil is a free, open-source terminal multiplexer for developers coordinating multi-tool workflows alongside AI coding assistants. It continuously saves tabs, panes, working directories, and layout, then restores that workspace after a host reboot. AI panes for Claude Code, OpenCode, and Codex can resume sessions after daemon restarts. Built-in pane types include terminals, those AI tools, SSH, Stripe CLI, lazygit, hunk, k9s, and lazysql. Its MCP server lets compatible clients such as Claude Desktop, Claude Code, and Cursor interact with a running Quil session. Users can define pane types in TOML plugin files, which reload when saved. A command palette can find panes and tabs and search scrollback across panes. Quil runs on Linux, macOS, and Windows; remote attach over SSH to Linux or macOS is marked beta. It has no hosted version or cloud account and stores workspace state locally under ~/.quil/. The maker says it has no telemetry or database. Docker sandboxing is available for Claude Code, Codex, and OpenCode, but network egress is not bounded and users supply the container image.
