⭐ Stack2Flat — Flatten Massive Folders. View Like a Pro.

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.
