The AI code editor
Cursor locks you into one AI. Copilot locks you into GitHub. 1DevTool is the AI code editor that runs Claude Code, Codex CLI, Gemini CLI, Amp, and any CLI agent you want — side-by-side in persistent terminals, inside a full Monaco editor with an HTTP client, 13-engine database client, and embedded browser. $49 one-time.
$49 one-time after beta. macOS, Windows, Linux.
Sound familiar?
One AI, one editor, one subscription
Cursor ($20/mo) ties you to Anthropic + OpenAI with opinionated routing. Copilot ($19–39/mo) ties you to GitHub and OpenAI. Windsurf locks you to Codeium. Across three editors you'd pay $600+/year for AI features that are already included in your existing Claude Pro or ChatGPT subscription.
AI lives in a sidebar, not your workflow
Inline completions are a 2023 pattern. Agentic coding means spawning an autonomous agent that plans, edits files, runs tests, and iterates — while you review. Most editors still treat AI as a plugin; 1DevTool treats it as a first-class terminal pane.
Your tools are still scattered
Editor in one window. Terminal in iTerm2. HTTP requests in Postman. DB queries in DBeaver. Browser DevTools in Chrome. Your AI agent sees none of that. Every context switch costs you focus, and every screenshot you paste costs you a prompt.
An AI code editor built for agents
- Monaco editor (same engine as VS Code) with syntax highlighting for 100+ languages and LSP for 10
- Run Claude Code, Codex CLI, Gemini CLI, Amp, OpenCode, Cline, Qoder, Aider in parallel terminals
- Send-to-AI: one click sends console logs, network requests, DB rows, and screenshots into your agent's input
- Persistent terminal sessions (tmux-backed on macOS/Linux) that survive restarts, crashes, and reboots
- Built-in HTTP client, 13-engine database client, embedded Chromium browser, Docker manager, Git client
- $49 one-time — no monthly subscription, no per-seat pricing, no AI token upcharge

Frequently asked questions
What is the best AI code editor in 2026?
It depends on your workflow. For inline completions inside VS Code, Copilot is fine. For single-agent editing with opinionated routing, Cursor works. For agentic coding — running Claude Code, Codex, or Gemini CLI autonomously with full project context — 1DevTool is purpose-built: multi-agent terminals, persistent tmux sessions, Send-to-AI from browser/HTTP/DB, and a $49 one-time price instead of a $20/mo subscription.
How is 1DevTool different from Cursor or Copilot?
Cursor and Copilot lock you into specific AI models with subscription pricing. 1DevTool runs any CLI-based AI agent — Claude Code, Codex, Gemini, Amp, Aider, Ollama — and bundles an HTTP client, database client, embedded browser, Docker manager, and Git client that Cursor and Copilot don't have. Pricing is $49 one-time instead of $19–20/month.
Does the AI code editor support Claude Code?
Yes — Claude Code is a first-class agent with a dedicated launcher, persistent tmux-backed sessions, and Send-to-AI integration. Screenshots from the embedded browser, JSON from the HTTP client, and query results from the database client all drop directly into Claude Code's input.
Can I run multiple AI agents at once?
Yes. That's a core feature. Open Claude Code in one terminal pane, Codex CLI in another, and a shell in a third — all in a grid layout. The Terminal Dashboard shows each agent's state (running, waiting, completed) so you can manage parallel work visually. Agent Pipelines let you chain agents automatically (planner → implementer → reviewer).
Does 1DevTool have AI autocomplete?
1DevTool focuses on agentic coding — running full AI agents like Claude Code that autonomously write, test, and debug code. Inline completions are de-emphasized; pair with Copilot or Supermaven inside Monaco if you want that. Most agentic users find completions redundant once they're running an agent.
Can I use 1DevTool as my only editor?
Yes. Monaco (the same engine as VS Code) handles the editing, LSP covers 10 languages, and the 18 built-in developer utilities (JSON formatter, JWT decoder, regex tester, etc.) cover the rest. Many developers use 1DevTool as their primary workspace.
What platforms does this AI code editor support?
macOS Apple Silicon (M1/M2/M3/M4) and Intel, Windows 10/11 (NSIS installer + portable .exe), and Linux (.deb + AppImage). Tmux-backed session persistence is available on macOS and Linux.
Is there a free tier?
Yes, permanently. The free tier includes 2 projects, 4 terminals per project, 2 browser tabs, 3 channels, 10 Send-to-AI actions per day, and 500 lifetime messages. No credit card required.
The AI code editor that runs every agent — not just one
$49 one-time. Claude Code, Codex, Gemini, and any CLI agent. Every tool you need in one window.
