Version: 1.0.0
Platform: Windows 64-bit
Release Date: May 2025
4GB of source code, super fast. I flattened this app, 500,000+ lines. One clean file. Zero crashes.

- Handled a 4GB folder full of code in seconds
- One-click flattening of massive directories
- Custom viewer lets you browse, search, and export by line range
Stack2Flat was built to help tame the modern AI workflow. Feeding AI file-by-file through the chat window just doesn’t scale.
Stack2Flat gives you control. Point to any folder and flatten it. You’ll get one clean file with:
- A smart header for AI context
- File hierarchy labels at the top of each section
- Support for filtering by extension

Whether you’re prepping a dev stack or your entire server, Stack2Flat makes it one step. We even built a dedicated viewer to handle gigabyte-sized files.

It’s not just a flattener — it’s a context delivery system for AI. View instantly in Stack2Viewer. Export clean ranges.

🚧 What's Missing in the Free Version?
The Community Edition of Stack2Flat gives you the core flattening functionality — but it’s been trimmed down to keep things light and focused.

- No built-in Stack2Viewer
- No Advanced Options (file type filtering, instruction input)
- No automated chunk exporting or token controls
It's perfect for simple use cases — and a great way to explore the workflow before going full-stack.
Upgrade to the full version when you're ready for power features.
