Features
foldermap.app is more than a ZIP viewer. It is a privacy-first structural scanner that turns archives, folders, and public GitHub repositories into clean, exportable, interactive maps — entirely inside your browser.
Built for serious structural work
foldermap.app treats folder structure as first-class data: scan it, outline it, index it, and export it — without ever exposing it.
Advanced Structural Repository Scanning
Ingest ZIP archives, uncompressed local folders, or public GitHub repositories and convert them into a unified, navigable tree model.
Client-Side JSZip Sandbox Parsing
All extraction algorithms and node classification evaluations process directly within your active sandboxed tab container. No file-system block leaks to cloud architectures.
Clean Repository Outlining
Convert convoluted, multi-level directory branches into clear structured tree elements optimal for software documentation mapping, deployment logs, or project architectural audit tracks.
High-Speed Structural Indexing
Engineered with efficient client memory management constraints ensuring large structural trees load quickly without causing thread blocking.
Strict Privacy & Zero Data Exfiltration Architecture
FolderMap operating rules require that zero telemetry vectors, file name logs, code structures, or binary files are uploaded onto external cloud computing farms. Your workspace calculation logic is fully encapsulated in local browser environments.
Exportable Intelligence Formats
Emit the derived structure as JSON, Markdown, CSV, or SVG diagrams so it plugs straight into documentation, wikis, CI artifacts, or audit reports.
Who it’s for
Anyone who needs to see, share, or document a folder structure fast — without compromising privacy.
Software Engineers & Architects
Audit inherited codebases, review monorepo handoffs, and document package boundaries in seconds.
Technical Writers
Generate Markdown, CSV, or SVG exports of project structure and keep docs in sync with the repo.
DevOps / SREs
Inspect deployment packages, CI artifacts, and release bundles before they reach production.
Educators & Students
Teach repository layout, file organization, and software architecture visually and interactively.
Archivists & Researchers
Index datasets, document collections, and research archives without extracting a single file.
