BuildFootprint — Game Project Size & Duplicate Asset Auditor

BuildFootprint is an offline, browser-based audit tool for solo and indie game developers.

Choose a game project or exported-build folder and quickly see:

• total project size and file count

• largest files

• footprint by file extension

• exact duplicate files and potential reclaimable space

• image dimensions and decoded RGBA-memory estimates

• review flags for large files and oversized images

• CSV and JSON audit exports

Privacy-first: selected files stay on your machine. The tool contains no network requests and does not upload project files.

Non-destructive: BuildFootprint never deletes, renames, or modifies your project. It identifies cleanup candidates so you decide what to change.

Works best in a current Chromium-based desktop browser such as Chrome, Edge, or Brave.

Limitations: this is a folder-level audit, not an engine dependency graph. Image-memory estimates are simple decoded RGBA estimates and do not model engine-specific compression or mipmaps. Exact duplicate hashing is capped at 250 MB per candidate file.
