A dedicated terminal for Claude Code
Claude Code deserves better than a generic shell. 1DevTool is a purpose-built terminal app for Anthropic's Claude Code CLI — with one-click spawn, named persistent sessions, multi-project organization, and parallel-agent layouts on macOS, Windows, and Linux.
$29 one-time after beta. macOS, Windows, Linux.
Sound familiar?
Generic terminals aren't built for AI agents
iTerm and Terminal.app were built for bash and short-lived commands — not for long-running Claude Code sessions with 30-step plans.
Sessions don't persist
Close your terminal, lose your Claude Code context. Every reboot means re-authenticating, re-opening the repo, and losing conversation history.
No agent-aware features
Generic terminals don't know you're running Claude Code. No per-agent naming, no parallel-agent layout presets, no one-click spawn.
No project-scoped terminals
Your 'frontend' Claude Code and your 'backend' Claude Code live in the same flat tab list — you have to remember which tab maps to which repo.
Typing the launch command every time
Opening a fresh terminal, cd-ing into the repo, and typing 'claude' every single time — small friction that adds up when you use Claude Code 50+ times a day.
A terminal built for Claude Code

- Parallel-agent layouts: 2×2 grid, columns, or tabs
- Built-in project file tree that opens files in your editor of choice
- Native builds for macOS, Windows, and Linux — same Claude Code experience everywhere

Frequently asked questions
What's the best terminal app for Claude Code?
1DevTool is purpose-built for Claude Code. Unlike iTerm or Terminal.app, it ships one-click agent spawn, persistent sessions, per-project naming, and parallel-agent layouts out of the box — features you'd otherwise build yourself with tmux and shell scripts.
Is 1DevTool a replacement for iTerm or Terminal.app?
For Claude Code and other AI agent work, yes. For general shell work you might still use iTerm — but most 1DevTool users find they stop opening iTerm at all once they have named, persistent agent terminals.
Can I customize the terminal appearance?
1DevTool ships a Dracula-inspired dark theme tuned for long Claude Code sessions. Color-coded tabs help you tell agents and projects apart at a glance.
Does it support terminal multiplexing like tmux?
1DevTool has built-in layouts — 2×2 grid, columns, tabs, fullscreen — without the complexity of a tmux config. You can still run tmux inside a 1DevTool terminal if you want nested panes.
Does it work with Claude Code MCP servers and subagents?
Yes. MCP is configured inside Claude Code itself. 1DevTool simply hosts the Claude Code process, so your MCP servers and subagent configuration work untouched.
Can I run Claude Code terminals side-by-side with Codex or Gemini?
Yes — 1DevTool is multi-agent by design. Put Claude Code, Codex CLI, and Gemini CLI in a 2×2 grid and watch all three agents work in parallel on the same codebase.
How much does it cost?
One-time $29 purchase with a free trial. No subscription, no per-seat pricing. Claude Code API usage is billed separately by Anthropic.
