Free Android developer tools

In short: Free tools for Android developers, testers and people building AI agents, that work in your browser with no sign-up. They write adb, scrcpy and am commands for your shell, look up permissions and screen densities, generate MCP client configuration and compare device lab costs. They never run anything themselves; you copy the result into your own terminal.

Commands

Commands written for your shell, ready to copy. They run on your computer, never on this site.

• ADB command builderInstalls, logcat filters, screenshots, Wi-Fi pairing and more, for one phone or every phone, in bash or PowerShell.
• ADB intent and deep link builderam start and am broadcast with extras, flags and deep links, quoted for the phone and your shell.
• scrcpy command builderMirror a screen, a camera or a virtual display with scrcpy 4.1’s options, or one window per phone.

How these tools work

• They write; you run. Every command is shown in full before you copy it, quoted for bash, PowerShell or Command Prompt where that matters. Commands that delete data or cannot be undone carry a warning.
• Nothing leaves your browser. The tools are part of this page's code: no uploads, no accounts and nothing stored.
• Sources are named. Options follow the documentation of the version each tool names, such as scrcpy 4.1 or Android's own references, with links to them.

These tools are made by the team behind BenchFleet, a desktop app that shows, controls and automates many Android phones from one computer. New to adb?

Questions

Are these tools really free?

Yes. There is no sign-up, no limit and no trial; each tool is a page on this site that works in your browser.

Do the tools run commands on my phone?

No. They write commands and configuration; you run them in your own terminal with adb, scrcpy or your AI client. Nothing on this site connects to your phones.

Is what I type sent anywhere?

No. The tools run in your browser and send and store nothing, so package names, serial numbers, links and tokens stay on your computer.
