About foldermap.app

foldermap.app is a structural repository scanner with one job: take a ZIP archive, a local folder, or a public GitHub repository and show you exactly what’s inside as a clean, interactive, exportable tree.

Why we built it

Anyone who has inherited a codebase, audited a client handoff, inspected a deployment bundle, or dug through a research archive knows the ritual: unzip somewhere temporary, run tree in a terminal, squint, delete. foldermap.app replaces that with a two-second scan — no install, no upload, no account.

How it works

• Advanced Structural Repository Scanning — ingest ZIP files, uncompressed folders, or public GitHub repos and normalize them into a single navigable tree model.
• Client-Side JSZip Sandbox Parsing — all extraction and node classification runs directly inside your browser tab. Nothing is sent to our servers.
• Clean Repository Outlining — convoluted, deeply nested directories become structured trees perfect for documentation, deployment logs, and architectural audits.
• High-Speed Structural Indexing — memory-efficient client-side indexing keeps large trees responsive without blocking the UI thread.
• Zero Data Exfiltration — no telemetry, file-name logs, code structures, or binary contents leave your local browser environment.
• Export the structure as JSON, Markdown, CSV, or an SVG diagram.

Who it’s for

Software engineers reviewing code drops, architects mapping monorepos, technical writers documenting projects, DevOps teams inspecting artifacts, teachers explaining repository layouts, and archivists indexing datasets — anyone who needs to see a folder structure fast without compromising privacy.
