PumaWorx was built to provide a consistent freelance productivity experience without the risks of cross contamination, data exfiltration, or contributing to Shadow-IT. These tools are designed for a frictionless start when you need them and will work from wherever you put them.
Three rules every app in the suite follows. They're not optional — they're the reason PumaWorx exists.
01
Each app is one HTML file. Drop it on a USB stick, install it as a PWA, save it to your downloads folder, archive it on a NAS. Wherever a browser runs, the app runs.
02
No outbound traffic means no exfiltration risk, no third-party SaaS to vet, no remote dependencies to compromise. The browser and the file are the entire trust boundary.
03
PumaWorx is a personal passion project that helps me do what I want to do, how I want to do it, forever. Never again will the product I depend on get bought and ruined by some private capital or hijacked by internet drama.
Every app handles your data in structured plaintext formats, exports to the most common filetypes, and is built to copy/paste straight into emails, documents, and prompts with minimal friction in under 1000 KB.

OPTION 01 · LIGHTEST
Visit pumatracker.greykit.com (or any other). The app loads. You're done. Browser caches the file — works offline after the first visit.
OPTION 02 · PORTABLE
Right-click → Save Page As. You now have a portable, offline-forever copy. Open it from a USB stick, a sandboxed VM, an air-gapped laptop.
OPTION 03 · POLISHED
Desktop or phone app with auto-updates, no app store required. Chrome / Edge: Chromium: Save and Share → Install. Safari iOS: Share → Add to Home.
Most apps fit on a single 1.2 MB 5¼-inch disk. If that's important to you.
The single-page HTML IS the source. There's nothing to build, include, or compile and each app is 100% human readable with inline documentation.
