The AI IDE
Traditional IDEs bolt AI on as a sidebar plugin. 1DevTool is the AI IDE — a workspace designed from the ground up for developers who code with Claude Code, Codex CLI, and Gemini CLI. Multi-agent terminals, persistent sessions, and an integrated toolchain for the agentic era.
$29 one-time after beta. macOS, Windows, Linux.
Sound familiar?
VS Code wasn't built for AI agents
You're running AI agents in integrated terminals, but they're an afterthought. No first-class support for agent state, parallel agents, or Send-to-AI from other tools.
AI agents deserve primary status, not plugin status
Claude Code and Codex aren't autocomplete helpers — they're autonomous agents that plan, edit, and test. They need their own pane, not a sidebar popup.
Context switching between tools
Terminal in iTerm, browser in Chrome, API client in Postman, DB in TablePlus, editor in VS Code. Your AI agent sees none of that — so you screenshot and paste, repeatedly.
Cursor and Copilot lock you to one AI
Cursor decides which model to route to. Copilot hardcodes OpenAI. Windsurf locks you to Codeium. When a new agent ships (Amp, OpenCode, Qoder) you're stuck.
Subscription stack keeps growing
Cursor $20/mo + Copilot $19/mo + Postman Pro + TablePlus + GitKraken = $50–80/month before you write a line of code. 1DevTool is $29 one-time.
An IDE built for AI-native development
- Monaco editor (same engine as VS Code) with LSP, syntax for 100+ languages, and multi-cursor
- AI agents are first-class: Claude Code, Codex CLI, Gemini CLI, Amp, Aider in parallel panes
- Named, color-coded, persistent terminals per agent — tmux-backed on macOS/Linux
- Built-in HTTP client, 13-engine database client, embedded Chromium browser, Docker, Git
- Per-project workspaces with full-state persistence across restarts
- Send-to-AI: one click sends screenshots, HTTP requests, DB rows, and logs directly into your agent's input
Everything you need for ai ide
AI-First Design
Every feature built with AI agents in mind. Not a terminal emulator with AI bolted on.
Multi-Agent Workspace
Run Claude Code, Codex CLI, Gemini CLI, Amp, Aider, and custom agents side by side in a 2×2 grid.
Monaco Editor with LSP
Same editor engine as VS Code. Syntax for 100+ languages, multi-cursor, IntelliSense, Go-to-Definition across 10 languages via LSP.
Integrated Toolchain
HTTP client, database client (13 engines), embedded browser, Docker manager, Git client. One window, zero app switching.
Persistent Sessions
Tmux-backed on macOS/Linux. Terminals, agent state, open files, HTTP tabs, DB connections — all restore exactly where you left them.
Send-to-AI
Click a screenshot, HTTP response, or DB row and send it straight into your agent's input — no copy-paste, no screenshot juggling.
Frequently asked questions
What is the best AI IDE in 2026?
It depends on workflow. For inline completion inside VS Code, Copilot works. For single-model editing, Cursor is fine. For agentic coding — running Claude Code, Codex, or Gemini CLI as autonomous agents with full project context — 1DevTool is purpose-built: multi-agent terminals, persistent tmux sessions, integrated HTTP/DB/browser, and a one-time price.
Is 1DevTool a replacement for VS Code or Cursor?
1DevTool can replace both — Monaco editing, LSP, and 18 built-in dev utilities cover most editor needs. You can also use 1DevTool alongside VS Code or Cursor, opening files in your editor of choice with one click.
What makes this an 'AI IDE'?
1DevTool is designed specifically for running AI coding agents as first-class panes, not sidebar plugins. Named terminals, parallel-agent layouts, persistent sessions, Send-to-AI from every tool, and an agent-aware dashboard — built for agentic workflows.
Which AI agents does it support?
Any CLI-based AI agent: Claude Code, OpenAI Codex CLI, Google Gemini CLI, Amp, OpenCode, Cline, Qoder, Aider, and any custom tool. Local models via Ollama and LM Studio work as custom agents.
How is this different from a terminal like iTerm?
Organization, persistence, and integration. Named terminals, color-coding, per-project workspaces, tmux-backed persistence, plus a Monaco editor, HTTP client, database client, and browser — none of which iTerm offers.
Does 1DevTool have AI autocomplete?
It focuses on agentic coding — autonomous agents like Claude Code that plan, edit, and test. Inline completions are de-emphasized; pair with Copilot or Supermaven inside Monaco if you want that.
What platforms does it run on?
macOS (Apple Silicon and Intel), Windows 10/11, and Linux (.deb + AppImage). Tmux-backed persistence is available on macOS and Linux.
How much does it cost?
Free tier available. $29 one-time purchase for 1 device, $78.30 for 3 devices, $116 for 5 devices. No subscription, no token markup — bring your own Anthropic, OpenAI, or Google keys.
