Show HN: I built TreeSnap – turn your code into a prompt ready bundle (opens in new tab)

I built over 3-4 weeks to solve my own pain point, picking up rust along the way. It has a browser version that works online/offline and cross platform desktop as well. It was a pretty intense sprint.

About TreeSnap, well it simplifies this preparation of sharing code with Chat LLMs. In my use case, making o3 via ChatGPT a lot more cost-effective to use for these tasks compared to Cursor:

How it works:

Select files/folders → generates a single text bundle + ASCII tree

Instantly shows per-file and total token counts (list & treemap views)

Quickly trim unnecessary files or folders to match context limits

Fully offline and private (Tauri desktop app)

Also available as a free browser app—offline and private

Built in ~3 weeks, I use it daily to aid my workflow and reduce my expenses by minimizing the need to rely on Cursor's pricier model usage. I still rely on Cursor with grok 3 or gemini pro 2.5 pro mostly without getting crazy with usage fees. Feedback welcome—especially UX, performance, and pricing.
