If you use AI coding agents like Claude Code, Codex CLI, Gemini CLI, or Amp, you probably have a mess of terminal windows scattered across your screen.
Switching between projects means losing context, and there's no easy way to see what all your agents are doing at once. I kept closing everything at the end of a session and spending the first 10 minutes of the next one just getting back to where I was.
So I built something to fix that.
What is 1DevTool?
1DevTool is an Electron app that gives you a single persistent workspace per project — multiple real terminals, a file explorer, code editor, HTTP client, database client, and an embedded browser, all in one window.
The core idea: your AI agents shouldn't live in isolated terminal tabs. They should coexist in a layout you control, with full context preserved across sessions.
Key features
🔲 Multi-agent layout
Run multiple AI agents simultaneously in a 2×2 grid, columns, or single-focus layout. See everything at once.
💾 Terminal persistence
Sessions survive app restarts via tmux. Your scrollback is always there — no more re-running setup scripts every morning.
🔔 AI Activity Feed
Live notifications when any agent finishes a task or generates files, across all your active projects.
✂️ Send code to AI
Select code in the editor, right-click, and send it to any running agent — with file path and line numbers included automatically.
🔄 Resume AI sessions
Browse and continue past conversations from Claude Code, Codex, Gemini CLI, and Amp directly from the sidebar.
🧠 Skills Manager
Browse, install, and manage AI agent skills (CLAUDE.md, agent rules, etc.) with built-in security scanning.
🎨 VS Code themes
Import any .vsix theme file and it applies across the entire workspace — editor, terminal, panels.
🗄️ Database client
Connect to Postgres, MySQL, MongoDB, Redis, ClickHouse, and 8 more engines without leaving the window.
📂 Drag & drop projects
Drop a folder from Finder (or Explorer) onto the sidebar to add it instantly.
🧩 Customizable layouts
Drag panels between sidebars, save layout presets, and show/hide header items to match your workflow.
Availability & pricing
Available on macOS, Windows, and Linux.
Free tier: 1 project, 4 terminals — enough to try it with a real workflow.
Happy to answer any questions or hear feedback in the comments. If you've run into the same terminal chaos with AI agents, I'd love to know how you're currently handling it.
