Installation

Getting 1DevTool running on your machine takes about 2 minutes. Follow the steps below for your operating system.

System Requirements

Before downloading, check that your machine meets these minimums:

If your computer can run a modern web browser, it can run 1DevTool.

Download

Go to 1devtool.com/download and click the download button for your platform. The download is a single file — no package manager or command line required.

macOS

1. Open the downloaded .dmg file. A window appears showing the 1DevTool icon.
2. Drag 1DevTool into your Applications folder.
3. Open 1DevTool from Applications or Spotlight — press Cmd+Space, type "1DevTool", press Enter.
4. If you see a "cannot be verified" warning: macOS shows this for apps downloaded outside the App Store. It doesn't mean anything is wrong. To open it:
   • Open System Settings (the gear icon in your dock)
   • Go to Privacy & Security
   • Scroll down and find the message about 1DevTool being blocked
   • Click "Open Anyway"
   • Enter your password if prompted
   • 1DevTool will launch and this warning won't appear again

Tip: 1DevTool runs natively on Apple Silicon (M1/M2/M3/M4) — no Rosetta needed. You get full native performance on your Mac.

Windows

1. Run the downloaded .exe installer. Windows may ask "Do you want to allow this app to make changes?" — click Yes.
2. If Windows Defender SmartScreen shows a blue warning ("Windows protected your PC"): this appears for apps that are new or not yet widely distributed. The app is safe. Click "More info" then click "Run anyway".
3. Follow the installer steps — click Next, leave the install location as the default (or change it), then click Install.
4. 1DevTool launches automatically when the install finishes. A desktop shortcut is also created for future use.

Linux

Linux uses an AppImage — a single self-contained file that works on almost any modern Linux distribution without installing anything system-wide.

1. Download the .AppImage file from 1devtool.com/download.
2. Open a terminal and make the file executable:
   bash

   chmod +x 1DevTool-*.AppImage
   

3. Run it:
   bash

   ./1DevTool-*.AppImage
   

Note: On some systems you may see an error about FUSE. AppImages require FUSE to run. Install it with:

bash

sudo apt install libfuse2

Then run the AppImage again.

First Launch

When 1DevTool opens for the first time, you'll see an empty workspace — no projects added yet, no terminals open. That's completely normal. The next step is adding your first project.
