The best way to run Claude Code
Stop running Claude Code in scattered iTerm or Terminal tabs. 1DevTool is a dedicated desktop workspace for Anthropic Claude Code — with named terminals, persistent sessions, per-project organization, and parallel agent support on macOS, Windows, and Linux.
$29 one-time after beta. macOS, Windows, Linux.
Sound familiar?
Lost Claude Code sessions
You close your laptop, reopen it, and your Claude Code session is gone. All that context, MCP servers, and in-flight tool calls — lost.
Terminal tab chaos
Which terminal was running Claude Code for which project? You have 12 tabs in iTerm and no idea which is which.
No multi-project organization
Claude Code runs great — but organizing three projects with two agents each is on you. There's no concept of a workspace in a stock terminal.
Can't run agents in parallel cleanly
Running Claude Code + Codex + Gemini side-by-side in terminal tabs means constant cmd-tab between windows and manual pane arrangement every morning.
No visibility into long-running tasks
When Claude Code is midway through a 20-step plan, you can't glance across terminals to check who's blocked, who's waiting for input, or who finished.
1DevTool fixes this
- Named Claude Code terminals that persist across app restarts and reboots
- Per-project workspaces — switch projects in one click, agents resume exactly where they left off
- Color-coded tabs so you always know which agent is running in which repo
- Run Claude Code alongside Codex CLI, Gemini CLI, or any CLI-based agent
- Flexible layouts: 2×2 grid, columns, tabs, or fullscreen — optimized for parallel agents
- Built-in browser, HTTP client, and database tools for end-to-end dev without context switching
Everything you need for claude code
Persistent Claude Code Sessions
Your Claude Code terminals survive restarts. Named, colored, exactly where you left them — including MCP server connections.
Per-Project Workspaces
Every project gets its own workspace. Switch instantly without losing Claude Code context or restarting agents.
Multi-Agent Parallelism
Run Claude Code alongside Codex CLI, Gemini CLI, and any other AI agent — in the same window, same workspace.
Flexible Layouts
2×2 grid, columns, or fullscreen. Arrange your Claude Code terminals for the task — refactor, debug, review.
Integrated Browser & HTTP Client
Test the endpoint Claude Code just generated without leaving the window. Inspect requests, replay them, debug in place.
Fast Native Build
1DevTool is a native desktop app — not an Electron-wrapped web page. Claude Code output renders instantly even during heavy tool calls.
Frequently asked questions
What is the best desktop app for Claude Code in 2026?
1DevTool is purpose-built for running Claude Code and other CLI-based AI agents. It gives you named persistent terminals, per-project workspaces, parallel agent layouts, and integrated browser + HTTP + DB tools — everything Anthropic's CLI doesn't ship in a stock terminal.
Does 1DevTool replace Claude Code?
No. 1DevTool is a workspace that runs Claude Code. You still need Claude Code installed and authenticated with Anthropic. 1DevTool just organizes it much better than a stock terminal.
Can I run multiple Claude Code instances in parallel?
Yes. Spawn as many Claude Code terminals as you want — each named, color-coded, and persistent. Ideal for driving multiple agents through the same codebase on different tasks.
Does 1DevTool work with Claude Code's latest version?
1DevTool runs whatever version of Claude Code you have installed — it does not ship or bundle the CLI itself. When Anthropic ships a new Claude Code release, update via npm and 1DevTool picks it up automatically.
What about Codex CLI, Gemini CLI, and other agents?
1DevTool supports any CLI-based AI agent. Run Claude Code, OpenAI Codex CLI, Google Gemini CLI, Aider, or your own agent — all in the same workspace, side by side.
Does it work on macOS, Windows, and Linux?
Yes. 1DevTool ships native builds for macOS (Apple Silicon and Intel), Windows 10/11, and Linux. Claude Code runs identically across all three.
Will 1DevTool work with Claude Code MCP servers?
Yes. MCP servers are configured inside Claude Code itself, not 1DevTool. 1DevTool simply hosts the Claude Code process — your MCP setup works untouched.
How much does it cost?
1DevTool is a one-time $29 purchase with a free trial. No subscription, no per-seat pricing. Claude Code itself is billed separately by Anthropic based on your API usage.
