The Best Herdr Alternative for a Full Visual AI Workspace
Herdr is a slick Rust multiplexer that gives every coding agent its own terminal pane and tracks their state. But it lives in the terminal — no editor, no HTTP client, no database, no browser. 1DevTool gives you the same parallel-agent workflow in a visual workspace, then adds a Monaco editor, HTTP client, 13-engine database client, and embedded browser, all wired into Send-to-AI. $29 one-time.
Why Look for a Herdr Alternative?
Terminal-only, no GUI
Herdr is a mouse-friendly TUI, but everything still lives in the terminal. There's no visual editor, no clickable tool panels, and no dashboards beyond agent-state text.
No built-in developer tools
Herdr multiplexes agents and nothing else. For editing, API testing, database work, or a browser you leave Herdr and open separate apps — and your agent can't see any of them.
No worktree isolation or pipelines
Herdr runs agents in panes, but it doesn't put each agent in its own Git worktree or chain them into planner → implementer → reviewer pipelines.
Windows is still beta
Herdr's Windows build is a beta preview; macOS and Linux are the stable targets. 1DevTool ships stable native builds for all three.

Why Switch to 1DevTool?
- ✓Keep the parallel-agent workflow, but in a full visual workspace instead of a terminal TUI
- ✓Get a Monaco editor, HTTP client, 13-engine database client, and embedded browser built in
- ✓Send-to-AI pipes an API response, DB row, or web page straight into an agent — Herdr can't
- ✓Each agent runs in its own Git worktree, and Agent Pipelines chain planner → implementer → reviewer
- ✓Tmux-backed persistence plus one-click resume of sessions started in Ghostty, iTerm, or Warp
- ✓Stable native builds for Windows, not just macOS and Linux
- ✓$29 one-time, with no AGPL obligations on how you use it
Frequently Asked Questions
Is Herdr free?
Yes — Herdr is open source under AGPL-3.0 and free to use. 1DevTool is a one-time $29 license. You're paying for the visual workspace and the integrated toolchain — editor, HTTP, database, browser — built around your agents.
What does 1DevTool add over Herdr?
Scope. Herdr multiplexes agent terminals brilliantly; 1DevTool does that too, then adds a Monaco editor, HTTP client, database client, embedded browser, Docker, Git worktree isolation, and Agent Pipelines — all connected through Send-to-AI.
Does 1DevTool track agent state like Herdr?
1DevTool shows per-terminal status and lays agents out in a visual grid so you can see what each one is doing at a glance. Herdr's dedicated blocked/working/done/idle labels are its signature feature; 1DevTool focuses on the surrounding workspace.
Can I run the same agents 1DevTool supports in Herdr?
Both are agent-agnostic. 1DevTool runs Claude Code, Codex, Gemini CLI, and any CLI agent, and it can also detect and resume agent sessions started in external terminals — something Herdr, with its own background server, doesn't do.
