1DevTool
1DevTool is a purpose-built multi-agent workspace: Charts, teams, pipelines, Conversation Mode, Autopilot, and 20 CLI agents — plus DB (23 engines), HTTP, browser profiles, Docker, and a Repo panel for pull requests and CI. It sits beside your editor, not inside it. Free plan, Pro from $29 one-time.
VS Code + Copilot
VS Code with GitHub Copilot extension adds inline AI completions to Microsoft's popular editor. Requires VS Code + Copilot subscription ($19-39/month).

How to run 1DevTool beside VS Code
VS Code stays your editor. 1DevTool runs and watches the agents working on the same folder.
- 1
Add the project
In 1DevTool, add the folder you already have open in VS Code.
- 2
Give risky work its own worktree
Start Claude Code, Codex or another agent from Add Terminal. Put a risky task in its own Git worktree and switch worktrees from the status bar.
- 3
Turn on Autopilot
In the Dashboard's AI Diagnosis tab, switch on Autopilot so a crashed or disconnected agent is restarted on the same tab with its session resumed.
- 4
Review in VS Code
Files change on disk, so VS Code picks them up. Agent Changes in 1DevTool tells you which agent touched which file.
- 5
Use the tools VS Code needs extensions for
Query the database, send HTTP requests and check the page in the built-in browser, then send the result to an agent.

Frequently asked questions
Do I need to leave VS Code to use 1DevTool?
No. 1DevTool runs alongside VS Code. Use Copilot for inline help while typing; use 1DevTool for parallel agents, Charts, and built-in DB/HTTP/browser tools.
Can 1DevTool run Claude Code and Codex while I stay in VS Code?
Yes. Agents run in 1DevTool terminals with Charts and pipelines; your files stay on disk for VS Code to edit.
Is 1DevTool a one-time purchase?
There is a free plan; Pro is $29 one-time for 1 device ($59 / 3, $89 / 5). Copilot remains a monthly subscription on top of free VS Code.
Does 1DevTool need tmux installed?
1DevTool uses tmux-backed persistence under the hood for sessions that survive restart. You do not need to learn tmux keybindings or maintain a config.
What about browser and database tools?
1DevTool includes a 23-engine database client, HTTP client, and embedded browser with per-tab profiles — none of which Copilot adds to VS Code by itself.
What happens if an agent crashes while I am working in VS Code?
With Autopilot on, 1DevTool notices a crashed or disconnected agent, restarts it on the same tab with its session resumed, and sends it back to work. AI Diagnosis explains agents stuck on a quota wall or a sign-in prompt.
