Base44 Code Downloader

Download your Base44 project source code as a ZIP directly from the Chrome tab you already have open.

This extension is built for makers who want a quick local backup, a handoff to another developer, or a starting point for moving a Base44 app into a normal Git workflow.

Version 1.0.2

• Fixed exports that missed nested directories such as src/api, src/components/ui, base44/entities, and base44/functions.
• Added automatic file-tree discovery when the direct Base44 code endpoint is unavailable.
• Preserved full folder paths and scoped file selection to the active directory, including duplicate filenames.
• Updated editor recovery to read visible code from the Base44 editor DOM.

Why People Use It

• One-click project detection from the active Base44 editor tab.
• ZIP export for easy backup and sharing.
• Automatic fallback when Base44 blocks direct file reads.
• Editor-DOM recovery mode for projects that can only be read through the editor.
• No backend, no account, no external server. Everything runs locally in your browser.

How To Download A Project

1. Open your project in app.base44.com.
2. Click the Base44 Code Downloader icon.
3. Click Detect project.
4. Click Download ZIP.

If Base44 returns 412 App does not support direct file reads, the extension automatically falls back to reading files through the editor.

Fallback Mode

Some Base44 projects do not expose the direct /code endpoint. In that case the extension can switch files in the editor and read the code from the Monaco DOM.

You can also open Emergency mode: file list, detect paths from the current page, edit the list, and download only the files you want.

Privacy

The extension reads code from the active Base44 tab and generates the ZIP locally in Chrome. It does not upload your code to any third-party service.
